auto_awesome What this module does
AI-generated from the code · Odoo 19.0Lets sales users enter a fixed money discount on each sales order line instead of only a percentage. The equivalent percentage is calculated automatically, shown on the quotation, portal and invoice, and checked for consistency.
On a sales order line you get an extra field called "Discount (Fixed)" where you can type a discount as an amount of money rather than a percentage. As soon as you enter it, Odoo recalculates the usual percentage discount on that line so the totals stay correct, and the tax calculation uses the exact amount to avoid rounding differences.
- The field is visible in the sales order form and in the list of order lines, but only for users who have the discount permission group.
- If both a fixed amount and a percentage are filled in and they do not match, Odoo blocks the save with an error asking you to correct one of them.
- When the sales order is turned into an invoice, the fixed discount amount is carried over to the invoice line.
- On the printed quotation/sales order report, when any line has a fixed discount, the discount column shows the amount and the equivalent percentage.
- The customer portal page for the order also shows a "Disc. Fixed Amount" column and displays the discounted unit price.
It touches sales order lines (sale.order.line), sales orders (sale.order), customer invoices (account.move), the quotation report and the customer portal page.
