Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Accounting Policies	Basis of Presentation and Accounting Policies Basis of presentation The consolidated financial statements include the accounts of ADDvantage Technologies Group, Inc. and its subsidiaries, all of which are wholly owned (collectively, the “Company”). Intercompany balances and transactions have been eliminated in consolidation. The Company’s reportable segments are Wireless Infrastructure Services (“Wireless”) and Telecommunications (“Telco”). The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial statements and do not include all the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. However, the information furnished reflects all adjustments, which are, in the opinion of management, necessary in order to make the unaudited consolidated financial statements not misleading. The Company’s business is subject to seasonal variations due to weather in the geographic areas where services are performed, as well as calendar events and national holidays. Therefore, the results of operations for the three months ended December 31, 2020 and 2019, are not necessarily indicative of the results to be expected for the full fiscal year. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2020. Reclassification Certain prior period amounts have been reclassified to conform to current year presentation. These reclassifications had no effect on previously reported results of operations or retained earnings. Recently Issued Accounting Standards In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13: “Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments.” This ASU requires entities to measure all expected credit losses for most financial assets held at the reporting date based on an expected loss model which includes historical experience, current conditions, and reasonable and supportable forecasts. Upon adoption, entities will use forward-looking information to better form their credit loss estimates. This ASU also requires enhanced disclosures to help financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an entity’s portfolio. On November 15, 2019, the FASB delayed the effective date of the standard for companies that qualify under smaller reporting company reporting rules. As amended, the effective date of ASC Topic 326 was delayed until fiscal years beginning after December 15, 2022 for SEC filers that are eligible to be smaller reporting companies under the Securities and Exchange Commission definition. We are currently in the process of evaluating this new standard update.

Accounts Receivable Agreements

Accounts Receivable Agreements	3 Months Ended

Receivables [Abstract]
Accounts Receivable Agreements	Accounts Receivable Agreements The Company’s Wireless segment has entered into various agreements, one agreement with recourse, to sell certain receivables to unrelated third-party financial institutions. For the agreement with recourse, the Company is responsible for collecting payments on the sold receivables from its customers. Under this agreement, the third-party financial institution advances the Company 90% of the sold receivables and establishes a reserve of 10% of the sold receivables until the Company collects the sold receivables. As the Company collects the sold receivables, the third-party financial institution will remit the remaining 10% to the Company. At December 31, 2020, the third-party financial institution has a reserve against the sold receivables of $0.3 million, which is reflected as restricted cash. For the receivables sold under the agreement with recourse, the agreement addresses events and conditions which may obligate the Company to immediately repay the institution the outstanding purchase price of the receivables sold. The total amount of receivables uncollected by the institution was $2 million at December 31, 2020 for which there is a limit of $4.0 million. Although the sale of receivables is with recourse, the Company did not record a recourse obligation at December 31, 2020 as the Company concluded that the sold receivables are collectible. The other agreements without recourse are under programs offered by certain customers in the Wireless segment. For the three months ended December 31, 2020 and 2019, the Company received proceeds from the sold receivables under all of the various agreements of $5.0 million and $7.0 million, respectively, and included the proceeds in net cash used in operating activities in the Consolidated Statements of Cash Flows. The fees associated with selling these receivables ranged from 1.0% to 2.3% of the gross receivables sold for the three months ended December 31, 2020 and 2019. The Company recorded costs of $43 thousand and $0.1 million for the three months ended December 31, 2020 and 2019, respectively, in other expense in the Consolidated Statements of Operations.

Receivables [Abstract]
Promissory Note Receivable	Promissory Note ReceivableDuring the fiscal year ended 2019, the Company completed a sale of its former Cable TV reporting segment to Leveling 8, an entity owned by a member of our board and significant shareholder, David Chymiak. Part of the consideration for the sale was a promissory note bearing interest of 6% received from Mr. Chymiak. Mr. Chymiak personally guaranteed the promissory note due to the Company and pledged certain assets to secure the payment of the promissory note, including substantially all of Mr. Chymiak’s Company common stock. During the quarter ended December 31, 2020, the Company received principal payments totaling $1.5 million, of which approximately $1.0 million was a prepayment. At December 31, 2020, there was $2.3 million outstanding on the promissory note. The remaining promissory note becomes due in a final payment on June 29, 2024. March 10, 2020, the Company entered into a loan agreement with its primary financial lender for $3.5 million to monetize a portion of this promissory note receivable. See Note 7 - Debt for disclosures related to the Company's promissory note payable.

