Nature of Operations and Summary of Significant Accounting Policies	'
	1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Nature of Operations
	Mitek Systems, Inc. (the “Company”) is a mobile solutions provider engaged in the development, sale and service of its proprietary software solutions related to mobile imaging.
	The Company applies its patented technology in image capture, correction and intelligent data extraction in the mobile financial and business applications markets. The Company’s technology allows users to remotely deposit checks, pay bills, transfer credit card balances, open accounts and get insurance quotes by taking pictures of various documents with their camera-equipped smartphones and tablets instead of using the device keyboard. The Company’s products use advanced algorithms to correct image distortion, extract relevant data, route images to their desired location and process transactions through users’ financial institutions. As of March 31, 2014, the Company has been granted 19 patents and has an additional 23 patent applications pending.
	The Company’s Mobile Deposit® product is software that allows users to remotely deposit a check using their camera-equipped smartphone or tablet. As of March 31, 2014, 2,222 financial institutions have signed agreements to deploy Mobile Deposit® and 1,759 of these financial institutions have deployed Mobile Deposit® to their customers, including all of the top ten U.S. retail banks and more than two-thirds of the top 50 U.S. retail banks and payment processing companies, as ranked by SNL Financial for the fourth quarter of calendar year 2013. Other mobile imaging software solutions the Company offers include Mobile Photo Bill Pay®, a mobile bill payment product that allows users to pay their bills using their bank account and any camera-equipped smartphone or tablet, Mobile Photo Payments™, a product that allows users to pay their bills directly to the biller using their camera-equipped smartphone or tablet, Mobile Balance Transfer™, a product that allows credit card issuers to provide an offer to users and transfer an existing credit card balance by capturing an image of the user’s current credit card statement, Mobile Photo Account Opening™, a product that enables users to open a checking, savings or credit card account by capturing an image of the front and back of their driver’s license with their camera-equipped smartphone or tablet, and Mobile Photo Quoting™, a product that enables users to receive insurance quotes by using their camera-equipped smartphone or tablet to take a picture of their driver’s license and insurance card. The Company’s mobile imaging software solutions can be accessed by any smartphone or tablet using iOS and Android operating systems.
	The Company markets and sells its mobile imaging software solutions through channel partners or directly to enterprise customers that typically purchase licenses based on the number of transactions or subscribers that use the Company’s mobile software. The Company’s mobile imaging software solutions are often embedded in other mobile banking or enterprise applications developed by banks, insurance companies or their partners, and marketed under their own proprietary brands. In February 2014, the Company launched the Mitek Developers Network. The program will extend use of the Company’s Mobile Imaging Platform™ to developers interested in creating new mobile applications using camera-equipped smartphones and tablets.
	Basis of Presentation
	The accompanying unaudited financial statements of the Company as of March 31, 2014 have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and, accordingly, they do not include all information and footnote disclosures required by accounting principles generally accepted in the U.S. (“GAAP”). The Company believes the footnotes and other disclosures made in the financial statements are adequate for a fair presentation of the results of the interim periods presented. The financial statements include all adjustments (solely of a normal recurring nature) which are, in the opinion of management, necessary to make the information presented not misleading. You should read these financial statements and the accompanying notes in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2013, filed with the U.S. Securities and Exchange Commission (the “SEC”) on December 12, 2013 (the “Form 10-K”).
	Results for the three and six months ended March 31, 2014 are not necessarily indicative of results for any other interim period or for a full year.
	Reclassifications
	Certain prior period amounts have been reclassified to conform to the current period presentation. These reclassifications do not impact the reported net loss for such periods and do not have a material impact on the presentation of the overall financial statements.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses and the related disclosure of contingent assets and liabilities. On an ongoing basis, management reviews its estimates based upon currently available information. Actual future results could differ materially from those estimates.
	Net Loss Per Share
	The Company calculates net loss per share in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 260, Earnings Per Share. Basic and diluted net loss per share are based on the weighted-average number of common shares outstanding during the period, without giving effect to potentially dilutive securities. In a period with a net loss position, potentially dilutive securities, such as options, warrants and restricted stock units (“RSUs”), are not included in the calculation of diluted net loss because to do so would be antidilutive, and the number of shares used to calculate basic and diluted net loss is the same.
