Revenue recognition Effective October 1, 2018, the Company adopted Accounting Standards Codification Topic 606, "Revenue from Contracts with Customers" ("ASC 606") using the modified retrospective method. Results for the reporting period beginning after October 1, 2018 are presented under ASC 606, while prior period amounts have not been adjusted and continue to be reported in accordance with the Company's historic accounting under Topic 605. Management has determined that the adoption of ASC 606 did not impact the Company's previously reported financial statements in any prior period nor did it result in a cumulative effect adjustment to opening retained earnings. Under ASC 606, the Company recognizes revenue when a customer obtains control of promised goods, in an amount that reflects the consideration which the Company expects to receive in exchange for the goods. To determine revenue recognition for arrangements within the scope of ASC 606, the Company performs the following five steps: (1) identify the contracts with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when or as the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods it transfers to the customer. The Company currently recognizes revenue from application users in the form of membership subscription and a la carte online credit purchases. Membership subscription is a service package which enables members to enjoy additional functions and privileges. Members pay in advance, primarily by using a debit card or through mobile app stores, and, subject to certain conditions identified in the Company's terms and conditions, all purchases are final and nonrefundable. Fees collected, in advance for membership subscription, are deferred and recognized as revenue using the straight-line method over the terms of the applicable membership period, which primarily range from one to three months. Membership subscription revenue is insignificant for the years ended September 30, 2019 and 2018. A la carte online credit purchases are non-refundable and the risk passes to users when users pay for a la carte features. Revenue from the purchase of a la carte features is recognized at a point in time when the features are enabled upon users paying for the purchase. In the year ended September 30, 2019, the Company also generated revenue from development and sale of application. Revenue from development and sale of application is recognized at a point in time when the application is delivered to and accepted by the customer. Such revenue consists of less than 10% of the total revenue for the year ended September 30, 2019. Revenue was recorded on a gross basis, net of surcharges and value added tax ("VAT") of gross sales. The Company recorded revenue on a gross basis because the Company has the following indicators for gross reporting: being the primary obligor of the sales arrangements that has latitude in establishing prices, having discretion in suppliers selection and assuming credit risks on receivables from customers.
