Description of Business and Significant Accounting Policies | Organization RumbleOn, Inc. (the "Company") was incorporated in October 2013 under the laws of the State of Nevada, as Smart Server, Inc. ("Smart Server"). On February 13, 2017, the Company changed its name from Smart Server, Inc. to RumbleOn, Inc. Description of Business In July 2016, Berrard Holdings Limited Partnership ("Berrard Holdings") acquired 99.5% of the common stock of the Company from the principal stockholder. Shortly after the Berrard Holdings common stock purchase, the Company began exploring the development of a capital light e-commerce platform facilitating the ability of both consumers and dealers to Buy-Sell-Trade-Finance pre-owned vehicles in one online location and in April 2017, the Company launched its platform. The Company's goal is to transform the way pre-owned vehicles are bought and sold by providing users with the most efficient, timely and transparent transaction experience. While the Company's initial customer facing emphasis through most of 2018 was on motorcycles and other powersports, the Company continues to enhance its platform to accommodate nearly any VIN-specific vehicle including motorcycles, ATVs, boats, RVs, cars and trucks, and via its acquisition of Wholesale, Inc. in October 2018, the Company is making a concerted effort to grow its cars and light truck categories. On October 26, 2018, the Company entered into an Agreement and Plan of Merger (as amended, the "Merger Agreement") with the Company's newly-formed acquisition subsidiary RMBL Tennessee, LLC, a Delaware limited liability company ("Merger Sub"), Wholesale Holdings, Inc., a Tennessee corporation ("Holdings"), Wholesale, LLC, a Tennessee limited liability company ("Wholesale"), Steven Brewster and Janelle Brewster (each a "Stockholder," and together the "Stockholders"), Steven Brewster, a Tennessee resident, as the representative of each Stockholder (the "Representative"), and Marshall Chesrown and Steven R. Berrard, providing for the merger of Holdings with and into Merger Sub, with Merger Sub surviving the merger as a wholly-owned subsidiary of the Company (the "Wholesale Transaction"). On October 29, 2018, the Company entered into an Amendment to the Merger Agreement making a technical correction to the definition of "Parent Consideration Shares" contained in the Merger Agreement. Also, on October 26, 2018, the Company entered into a Membership Interest Purchase Agreement (the "Purchase Agreement"), by and among the Company, Steven Brewster and Justin Becker (together the "Express Sellers"), and Steven Brewster as representative of the Express Sellers, pursuant to which the Company acquired all of the membership interests (the "Express Transaction," and together with the Wholesale Transaction, the "Transactions") in Wholesale Express, LLC, a Tennessee limited liability company. The Transactions were both completed on October 30, 2018 (the "Acquisition Date"). As consideration for the Wholesale Transaction, the Company (i) paid cash consideration of $12,353,941, subject to certain customary post-closing adjustments, and (ii) issued to the Stockholders 1,317,329 shares (the "Stock Consideration") of the Company's Series B Non-Voting Convertible Preferred Stock, par value $0.001 (the "Series B Preferred"). As consideration for the Express Transaction, the Company paid cash consideration of $4,000,000, subject to certain customary post-closing adjustments. Wholesale Inc. is one of the largest independent distributors of pre-owned vehicles in the United States and Wholesale Express, LLC is a related logistics company. On February 3, 2019, the Company completed the acquisition (the "Autosport Acquisition") of all of the equity interests of Autosport USA, Inc. ("Autosport"), an independent pre-owned vehicle distributor, pursuant to a Stock Purchase Agreement, dated February 1, 2019 (the "Stock Purchase Agreement"), by and among RMBL Express, LLC (the "Buyer"), a wholly owned subsidiary of Company, Scott Bennie (the "Seller") and Autosport. Aggregate consideration for the Autosport Acquisition consisted of (i) a closing cash payment of $600,000, plus (ii) a fifteen-month $500,000 promissory note (the "Promissory Note") in favor of the Seller, plus (iii) a three-year $1,536,000 convertible promissory note (the "Convertible Note") in favor of the Seller, plus (iv) contingent earn-out payments payable in the form of cash and/or the Company's Class B Common Stock (the "Earn-Out Shares") for up to an additional $787,500 if Autosport achieves certain performance thresholds. In connection with the Autosport Acquisition, the Buyer also paid outstanding debt of Autosport of $235,000 and assumed additional debt of $257,933 pursuant to a promissory note payable to Seller (the "Second Convertible Note"). Serving both consumers and dealers, through its online marketplace platform, the Company makes cash offers for the purchase of pre-owned vehicles. In addition, the Company offers a large inventory of pre-owned vehicles for sale along with third-party financing and associated products. The Company's operations are designed to be scalable by working through an infrastructure and capital light model that is achievable by virtue of a synergistic relationship with its regional partners, which are primarily auctions. The Company utilizes regional partners in the acquisition of pre-owned vehicles to provide inspection, reconditioning and distribution services. These regional partners earn incremental revenue and enhance profitability through fees from inspection, reconditioning and distribution programs. Our business model is driven by our proprietary technology platform. Our initial platform was