	For the three and six months ended March 31, 2014 and 2013, the following potentially dilutive common shares were excluded from the calculation of net loss per share, as they would have been antidilutive:
		Three and six months ended
		March 31,
		2014			2013
	Stock options		2,708,063			2,672,758
	Restricted stock units		1,155,472			680,004
	Warrants		6,667			6,667
	Total potentially dilutive common shares outstanding		3,870,202			3,359,429
	The calculation of basic and diluted net loss per share is as follows:
		Three Months Ended						Six Months Ended
		March 31,						March 31,
		2014			2013			2014			2013
	Net loss	$	(2,193,017	)	$	(2,393,275	)	$	(3,661,317	)	$	(3,752,917	)

	Weighted-average common shares and share equivalents outstanding - diluted		30,453,455			26,473,938			30,427,646			26,246,642
	Net loss per share - basic	$	(0.07	)	$	(0.09	)	$	(0.12	)	$	(0.14	)
	Net loss per share - diluted	$	(0.07	)	$	(0.09	)	$	(0.12	)	$	(0.14	)
	Revenue Recognition
	Revenue from sales of software licenses sold through direct and indirect channels is recognized upon shipment of the related product, if the requirements of FASB ASC Topic 985-605, Software Revenue Recognition (“ASC 985-605”) are met, including evidence of an arrangement, delivery, fixed or determinable fee, collectability and vendor specific objective evidence (“VSOE”) of the fair value of the undelivered element. If the requirements of ASC 985-605 are not met at the date of shipment, revenue is not recognized until such elements are known or resolved. Revenue from customer support services, or maintenance revenue, includes post-contract support and the rights to unspecified upgrades and enhancements. VSOE of fair value for customer support services is determined by reference to the price the customer pays for such element when sold separately; that is, the renewal rate offered to customers. Revenue derived from professional services primarily includes consulting, implementation, and training. Revenue from fixed fee service engagements is recognized after the services are performed using the completed performance method. Revenue from time and materials service engagements is generally recognized as the services are performed.
	In those instances when objective and reliable evidence of fair value exists for the undelivered items but not for the delivered items, the residual method is used to allocate the arrangement consideration. Under the residual method, the amount of arrangement consideration allocated to the delivered items equals the total arrangement consideration less the aggregate fair value of the undelivered items. Revenue from post-contract customer support is recognized ratably over the term of the contract. Certain customers have agreements that provide for usage fees above fixed minimums. Fixed minimum transaction fees are recognized as revenue ratably over the term of the arrangement. Usage fees above fixed minimums are recognized as revenue when such amounts are reasonably estimable and billable. Revenue from professional services is recognized when such services are delivered. When a software sales arrangement requires professional services related to significant production, modification or customization of software, or when a customer considers professional services essential to the functionality of the software product, revenue is recognized based on predetermined milestone objectives required to complete the project, as those milestone objectives are deemed to be substantive in relation to the work performed. Any expected losses on contracts in progress are recorded in the period in which the losses become probable and reasonably estimable.
	Accounts Receivable and Allowance for Doubtful Accounts
	Accounts receivable, net, is as follows:
		March 31,			September 30,
		2014			2013
	Accounts receivable	$	3,122,819		$	1,506,627
	Less: Allowance for doubtful accounts		(7,500	)		(12,000	)
	Accounts receivable, net	$	3,115,319		$	1,494,627
	Trade accounts receivable are recorded at the net invoice value and are not interest bearing. The Company considers receivables past due based on the contractual payment terms. Allowances for doubtful accounts are established based on various factors, including credit profiles of the Company’s customers, contractual terms and conditions, historical payments, and current economic trends. The Company reviews its allowances by assessing individual accounts receivable over a specific aging and amount. Accounts receivable are written off on a case-by-case basis, net of any amounts that may be collected.
	Capitalized Software Development Costs
	Costs incurred for the development of software that will be sold, leased or otherwise marketed are capitalized when technological feasibility has been established. Software development costs consist primarily of compensation of development personnel and related overhead incurred to develop new products and upgrade and enhance the Company’s current products, as well as fees paid to outside consultants. Capitalization of software development costs ceases and amortization of capitalized software development costs commences when the products are available for general release. For the three and six months ended March 31, 2014 and 2013, no software development costs were capitalized because the time period and cost incurred between technological feasibility and general release for all software product releases were not material.
