The Company and Description of Business	1. The Company and Description of Business The accompanying consolidated financial statements include the accounts of Quest Resource Holding Corporation (“QRHC”) and its subsidiaries, Quest Resource Management Group, LLC (“Quest”), Landfill Diversion Innovations, LLC (“LDI”), Youchange, Inc. (“Youchange”), Quest Vertigent Corporation (“QVC”), Quest Vertigent One, LLC (“QV One”), and Quest Sustainability Services, Inc. (“QSS”) (collectively, “we,” “us,” or “our company”). Operations We are a national provider of waste and recycling services to customers from across multiple industry sectors that are typically larger, multi-location businesses. We create customer-specific programs and perform the related services for the collection, processing, recycling, disposal, and tracking of waste streams and recyclables. In addition, we offer products such as antifreeze and windshield washer fluid and other minor ancillary services. We also provide information and data that tracks and reports the detailed transactional and environmental results of our services and provides actionable data to improve business operations. The data we generate also enables our customers to address their environmental and sustainability goals and responsibilities. Our principal office is located in The Colony, Texas within the Dallas metroplex. In March 2020, the World Health Organization categorized Coronavirus Disease 2019 (“COVID-19”) as a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. The waste management and recycling services we provide are currently designated an essential critical infrastructure business under the President’s COVID-19 guidance, the continued operation of which is vital for national public health, safety and national economic security. The extent of the impact of the COVID-19 outbreak on our operational and financial performance will depend on certain developments, including the duration and spread of the outbreak, its impact on our customers and subcontractors, and the range of governmental and community reactions to the pandemic, which are uncertain and cannot be fully predicted at this time. On October 19, 2020, Quest acquired substantially all of the assets used in the business of Green Remedies Waste and Recycling, Inc. (“Green Remedies”), a leading provider of independent environmental services, particularly in multi-family housing, located in Burlington, NC. See Note 3 for more information regarding the acquisition.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Principles of Presentation and Consolidation The consolidated financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The accompanying consolidated financial statements include the operating activity of QRHC and its subsidiaries for the years ended December 31, 2020 and 2019. As QRHC, Quest, LDI, Youchange, QVC, QV One, and QSS each operate as environmental-based service companies, we did not deem segment reporting necessary. Accounting Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could materially differ from those estimates. We use significant estimates when accounting for the carrying amounts of accounts receivable, goodwill and other intangible assets, stock-based compensation expense, deferred taxes, and the fair value of assets and liabilities acquired in asset acquisitions, all of which are discussed in their respective notes to the consolidated financial statements. Revenue Recognition We recognize revenue as services are performed or products are delivered. For example, we recognize revenue as waste and recyclable material are collected or when products are delivered. We recognize revenue net of any contracted pricing discounts or rebate arrangements. We generally recognize revenue for the gross amount of consideration received as we are generally the primary obligor (or principal) in our contracts with customers as we hold complete responsibility to the customer for contract fulfillment. We record amounts collected from customers for sales tax on a net basis. Cash and Cash Equivalents We consider all highly liquid instruments with a maturity of three months or less when purchased to be cash equivalents. Accounts Receivable We follow the allowance method of recognizing uncollectible accounts receivable, which recognizes bad debt expense based on a review of the individual accounts outstanding and our prior history of uncollectible accounts receivable. We extend credit based on an evaluation of each customer’s financial condition, and our receivables are generally unsecured. Accounts receivable are stated net of an allowance for doubtful accounts in the consolidated balance sheets. We consider accounts past due if outstanding longer than contractual payment terms. We record an allowance based on consideration of a number of factors, including the length of time trade accounts are past due, our previous loss history, the creditworthiness of individual customers, economic conditions affecting specific customer industries, and economic conditions in general. We charge-off accounts receivable after all reasonable collection efforts have been exhausted. We credit payments subsequently received on such receivables to bad debt expense in the period we receive the payment. As of December 31, 2020 and 2019, we had established an allowance of $935,261 and $767,464, respectively, for potentially uncollectible accounts receivable. We record delinquent finance charges on outstanding accounts receivable only if they are collected. In the year ended December 31, 2020 we recorded a $47,940 increase in our allowance for doubtful accounts related to certain receivables acquired in the Green Remedies acquisition as further described in Note 3. The changes in our allowance for doubtful accounts for the years ended December 31, 2020 and 2019 were as follows: Years ended December 31, 2020 2019 Beginning balance $ 767,464 $ 929,339 Bad debt expense 120,936 60,000 Uncollectible accounts written off, net (1,079 ) (221,875 ) Addition related to acquisition 47,940 — Ending balance $ 935,261 $ 767,464 Fair Value Measurements ASC Topic 820, Fair Value Measurements Level 1: Quoted prices in active markets for identical assets or liabilities; Level 2: Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3: Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect our own estimate of assumptions that market participants would use in pricing the asset or liability. Property and Equipment We record property and equipment at cost. We provide for depreciation on the straight-line method, over the estimated useful lives of the assets. We amortize leasehold improvements over the shorter of the estimated useful life or the remaining term of the related leases. We charge expenditures for repairs and maintenance to operations as incurred; we capitalize renewals and betterments when they extend the useful life of the asset. We record gains and losses on the disposition of property and equipment in the period incurred. We report assets held for sale, if any, at the lower of the carrying amount or fair value less costs to sell. The useful lives of property and equipment for purposes of computing depreciation are as follows: Vehicles 5 to 7 years Computer equipment 3 to 5 years Office furniture and fixtures 5 to 7 years Machinery and equipment 5 to 7 years Leasehold improvements 5 to 7 years Impairment of Long-Lived Assets We analyze long-lived assets, including property and equipment and definite-lived intangible assets, which are held and used in our operations, for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. We review the amortization method and estimated period of useful life at least at each balance sheet date. We record the effects of any revision to operations when the change arises. We recognize impairment when the estimated undiscounted cash flow generated by those assets is less than the carrying amounts of such assets. The amount of impairment is the excess of the carrying amount over the fair value of such assets. We did not recognize any impairment charges for long-lived assets during 2020 and 2019. Goodwill We record as goodwill the excess of (i) the consideration transferred, the amount of any non-controlling interest in the acquiree, and the acquisition date fair value of any previous equity interest in the acquired entity over the (ii) fair value of the net identifiable assets acquired. We do not amortize goodwill; however, annually, or whenever there is an indication that goodwill may be impaired, we evaluate qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. Our test of goodwill impairment includes assessing qualitative factors and the use of judgment in evaluating economic conditions, industry and market conditions, cost factors, and entity-specific events, as well as overall financial performance. We performed our most recent goodwill impairment analysis in the third quarter of 2020, utilizing an income approach with no impairment recorded. We believe that the discounted cash flow method best captures the significant value-creating activities we are undertaking. The primary assumptions in our income approach included estimating cash flows and projections. We determined that the fair value of our goodwill exceeded our carrying value, and consequently, no impairment was deemed to have occurred. However, a prolonged period of declining gross margins or a significant decrease in our anticipated revenue growth could result