acquired in February 2017, through our acquisition of substantially all of the assets of NextGen Dealer Solutions, LLC ("NextGen"). Since that time, we have expanded the functionality of that platform through a significant number of high-quality technology development projects and initiatives. Included in these new technology development projects and initiatives were modules or significant upgrades to the existing platforms for: (i) Retail online auction; (ii) native IOS and Android apps; (iii) new architecture on website design and functionality; (iv) RumbleOn Marketplace; (v) redesigned cash offer tool; (vi) deal-jacket tracking tool; (vii) inventory tracking tool; (viii) CRM and multiple third-party integrations; (ix) new analytics and machine learning initiatives; and (x) IT monitoring infrastructure. Basis of Presentation The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with United States generally accepted accounting principles ("GAAP") for interim financial information and in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (the "SEC") and therefore do not contain all of the information and footnotes required by GAAP and the SEC for annual financial statements. The Company's Condensed Consolidated Financial Statements reflect all adjustments (consisting only of normal recurring adjustments) that management believes are necessary for the fair presentation of their financial condition, results of operations, and cash flows for the periods presented. The information at December 31, 2018 in the Company's Condensed Consolidated Balance Sheets included in this quarterly report was derived from the audited Consolidated Balance Sheets included in the Company's 2018 Annual Report on Form 10-K filed with the SEC on April 1, 2019. The Company's 2018 Annual Report on Form 10-K, together with the information incorporated by reference into such report, is referred to in this quarterly report as the "2018 Annual Report." This quarterly report should be read in conjunction with the 2018 Annual Report. Use of Estimates The preparation of these condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. Certain accounting estimates involve significant judgments, assumptions and estimates by management that have a material impact on the carrying value of certain assets and liabilities, disclosures of contingent assets and liabilities and the reported amounts of revenue and expenses during the reporting period, which management considers to be critical accounting estimates. The judgments, assumptions and estimates used by management are based on historical experience, management's experience and other factors, which are believed to be reasonable under the circumstances. Because of the nature of the judgments and assumptions made by management, actual results could differ materially from these judgments and estimates, which could have a material impact on the carrying values of the Company's assets and liabilities and the results of operations. Earnings (Loss) Per Share The Company follows the FASB Accounting Standards Codification ("ASC") Topic 260- Earnings per share Revenue Recognition Revenue for our vehicle distribution segment is derived primarily from our online marketplace and auctions which primarily include: (i) the sale of pre-owned vehicles to consumer and dealers; (ii) vehicle financing; and (iii) vehicle service contracts. Revenue from our vehicle logistics and transportation service segment is derived by providing automotive transportation services between dealerships and auctions throughout the United States. We adopted ASC 606, Revenue from Contracts with Customers For vehicles sold at wholesale to dealers we satisfy our performance obligation for vehicles sales when the wholesale purchaser obtains control of the underlying vehicle, which is upon delivery when the transfer of title, risks and rewards of ownership and control pass to the dealer. We recognize revenue at the amount we expect to receive for the used vehicle, which is the fixed price determined at the auction. The purchase price of the wholesale vehicle is typically due and collected within 30 days of delivery of the wholesale vehicle. For vehicles sold to consumers the purchase price is set forth in the customer contracts at a stand-alone selling price which is agreed upon prior to delivery. We satisfy our performance obligation for used vehicle sales upon delivery when the transfer of title, risks and rewards of ownership and control pass to the customer. We recognize revenue at the agreed upon purchase price stated in the contract, including any delivery charges, less an estimate for returns. Our return policy allows customers to initiate a return during the first three days after delivery. Estimates for returns are based on an analysis of historical experience, trends and sales data. Changes in these estimates are reflected as an adjustment to revenue in the period identified. The amount of consideration received for used vehicle sales to consumers includes noncash consideration representing the value of trade-in vehicles, if applicable, as stated in the contract. Prior to the delivery of the vehicle, the payment is received, or financing has been arranged. Payments from customers that finance their purchases with third parties are typically due and collected within 30 days of delivery of the used vehicle. In future periods additional provisions may be necessary due to a variety of factors, including changing customer return patterns due to the maturation of the online vehicle buying market, macro- and micro-economic factors that could influence customer return behavior and future pricing environments. If these factors result in adjustments to sales returns, they