	Fair Value of Equity Instruments
	The fair value of equity instruments involves significant estimates based on underlying assumptions made by management. The fair value for purchase rights under the Company’s equity plans is measured at the grant date using a Black-Scholes valuation model, which involves estimates of stock volatility, expected life of the instruments and other assumptions, and using the closing price of the Company’s common stock on the grant date for RSUs. The fair value of stock-based awards is recognized as an expense over the respective terms of the awards.
	Deferred Income Taxes
	Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the tax basis of such assets and liabilities. The Company maintains a valuation allowance against its deferred tax assets due to the uncertainty regarding the future realization of such assets, which is based on historical taxable income, projected future taxable income and the expected timing of the reversals of existing temporary differences. Until such time as the Company can demonstrate that it will no longer incur losses, or if the Company is unable to generate sufficient future taxable income, it could be required to maintain the valuation allowance against its deferred tax assets.
	Comprehensive Loss
	Comprehensive loss consists of net loss and unrealized gains and losses on available-for-sale securities. The following table summarizes the components of comprehensive loss:
		Three months ended						Six months ended
		March 31,						March 31,
		2014			2013			2014			2013
	Net loss	$	(2,193,017	)	$	(2,393,275	)	$	(3,661,317	)	$	(3,752,917	)
	Other comprehensive loss:
	Change in unrealized gains (losses) on marketable securities		6,686			(1,842	)		5,845			2,536
	Total comprehensive loss	$	(2,186,331	)	$	(2,395,117	)	$	(3,655,472	)	$	(3,750,381	)
	Included on the balance sheet at March 31, 2014 is an accumulated other comprehensive gain of $7,683, compared to an accumulated other comprehensive gain of $1,838 at September 30, 2013, related to the Company’s available-for-sale securities.

	Corporate debt securities, long-term			—		—		—			—
	Total		$	5,729,034	$	2,378	$	(540	)	$	5,730,872
	The cost of securities sold is based on the specific identification method. Amortization of premiums, accretion of discounts, interest, dividend income and realized gains and losses are included in investment income.
	The Company determines the appropriate designation of investments at the time of purchase and reevaluates such designation as of each balance sheet date. All of the Company’s investments are designated as available-for-sale debt securities. As of March 31, 2014 and September 30, 2013, the Company’s short-term investments have maturity dates of less than one year from the balance sheet date. The Company’s long-term investments have maturity dates of greater than one year from the balance sheet date; however, as of March 31, 2014 and September 30, 2013, the Company had no long-term investments.
	Available-for-sale marketable securities are carried at fair value as determined by quoted market prices for identical or similar assets, with unrealized gains and losses, net of tax, and reported as a separate component of stockholders’ equity. Management reviews the fair value of the portfolio at least monthly, and evaluates individual securities with fair value below amortized cost at the balance sheet date. For debt securities, in order to determine whether impairment is other than temporary, management must conclude whether the Company intends to sell the impaired security and whether it is more likely than not that the Company will be required to sell the security before recovering its amortized cost basis. If management intends to sell an impaired debt security or it is more likely than not that the Company will be required to sell the security prior to recovering its amortized cost basis, an other-than-temporary impairment is deemed to have occurred. The amount of an other-than-temporary impairment on debt securities related to a credit loss, or securities that management intends to sell before recovery, is recognized in earnings. The amount of an other-than-temporary impairment on debt securities related to other factors is recorded consistent with changes in the fair value of all other available-for-sale securities as a component of stockholders’ equity in other comprehensive income. No other-than-temporary impairment charges were recognized in the three and six months ended March 31, 2014 and 2013.
