Odoo blocks any payment until an invoice or bill exists, yet customers pay deposits at quotation stage and vendors demand advances upfront. Teams create premature invoices or record loose, unlinked payments that someone must hunt down and reconcile by hand later.

Click Register Payment on the order itself, confirm the amount against the live total, and post the advance with its own journal entry. When the invoice or bill is created, the advance is applied and reconciled automatically — pay now, invoice later, reconcile itself.

The Register Payment button, the Partially Advanced badge, and an Advances smart button live right on the sale order.

The wizard shows order total, already paid and remaining, accepts an amount or a percentage, and offers reuse of an existing advance.

The Advance Payments tab lists every deposit with paid, remaining, status and whether it has been applied.

The invoice created from the order is already part-paid — the advance was applied and reconciled automatically, lowering the amount due.

Each advance payment links back to its originating order and to the invoice it has been reconciled against.

The sale order list gains an Advance Status column — Unpaid, Partially Advanced or Fully Advanced — ready to filter and group.

The same Register Payment button, badge and Advances smart button appear on purchase orders for supplier advances.

The purchase order Advance Payments tab tracks paid, remaining and status for every vendor advance.

Purchase orders carry the same Advance Status column, so payables can be triaged alongside receivables.

Settings control automatic reconciliation on invoicing and optional auto-registration of advances when sale or purchase orders are confirmed.

A branded advance receipt for customers — and a vendor remittance advice — prints directly from the order with total, paid and remaining.
