Most fields in an invoice generated by invoice post cannot be changed. The financial information, such as the total invoice amount, the accounts that are updated when the transaction is posted, and the tax rates and amounts, is defined when you create, ship, and post the original sales order. You can view the resulting customer invoice in Customer Invoice View, and in most cases, can process the invoice immediately using customer payments.

You can optionally modify the following fields on the specified tabs of a sales-related invoice.

Customer invoices can be saved in draft format when Draft Instances is selected in System/User Settings, Change System Setting. When you save a record in draft format, none of the system validations are executed. You can then return later to complete the record by choosing the Customer Invoice Browse Drafts activity and selecting the record you want to finish from the list. For more information on drafts, see Introduction to QAD Enterprise Applications User Guide.