	Fair Value Measurements and Disclosures
	FASB ASC Topic 820, Fair Value Measurements (“ASC 820”) defines fair value, establishes a framework for measuring fair value under GAAP and enhances disclosures about fair value measurements. Fair value is defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. ASC 820 describes a fair value hierarchy based on the following three levels of inputs that may be used to measure fair value, of which the first two are considered observable and the last unobservable:
		•		Level 1—Quoted prices in active markets for identical assets or liabilities;
		•		Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, 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—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	Based on the fair value hierarchy, all of the Company’s investments are classified as Level 2, as represented in the following table:

	The fair value calculations for stock-based compensation awards to employees for the six months ended March 31, 2014 and 2013 were based on the following assumptions:
		Six Months Ended			Six Months Ended
		March 31, 2014			March 31, 2013
	Risk-free interest rate		0.12 – 0.63	%		0.18 – 0.81	%
	Expected life (years)		2.52			4.98
	Expected volatility		96	%		167	%
	Expected dividends		None			None
	The expected life of options granted is derived using assumed exercise rates based on historical exercise patterns and vesting terms, and represents the period of time that options granted are expected to be outstanding. Expected stock price volatility is based upon implied volatility and other factors, including historical volatility. After assessing all available information on either historical volatility, implied volatility, or both, the Company concluded that a combination of both historical and implied volatility provides the best estimate of expected volatility.
	As of March 31, 2014, the Company had $8,398,419 of unrecognized compensation expense related to outstanding stock options and RSUs expected to be recognized over a weighted-average period of approximately 2.7 years.
	2012 Incentive Plan
	In January 2012, the Company’s board of directors adopted the Mitek Systems, Inc. 2012 Incentive Plan (the “2012 Plan”), upon the recommendation of the compensation committee of the Company’s board of directors. The total number of shares of the Company’s common stock reserved for issuance under the 2012 Plan is 2,000,000 shares, plus that number of shares of the Company’s common stock that would otherwise return to the available pool of unissued shares reserved for awards under its 1999 Stock Option Plan, 2000 Stock Option Plan, 2002 Stock Option Plan, 2006 Stock Option Plan and 2010 Stock Option Plan (collectively, the “Prior Plans”). At the Company’s annual meeting of stockholders held on February 19, 2014, the Company’s stockholders approved an amendment to the 2012 Plan to increase the number of shares of the Company’s common stock available for future grant under the 2012 Plan from 2,000,000 to 4,000,000. As of March 31, 2014, (i) stock options to purchase 1,196,260 shares of the Company’s common stock and 590,472 RSUs were outstanding under the 2012 Plan, and 2,388,684 shares of the Company’s common stock were reserved for future grants under the 2012 Plan and (ii) stock options to purchase an aggregate of 1,511,803 shares of the Company’s common stock were outstanding under the Prior Plans.
	Director Restricted Stock Unit Plan
	In January 2011, the Company’s board of directors adopted the Mitek Systems, Inc. Director Restricted Stock Unit Plan, as amended and restated (the “Director Plan”). The total number of shares of the Company’s common stock reserved for issuance under the Director Plan is 1,000,000 shares. Under the Director Plan, RSUs may be granted to both employee and non-employee members of the board of directors of the Company. As of March 31, 2014, (i) 565,000 RSUs were outstanding under the Director Plan and (ii) 435,000 shares of the Company’s common stock were reserved for future grants under the Director Plan.

	4. INCOME TAXES
	The Company’s deferred tax assets are primarily comprised of federal and state net operating loss carryforwards. Such federal and state net operating loss carryforwards begin to expire in the fiscal years ending September 30, 2018 and September 30, 2014, respectively. The Company carries a deferred tax valuation allowance equal to 100% of the net deferred tax assets. In recording this allowance, management has considered a number of factors, particularly the Company’s recent history of sustained operating losses. Management has concluded that a valuation allowance is required for 100% of the net deferred tax assets as it is more likely than not that the deferred tax assets will not be realized.
	There can be no assurance that the Company will ever realize the benefit of any or all of the federal and state net operating loss carryforwards or the credit carryforwards, either due to ongoing operating losses or due to ownership changes, which may limit the usefulness of the net operating loss carryforwards. Due to the 100% valuation allowance on the net deferred tax assets, the Company does not anticipate that future changes in the Company’s unrecognized tax benefits will impact its effective tax rate.
	The Company’s policy is to classify interest and penalties related to income tax matters as income tax expense. The Company had no accrual for interest or penalties as of March 31, 2014 or March 31, 2013, and has not recognized interest and/or penalties in the statements of operations for the three and six months ended March 31, 2014 and 2013.

