# Invoices

An Apptiflo Invoice documents the total amount sold to a Customer Account and is created when a Sales Order is received. All updates to the Sales Order automatically update the linked Invoice. The Invoice total is the expected payment from the Customer Account.

Accounts may also create Invoices independent of any Sales Orders. Independent invoices will generate a Bill in the Customer's Account.