in the write-off of a portion or all of our goodwill and other intangible assets in future periods. Net Income (Loss) per Share We compute basic net income (loss) per share using the weighted average number of shares of common stock outstanding plus the number of common stock equivalents for Deferred Stock Units, or “DSUs”, during the period. We compute diluted net income (loss) per share using the weighted average number of shares of common stock outstanding during the period, adjusted for the dilutive effect of common stock equivalents. Dilutive potential common shares consist of the incremental common shares issuable upon the exercise of outstanding stock options. Dilutive potential securities are excluded from the computation of earnings per share if their effect is antidilutive. The dilutive effect of outstanding stock options and warrants is reflected in diluted earnings per share by application of the treasury stock method. Concentrations Financial instruments that potentially subject us to credit risk consist principally of cash, cash equivalents, and trade accounts receivable. We deposit our cash with commercial banks. Cash deposits at commercial banks are at risk to the extent that the balances exceed the Federal Deposit Insurance Corporation insured level per institution. The bank cash balances on deposit may periodically exceed federally insured limits, such as $6,875,321 at December 31, 2020; however, we have never experienced any losses related to these balances. We sell our services and products primarily to customers without requiring collateral; however, we routinely assess the financial condition of our customers and maintain allowances for anticipated losses. From year to year, the customers that exceed 10% of our annual revenue, if any, may change. The following table discloses the number of customers that accounted for more than 10% of our annual revenue and their related receivable balances for the years ended December 31, 2020 and 2019: Customers Exceeding 10% of Revenue Year Number of Customers Revenue Combined Percent Accounts Receivable Combined Percent 2020 3 51 % 27 % 2019 3 53 % 36 % We believe we have no significant credit risk in excess of recorded reserves. Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets and current and long-term operating lease liabilities on our consolidated balance sheets. We currently do not have any material finance lease arrangements. Operating lease ROU assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate in effect at the commencement date of the lease in determining the present value of future payments. When we have the option to extend the lease term, terminate the lease before the contractual expiration date, or purchase the leased asset, and if it is reasonably certain that we will exercise the option, we consider these options in determining the classification and measurement of the lease. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Income Taxes We recognize deferred tax assets and liabilities for the future tax consequences of temporary differences between the book and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. We establish valuation allowances to reduce a deferred tax asset to the amount expected to be realized. We assess our ability to realize deferred tax assets based on current earnings performance and on projections of future taxable income in the relevant tax jurisdictions. These projections do not include taxable income from the reversal of deferred tax liabilities and do not reflect a general growth assumption but do consider known or pending events, such as the passage of legislation. We review our estimates of future taxable income annually. We first analyze all tax positions to determine if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of any related appeals or litigation processes. After the initial analysis, we measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Our income tax returns are subject to adjustment under audit for approximately the last three years. If we are required to pay interest on the underpayment of income taxes, we recognize interest expense in the first period the interest becomes due according to the provisions of the relevant tax law. If we are subject to payment of penalties, we recognize an expense for the amount of the statutory penalty in the period when the position is taken on the income tax return. If we did not recognize the penalty in the period when the position was initially taken, we recognize the expense in the period when we change our judgment about meeting minimum statutory thresholds related to the initial position taken. Advertising We charge our advertising costs to expense when incurred. During the years ended December 31, 2020 and 2019, advertising expense totaled $51,247 and $20,364, respectively. Stock-Based Compensation We measure all share-based payments, including grants of options to purchase common stock and the issuance of deferred stock units to employees, third parties and board members, using a fair value-based method, in accordance with ASC Topic 718, Stock Compensation We estimate the fair value of stock options using the Black-Scholes-Merton valuation model. Significant assumptions used in the calculation are as follows: • We determine the expected term in accordance with SEC Staff Accounting Bulletin No. 107 using the simplified method for plain vanilla options by the average of the contractual term and vesting period of the award as appropriate statistical data required to properly estimate the expected term was not available; • We measure the expected volatility using the historical changes in the market price of our common stock; • We use the implied yield on zero-coupon U.S. Treasury bonds with a remaining maturity equal to the expected term of the awards to approximate the risk-free interest rate; and • We recognize the effects of forfeitures in compensation cost when they occur. Deferred Stock Units Effective September 1, 2019, nonemployee directors can elect to receive all or a portion of their annual retainers in the form of DSUs. The DSUs are recognized at their fair value on the date of grant. Director fees deferred into stock units are calculated and expensed each month by taking fees earned during the month and dividing by the closing price of our common stock on the last trading day of the month, rounded down to the nearest whole share. Each DSU represents the right to receive one share of our common stock following the completion of a director’s service. Business Combinations Our acquisition of the assets of Green Remedies was accounted for in accordance with ASC Topic 805, Business Combinations. In purchase accounting, identifiable assets acquired and liabilities assumed are recognized at their estimated fair values at the acquisition date, and any remaining purchase price is recorded as goodwill. In determining the fair values of assets acquired and liabilities assumed, we make significant estimates and assumptions, particularly with respect to long-lived tangible and intangible assets. Critical estimates used in valuing tangible and intangible assets include, but are not limited to, future expected cash flows, discount rates, market prices and asset lives. See Note 3 for more information related to our acquisition. Our consolidated financial statements include the results of operations from the date of the acquisition. We expense all acquisition-related costs as incurred in selling, general and administrative expenses in the consolidated statements of operations. Recently Issued Accounting Pronouncements Adopted In July 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-11 Earnings per Share (Topic 260). On January 1, 2020, we adopted ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40) of the hosting arrangement, including periods covered by renewal options that are reasonably certain to be exercised. This guidance also requires entities to present the expense in the same line item in the statement of operations as the fees associated with the hosting arrangement and classify payments for capitalized implementation costs in the statement of cash flows in the same manner as payments made for fees associated with the hosting element. T In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. the London Interbank Offered Rate (“LIBOR”). The amendments are elective and apply to all entities that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The expedients and exceptions provided by the amendments generally do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. As further discussed in Note 7, our ABL Facility provides procedures for determining a replacement or alternative rate in the event that LIBOR is unavailable. As such, we do not expect the transition away from LIBOR to have a material impact on our consolidated financial statements. Pending Adoption In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326) In December 2019, the FASB issued ASU 2019-12, Income Taxes – (Topic 740), which simplifies the accounting for income taxes by removing certain exceptions and amending guidance to improve consistent application of accounting over income taxes. This guidance is effective January 1, 2021 with early adoption permitted. T There have been no other recent accounting pronouncements or changes in accounting pronouncements that have been issued but not yet adopted that are of significance, or potential significance, to us.