Refurbished and used equipment include factory refurbished, Company refurbished and used products. The Telco segment identified certain inventory that more than likely will not be sold or that the cost will not be recovered when it is processed through its recycling program. Therefore, the Company has a $3.1 million allowance at December 31, 2020 and September 30, 2020.

Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Assets	Intangible Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. The Company groups assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash flows. If the undiscounted future cash flows do not indicate the carrying amount of the asset is recoverable, an impairment charge is measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis or appraisals. Intangible assets with their associated accumulated amortization and impairment at December 31, 2020 and September 30, 2020 are as follows, in thousands: December 31, 2020 Intangible assets: Gross Accumulated Amortization Impairment Net Customer relationships – 10 years $ 8,396 $ (4,061) $ (3,894) $ 441 Trade name – 10 years 2,122 (1,217) — 905 Total intangible assets $ 10,518 $ (5,278) $ (3,894) $ 1,346 September 30, 2020 Intangible assets: Gross Accumulated Impairment Net Customer relationships – 10 years $ 8,396 $ (4,021) $ (3,894) $ 481 Trade name – 10 years 2,122 (1,178) — 944 Non-compete agreements – 3 years 374 (374) — — Total intangible assets $ 10,892 $ (5,573) $ (3,894) $ 1,425

Debt

Debt	3 Months Ended

Debt Disclosure [Abstract]
Debt	Debt Loan Agreement On March 10, 2020, the Company entered into a loan agreement with its primary financial lender for $3.5 million, bearing interest at 6% per annum. The loan was payable in seven semi-annual installments of principal and interest with the first payment occurring June 30, 2020. In connection with the $1.5 million payment received in the first fiscal quarter of 2021 from the promissory note receivable, the Company fully repaid the remaining $1.2 million of principal outstanding under this loan. Credit Agreement The Company has a $4.0 million revolving line of credit agreement with its primary financial lender, which matures on December 17, 2021. The line of credit requires quarterly interest payments based on the prevailing Wall Street Journal Prime Rate, floating (3.25% at December 31, 2020), with the addition of a 4% floor rate and a fixed charge coverage ratio of 1.25 to be tested quarterly beginning June 30, 2021. At December 31, 2020, there was $2.8 million outstanding under the line of credit. Future borrowings under the line of credit are limited to the lesser of $4.0 million or the sum of 80% of eligible accounts receivable and 60% of eligible Telco segment inventory. Under these limitations, the Company’s total line of credit borrowing capacity was $4.0 million at December 31, 2020. Loan Covenant with Primary Financial Lender The credit agreement provides that the Company maintain a fixed charge coverage ratio (net cash flow to total fixed charge) of not less than 1.25 to 1.0 to be tested quarterly beginning June 30, 2021. The Company believes that it is probable that it will not be in compliance with this covenant as of the measurement date at June 30, 2021. The noncompliance with this covenant would result in an event of default, which if not cured or waived, could result in the lender accelerating the maturity of the Company’s indebtedness or preventing access to additional funds under the line of credit agreement, or requiring prepayment of outstanding indebtedness under the loan agreement or the line of credit agreement. Paycheck Protection Program Loan On April 14, 2020, the Company received a SBA Payroll Protection Program (“PPP”) loan pursuant to the Paycheck Protection Program under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), with its primary lender for $2.9 million. The PPP loan bears interest at 1% per annum, with monthly payments of principal and interest in the amount of $164,045 commencing on November 10, 2020, and matures on April 10, 2022. However, the Company has applied for forgiveness in accordance with the terms in the CARES Act, and our lender has not required repayments while under consideration for forgiveness. The Paycheck Protection Program provides that the PPP loan may be partially or fully forgiven if the funds are used for certain qualifying expenses as described in the CARES Act. The Company has applied for forgiveness of the PPP loan in accordance with the requirements and limitations under the CARES Act, the PPP Flexibility Act and SBA regulations and requirements. Fair Value of Debt The carrying value of the Company’s variable-rate line of credit approximates its fair value since the interest rate fluctuates periodically based on a floating interest rate. The carrying value of the Company’s term debt approximates fair value.

