Payment Register with Multiple Deduction
This module extend invoice(s)'s register payment feature, from "Mark invoice as fully paid" with a single writeoff amount, to "Mark invoice as fully paid (multi deduct)" which allow multiple deduction amounts.
Note: We use the word "Deduction", as the diff amount can be anything not only to writeoff.
auto_awesome What this module does
AI-generated from the code · Odoo 18.0Adds a new option in the Register Payment wizard to mark an invoice as fully paid using several deduction lines instead of a single write-off amount. Each deduction can have its own account, label, amount and analytic distribution.
When you register a payment on an invoice, the wizard now offers an extra choice in the payment difference handling field: "Mark invoice as fully paid (multi deduct)". Selecting it replaces the single write-off account with a table of deductions.
In that table you can add as many deduction lines as needed. Each line has a label, an amount, an optional account, and an analytic distribution. A line can also be flagged as "Open" to keep it open instead of closing it against the invoice; when you tick Open, the account and label are cleared automatically.
A "Remainings" field shows how much of the payment difference is still not covered by the deductions. The module blocks saving if the total of the deduction lines does not exactly match the payment difference, so the invoice is always fully reconciled.
When the payment is created, each deduction line becomes a write-off line on the payment, with the correct sign depending on whether the payment is incoming or outgoing, and with the analytic distribution you entered. The module also adds an analytic distribution field to the standard single write-off option, and marks generated write-off lines so they can be identified.
It touches the payment register wizard, invoice lines, and adds a new deduction model. Access is given to users with billing rights.