Business Combinations [Abstract]
Acquisition	3. Acquisition On October 19, 2020, we acquired substantially all of the assets of Green Remedies (the “Green Remedies Assets”) pursuant to the Asset Purchase Agreement (the “Asset Purchase Agreement”), dated as of October 19, 2020, among the Company, Green Remedies and Alan Allred (the “Acquisition”). Green Remedies is a leading provider of independent environmental services, particularly in the multi-family housing market, and is located in Burlington, NC. The acquisition strengthens our presence across key markets, particularly in multi-family housing. The total purchase price for the Green Remedies Assets was approximately $16.1 million at close, which includes an earn out estimate tied to future performance over the next three years. As of December 31, 2020, we paid $10.9 million in cash and recorded $5.2 million in accrued liabilities for deferred payments due to the previous owner. We funded the acquisition primarily with a term note to Monroe Capital, as further discussed in Note 7, which is secured by a first priority lien on substantially all of QRHC’s tangible and intangible assets. The following table sets forth the purchase consideration paid and the amount of assets acquired and liabilities assumed as of the acquisition date: Sources of consideration paid: Cash (1) $ 10,869,599 Payable to seller (2) 296,284 Seller's Note, net (3) 2,170,000 Deferred seller consideration (4) 2,290,000 Deferred consideration - earn out 440,000 $ 16,065,883 Purchase price allocation: Accounts receivable, net 1,331,190 Machinery and equipment 1,270,705 Intangible assets 5,890,000 Goodwill 8,101,895 Current liabilities (527,907 ) $ 16,065,883 (1) Financed with Monroe Loan (2) Working capital adjustment (3) Gross principal is $2,684,250, recorded net of OID calculated using discounted cash flow method (4) Gross consideration is $2,684,250, recorded at fair value using discounted cash flow method The purchase price has been allocated based on an estimate of the fair value of assets acquired and liabilities assumed as of the acquisition date. The intangible assets acquired were valued using an income approach; specifically, the multi-period excess earnings method for valuing the customer list and the relief from royalty method for valuing the trademark. The key assumptions used to value the customer list at $5,480,000 included, among others, attrition rates, average customer life, and discount rate. The key assumptions used to value the trademark at $410,000 included, among others, revenue projection, pretax royalty rate, and discount rate. Goodwill represents the amount by which the purchase price exceeds the estimated fair value of the net assets acquired and primarily reflects future synergies. The goodwill related to the Green Remedies assets is deductible for income tax purposes. Deferred consideration payable to the seller includes $2,290,000 net payable in either cash or shares of our common stock, and an earn-out not to exceed $2,250,000 over an earn-out period, as defined in the Asset Purchase Agreement. We valued the earn-out liability at $440,000 using a Monte Carlo simulation. As the earn-out liability is a contingent consideration arrangement, it is subject to periodic revaluation in accordance with ASC 820 Fair Value Measurement We incurred acquisition and integration costs of approximately $550,000, which is included in Selling, General and Administrative expense in the year ended December 31, 2020. The following table presents unaudited pro forma information for the years ended December 31, 2020 and 2019 as if the Acquisition had occurred at the beginning of our 2019 fiscal year. The unaudited pro forma information includes adjustments for amortization expense on definite lived intangible assets acquired, interest expense on debt incurred related to the acquisition, and the related income tax effects. The unaudited pro forma financial information is presented for informational purposes only and is not necessarily indicative of the operating results or financial position that would have occurred if the Acquisition had been effected on the dates previously set forth, nor is it indicative of the future operating results or financial position in combination.

Each loan under the revolving credit facility bears interest, at the borrowers’ option, at either the Base Rate, plus the Applicable Margin, or the LIBOR Lending Rate for the Interest Period in effect, plus the Applicable Margin, in each case as defined in the BBVA Loan Agreement. The maturity date of the revolving credit facility is April 19, 2025. The revolving credit facility contains an accordion feature permitting the revolving credit facility to be increased by up to $10 million. • An equipment loan facility in the maximum principal amount of $2.0 million. Loans under the equipment loan facility may be requested at any time until August 5, 2023. Each loan under the equipment loan facility bears interest, at the borrowers’ option, at either the Base Rate, plus 1.75%, or the LIBOR Lending Rate for the Interest Period in effect, plus 2.75%. The maturity date of the equipment loan facility is April 19, 2025. Certain of QRHC’s domestic subsidiaries are the borrowers under the BBVA Loan Agreement. QRHC and one of its domestic subsidiaries are guarantors under the BBVA Loan Agreement. As security for the obligations of the borrowers under the BBVA Loan Agreement, (i) the borrowers under the BBVA Loan Agreement have granted a first priority lien on substantially all of their tangible and intangible personal property, including a pledge of the capital stock and membership interests, as applicable, of certain of QRHC’s direct and indirect subsidiaries, and (ii) the guarantors under the BBVA Loan Agreement have granted a first priority lien on the capital stock and membership interests, as applicable, of certain of QRHC’s direct and indirect domestic subsidiaries. The BBVA Loan Agreement contains certain financial covenants, including a minimum fixed charge coverage ratio. In addition, the BBVA Loan Agreement contains negative covenants limiting, among other things, additional indebtedness, transactions with affiliates, additional liens, sales of assets, dividends, investments and advances, prepayments of debt, mergers and acquisitions, and other matter customarily restricted in such agreements. The BBVA Loan Agreement also contains customary events of default, including payment defaults, breaches of representations and warranties, covenant defaults, events of bankruptcy and insolvency, change of control, and failure of any guaranty or security document supporting the BBVA Loan Agreement to be in full force and effect. Upon the occurrence of an event of default, the outstanding obligations under the BBVA Loan Agreement may be accelerated and become immediately due and payable. The ABL Facility bears interest, at our option, at either the Base Rate, as defined in the BBVA Loan Agreement, plus a margin ranging from 0.75% to 1.25% (3.0% as of December 31, 2020), or the LIBOR Lending Rate for the interest period in effect, plus a margin ranging from 1.75% to 2.25% (no borrowings as of December 31, 2020). The BBVA Loan Agreement replaced our Loan, Security and Guaranty Agreement, dated as of February 24, 2017, with Citizens Bank, National Association (the “Citizens Bank Loan Agreement”), which was paid off and terminated effective August 5, 2020. We recorded $167,964 in loss on extinguishment of debt in connection with this loan termination, including the write-off of the unamortized portion of debt issuance costs and fees directly associated with the loan payoff. As of December 31, 2020, the ABL Facility borrowing base availability was $12,816,237, of which $4,299,333 principal was outstanding. LIBOR is expected to be discontinued after 2021. The ABL Facility provides procedures for determining a replacement or alternative rate in the event that LIBOR is unavailable. However, there can be no assurances as to whether such replacement or alternative rate will be more or less favorable than LIBOR. We intend to monitor the developments with respect to the potential phasing out of LIBOR after 2021 and will work with BBVA USA to ensure any transition away from LIBOR will have minimal impact on our financial condition. We, however, can provide no assurances regarding the impact of the discontinuation of LIBOR on the interest rate that we would be required to pay or on our financial condition. PPP Loan As a result of the uncertainty surrounding the COVID-19 pandemic and its impact on our operating results, we applied for and, on May 5, 2020, we received loan proceeds of $1.4 million under the Paycheck Protection Program (“PPP”) under a promissory note from BMO Harris Bank National Association (the “PPP Loan”). The PPP was established as part of the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) and is administered by the U.S. Small Business Administration (“SBA”). The PPP Loan has a two-year term and bears interest at an annual interest rate of 1%. Monthly principal and interest payments are deferred for six months, and the maturity date is April 30, 2022. We used the $1.4 million of loan proceeds to fund eligible payroll, rent and utility expenses under the terms of the PPP Loan. As a result, we met