	Legal Matters
	USAA
	On March 29, 2012, United Services Automobile Association (“USAA”) filed a complaint in the U.S. District Court for the Western District of Texas San Antonio Division against the Company seeking, among other things, a declaratory judgment that USAA does not infringe certain of the Company’s patents relating to Mobile Deposit®, and that such patents are not enforceable against USAA. In addition, USAA alleges that it disclosed confidential information to the Company and that the Company used such information in its patents and Mobile Deposit® product in an unspecified manner. USAA seeks damages and injunctive relief. USAA subsequently amended its pleadings to assert a claim for false advertising and reverse palming off under the Lanham Act, and to seek reimbursement under the parties’ license agreement.
	On April 12, 2012, the Company filed a lawsuit against USAA in the U.S. District Court for the District of Delaware, alleging that USAA infringes five of the Company’s patents relating to image capture on mobile devices, breached the parties’ license agreement by using the Company’s products beyond the scope of the agreed-upon license terms and breached the parties’ license agreement by disclosing confidential pricing and other confidential information for the Company’s legacy product installation in the lawsuit USAA filed in Texas.
	The courts consolidated the foregoing cases in the U.S. District Court for the Western District of Texas, and on November 19, 2012, the Company answered USAA’s various claims and counterclaims, moved to dismiss USAA’s Lanham Act cause of action and filed a counterclaim against USAA for violation of the Lanham Act. On February 15, 2013, the court granted the Company’s motion and dismissed USAA’s Lanham Act claim.
	The Company believes USAA’s claims are without merit and intends to vigorously defend against those claims and pursue its claims against USAA. The Company does not believe that the results of USAA’s claims will have a material adverse effect on its financial condition or results of operations.
	Top Image Systems Ltd.
	On September 26, 2012, the Company filed a lawsuit against Israeli-based Top Image Systems Ltd. and TIS America Inc. (collectively, “TISA”) in the U.S. District Court for the District of Delaware, alleging that TISA infringes five of the Company’s patents relating to image capture on mobile devices. The Company is seeking damages against TISA and injunctive relief to prevent them from selling their mobile imaging products.
	On January 7, 2013, TISA answered the Company’s complaint by denying the allegations and raising several affirmative defenses. On January 11, 2013, the Company amended its complaint to add its sixth patent, which had recently been issued and also relates to image capture on mobile devices. On January 28, 2013, TISA responded to the Company’s amended complaint by again denying the allegations and raising the same affirmative defenses that they raised in their answer to the Company’s initial complaint.
	Other Legal Matters
	In addition to the foregoing, the Company is subject to various claims and legal proceedings arising in the ordinary course of its business. While any legal proceeding has an element of uncertainty, the Company believes that the disposition of such matters, in the aggregate, will not have a material effect on the Company’s financial condition or results of operations.
	Facility Lease
	The Company’s principal executive offices, as well as its research and development facility, are located in approximately 22,523 square feet of office space in San Diego, California. The term of the lease for the Company’s offices continues through June 30, 2019. The annual base rent under the lease is approximately $471,000 per year and is subject to annual increases of approximately 3% per year. In connection with the lease, the Company received tenant improvement allowances totaling $675,690. These lease incentives are being amortized as a reduction of rent expense over the term of the lease. As of March 31, 2014, the unamortized balance of the lease incentives was $550,749, of which $104,905 has been included in other current liabilities and $445,844 has been included in other non-current liabilities. Under the terms of the lease, the Company issued a standby letter of credit to the landlord that allows for one or more draws of up to $210,000 over the term of the lease. The Company believes its existing properties are in good condition and are sufficient and suitable for the conduct of its business.

Revenue and Vendor Concentrations	'
	6. REVENUE AND VENDOR CONCENTRATIONS
	Revenue Concentration
	For the three months ended March 31, 2014, the Company derived revenue of $1,644,145 from one customer, accounting for 37% of the Company’s total revenue, compared to revenue for the three months ended March 31, 2013 of $1,299,241 derived from two customers, accounting for 30% and 10%, respectively, of the Company’s total revenue. For the six months ended March 31, 2014, the Company derived revenue of $4,055,587 from two customers, accounting for 35% and 11%, respectively, of the Company’s total revenue, compared to revenue for the six months ended March 31, 2013 of $2,619,466 derived from two customers, accounting for 25% and 15%, respectively, of the Company’s total revenue. The corresponding accounts receivable balances of customers from which revenues were in excess of 10% of total revenue were $1,471,245 and $189,775, respectively, at March 31, 2014 and 2013.
