When you create a billing document, data is copied from the sales order and the delivery document to the billing document. Delivery items, as well as order items (for example, services), can be references for the billing document.
The billing document serves several important functions:
- It is the sales and distribution document that helps you to generate invoices.
- It serves as a data source for financial accounting (FI) to help you to monitor and process customer payments.
- Typically, creating a billing document automatically updates the G/L accounts.