the PPP eligibility criteria for forgiveness and have concluded that the PPP Loan represents, in substance, funds provided under a government grant. We received confirmation from BMO Harris Bank of the full loan forgiveness and repayment by the SBA effective December 28, 2020. As such, in accordance with IAS 20 “Accounting for Government Grants and Disclosure of Government Assistance,” we have recognized the use of $1.4 million of the loan proceeds as of December 31, 2020 as Other Income. Monroe Term Loan On October 19, 2020, QRHC and certain of its domestic subsidiaries entered into a Credit Agreement (the “Credit Agreement”) , dated as of October 19, 2020, with Monroe Capital, as administrative agent for the lenders thereto • A senior secured term loan facility in the principal amount of $11.5 million. The senior secured term loan at the LIBOR Rate for LIBOR Loans plus the Applicable Margin; provided, that if the provision of LIBOR Loans becomes unlawful or unavailable, then interest will be payable at a rate per annum equal to the Base Rate from time to time in effect plus the Applicable Margin for Base Rate Loans. The maturity date of the term loan facility is October 19, 2025 (the "Maturity Date"). The senior secured term loan will amortize in aggregate annual amounts equal to 1.00% of the original principal amount of the senior secured term loan facility with the balance payable on the Maturity Date. Proceeds of the senior secured term loan were permitted to be used in connection with the acquisition. • A delayed draw term loan facility in the maximum principal amount of $12.5 million. Loans under the delayed draw term loan facility may be requested at any time until October 19, 2021. Pricing and maturity for the outstanding principal amount of the delayed draw term loan shall be the same as for the senior secured term loan. Proceeds of the delayed draw term loan are to be used for Permitted Acquisitions (as defined in the Credit Agreement). • An accordion term loan facility in the maximum principal amount of $40.0 million. Loans under the accordion loan facility may be requested at any time until the Maturity Date. Each accordion term loan shall be on the same terms as those applicable to the senior secured term loan. Proceeds of accordion term loans are permitted to be used for Permitted Acquisitions. Certain of QRHC’s domestic subsidiaries are the borrowers under the Credit Agreement. QRHC is the guarantor under the Credit Agreement. As security for the obligations of the borrowers under the Credit Agreement, (i) the borrowers under the Credit Agreement have granted a first priority lien on substantially all of their tangible and intangible personal property, including a pledge of the capital stock and membership interests, as applicable, of certain of QRHC’s direct and indirect subsidiaries, and (ii) the guarantors under the Credit Agreement have granted a first priority lien on the capital stock and membership interests, as applicable, of QRHC’s direct and indirect domestic subsidiaries. The Credit Agreement contains certain financial covenants, including a minimum fixed charge coverage ratio and a senior net leverage ratio. In addition, the Credit Agreement contains negative covenants limiting, among other things, additional indebtedness, transactions with affiliates, additional liens, sales of assets, dividends, investments and advances, prepayments of debt, mergers and acquisitions, and other matters customarily restricted in such agreements. The Credit Agreement also contains customary events of default, including payment defaults, breaches of representations and warranties, covenant defaults, events of bankruptcy and insolvency, change of control, and failure of any guaranty or security document supporting the Credit Agreement to be in full force and effect. Upon the occurrence of an event of default, the outstanding obligations under the Credit Agreement may be accelerated and become immediately due and payable. At the same time as the borrowing of the $11.5 million under the Credit Agreement, in a separate agreement, we issued Monroe Capital a warrant to purchase 500,000 shares of QRHC’s common stock exercisable immediately. For the $12.5 million delayed draw term loan facility, we will issue a separate warrant to purchase 350,000 shares upon drawing on this facility or on October 19, 2021, whichever occurs first, or upon certain other events. Both warrants have an exercise price of $1.50 per share and an expiration date of March 19, 2028. We estimated the value of the 500,000-share warrant issued using the Black Scholes option pricing model and recorded a debt discount of approximately $766,000 which will be amortized over the term of the Credit Agreement. We also executed a letter agreement that provides that the warrant holder will receive minimum net proceeds of $1 million less any net proceeds received from the sale of the warrant shares, which is conditional on the full exercise and sale of all the warrant shares at the same time and upon a date two years after the closing date of the agreement. Green Remedies Promissory Note On October 19, 2020, we issued an unsecured subordinated promissory note to the seller of Green Remedies in the aggregate principal amount of $2,684,250, payable commencing on January 1, 2021 in quarterly installments through October 1, 2025 and subject to an interest rate of 3.0% per annum.

The non-current portion of deferred consideration payable to the seller is payable in either cash or shares of our common stock. The earn-out is not to exceed $2,250,000 over an earn-out period, as defined in the Asset Purchase Agreement. We valued the earn-out liability at $440,000 using a Monte Carlo simulation.

Lessee Disclosure [Abstract]
Leases	8. Leases We lease corporate office space in The Colony, Texas under an 84-month, non-cancelable operating lease. Upon the adoption of ASC 842 on January 1, 2019, we recorded approximately $2.0 million and $2.2 million to record the operating lease right-of-use asset and the related liabilities, respectively. The lease expires in October 2022. Our office lease has a remaining term of 1.75 years as of December 31, 2020, and we used an effective interest rate of 2.456%, which was our incremental borrowing rate in effect at the inception of the lease as our lease does not provide a readily determinable implicit rate. In connection with our acquisition of the assets of Green Remedies, we entered into a lease for office space in Burlington, NC. We recorded a right of use asset associated with this lease of approximately $80,000. The lease expires in October 2023. This office lease had a remaining term of 2.8 years as of December 31, 2020, and we used an effective interest rate of 9.50%, which was our incremental borrowing rate in effect at the inception of the lease as our lease does not provide a readily determinable implicit rate. This lease may be terminated under certain conditions as defined in the lease agreement. The lessor is a related party that is owned by the seller of Green Remedies and is employed by us. The future minimum lease payments required under our office leases as of December 31, 2020 are as follows: Year Ending December 31, Amount 2021 $ 694,800 2022 528,750 2023 24,513 Total lease payments 1,248,063 Less: Interest (36,480 ) Present value of lease payments 1,211,583 We leased certain equipment to a customer under a lease arrangement that expired in 2020. The capital lease receivable amounts are approximately $5,000 at December 31, 2019, which was included in Prepaid expenses and other current assets. Balance Sheet Classification The table below presents the lease related assets and liabilities recorded on the balance sheet. Right-of-use assets and related liabilities related to finance leases at December 31, 2020 are de minimis. As of December 31, 2020 2019 Operating Leases Right-of-use operating lease assets: Property and equipment, net and other assets $ 1,103,761 $ 1,595,044 Lease Liabilities: Accounts payable and accrued liabilities $ 668,019 $ 627,896 Other long-term liabilities 543,564 1,136,583 Total operating lease liabilities $ 1,211,583 $ 1,764,479 Lease Costs For the years ended December 31, 2020 and 2019, we recorded $608,674 and $602,587, respectively, of fixed cost operating lease expense. Our operating lease expense is offset by a minimum annual incentive received from a local Economic Development Council, which is accrued monthly and will continue over the term of the lease through August 2022. This minimum annual incentive is $63,000, which increased to $93,600 for the annual incentive period starting September 2020 through the remainder of the lease term. Effective December 1, 2019, we subleased a portion of our corporate office space to a single tenant. The sublease agreement is accounted for as an operating lease and we recognize sublease income as an offset to operating lease expense on a straight-line basis over the term of the sublease agreement through August 2022. Sublease income, net of amortized leasing costs, for the year ended December 31, 2020 and 2019 was approximately $49,000 and $4,000, respectively. Cash paid for operating leases approximated operating lease expense and non-cash right of use asset amortization for the years ended December 31, 2020 and 2019.

