13.1 Accounting Workflow and Automatic Invoice Creation

The chart Accounting workflow for invoicing and payment shows the financial workflow followed by each invoice. Figure 13.1: Accounting workflow for invoicing and payment In general, when you use all of OpenERP’s functionality, invoices do not need to be entered manually. Draft invoices are generated automatically from other documents such as Purchase Orders.

13.1.1 Draft Invoices

The system generates invoice proposals which are initially set to the Draft state. While these invoices remain unconfirmed they have no accounting impact within the system. There is nothing to stop users creating their own draft invoices if they want to. You can create draft customer invoice manually using the menu Accounting → Customers → Customer Invoices. The information that is needed for invoicing is automatically taken from the Partner form such as payment conditions and the invoice address or from the Product such as the account to be used or from a combination of the two such as applicable Taxes and the Price of the product. Tip: Draft invoices There are several advantages in working with Draft invoices: • You have got an intermediate validation state before the invoice is approved. This is useful when your accountants are not the people creating the initial invoice, but are still required to approve it before the invoice is entered into the accounts. • It enables you to create invoices in advance, without approving them at the same time. You are also able to list all of the invoices awaiting approval.

13.1.2 Open or Pro Forma Invoices

You can approve or validate an invoice in the Open or Pro Forma state. A Pro Forma invoice does not yet have an invoice number, but the accounting entries on the invoice that is created correspond to the amounts that OpenERP will record as the customer’s payables.