	The Company’s revenue is derived primarily from the sale by the Company to channel partners, including systems integrators and resellers, and end-users of licenses to sell products covered by the Company’s patented technologies. These contractual arrangements do not obligate the Company’s channel partners to order, purchase or distribute any fixed or minimum quantities of the Company’s products. In most cases, the channel partners purchase the license from the Company after they receive an order from an end-user. The channel partners receive orders from various individual end-users; therefore, the sale of a license to a channel partner may represent sales to multiple end-users. End-users can purchase the Company’s products through more than one channel partner.
	Revenues can fluctuate based on the timing of license renewals by channel partners. When a channel partner purchases or renews a license, the Company receives a license fee in consideration for the grant of a license to sell the Company’s products and there are no future payment obligations related to such agreement; therefore, the license fee the Company receives with respect to a particular license renewal in one period does not have a correlation with revenue in future periods. During the last several quarters, sales of licenses to one or more channel partners have comprised a significant part of the Company’s revenue. This is attributable to the timing of renewals or purchases of licenses and does not represent a dependence on any single channel partner. The Company believes that it is not dependent upon any single channel partner, even those from which revenues were in excess of 10% of the Company’s total revenue in a specific reporting period, and that the loss or termination of the Company’s relationship with any such channel partner would not have a material adverse effect on the Company’s future operations because either the Company or another channel partner could sell the Company’s products to the end-user that purchased from the channel partner the Company lost.
	During the three and six months ended March 31, 2014, international sales accounted for approximately 6% and 7%, respectively, of the Company’s total revenue. International sales accounted for approximately 2% of the Company’s total revenue for both the three and six months ended March 31, 2013. The Company sells its products in U.S. currency only.
	Vendor Concentration
	The Company purchases its integrated software components from multiple third-party software providers at competitive prices. For the three and six months ended March 31, 2014 and 2013, the Company did not make purchases from any one vendor comprising 10% or more of the Company’s total purchases. The Company has entered into contractual relationships with some of its vendors; however, the Company does not believe it is substantially dependent upon nor exposed to any significant concentration risk related to purchases from any of its vendors, given the availability of alternative sources for its necessary integrated software components.

Basis of Presentation	'
	Basis of Presentation
	The accompanying unaudited financial statements of the Company as of March 31, 2014 have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and, accordingly, they do not include all information and footnote disclosures required by accounting principles generally accepted in the U.S. (“GAAP”). The Company believes the footnotes and other disclosures made in the financial statements are adequate for a fair presentation of the results of the interim periods presented. The financial statements include all adjustments (solely of a normal recurring nature) which are, in the opinion of management, necessary to make the information presented not misleading. You should read these financial statements and the accompanying notes in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2013, filed with the U.S. Securities and Exchange Commission (the “SEC”) on December 12, 2013 (the “Form 10-K”).
	Results for the three and six months ended March 31, 2014 are not necessarily indicative of results for any other interim period or for a full year.
Reclassifications	'
	Reclassifications
	Certain prior period amounts have been reclassified to conform to the current period presentation. These reclassifications do not impact the reported net loss for such periods and do not have a material impact on the presentation of the overall financial statements.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses and the related disclosure of contingent assets and liabilities. On an ongoing basis, management reviews its estimates based upon currently available information. Actual future results could differ materially from those estimates.
Net Loss Per Share	'
	Net Loss Per Share
	The Company calculates net loss per share in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 260, Earnings Per Share. Basic and diluted net loss per share are based on the weighted-average number of common shares outstanding during the period, without giving effect to potentially dilutive securities. In a period with a net loss position, potentially dilutive securities, such as options, warrants and restricted stock units (“RSUs”), are not included in the calculation of diluted net loss because to do so would be antidilutive, and the number of shares used to calculate basic and diluted net loss is the same.