Revenue From Contract With Customer [Abstract]
Revenue	9. Revenue Operating Revenues We provide businesses with services to reuse, recycle, and dispose of a wide variety of waste streams and recyclables generated by their operations. Service revenues are primarily generated from fees charged for our collection, transfer, disposal and recycling services and from sales of commodities by our recycling operations. In addition, we have product sales and other revenue primarily from sales of products such as antifreeze and windshield washer fluid, as well as minor ancillary services. Revenue Recognition We recognize revenue as services are performed or products are delivered. For example, we recognize revenue as waste and recyclable material are collected or when products are delivered. We recognize revenue net of any contracted pricing discounts or rebate arrangements. We generally recognize revenue for the gross amount of consideration received as we are generally the primary obligor (or principal) in our contracts with customers as we hold complete responsibility to the customer for contract fulfillment. We record amounts collected from customers for sales tax on a net basis. Disaggregation of Revenue The following table presents our revenue disaggregated by source. Three customers accounted for 51% of revenue for the year ended December 31, 2020, and three customers accounted for 53% of revenue for the year ended December 31, 2019. We operate primarily in the United States, with minor services in Canada.

We classify our contract acquisition costs as current or noncurrent based on the timing of when we expect to recognize the amortization and are included in other assets. As of December 31, 2020 and 2019 we had $100,000 and $113,750, respectively, of deferred contract costs. During the year ended December 31, 2020, we amortized $203,750 deferred contract costs to selling, general, and administrative expense. During the year ended December 31, 2019, we amortized $215,000 deferred contract costs to selling, general, and administrative expense. Certain customers are billed in advance, and, accordingly, recognition of related revenues is deferred as a contract liability until the services are provided and control transferred to the customer. As of December 31, 2020 and 2019, we had $50,454 and $19,644, respectively, of deferred revenue, which was classified in “Other current liabilities.”

Income Taxes	10. Income Taxes We compute income taxes using the asset and liability method in accordance with FASB ASC Topic 740, Income Taxes The components of net deferred taxes are as follows: As of December 31, 2020 2019 Deferred tax assets (liabilities): Net operating loss $ 3,961,000 $ 4,616,000 Depreciation and amortization 4,829,000 5,002,000 Stock-based compensation 3,442,000 3,113,000 Capitalized software costs (237,000 ) (561,000 ) Bonus accrual 221,000 — Allowance for doubtful accounts 255,000 206,000 Other 62,000 76,000 Total deferred tax assets, net 12,533,000 12,452,000 Less: valuation allowance (12,533,000 ) (12,452,000 ) Net deferred taxes $ — $ — Our statutory income tax rate is expected to be approximately 27%. We had state income tax expense of $254,004 and $219,082 for the years ended December 31, 2020 and 2019, respectively, which is attributable to state obligations for states with no net operating loss carryforwards, and the continued reserve against the benefit of the net operating losses at the federal level. The provision for income taxes consisted of the following: Years Ended December 31, 2020 2019 Current $ 254,004 $ 219,082 Deferred — — Total $ 254,004 $ 219,082 The reconciliation between the income tax expense calculated by applying statutory rates to net loss and the income tax expense reported in the accompanying consolidated financial statements is as follows: Years Ended December 31, 2020 2019 U.S. federal statutory rate applied to pretax income $ 271,000 $ 34,000 State taxes, net of federal benefit 237,004 165,082 Permanent differences (378,000 ) 11,000 Benefit of federal operating loss carryforwards (411,000 ) (381,000 ) Change in state tax rates and other 454,000 140,000 Change in valuation allowance 81,000 250,000 $ 254,004 $ 219,082 As of December 31, 2020 and 2019, we had federal income tax net operating loss carryforwards of approximately $14,500,000 and $17,200,000, respectively, which expire at various dates ranging from 2032 through 2037. We are subject to limitations existing under Internal Revenue Code Section 382 (Change of Control) relating to the availability of the operating loss. Such limitation of the net operating losses may have occurred, which we have not fully analyzed at this time as we have fully reserved the deferred tax asset. As of December 31, 2020 and 2019, we did not recognize any assets or liabilities relative to uncertain tax positions, nor do we anticipate any significant unrecognized tax benefits will be recorded during 2021. It is our policy to classify interest and penalties on income taxes as interest expense or penalties expense, should any be incurred. Tax positions are positions taken in a previously filed tax return or positions expected to be taken in a future tax return that are reflected in measuring current or deferred income tax assets and liabilities reported in the financial statements. Tax positions include the following: • an allocation or shift of income between taxing jurisdictions; • the characterization of income or a decision to exclude reportable taxable income in a tax return; or • a decision to classify a transaction, entity, or other position in a tax return as tax exempt. We are potentially subject to tax audits for federal and state tax returns for tax years ended 2017 to 2020. Tax audits by their very nature are often complex and can require several years to complete.

Fair Value of Financial Instruments	11. Fair Value of Financial Instruments Our financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, deferred revenue and notes payable. We do not believe that we are exposed to significant interest, currency, or credit risks arising from these financial instruments. The fair values of these financial instruments approximate their carrying values using Level 3 inputs, based on their short maturities or, for notes payable, based on borrowing rates currently available to us for loans with similar terms and maturities.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	12. Commitments and Contingencies Indemnifications During the normal course of business, we make certain indemnities and commitments under which we may be required to make payments in relation to certain transactions. These may include (i) intellectual property indemnities to customers in connection with the use, sales, and/or license of products and services; (ii) indemnities to customers in connection with losses incurred while performing services on their premises; (iii) indemnities to vendors and service providers pertaining to claims based on negligence or willful misconduct; and (iv) indemnities involving the representations and warranties in certain contracts. In addition, under our bylaws we are committed to our directors and officers for providing for payments upon the occurrence of certain prescribed events. The majority of these indemnities and commitments do not provide for any limitation on the maximum potential for future payments that we could be obligated to make. We have not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, we believe the estimated fair value of these agreements is minimal. Accordingly, we had no liabilities recorded for these agreements as of December 31, 2020 and 2019. Defined Contribution Plan We maintain a defined contribution 401(k) plan covering substantially all full-time employees. Employees are permitted to make voluntary contributions, which we match at a certain percentage, to the plan. For the years ended December 31, 2020 and 2019, our plan contribution expense was $184,148 and $182,702, respectively.

