Revenue is recognized when it is realized or realizable and earned, in accordance with ASC 605, Revenue Recognition (ASC 605). Recognition occurs when all of the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been performed; (3) the sellers price to the buyer is fixed or determinable; and (4) collectability is reasonably assured. The Company accrues for rights of refund, processing errors or penalties, or other related allowances based on historical experience. The majority of the Company's gross revenue for the years ended September 30, 2019, 2018 and 2017 is derived from volume-based payment processing fees (discount fees) and other related fixed transaction or service fees. The remainder is comprised of sales of software licensing subscriptions, ongoing support, and other POS-related solutions the Company provides to its clients directly and through its processing bank relationships. Discount fees represent a percentage of the dollar amount of each credit or debit transaction processed. Discount fees are recognized at the time the merchants transactions are processed. The Company follows the requirements of ASC 605-45 Revenue RecognitionPrincipal Agent Considerations, in determining its merchant processing services revenue reporting. Generally, where the Company has control over merchant pricing, merchant portability, credit risk and ultimate responsibility for the merchant relationship, revenues are reported at the time of sale on a gross basis equal to the full amount of the discount charged to the merchant. This amount includes interchange fees paid to card issuing banks and assessments paid to payment card networks pursuant to which such parties receive payments based primarily on processing volume for particular groups of merchants. Revenues generated from merchant portfolios where the Company does not have control over merchant pricing, liability for merchant losses or credit risk or rights of portability are reported net of interchange and other fees. Revenues are also derived from a variety of fixed transaction or service fees, including authorization fees, convenience fees, statement fees, annual fees, and fees for other miscellaneous services, such as handling chargebacks. Revenues derived from service fees are recognized at the time the services are performed and there are no further performance obligations. Revenue from the sale of equipment is recognized upon transfer of ownership and delivery to the customer, after which there are no further performance obligations. Revenues from sales of the Companys software licensing subscriptions are recognized when they are realized or realizable and earned. Contractual arrangements are evaluated for indications that multiple element arrangements may exist, including instances where more-than-incidental software deliverables are included. Arrangements may contain multiple elements, such as hardware, software products, maintenance, and professional installation and training services. Revenues are allocated to each element based on the selling price hierarchy. The selling price for a deliverable is based on vendor specific objective evidence of selling price, if available, third party evidence, or estimated selling price. The Company establishes estimated selling price, based on the judgment of the Company's management, considering internal factors such as margin objectives, pricing practices and controls, customer segment pricing strategies and the product life cycle. In arrangements with multiple elements, the Company determines allocation of the transaction price at inception of the arrangement based on the relative selling price of each unit of accounting. In multiple element arrangements where more-than-incidental software deliverables are included, the Company applies the residual method to determine the amount of software license revenues to be recognized. Under the residual method, if fair value exists for undelivered elements in a multiple-element arrangement, such fair value of the undelivered elements is deferred with the remaining portion of the arrangement consideration recognized upon delivery of the software license or services arrangement. The Company allocates the fair value of each element of a software-related multiple-element arrangement based upon its fair value as determined by vendor specific objective evidence of selling price, with any remaining amount allocated to the software license. If evidence of the fair value cannot be established for the undelivered elements of a software arrangement, then the entire amount of revenue under the arrangement is deferred until these elements have been delivered or objective evidence can be established. These amounts, if any, are included in deferred revenue in the consolidated balance sheets. Revenues related to software licensing subscriptions, maintenance or other support services with terms greater than one month are recognized ratably over the term of the agreement. Revenues from sales of the Company  s combined hardware and software element are recognized when they are realized or realizable and earned which has been determined to be upon the delivery of the product. Revenues derived from service fees are recognized at the time the services are performed and there are no further performance obligations. The Companys training, installation, and repair services are recognized as revenue as these services are performed. Deferred revenue represents amounts billed to customers by the Company for services contracts. The initial prepaid contract agreement balance is deferred. The balance is then recognized as the services are provided over the contract term. Deferred revenue that is expected to be recognized as revenue within one year is recorded as short-term deferred revenue and the remaining portion is recorded as other long-term liabilities in the consolidated balance sheets. Interchange and Network Fees and Other Cost of Services Interchange and network fees consist primarily of fees that are directly related to discount fee revenue. These include interchange fees paid to issuers and assessment fees payable to card associations, which are a percentage of the processing volume the Company generates from Visa and Mastercard, as well as fees charged by card-issuing banks. Other costs of services include costs directly attributable to processing and bank sponsorship costs, which may not be based on a percentage of volume. These costs also include related costs such as residual payments to sales groups, which are based on a percentage of the net revenues generated from merchant referrals. In certain merchant processing bank relationships the Company is liable for chargebacks against a merchant equal to the volume of the transaction. Losses resulting from chargebacks against a merchant are included in other cost of services on the accompanying consolidated statement of operations. The Company evaluates its risk for such transactions and estimates its potential loss from chargebacks based primarily on historical experience and other relevant factors. The reserve for merchant losses is included within accrued expenses and other current liabilities on the accompanying consolidated balance sheets. The cost of equipment sold is also included in other cost of services. Interchange and other costs of services are recognized at the time the merchant's transactions are processed. The Company accounts for all governmental taxes associated with revenue transactions on a net basis.
