Purchase Global Discount
Apply per-line, global, or fixed-amount discounts to purchase orders — with role control and bill sync.
Overview
Purchase Global Discount adds a discount wizard to purchase orders in Odoo. From inside the PO, a buyer picks one of three discount methods — a uniform percentage on every line, a single percentage on the subtotal, or a fixed-amount deduction from the total — and the order recalculates immediately.
Built by TechUltra Solutions, the module is aimed at teams negotiating supplier discounts, bulk-purchase rebates, seasonal offers, and one-off pricing agreements. Standard Odoo handles a per-line discount column well; this module covers the cases standard Odoo does not — a single global percentage on the subtotal and fixed-amount rebates — and protects them with role-based access.
Discounts apply consistently across the PO total, the PO PDF report, and the vendor bill. Administrators turn the feature on from Purchase Settings, and access rights decide which users can apply discounts on each order. The module supports Odoo 16, 17, 18, and 19 in both Community and Enterprise editions.
Key features
-
Three discount methods in one wizard
Apply a per-line percentage, a global percentage on the PO subtotal, or a fixed-amount deduction from the total — chosen at the time the buyer raises the order.
-
Discount on all order lines
A uniform percentage discount is pushed onto every product line in the purchase order — useful when a vendor offers a flat percentage on everything you buy from them.
-
Global discount on the subtotal
Apply a single percentage on the PO subtotal without editing each line. Saves time and reduces error on large orders where line-level discounting is overkill.
-
Fixed-amount rebate
Deduct a fixed currency amount from the total purchase value — for vendor rebates, negotiated lump-sum credits, and special pricing agreements that are not expressed as percentages.
-
Automatic total recalculation
Once a discount is applied, the order subtotal, tax, and total recalculate automatically. Buyers see the impact instantly and do not have to redo the maths by hand.
-
Discount shown on the PO PDF
Discount details print on the standard purchase-order PDF report, so vendors and internal teams see the agreed price reduction on the document they actually sign off.
-
Vendor bill flow-through
Discounts on a PO flow straight into the matching vendor bill, keeping accounting and procurement aligned without manual reconciliation.
-
Role-based discount control
Only users with the discount access right can apply discounts on a purchase order — the rest of the team raises orders at list price, which protects margin and prevents unauthorised changes.
-
Toggle from Purchase Settings
Administrators turn the global discount feature on or off from Settings → Purchase, so it can be rolled out company-wide or kept dark in a sandbox.

In Odoo, open Apps, remove the Apps filter, search for “Purchase Global Discount”, and click Install.

Frequently asked questions
-
How is this different from Odoo's standard line discount?
Standard Odoo gives you a Discount column per purchase-order line. This module adds two extra methods on top — a single global percentage on the PO subtotal, and a fixed-amount rebate from the total — and lets you control who can apply them.
-
Do discounts flow into the vendor bill?
Yes. Discounts applied on a purchase order flow into the matching vendor bill automatically, so accounting and procurement stay aligned without manual reconciliation.
-
Does the discount show on the PO PDF for the vendor?
Yes. Discount details are printed on the standard purchase-order PDF report, so the agreed price reduction is visible on the document the vendor actually receives.
-
Can I stop every buyer from applying discounts?
Yes. Discount controls are protected by a dedicated access right. Only users you authorise in Settings → Users can apply a discount; everyone else raises POs at list price.
-
What if I want to turn the feature off later?
An administrator can disable the Purchase Discount option in Settings → Purchase at any time. The Discount button is then hidden on purchase orders.
-
Does the order total update automatically?
Yes. Once a discount is applied, the PO subtotal, tax, and total recalculate immediately so the buyer sees the impact straight away.
-
Which Odoo versions are supported?
The module is published for Odoo 16.0, 17.0, 18.0, and 19.0, in both Community and Enterprise editions.
-
Can I combine the three discount methods on one PO?
Each discount run applies one method — All Order Lines, Global Discount, or Fixed Amount — to the order. Re-running the wizard updates the discount on the order to the new method and value.
