Accounting workflow and the automatic generation of invoices¶

In general, when you use all of Open ERP's functionality, invoices don't need to be entered manually. Draft invoices are generated automatically from other documents such as Purchase Orders.
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's nothing to stop users creating their own draft invoices if they want to.
You can create draft invoice manually : Finantial Management / Invoices / Customer Invoices / New Customer Invoice
The information that's 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).
There are several advantages in working with Draft invoices:
You've got an intermediate validation state before the invoice is approved. This is useful when your accountants aren't 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're also able to list all of the invoices awaiting approval.
Open or Pro-Forma Invoices¶
You can approve (or validate) an invoice in the Open or Pro Forma state. A Pro Forma invoice doesn't yet have an invoice number or accounting entries. It is something more formal than a draft invoice and can later be converted to an open invoice.
Reconciling invoice entries and payments¶
In Open ERP an invoice is considered to be paid when its accounting entries have been reconciled with the payment entries. If there hasn't been a reconciliation an invoice can remain in the open state until you have entered the payment.
Payment and reconciliation
To avoid surprises, it's important to understand the idea of reconciliation and its link with invoice payment.
You'll find both a Reconciled field and the Paid checkbox on an invoice. They differ from each other only if an invoice has been paid (using reconciliation of records) but has subsequently been marked as unreconciled.
Reconciliation links entries in an account that cancel each other out – they're reconciled to each other (sum of credits = sum of debits).
This is generally applied to payments against corresponding invoices.
Without the reconciliation process, Open ERP would be incapable of marking invoices that have been paid. Suppose that you've got the following situation for the Smith and Offspring customer:
发票 145: 50，
发票 167: 120，
发票 184: 70。
If you receive a payment of 120, Open ERP will delay reconciliation because there's a choice of invoices to pay. It could either reconcile the payment against invoices 145 and 184 or against invoice 167.
You can cancel an invoice if the Allow Cancelling Entries function has been activated in the journal and the entries haven't yet been reconciled. You could then move it from Canceled , through the Draft state to modify it and regenerate it.
Treatment in Lots
Usually, different transactions are grouped together and handled at the same time rather than invoice by invoice. This is called batch work or lot handling.
You can select several documents in the list of invoices: check the checkboxes of the interesting lines using the web client and click the appropriate shortcut button at the right; or shift-click the lines using the mouse in the GTK client and use the action or print button at the top – these give you the option of a number of possible actions on the selected objects.
At regular intervals, and independently of the invoices, an automatic import procedure or a manual accounts procedure can be used to bring in bank statements. These comprise all of the payments of suppliers and customers and general transactions, such as between accounts.
When an account is validated, the corresponding accounting entries are automatically generated by Open ERP.
Invoices are marked as paid when accounting entries on the invoice have been reconciled with accounting entries about their payment.
This reconciliation transaction can be carried out at various places in the process, depending on your preference:
at data entry for the accounting statement,
manually from the account records,
automatically using Open ERP's intelligent reconciliation.
You can create the accounting records directly, without using the invoice and account statements. To do this, use the rapid data entry form in a journal. Some accountants prefer this approach because they're used to thinking in terms of accounting records rather than in terms of invoices and payments.
You should really use the forms designed for invoices and bank statements rather than manual data entry records, however. These are simpler and are managed within an error-controlling system.
A records-based system¶
All the accounting transactions in Open ERP are based on records, whether they're created by an invoice or created directly.
So partner reminders are generated quickly from the list of unreconciled entries in the trade receivables account for that partner. In a single reminder you'll find the whole set of unpaid invoices as well as unreconciled payments, such as advance payments.
Similarly, financial statements such as the general ledger, account balance, aged balance (or chronological balance) and the various journals, are all based on accounting entries. It doesn't matter if you generated the entry from an invoice form or directly in the invoice journal. It's the same for the tax declaration and other statutory financial statements.
When using integrated accounting, you should still go through the standard billing process because some modules are directly dependent on invoice documents. For example, a customer sale order can be configured to wait for payment of the invoice before triggering a delivery. In such a case, Open ERP automatically generates a draft invoice to send to the client.
