Apply the whole deal in one click not line by line
Discount On Purchase Order turns a negotiated vendor concession into a single order-level action — live preview, per-vendor presets, and a full audit trail, all flowing through Odoo’s native purchase totals.
Odoo forces buyers to open every purchase order line and key in a discount one product at a time. For orders with dozens of lines that means slow manual entry, transcription errors, and no single record of what was actually negotiated with the vendor.
Enter one percentage or fixed amount and apply it to the whole order in a single click. The concession is redistributed as a uniform per-line discount that flows straight through Odoo’s native tax and total calculation — nothing to reconcile by hand.
Everything a buyer needs to negotiate and record a deal
Every capability below is implemented in the module.
Order-Level Discount In One Action
Apply a percentage or fixed-amount discount to an entire purchase order without touching a single line manually.
Live Before/After Comparison
Watch the undiscounted total, the projected total, and your savings update in real time as you type — before you even click Apply.
Discount Reflected In Native PO Lines
The concession is written straight into Odoo’s own per-line discount field, so tax and total calculations stay accurate with zero extra logic.
Smart Redistribution Across Lines
A fixed-amount concession is converted into the exact uniform percentage that reproduces the negotiated total across every product line.
Visual Highlight Of Discounted Lines
Every line carrying a discount is visually marked on the order, so buyers can confirm at a glance exactly what changed.
Reusable Discount Templates
Save a named discount, such as “Wholesale Supplier — 5%”, and apply it with one click, optionally scoped to a specific vendor.
One-Click Copy To Vendor’s Other RFQs
Replicate a negotiated discount onto every other draft or sent order from the same vendor without re-entering it.
Full Audit Trail Of Every Discount
Every applied discount records who applied it, when, and the original vs. discounted totals, ready for vendor reconciliation.
Permission-Gated Access
Restrict who can apply order-level discounts through a dedicated group tied to Purchase Settings.

See it in action
From live preview to the audit trail, see the whole workflow.
The discount panel sits right on the purchase order: choose percent or fixed amount, apply, and watch the highlighted lines update instantly.
Every order keeps its own Discount History page, a read-only record of every concession ever applied to it.
Save the current discount as a named template in one click, ready to reuse on the next order from the same vendor.
Reusable, optionally vendor-scoped discount templates keep standing terms one click away.
Each template records its type, value, and vendor scope so it can be applied instantly.
A company-wide Applied Discounts log lists every concession, who applied it, and the before/after totals.
Drill into any log entry for the full detail behind a single applied discount.
An optional Purchase Settings toggle restricts order-level discounting to a dedicated permission group.
Frequently asked
Does this replace Odoo’s pricelists?
No. Pricelists remain the right tool for standing catalog prices. This app is built for ad-hoc, order-level concessions negotiated with a vendor for a specific purchase order, with no pricelist configuration required.
How is a fixed-amount discount distributed across lines?
The fixed amount is converted into the exact uniform percentage that reproduces the negotiated total across every product line, so per-line receipts and vendor invoices stay consistent.
Can anyone apply an order-level discount?
By default any purchase user can. An optional Purchase Settings toggle restricts the action to a dedicated permission group when you need tighter oversight.
Is there a record of who applied a discount and when?
Yes. Every applied discount is logged with the applying user, the timestamp, and the original vs. discounted totals, both on the order itself and in a company-wide audit log.
