The bill-to address is where you send customer invoices and other billing-related information. In most cases, the bill-to address will be the customer's address of record. The ship-to address is the physical address where customer shipments are sent. One customer can have multiple ship-to addresses. For example, let's say your customer is a retail chain—and the chain has dozens of outlets. If you ship to each outlet, then the address for each would be entered as a ship-to address. In this way, sales orders can be tailored to each shipment address.