could significantly impact our future operating results. Revenue excludes any sales taxes, title and registration fees, and other government fees that are collected from customers. Vehicle finance fee revenue is recognized upon delivery of the vehicle to the customer, when the sales contract is signed, and the financing has been arranged. We may be charged back for a fee in the event a contract is prepaid, defaulted upon, or terminated. Our risk related to contract cancellations is limited to the commissions that we receive. Cancellations will fluctuate depending on the customer financing default or prepayment rates and shifts in customer behavior. To the extent that actual experience differs from historical trends, there could be adjustments to our finance contract cancellation reserves. Commission revenue on vehicle service contracts is recognized at the time of sale, net of a reserve for estimated contract cancellations. The reserve for cancellations is estimated based on historical experience and recent trends. Our risk related to contract cancellations is limited to the commissions that we receive. Cancellations will fluctuate depending on the customer financing default or prepayment rates, and shifts in customer behavior, including those related to changes in the coverage or term of the product. To the extent that actual experience differs from historical trends, there could be adjustments to our contract cancellation reserves. Vehicle logistics and transportation services revenue is generated primarily by entering into freight brokerage The transaction price is based on the consideration specified in the customer's contract. A performance obligation is created when the customer under a transportation contract submits a bill of lading for the transport of goods from origin to destination. These performance obligations are satisfied as the shipments move from origin to destination. freight brokerage Performance obligations are short-term, with transit days less than one week. Generally, customers are billed either upon shipment of the vehicle or on a monthly basis, and remit payment according to approved payment terms, generally not to exceed 30 days. Purchase Accounting for Business Combinations The Company accounts for acquisitions by allocating the fair value of the consideration transferred to the fair value of the assets acquired and liabilities assumed on the date of the acquisition and any remaining difference is recorded as goodwill. Adjustments may be made to the preliminary purchase price allocation when facts and circumstances that existed on the date of the acquisition surface during the allocation period subsequent to the preliminary purchase price allocation, not to exceed one year from the date of acquisition. Contingent consideration is recorded at fair value based on the facts and circumstances on the date of the acquisition and any subsequent changes in the fair value are recorded through earnings each reporting period. Goodwill Goodwill represents the excess purchase price over the fair value of net assets acquired which is not allocable to separately identifiable intangible assets. Other identifiable intangible assets, such as domain names, are separately recognized if the intangible asset is obtained through contractual or other legal right or if the intangible asset can be sold, transferred, licensed or exchanged. Goodwill is not amortized but tested for impairment at least annually, and more frequently if events or circumstances indicate the carrying amount of the reporting unit more likely than not exceeds fair value. We have the option to qualitatively or quantitatively assess goodwill for impairment and we evaluated our goodwill using a qualitative assessment process. Goodwill is tested for impairment at the reporting unit level. We test our goodwill for impairment in December of each year. In 2018, we evaluated our goodwill using a qualitative assessment process. If the qualitative factors determine that it is more likely than not that the fair value of the reporting unit exceeds the carrying amount, goodwill is not impaired. If the qualitative assessment determines it is more likely than not the fair value is less than the carrying amount, we would further evaluate for potential impairment. There was no impairment of goodwill as of June 30, 2019. Leases Effective January 1, 2019, the Company adopted ASC 842, Leases ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments under the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The implicit rate within the Company's leases is generally not determinable and therefore the incremental borrowing rate at the lease commencement date is utilized to determine the present value of lease payments. The determination of the incremental borrowing rate requires judgment. Management determines the incremental borrowing rate for each lease using the Company's estimated borrowing rate, adjusted for various factors including level of collateralization, term and currency to align with the terms of the lease. The ROU asset also includes any lease prepayments, offset by lease incentives. Certain of the Company's leases include options to extend or terminate the lease. An option to extend the lease is considered in connection with determining the ROU asset and lease liability when the Company is reasonably certain that the option will be exercised. An option to terminate is considered unless the Company is reasonably certain the option will not be exercised. Long-Lived Assets Property and equipment is reviewed for impairment when events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of assets to be held and used are measured by a comparison of the carrying