Equity [Abstract]
Stockholders' Equity	13. Stockholders’ Equity Preferred Stock Our authorized preferred stock consists of 10,000,000 shares of preferred stock with a par value of $0.001, of which no shares have been issued or were outstanding as of December 31, 2020 and 2019. Preferred stock is to be designated in classes or series and the number of each class or series and the voting powers, designations, preferences, limitations, restrictions, relative rights, and distinguishing designation of each class or series of stock as the Board of Directors shall determine in its sole discretion. Common Stock Our authorized common stock consists of 200,000,000 shares of common stock with a par value of $0.001, of which 18,413,419 and 15,372,905 shares were issued and outstanding as of December 31, 2020 and 2019, respectively. • Equity Offering - On August 5, 2020, QRHC sold 2,950,000 shares of common stock, par value $0.001 per share, at a price of $1.15 per share, pursuant to a registered direct offering (the “Offering”). The gross proceeds of the Offering were $3,392,500, before deducting fees and other estimated offering expenses, and closed on August 7, 2020. The use of the net proceeds from this Offering is intended to finance potential future acquisitions and for general corporate purposes. QRHC’s largest stockholder, which is controlled by the Chairman of the Board, purchased 655,000 shares of our common stock in the Offering at a price of $1.15, subject to the same placement agent discounts and commissions with respect to such shares as purchased by other stockholders in the Offering. Employee Stock Purchase Plan On September 17, 2014, our stockholders approved our 2014 Employee Stock Purchase Plan (“ESPP”). We recorded expense of $36,480 and $31,848 related to the ESPP during the years ended December 31, 2020 and 2019, respectively. During the year ended December 31, 2020, we issued an aggregate 62,398 shares of common stock for $63,149, all to employees under our ESPP, as follows: • On May 14, 2020, we issued 30,206 shares for $30,040 for options that vested and were exercised. • On November 14, 2020, we issued 32,192 shares for $33,109 for options that vested and were exercised. During the year ended December 31, 2019 we issued an aggregate 44,035 shares of common stock for $70,668, all to employees under our ESPP, as follows: • On May 14, 2019, we issued 21,283 shares for $29,669 for options that vested and were exercised. • On November 14, 2019, we issued 22,752 shares for $40,999 for options that vested and were exercised. Warrants The following table summarizes the warrants issued and outstanding as of December 31, 2020: Warrants Issued and Outstanding as of December 31, 2020 Date of Exercise Shares of Description Issuance Expiration Price Common Stock Exercisable warrants 3/30/2016 3/30/2021 $ 3.88 90,431 Exercisable warrants 3/30/2016 3/30/2021 $ 1.15 430,629 Exercisable warrants 10/19/2020 3/19/2028 $ 1.50 500,000 Total warrants issued and outstanding 1,021,060 During the year ended December 31, 2020, we had the following warrant activity: • Certain warrants previously issued on March 30, 2016 to purchase 430,629 shares of our common stock at a price per warrant of $3.88 contain certain anti-dilution provisions, including a down round provision, set forth in the warrants, and therefore, upon the closing of the Offering further described above, the warrant exercise price relating to such warrants was adjusted downward to equal the Offering price of $1.15. The down round provision in these warrants created a deemed dividend to common stockholders of $205,014 for the change in the fair value of the warrants using the Black Scholes pricing model. • As discussed in Note 7, we issued a warrant in connection with a credit agreement to purchase 500,000 shares of QRHC’s common stock exercisable immediately at an exercise price of $1.50 per share and an expiration date of March 19, 2028. • No holders exercised warrants during the year. During the year ended December 31, 2019, we did not issue any warrants and no holders exercised warrants. Incentive Compensation Plan In October 2012, we adopted our 2012 Incentive Compensation Plan (the “2012 Plan”) as the sole plan for providing equity-based incentive compensation to our employees, non-employee directors, and other service providers. The plan allows for the grant of stock options, restricted stock, restricted stock units, stock appreciation rights, performance awards, and other incentive awards to our employees, non-employee directors, and other service providers who are in a position to make a significant contribution to our success and our affiliates. The purpose of the plan is to attract and retain individuals, further align employee and stockholder interests, and closely link compensation with our performance. The plan is administered by the compensation committee of our board of directors. Our policy is to fulfill any exercise of options from common stock that is authorized and unissued. The maximum number of shares of common stock available for grant under the plan is 4,837,500. The number of shares available for award under the plan is subject to adjustment for certain corporate changes in accordance with the provisions of the plan. Stock Options The following table summarizes the stock option activity from January 1, 2019 through December 31, 2020: Stock Options Weighted- Exercise Average Number Price Per Exercise Price of Shares Share Per Share Outstanding at January 1, 2019 1,773,066 $1.17 — $26.00 $ 7.02 Granted 1,074,515 $1.51 — $3.12 $ 1.93 Canceled/Forfeited (402,128 ) $1.51 — $26.00 $ 15.64 Outstanding at December 31, 2019 2,445,453 $1.17 — $23.20 $ 3.37 Granted 998,713 $1.35 — $2.32 $ 1.56 Canceled/Forfeited (266,224 ) $1.48 — $16.80 $ 3.55 Outstanding at December 31, 2020 3,177,942 $1.17 — $23.20 $ 2.78 The weighted-average grant-date fair value of options granted was $1.01 and $1.23 for the years ended December 31, 2020 and 2019, respectively. For the years ended December 31, 2020 and 2019, the intrinsic value of options outstanding was approximately $1,149,021 and $360,573, respectively, and the intrinsic value of options exercisable was approximately $432,248 and $53,259, respectively. The following additional information applies to options outstanding at December 31, 2020: Range of Exercise Prices Outstanding at December 31, 2020 Weighted- Average Remaining Contractual Life Weighted- Average Exercise Price Exercisable at December 31, 2020 Weighted- Average Exercise Price $1.17 - $23.20 3,177,942 7.4 $ 2.78 1,877,392 $ 3.40 The following additional information applies to options outstanding at December 31, 2019: Range of Exercise Prices Outstanding at December 31, 2019 Weighted- Average Remaining Contractual Life Weighted- Average Exercise Price Exercisable at December 31, 2019 Weighted- Average Exercise Price $1.17 - $23.20 2,445,453 7.6 $ 3.37 1,209,087 $ 4.47 Stock-based compensation expense for stock-based incentive awards was $1,171,885 and $1,019,409 for the years ended December 31, 2020 and 2019, respectively. At December 31, 2020, the balance of unearned stock-based compensation to be expensed in future periods related to unvested share-based awards was approximately $1.0 million. The weighted-average period over which the unearned stock-based compensation is expected to be recognized is approximately 2 years. Stock-Based Compensation We account for all stock-based payment awards made to employees and directors, including stock options and employee stock purchases, based on estimated fair values. We estimate the fair value of share-based payment awards on the date of grant using an option-pricing model and the value of the portion of the award is recognized as expense over the requisite service period. We recognize the effects of forfeitures in compensation cost when they occur. We use the Black-Scholes-Merton option-pricing model as our method of valuation. The fair value is amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. The fair value of share-based payment awards on the date of grant as determined by the Black-Scholes-Merton model is affected by our stock price as well as other assumptions. These assumptions include the expected stock price volatility over the term of the awards, and the actual and projected employee stock option exercise behaviors. The weighted-average estimated value of employee stock options granted during the years ended December 31, 2020 and 2019 were estimated using the Black-Scholes-Merton option pricing model with the following weighted-average assumptions: Years Ended December 31, 2020 2019 Expected volatility 75 % 76 % Risk-free interest rate 0.49 % 2.37 % Expected dividends 0.00 % 0.00 % Expected term in years 5.7 5.8 Deferred Stock Units – During the year ended December 31, 2020, we granted 47,212 During the year ended December 31, 2019, we granted 14,451 DSUs and recorded director compensation expense of $34,649 related to the grants. We had 73,231 and 14,451 DSUs outstanding at December 31, 2020 and 2019, respectively.

