Revenue Recognition On January 1, 2018, Envision adopted the revenue standards of Financial Accounting Standards Board Update No. 2014-09: Revenue from Contracts with Customers (Topic 606). The core principle of this Topic is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue is recognized in accordance with that core principle by applying 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; and 5) recognize revenue when (or as) we satisfy a performance obligation. Revenues are primarily derived from the direct sales of manufactured products. Revenues may also consist of maintenance fees for the maintenance of previously sold products, and revenues from sales of professional services. Revenues from inventoried product sales are recognized upon the final delivery of such product to the customer or when legal transfer of ownership takes place. Revenue values are fixed price arrangements determined at the time an order is placed or a contract is entered into. The customer is typically obligated to make payment for such products within a 30-45 day period after delivery. Revenues from maintenance fees are recognized equally over the period of the maintenance term. Revenue values are fixed price arrangements determined at the time an order is placed or a contract is entered into. The customer is typically obligated to make payment for the service in advance of the maintenance period. Revenues from professional services are recognized as services are performed. Revenue values are based upon fixed fee arrangements or hourly fee-based arrangements with agreed to hourly rates of service categories in line with expertise requirements. These services are billed to a customer as such services are provided and the customer will be obligated to make payments for such services typically within a 30-45 day period. The Company includes shipping and handling fees billed to customers as revenues, and shipping and handling costs as cost of revenues. Any deposits received from a customer prior to delivery of the purchased product or monies paid prior to the period for which a service is provided are accounted for as deferred revenue on the balance sheet. Sales tax is recorded on a net basis and excluded from revenue. The Company generally provides a standard one-year warranty on its products for materials and workmanship but may provide multiple year warranties as negotiated, and will pass on the warranties from its vendors, if any, which generally covers this one-year period. In accordance with ASC 450-20-25, the Company accrues for product warranties when the loss is probable and can be reasonably estimated. At June 30, 2019, the Company has no product warranty accrual given the Companys de minimis historical financial warranty experience.