Equity [Abstract]
Equity Distribution Agreement and Sale of Common Stock	Equity Distribution Agreement and Sale of Common Stock On April 24, 2020, the Company entered into an Equity Distribution Agreement with Northland Securities, Inc., as agent (“Northland”), pursuant to which the Company may offer and sell, from time to time, through Northland, shares of the Company’s common stock, par value 0.01 per share, having an aggregate offering price of up to $13,850,000 ("Shares"). The offer and sale of the Shares will be made pursuant to a shelf registration statement on Form S-3 and the related prospectus filed by the Company with the Securities and Exchange Commission (the “SEC”) on March 3, 2020, as amended on March 23, 2020, and declared effective by the SEC on April 1, 2020. Pursuant to the Sales Agreement, Northland may sell the Shares by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415 of the Securities Act of 1933 (the “Securities Act”), including sales made by means of ordinary brokers’ transactions, including on The Nasdaq Global Market, at market prices or as otherwise agreed with Northland. Northland will use commercially reasonable efforts consistent with its normal trading and sales practices to sell the Shares from time to time, based upon instructions from the Company, including any price or size limits or other customary parameters or conditions the Company may impose. The Sales Agreement may be terminated without prior notice at any time prior to the fulfillment if additional sales are deemed not warranted. The Company will pay Northland a commission rate equal to an aggregate of 3.0% of the aggregate gross proceeds from each sale of Shares and have agreed to provide Northland with customary indemnification and contribution rights. The Company will also reimburse Northland for certain specified expenses in connection with entering into the Sales Agreement. The Sales Agreement contains customary representations and warranties and conditions to the placements of the Shares pursuant thereto.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share are based on the sum of the average number of common shares outstanding and issuable, restricted and deferred shares. Diluted earnings per share include any dilutive effect of stock options and restricted stock. In computing the diluted weighted average shares, the average share price for the period is used in determining the number of shares assumed to be reacquired under the treasury stock method from the exercise of options. Basic and diluted earnings per share for the three months ended December 31, 2020 and 2019 are (in thousands, except per share amounts): Three Months Ended December 31, 2020 2019 Net loss attributable to common shareholders $ (1,953) $ (1,718) Basic and diluted weighted average shares 12,149,778 10,361,292 Basic and diluted loss per common share: $ (0.16) $ (0.17) The table below includes information related to stock options that were outstanding at the end of each respective three-month period ended December 31, but have been excluded from the computation of weighted-average stock options for dilutive securities because their effect would be anti-dilutive. The stock options were anti-dilutive either due to the Company incurring a net loss for the periods presented or the exercise price exceeded the average market price per share of our common stock for the three months ended December 31, 2020 and 2019.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Plan Information The 2015 Incentive Stock Plan (the “Plan”) provides for awards of stock options and restricted stock to officers, directors, key employees and consultants. Under the Plan, option prices will be set by the Compensation Committee and may not be less than the fair market value of the stock on the grant date. At December 31, 2020, 2,100,415 shares of common stock were reserved for stock award grants under the Plan. Of these reserved shares, 483,240 shares were available for future grants. All share-based payments to employees, including grants of employee stock options, are recognized in the consolidated financial statements based on their grant date fair value over the requisite service period. Compensation expense for stock-based awards is included in the operating, selling, general and administrative expense section of the consolidated statements of operations. Stock Options Stock options are valued at the date of the award, which does not precede the approval date, and compensation cost is recognized on a straight-line basis over the vesting period. Stock options granted to employees generally become exercisable over a three A summary of the status of the Company's stock options at December 31, 2020 and changes during the three months then ended is presented below: Shares Wtd. Avg. Aggregate Intrinsic Outstanding at September 30, 2020 100,000 $ 1.55 Granted — — — Exercised — — — Expired — — — Forfeited — — — Outstanding at December 31, 2020 100,000 $ 1.55 $ — Exercisable at December 31, 2020 83,334 $ 1.60 $ — No stock options were granted for the three months ended December 31, 2020. The Company estimates the fair value of the options granted using the Black-Scholes option valuation model. The Company estimates the expected term of options granted based on the historical grants and exercises of the Company’s options, volatility of its common stock at the date of the grant based on both the historical volatility as well as the implied volatility on its common stock, and the risk-free rate is based on the implied yield in effect at the time of the option grant on U.S. Treasury zero-coupon issues with equivalent expected term. The Company has never paid cash dividends on its common stock and does not anticipate paying cash dividends in the future. The Company uses an expected dividend yield of zero. The Company amortizes the resulting fair value of the options ratably over the vesting period of the awards. The Company recognizes forfeitures as they occur. Compensation expense related to unvested stock options recorded for the quarters ended December 31, 2020 and 2019 was $1 thousand and $13.9 thousand respectively.