How to Apply Discounts at the POS

Vendra POS gives you granular control over discounting — cashiers can apply discounts within limits you define, supervisors can override for larger amounts, and promotional pricelists activate automatically on schedule. This means discounts work fast at the till without letting anyone apply them without appropriate authorisation.

This guide covers both how cashiers apply discounts during a sale and how administrators configure the discount rules in the back office.

Applying a discount during a sale

1. 1
   Select the product lineIn the live POS session, add the products to the order as normal. Tap or click on the specific product line you want to discount to select it.
2. 2
   Tap the Disc button and enter the valueClick the Disc button on the POS numpad. Enter a percentage (e.g., 10 for 10% off) or switch to a fixed amount mode and enter the exact value to deduct. The line total updates immediately.
3. 3
   Proceed to paymentThe discount is applied to that line only. Other lines on the order are unaffected. Complete the sale as normal — the discounted total is what the customer pays and what is recorded in the session report.

Configuring discount limits in the back office

1. 4
   Set maximum discount per cashier roleGo to Point of Sale → Configuration → Settings, then find the Sales section. Enable the Discounts option and set the maximum discount percentage a standard cashier can apply. This caps how much any cashier can discount without triggering an override prompt.
2. 5
   Restrict large discounts with financial securityThe pos_financial_security module adds PIN-based approval for discounts above the cashier's limit. When a cashier enters a discount that exceeds their role's maximum, the system pauses and requires a supervisor PIN before the discount is accepted.
3. 6
   Set up automatic promotional pricelistsGo to Point of Sale → Configuration → Pricelists. Create a pricelist for your promotion — set the product or category, the discounted price or percentage off, and the start and end date. The pricelist applies automatically when the promotion period is active, with no cashier action required.
4. 7
   Supervisor override for larger discountsWhen a cashier needs to give a discount above their limit for a legitimate reason — such as a damaged product, a loyal customer, or a manager decision — the supervisor enters their PIN directly on the cashier's terminal to authorise. The override is logged against the supervisor's account in the session report.

How discounts appear on the receipt

Each discounted line on the printed receipt shows the original price, the discount percentage or amount applied, and the final price paid. If multiple lines have different discounts, each is shown separately. The receipt total reflects the post-discount amount including taxes calculated on the discounted price.