amount of an asset to the future net cash flows expected to be generated by the asset. If such assets or asset groups are considered to be impaired, the impairment to be recognized will be measured by the amount by which the carrying amount of the assets or asset groups exceeds the related fair values. The Company also performs a periodic assessment of the useful lives assigned to the long-lived assets. Technology Development Costs Technology development costs are accounted for pursuant to ASC 350, Intangibles — Goodwill and Other Vehicle Inventory Vehicle inventory is accounted for pursuant to ASC 330, Inventory Cash and Cash Equivalents The Company considers all cash accounts and all highly liquid short-term investments purchased with an original maturity of three months or less to be cash or cash equivalents. As of June 30, 2019 and December 31, 2018, the Company did not have any investments with maturities greater than three months. Restricted Cash In connection with the execution of the Inventory Financing and Security Agreement (the "Credit Facility") by and among the Company's subsidiary, RMBL Missouri, LLC ("RMBL MO"), Ally Bank ("Ally") and Ally Financial, Inc., dated February 16, 2018 the parties entered into a Credit Balance Agreement, and so long as the Company owes any debt to Ally or until the bank otherwise consents, the Company agrees to maintain a Credit Balance at Ally of 1) at least 10% of the amount of the Company's approved and available credit line under the Credit Facility and 2) no greater than 25% of the total principal amount owed to Ally for inventory financed under the Credit Facility. In connection with the inventory financing contract (the "NextGear Facility"), entered into by the Company, its wholly owned subsidiary RMBL Tennessee, Inc., Wholesale, Inc. and NextGear Capital, Inc. ("NextGear"), dated October 30, 2018, Wholesale, Inc. and NextGear entered into a Reserve Agreement requiring Wholesale, Inc. to pay to NextGear $5.5 million (the "Reserve") to be collateral and security for Wholesale Inc.'s liability under the NextGear Facility as well as any amounts owed by Wholesale, Inc. to NextGear and its affiliates, and each of their respective directors, officers, principals, trustees, partners, shareholders or other holders of any ownership interest, as the case may be, employees, representatives, attorneys and agents. NextGear is not required to pay Wholesale Inc. interest on the Reserve balance. Upon the satisfaction of all obligations and the termination by NextGear of the NextGear Facility, NextGear will return to Wholesale, Inc., upon its written request to NextGear no earlier than ten (10) business days from the date the obligations were indefeasibly paid and satisfied in full and the NextGear Facility and terminated by Lender. Property and Equipment, Net Property and equipment is stated at cost less accumulated depreciation and amortization and consists of capitalized technology development costs, furniture and equipment. Depreciation and amortization is recorded on a straight-line basis over the estimated useful life of the assets. Costs of significant additions, renewals and betterments, are capitalized and depreciated. Maintenance and repairs are charged to expense when incurred. Embedded Conversion Features The Company evaluates embedded conversion features within convertible debt under ASC 815, Derivatives and Hedging Debt with Conversion and Other Options From time to time, the Company has issued convertible notes that have conversion prices that create an embedded beneficial conversion feature pursuant to the guidelines established by the ASC Topic 470-20. The Beneficial Conversion Feature ("BCF") of a convertible security is normally characterized as the convertible portion or feature of certain securities that provide a rate of conversion that is below market value or in-the-money when issued. The Company records a BCF related to the issuance of a convertible security when issued and also records the estimated fair value of any conversion feature issued with those securities. Beneficial conversion features that are contingent upon the occurrence of a future event are recorded when the contingency is resolved. The debt discount is amortized to interest expense over the life of the note using the effective interest method. The Company calculates the fair value of the conversion feature embedded in any convertible security using either a) the Black Scholes valuation model or b) a discount cash flow analysis tested for sensitivity to key Level 3 inputs using Monte Carlo simulation. Debt Issuance Costs Debt issuance costs are accounted for pursuant to FASB Accounting Standards Update ("ASU") 2015-03 , Simplifying the Presentation of Debt Issuance Costs Stock-Based Compensation On June 30, 2017, the Company's shareholders approved a Stock Incentive Plan (the "Plan") under which restricted stock units ("RSUs") and other equity awards may be granted to employees and non-employee members of the Board of Directors. The number of shares of Class B Common Stock authorized for issuance under the Plan is 4,000,000 shares. The Company estimates the fair value of awards granted under the Plan on the date of grant. The fair value of an RSU is based on the average of the high and low market prices of the Company's Class B Common Stock on the date of grant and is recognized as an expense on a straight-line basis over its vesting period; to date, substantially all the RSUs issued vest over a three-year period utilizing the following vesting schedule: (i) 20% on the first anniversary of the grant date; (ii) 30% on the second anniversary of the grant date; and (iii) 50% on the third anniversary of the grant date.
