POS Global Discount
Apply percentage or fixed-amount discounts on entire POS orders in seconds — with built-in max-discount controls, cashier validation, and a clean numpad popup.
Standard Odoo POS — What's Missing
- No built-in option to apply a discount on the entire POS order at once
- Fixed-amount discount on orders is not supported out of the box
- No way to set a maximum discount percentage or amount per shop
- Cashiers can only discount individual lines — tedious for large orders
- No validation to prevent excessive or unauthorized discounts
- No popup UI — cashiers must manually edit each order line
What This Module Solves
- One-click global discount button inside the POS actions menu
- Choose between percentage discount or fixed amount per transaction
- Configure maximum allowed discount per POS shop from backend settings
- Automatic discount line created on the order — no manual editing
- Real-time validation with error notification when limits are exceeded
- Modern numpad popup — fast, touch-friendly, works on any screen size
Global Discount Button
A dedicated Global Discount button appears in the POS actions menu whenever the feature is enabled from settings.
Percentage Discount
Enter a percentage value and the module automatically calculates the discount amount based on the order subtotal.
Fixed Amount Discount
Enter an exact currency amount to discount from the order total. Ideal for vouchers or manager-approved discounts.
Max Discount Controls
Set a maximum discount percentage and maximum amount per POS shop. Cashiers are blocked from exceeding these limits.
Modern Numpad Popup
A clean popup lets the cashier pick the discount type and enter a value — touch-optimized for tablets and POS terminals.
Automatic Discount Line
Discount is added as a negative order line using a configurable discount service product. Works with receipts and reports.
Replace & Reapply
If a discount is already applied, confirming a new value removes the old line and adds the updated one automatically.
Per-Shop Configuration
Each POS configuration can have its own discount product, max percentage, and max amount — full control across multiple shops.
Error Notifications
If a cashier enters a discount exceeding the configured limit, an instant error notification appears inside the popup.
Configure in Backend
Enable Global Discount in POS settings, set a discount product, and define max discount limits.
Add Products to Order
Open POS, add products to the order — the discount button appears in the actions menu.
Click Global Discount
Tap the button, select Percentage or Fixed Amount, enter the value on the numpad.
Confirm & Pay
Confirm the discount — it's instantly added as an order line. Proceed to payment as normal.
| Setting | Description |
|---|---|
