| Fair Value of Financial Instruments                                         | Fair Value of Financial Instruments The Company has financial instruments, including accounts receivable, accounts payable, loan payable, notes payable, and accrued expense. Due to the short term nature of these instruments, DLH estimates that the fair value of all financial instruments at September 30, 2014 and September 30, 2013 does not differ materially from the aggregate carrying values of these financial instruments recorded in the accompanying consolidated balance sheets.  In addition, the Company has historically presented certain common stock warrants and embedded conversion features associated with Convertible Debentures and has accounted for such derivative financial instruments at fair value.  As further described in Note 12, those convertible debentures matured and the common stock warrants were exercised in the three months ended December 31, 2013.In accordance with authoritative guidance the Company categorized its assets and liabilities based on the priority of the inputs to the valuation technique into a three-level fair value hierarchy as set forth below. The three levels of the hierarchy are defined as follows:Level 1-Unadjusted quoted prices in active markets for identical assets or liabilities. The Company currently does not have any Level 1 financial assets or liabilities.Level 2-Observable inputs other than quoted prices included in Level 1. Level 2 inputs include quoted prices for identical assets or liabilities in non-active markets, quoted prices for similar assets or liabilities in active markets, and inputs other than quoted prices that are observable for substantially the full term of the asset or liability. The Company currently does not have any Level 2 financial assets or liabilities.Level 3-Unobservable inputs reflecting management's own assumptions about the input used in pricing the asset or liability.The following table presents the Company's September 30, 2014 and 2013 liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy (all Level 3):   September 30,   2014 2013Liability:  — —      Derivative financial instruments  $— $160 |
