Point of Sale [POS] in the online world is the point in the sales process or flow of a website or ap where one asks for the money, and the customer pays up. Actual delivery of the product to the customer may occur instantly (through an immediate download or by granting access to something online), or it may be delayed (where an actual product needs to be packed and shipped to the customer IRL).
