Bank

Odoo uses a two-step method for handling invoice payments:

1. Invoice Validation

   • When an invoice (customer or vendor) is created and validated, it is posted in the accounting system.

   • At this stage, the invoice is considered issued but not yet paid.

2. Payment Reconciliation via Bank Statement

   • Payments are not marked directly on the invoice. Instead, they are recorded through a bank statement (or payment journal entry).

   • The reconciliation process matches the payment with the invoice, which then updates the invoice status to Paid.

Why Odoo uses this approach

• Accounting Accuracy: In real accounting, invoices and payments are separate documents. An invoice represents what is owed, while the bank statement represents actual cash movement.

• Audit Trail: By requiring reconciliation, Odoo ensures a clear and auditable link between invoices and payments.

• Bank Integration: Many businesses import bank statements directly. This design makes it easier to match real transactions with Odoo invoices.

• Flexibility: A single payment can cover multiple invoices, or one invoice can be paid in multiple installments. The reconciliation process handles these cases correctly.

“Mark as Paid” Button

Odoo includes a Mark as Paid action in invoicing for convenience. However:

• This action does not immediately mark the invoice as fully paid; instead, it moves the invoice into the “In Payment” state.

• What it really does is create a payment entry linked to the invoice, simulating that a payment has been made.

• The final status of “Paid” is only reached after reconciliation with the corresponding bank statement or journal entry.

Reason for this design

• It allows users to record payments manually when they don’t use automated bank feeds or imported statements.

• It supports scenarios where payments are received but not yet reconciled, keeping accounting consistent.

• It provides flexibility for small teams who may want a shortcut, while still enforcing reconciliation for proper accounting practice.