Earnings Per Share [Abstract]
Net Income (Loss) per Share	14. Net Income (Loss) per Share We compute basic net income (loss) per share using the weighted average number of shares of common stock outstanding plus the number of common stock equivalents for DSUs during the period. We compute diluted net income (loss) per share using the weighted average number of shares of common stock outstanding during the period, adjusted for the dilutive effect of common stock equivalents. In periods where losses are reported, the weighted average number of shares of common stock outstanding excludes common stock equivalents because their inclusion would be anti-dilutive. Dilutive potential common shares consist of the incremental common shares issuable upon the exercise of outstanding stock options. Dilutive potential securities are excluded from the computation of earnings per share if their effect is antidilutive. The dilutive effect of outstanding stock options and warrants is reflected in diluted earnings per share by application of the treasury stock method. The computation of basic and diluted net income (loss) per share attributable to common stockholders is as follows: Years Ended December 31, 2020 2019 Numerator: Net income (loss) $ 1,034,369 $ (55,240 ) Deemed dividend for warrant down round provision (205,014 ) — Net income (loss) applicable to common stockholders 829,355 (55,240 ) Denominator: Weighted average common shares outstanding, basic 16,661,472 15,347,039 Effect of dilutive common shares 94,088 — Weighted average common shares outstanding, diluted 16,755,560 15,347,039 Net income (loss) per share: Basic $ 0.05 $ (0.00 ) Diluted $ 0.05 $ (0.00 ) Anti-dilutive securities excluded from diluted net income (loss) per share: Stock options 1,939,525 2,445,453 Warrants 90,431 521,060 Total anti-dilutive securities excluded from net income (loss) per share 2,029,956 2,966,513

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Principles of Presentation and Consolidation	Principles of Presentation and Consolidation The consolidated financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The accompanying consolidated financial statements include the operating activity of QRHC and its subsidiaries for the years ended December 31, 2020 and 2019. As QRHC, Quest, LDI, Youchange, QVC, QV One, and QSS each operate as environmental-based service companies, we did not deem segment reporting necessary.
Accounting Estimates	Accounting Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could materially differ from those estimates. We use significant estimates when accounting for the carrying amounts of accounts receivable, goodwill and other intangible assets, stock-based compensation expense, deferred taxes, and the fair value of assets and liabilities acquired in asset acquisitions, all of which are discussed in their respective notes to the consolidated financial statements.
Revenue Recognition	Revenue Recognition We recognize revenue as services are performed or products are delivered. For example, we recognize revenue as waste and recyclable material are collected or when products are delivered. We recognize revenue net of any contracted pricing discounts or rebate arrangements. We generally recognize revenue for the gross amount of consideration received as we are generally the primary obligor (or principal) in our contracts with customers as we hold complete responsibility to the customer for contract fulfillment. We record amounts collected from customers for sales tax on a net basis.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid instruments with a maturity of three months or less when purchased to be cash equivalents.
Accounts Receivable	Accounts Receivable We follow the allowance method of recognizing uncollectible accounts receivable, which recognizes bad debt expense based on a review of the individual accounts outstanding and our prior history of uncollectible accounts receivable. We extend credit based on an evaluation of each customer’s financial condition, and our receivables are generally unsecured. Accounts receivable are stated net of an allowance for doubtful accounts in the consolidated balance sheets. We consider accounts past due if outstanding longer than contractual payment terms. We record an allowance based on consideration of a number of factors, including the length of time trade accounts are past due, our previous loss history, the creditworthiness of individual customers, economic conditions affecting specific customer industries, and economic conditions in general. We charge-off accounts receivable after all reasonable collection efforts have been exhausted. We credit payments subsequently received on such receivables to bad debt expense in the period we receive the payment. As of December 31, 2020 and 2019, we had established an allowance of $935,261 and $767,464, respectively, for potentially uncollectible accounts receivable. We record delinquent finance charges on outstanding accounts receivable only if they are collected. In the year ended December 31, 2020 we recorded a $47,940 increase in our allowance for doubtful accounts related to certain receivables acquired in the Green Remedies acquisition as further described in Note 3. The changes in our allowance for doubtful accounts for the years ended December 31, 2020 and 2019 were as follows: Years ended December 31, 2020 2019 Beginning balance $ 767,464 $ 929,339 Bad debt expense 120,936 60,000 Uncollectible accounts written off, net (1,079 ) (221,875 ) Addition related to acquisition 47,940 — Ending balance $ 935,261 $ 767,464
Fair Value Measurements	Fair Value Measurements ASC Topic 820, Fair Value Measurements Level 1: Quoted prices in active markets for identical assets or liabilities; Level 2: Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3: Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect our own estimate of assumptions that market participants would use in pricing the asset or liability.
Property and Equipment	Property and Equipment We record property and equipment at cost. We provide for depreciation on the straight-line method, over the estimated useful lives of the assets. We amortize leasehold improvements over the shorter of the estimated useful life or the remaining term of the related leases. We charge expenditures for repairs and maintenance to operations as incurred; we capitalize renewals and betterments when they extend the useful life of the asset. We record gains and losses on the disposition of property and equipment in the period incurred. We report assets held for sale, if any, at the lower of the carrying amount or fair value less costs to sell. The useful lives of property and equipment for purposes of computing depreciation are as follows: Vehicles 5 to 7 years Computer equipment 3 to 5 years Office furniture and fixtures 5 to 7 years Machinery and equipment 5 to 7 years Leasehold improvements 5 to 7 years
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets We analyze long-lived assets, including property and equipment and definite-lived intangible assets, which are held and used in our operations, for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. We review the amortization method and estimated period of useful life at least at each balance sheet date. We record the effects of any revision to operations when the change arises. We recognize impairment when the estimated undiscounted cash flow generated by those assets is less than the carrying amounts of such assets. The amount of impairment is the excess of the carrying amount over the fair value of such assets. We did not recognize any impairment charges for long-lived assets during 2020 and 2019.
Goodwill	Goodwill We record as goodwill the excess of (i) the consideration transferred, the amount of any non-controlling interest in the acquiree, and the acquisition date fair value of any previous equity interest in the acquired entity over the (ii) fair value of the net identifiable assets acquired. We do not amortize goodwill; however, annually, or whenever there is an indication that goodwill may be impaired, we evaluate qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. Our test of goodwill impairment includes assessing qualitative factors and the use of judgment in evaluating economic conditions, industry and market conditions, cost factors, and entity-specific events, as well as overall financial performance. We performed our most recent goodwill impairment analysis in the third quarter of 2020, utilizing an income approach with no impairment recorded. We believe that the discounted cash flow method best captures the significant value-creating activities we are undertaking. The primary assumptions in our income approach included estimating cash flows and projections. We determined that the fair value of our goodwill exceeded our carrying value, and consequently, no impairment was deemed to have occurred. However, a prolonged period of declining gross margins or a significant decrease in our anticipated revenue growth could result in the write-off of a portion or all of our goodwill and other intangible assets in future periods.