	For the three and six months ended March 31, 2014 and 2013, the following potentially dilutive common shares were excluded from the calculation of net loss per share, as they would have been antidilutive:
		Three and six months ended

Revenue Recognition	'
	Revenue Recognition
	Revenue from sales of software licenses sold through direct and indirect channels is recognized upon shipment of the related product, if the requirements of FASB ASC Topic 985-605, Software Revenue Recognition (“ASC 985-605”) are met, including evidence of an arrangement, delivery, fixed or determinable fee, collectability and vendor specific objective evidence (“VSOE”) of the fair value of the undelivered element. If the requirements of ASC 985-605 are not met at the date of shipment, revenue is not recognized until such elements are known or resolved. Revenue from customer support services, or maintenance revenue, includes post-contract support and the rights to unspecified upgrades and enhancements. VSOE of fair value for customer support services is determined by reference to the price the customer pays for such element when sold separately; that is, the renewal rate offered to customers. Revenue derived from professional services primarily includes consulting, implementation, and training. Revenue from fixed fee service engagements is recognized after the services are performed using the completed performance method. Revenue from time and materials service engagements is generally recognized as the services are performed.
	In those instances when objective and reliable evidence of fair value exists for the undelivered items but not for the delivered items, the residual method is used to allocate the arrangement consideration. Under the residual method, the amount of arrangement consideration allocated to the delivered items equals the total arrangement consideration less the aggregate fair value of the undelivered items. Revenue from post-contract customer support is recognized ratably over the term of the contract. Certain customers have agreements that provide for usage fees above fixed minimums. Fixed minimum transaction fees are recognized as revenue ratably over the term of the arrangement. Usage fees above fixed minimums are recognized as revenue when such amounts are reasonably estimable and billable. Revenue from professional services is recognized when such services are delivered. When a software sales arrangement requires professional services related to significant production, modification or customization of software, or when a customer considers professional services essential to the functionality of the software product, revenue is recognized based on predetermined milestone objectives required to complete the project, as those milestone objectives are deemed to be substantive in relation to the work performed. Any expected losses on contracts in progress are recorded in the period in which the losses become probable and reasonably estimable.
Accounts Receivable and Allowance for Doubtful Accounts	'
	Accounts Receivable and Allowance for Doubtful Accounts
	Accounts receivable, net, is as follows:
		March 31,			September 30,
		2014			2013
	Accounts receivable	$	3,122,819		$	1,506,627
	Less: Allowance for doubtful accounts		(7,500	)		(12,000	)
	Accounts receivable, net	$	3,115,319		$	1,494,627
	Trade accounts receivable are recorded at the net invoice value and are not interest bearing. The Company considers receivables past due based on the contractual payment terms. Allowances for doubtful accounts are established based on various factors, including credit profiles of the Company’s customers, contractual terms and conditions, historical payments, and current economic trends. The Company reviews its allowances by assessing individual accounts receivable over a specific aging and amount. Accounts receivable are written off on a case-by-case basis, net of any amounts that may be collected.
Capitalized Software Development Costs	'
	Capitalized Software Development Costs
	Costs incurred for the development of software that will be sold, leased or otherwise marketed are capitalized when technological feasibility has been established. Software development costs consist primarily of compensation of development personnel and related overhead incurred to develop new products and upgrade and enhance the Company’s current products, as well as fees paid to outside consultants. Capitalization of software development costs ceases and amortization of capitalized software development costs commences when the products are available for general release. For the three and six months ended March 31, 2014 and 2013, no software development costs were capitalized because the time period and cost incurred between technological feasibility and general release for all software product releases were not material.
Fair Value of Equity Instruments	'
	Fair Value of Equity Instruments
	The fair value of equity instruments involves significant estimates based on underlying assumptions made by management. The fair value for purchase rights under the Company’s equity plans is measured at the grant date using a Black-Scholes valuation model, which involves estimates of stock volatility, expected life of the instruments and other assumptions, and using the closing price of the Company’s common stock on the grant date for RSUs. The fair value of stock-based awards is recognized as an expense over the respective terms of the awards.

	Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the tax basis of such assets and liabilities. The Company maintains a valuation allowance against its deferred tax assets due to the uncertainty regarding the future realization of such assets, which is based on historical taxable income, projected future taxable income and the expected timing of the reversals of existing temporary differences. Until such time as the Company can demonstrate that it will no longer incur losses, or if the Company is unable to generate sufficient future taxable income, it could be required to maintain the valuation allowance against its deferred tax assets.