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting The Company is reporting its financial performance based on its external reporting segments: Wireless Infrastructure Services and Telecommunications. These reportable segments are described below. Wireless Infrastructure Services (“Wireless”) The Wireless segment provides turn-key wireless infrastructure services for the four major U.S. wireless carriers, communication tower companies, national integrators, and original equipment manufacturers that support these wireless carriers. These services primarily consist of the installation and upgrade of technology on cell sites and the construction of new small cells for 5G. Telecommunications (“Telco”) The Company’s Telco segment sells new and refurbished telecommunications networking equipment, including both central office and customer premise equipment, to its customer base of telecommunications providers, enterprise customers and resellers located primarily in North America. This segment also offers its customers repair and testing services for telecommunications networking equipment. In addition, this segment offers its customers decommissioning services for surplus and obsolete equipment, which it in turn processes through its recycling program. The Company evaluates performance and allocates its resources based on operating income. The accounting policies of its reportable segments are the same as those described in the summary of significant accounting policies. Segment assets consist primarily of cash and cash equivalents, accounts receivable, inventories, property and equipment, goodwill and intangible assets. The Company changed the allocation of corporate general and administrative expenses between our reportable business segments. At September 30, 2020, the Company did not allocate the corporate general and administrative expenses to the reportable segments and listed those expenses separate from the operating results of those reportable segments. During fiscal 2021, the Company reviewed its reportable segments and its corporate general and administrative expenses and allocation methodology, which resulted in the Company allocating its corporate general and administrative expenses to the reportable segments. The prior period allocations have been adjusted to reflect the Company's current allocation.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presenation	Basis of presentation The consolidated financial statements include the accounts of ADDvantage Technologies Group, Inc. and its subsidiaries, all of which are wholly owned (collectively, the “Company”). Intercompany balances and transactions have been eliminated in consolidation. The Company’s reportable segments are Wireless Infrastructure Services (“Wireless”) and Telecommunications (“Telco”). The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial statements and do not include all the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. However, the information furnished reflects all adjustments, which are, in the opinion of management, necessary in order to make the unaudited consolidated financial statements not misleading. The Company’s business is subject to seasonal variations due to weather in the geographic areas where services are performed, as well as calendar events and national holidays. Therefore, the results of operations for the three months ended December 31, 2020 and 2019, are not necessarily indicative of the results to be expected for the full fiscal year. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2020. Reclassification
Recently issued accounting standards	Recently Issued Accounting Standards In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13: “Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments.” This ASU requires entities to measure all expected credit losses for most financial assets held at the reporting date based on an expected loss model which includes historical experience, current conditions, and reasonable and supportable forecasts. Upon adoption, entities will use forward-looking information to better form their credit loss estimates. This ASU also requires enhanced disclosures to help financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an entity’s portfolio. On November 15, 2019, the FASB delayed the effective date of the standard for companies that qualify under smaller reporting company reporting rules. As amended, the effective date of ASC Topic 326 was delayed until fiscal years beginning after December 15, 2022 for SEC filers that are eligible to be smaller reporting companies under the Securities and Exchange Commission definition. We are currently in the process of evaluating this new standard update.
