A system for enabling the remote ordering of products, primarily for use in a multi-vendor system, is disclosed. Orders are placed remotely, such as through wireless devices connected to a central server. The central server, in turn, is in communication (wireless or otherwise) with a server located at one or more venues within the organization operating the system. The one or more venues provide products or services available for ordering through the system. Where multiple venues are involved, the system is designed to handle differences in the product or service availability at those different venues, and provides for an ability to make corrections to orders that may be or may become necessary on account of those differences. The system provides for multiple options through which users can pay for and receive orders, and also provides methods for synchronizing the remote ordering system with pre-existing, conventional methods of ordering and product/service order fulfillment.
