The module allows to add advance payments on purchase orders and Request for Quotation. The advance payments are allowed even before confirmation and before starting the billing process.
auto_awesome What this module does
AI-generated from the code · Odoo 19.0Lets you pay a supplier in advance directly from a purchase order or request for quotation, before any bill is received. The order then shows how much is still due and whether it is fully, partially or not paid.
This module adds advance payments to purchase orders. On a purchase order form you get a "Pay purchase advanced" button (visible to invoicing users) that opens a small "Advance Payment" window where you choose the bank or cash journal, the payment method, the amount to pay in advance, the date and an optional reference. The window shows the order due amount and converts the amount into the order currency when the journal uses a different one.
- The amount must be positive and cannot exceed the remaining amount on the order; otherwise Odoo refuses to save.
- Confirming the window creates a supplier payment linked to the purchase order, and a "Payment advances" tab on the order lists all such payments.
- The order form shows a "Residual amount" next to the totals, and the order lists show a coloured badge (Not Paid, Partially Paid, Paid) plus the residual amount.
- A new "Advance Payments" menu under the Payables section of Accounting lists supplier advance payments, with a filter for vendor advance payments and for not reconciled ones.
In Settings, under Purchase invoicing, two options can be switched on: automatically posting advance payments created from purchase orders, and automatically reconciling them when the related bill is confirmed. The module touches purchase.order, account.payment, account.move and the purchase settings screen.
