This article gives a quick overview of the tablet workflow. There are many other details and scenarios involved in managing tablet orders, but this will give you a general idea of how it all works.
Customer places an order online (or through a mobile app)
Restaurant receives order in the Pending Orders on the tablet.
Restaurant makes order decision: Reject order - customer is notified through email that their order has been rejected. Workflow ends. Adjust order - customer is notified through email that their order time has been adjusted. Confirm order - customer is notified through email that their order has been confirmed. Proceed to #4.
Order becomes an Active Order. Restaurant begins cooking food at an appropriate time.
Restaurant marks food as Ready for Pick Up once the order is complete (or Out for Delivery once the courier has left).
Customer is notified through email their order is ready and/or on its way.
Customer picks up order (or order is delivered). Order is marked as complete.
