Significant Accounting Policies [Text Block]	Note 1 – Summary of Significant Accounting Policies Organization and 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”) as well as an equity-method investment. Intercompany balances and transactions have been eliminated in consolidation. The Company’s reportable segments are Cable Television (“Cable TV”) and Telecommunications (“Telco”). Cash and cash equivalents Cash and cash equivalents includes demand and time deposits, money market funds and other marketable securities with maturities of three Accounts receivable Trade receivables are carried at original invoice amount less an estimate made for doubtful accounts. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions. Trade receivables are written off against the allowance when deemed uncollectible. Recoveries of trade receivables previously written off are recorded when received. The Company generally does not Inventor ies Inventor ies consist of new, refurbished and used electronic components for the Cable TV segment and new, refurbished and used telecommunications equipment for the Telco segment. Inventory is stated at the lower of cost or net realizable value. Cost is determined using the weighted-average method. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. For both the Cable TV and Telco segments, the Company records an inventory reserve provision to reflect inventory at its estimated net realizable value based on a review of inventory quantities on hand, historical sales volumes and technology changes. These reserves are to provide for items that are potentially slow-moving, excess or obsolete. Property and equipment Property and equipment consists of software, office equipment, warehouse and service equipment, and buildings with estimated useful lives generally of 3 5 10 40 $ 0.4 September 30, 2017, 2016 2015.

Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and tax carryforward amounts. Management provides a valuation allowance against deferred tax assets for amounts which are not not” Revenue recognition The Company recognizes revenue for product sales when title transfers, the risks and rewards of ownership have been transferred to the customer, the fee is fixed or determinable and the collection of the related receivable is probable, which is generally at the time of shipment. The stated shipping terms are generally FOB shipping point per the Company's sales agreements with its customers. Accruals are established for expected returns based on historical activity. Revenue for repair services is recognized when the repair is completed and the product is shipped back to the customer. Revenue for recycle services is recognized when title transfers, the risks and rewards of ownership have been transferred to the customer, the fee is fixed or determinable and the collection of the related receivable is probable, which is generally upon acceptance of the shipment at the recycler’s location. Freight Amounts billed to customers for shipping and handling represent revenues earned and are included in sales income in the accompanying consolidated statements of operations. Actual costs for shipping and handling of these sales are included in cost of sales. Advertising costs Advertising costs are expensed as incurred. Advertising expense was $0.5 $0.2 $0.1 September 30, 2017, 2016 2015, Management estimates The preparation of financial statements in conformity with U nited States generally accepted accounting principles requires management 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 differ from those estimates. Any significant, unanticipated changes in product demand, technological developments or continued economic trends affecting the cable or telecommunications industries could have a significant impact on the value of the Company's inventory and operating results. Concentrations of credit risk The Company holds cash with one , which at times exceeds FDIC insured limits. Historically, the Company has not Other financial instruments that potentially subject the Company to concentration of credit risk consist principally of trade receivables. Concentrations of credit risk with respect to trade receivables are limited because a large number of geographically diverse customers make up the Company’s customer base, thus spreading the trade credit risk. The Company controls credit risk through credit approvals, credit limits and monitoring procedures.

The Company determines the fair value of the options issued, using the Black-Scholes valuation model, and amortizes the calculated value over the vesting term of the stock options. Compensation expense for stock-based awards is included in the operating, selling, general and administrative expense section of the consolidated statements of operations. Earnings per share Basic earnings per share is computed by dividing the earnings available to common shareholders by the weighted average number of common shares outstanding for the year. Dilutive earnings per share include any dilutive effect of stock options and restricted stock.

Actual results could differ from those estimates. Any significant, unanticipated changes in product demand, technological developments or continued economic trends affecting the cable or telecommunications industries could have a significant impact on the value of the Company's inventory and operating results.