Net Income (Loss) per Share	Net Income (Loss) per Share We compute basic net income (loss) per share using the weighted average number of shares of common stock outstanding plus the number of common stock equivalents for Deferred Stock Units, or “DSUs”, during the period. We compute diluted net income (loss) per share using the weighted average number of shares of common stock outstanding during the period, adjusted for the dilutive effect of common stock equivalents. Dilutive potential common shares consist of the incremental common shares issuable upon the exercise of outstanding stock options. Dilutive potential securities are excluded from the computation of earnings per share if their effect is antidilutive. The dilutive effect of outstanding stock options and warrants is reflected in diluted earnings per share by application of the treasury stock method.
Concentrations	Concentrations Financial instruments that potentially subject us to credit risk consist principally of cash, cash equivalents, and trade accounts receivable. We deposit our cash with commercial banks. Cash deposits at commercial banks are at risk to the extent that the balances exceed the Federal Deposit Insurance Corporation insured level per institution. The bank cash balances on deposit may periodically exceed federally insured limits, such as $6,875,321 at December 31, 2020; however, we have never experienced any losses related to these balances. We sell our services and products primarily to customers without requiring collateral; however, we routinely assess the financial condition of our customers and maintain allowances for anticipated losses. From year to year, the customers that exceed 10% of our annual revenue, if any, may change. The following table discloses the number of customers that accounted for more than 10% of our annual revenue and their related receivable balances for the years ended December 31, 2020 and 2019: Customers Exceeding 10% of Revenue Year Number of Customers Revenue Combined Percent Accounts Receivable Combined Percent 2020 3 51 % 27 % 2019 3 53 % 36 % We believe we have no significant credit risk in excess of recorded reserves.
Leases	Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets and current and long-term operating lease liabilities on our consolidated balance sheets. We currently do not have any material finance lease arrangements. Operating lease ROU assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate in effect at the commencement date of the lease in determining the present value of future payments. When we have the option to extend the lease term, terminate the lease before the contractual expiration date, or purchase the leased asset, and if it is reasonably certain that we will exercise the option, we consider these options in determining the classification and measurement of the lease. Leases with an initial term of 12 months or less are not recorded on the balance sheet.
Income Taxes	Income Taxes We recognize deferred tax assets and liabilities for the future tax consequences of temporary differences between the book and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. We establish valuation allowances to reduce a deferred tax asset to the amount expected to be realized. We assess our ability to realize deferred tax assets based on current earnings performance and on projections of future taxable income in the relevant tax jurisdictions. These projections do not include taxable income from the reversal of deferred tax liabilities and do not reflect a general growth assumption but do consider known or pending events, such as the passage of legislation. We review our estimates of future taxable income annually. We first analyze all tax positions to determine if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of any related appeals or litigation processes. After the initial analysis, we measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Our income tax returns are subject to adjustment under audit for approximately the last three years. If we are required to pay interest on the underpayment of income taxes, we recognize interest expense in the first period the interest becomes due according to the provisions of the relevant tax law. If we are subject to payment of penalties, we recognize an expense for the amount of the statutory penalty in the period when the position is taken on the income tax return. If we did not recognize the penalty in the period when the position was initially taken, we recognize the expense in the period when we change our judgment about meeting minimum statutory thresholds related to the initial position taken.
Advertising	Advertising We charge our advertising costs to expense when incurred. During the years ended December 31, 2020 and 2019, advertising expense totaled $51,247 and $20,364, respectively.
Stock-Based Compensation	Stock-Based Compensation We measure all share-based payments, including grants of options to purchase common stock and the issuance of deferred stock units to employees, third parties and board members, using a fair value-based method, in accordance with ASC Topic 718, Stock Compensation We estimate the fair value of stock options using the Black-Scholes-Merton valuation model. Significant assumptions used in the calculation are as follows: • We determine the expected term in accordance with SEC Staff Accounting Bulletin No. 107 using the simplified method for plain vanilla options by the average of the contractual term and vesting period of the award as appropriate statistical data required to properly estimate the expected term was not available; • We measure the expected volatility using the historical changes in the market price of our common stock; • We use the implied yield on zero-coupon U.S. Treasury bonds with a remaining maturity equal to the expected term of the awards to approximate the risk-free interest rate; and • We recognize the effects of forfeitures in compensation cost when they occur.
Deferred Stock Units	Deferred Stock Units Effective September 1, 2019, nonemployee directors can elect to receive all or a portion of their annual retainers in the form of DSUs. The DSUs are recognized at their fair value on the date of grant. Director fees deferred into stock units are calculated and expensed each month by taking fees earned during the month and dividing by the closing price of our common stock on the last trading day of the month, rounded down to the nearest whole share. Each DSU represents the right to receive one share of our common stock following the completion of a director’s service.
Business Combinations	Business Combinations Our acquisition of the assets of Green Remedies was accounted for in accordance with ASC Topic 805, Business Combinations. In purchase accounting, identifiable assets acquired and liabilities assumed are recognized at their estimated fair values at the acquisition date, and any remaining purchase price is recorded as goodwill. In determining the fair values of assets acquired and liabilities assumed, we make significant estimates and assumptions, particularly with respect to long-lived tangible and intangible assets. Critical estimates used in valuing tangible and intangible assets include, but are not limited to, future expected cash flows, discount rates, market prices and asset lives. See Note 3 for more information related to our acquisition. Our consolidated financial statements include the results of operations from the date of the acquisition. We expense all acquisition-related costs as incurred in selling, general and administrative expenses in the consolidated statements of operations.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Adopted In July 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-11 Earnings per Share (Topic 260). On January 1, 2020, we adopted ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40) of the hosting arrangement, including periods covered by renewal options that are reasonably certain to be exercised. This guidance also requires entities to present the expense in the same line item in the statement of operations as the fees associated with the hosting arrangement and classify payments for capitalized implementation costs in the statement of cash flows in the same manner as payments made for fees associated with the hosting element. T In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. the London Interbank Offered Rate (“LIBOR”). The amendments are elective and apply to all entities that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The expedients and exceptions provided by the amendments generally do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. As further discussed in Note 7, our ABL Facility provides procedures for determining a replacement or alternative rate in the event that LIBOR is unavailable. As such, we do not expect the transition away from LIBOR to have a material impact on our consolidated financial statements. Pending Adoption In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326) In December 2019, the FASB issued ASU 2019-12, Income Taxes – (Topic 740), which simplifies the accounting for income taxes by removing certain exceptions and amending guidance to improve consistent application of accounting over income taxes. This guidance is effective January 1, 2021 with early adoption permitted. T There have been no other recent accounting pronouncements or changes in accounting pronouncements that have been issued but not yet adopted that are of significance, or potential significance, to us.
