Point of Sale (POS): Workflows: PoS Sales Process
Purpose
Point of Sale (PoS) is used to provide a straight-forward approach to fulfilling orders for cash-and-carry customers that wish to pickup goods themselves directly from the warehouse.

Once there, click Continue Selling or New Session on a session card.
