Discounts

Biller supports two kinds of discount, applied to a whole bill (not individual items): a percentage off (e.g. 10% off) or a flat amount off (e.g. Rs. 50 off). You first define named discounts for your outlet, then apply one from the billing screen when you need it.

Creating a discount

1. Go to Outlet in the admin side bar.
2. Under Discounts, tap New Discount.
3. Fill in:
   • Discount Name -- e.g. "Festive 10% off", "Flat 50 off". This is the name that shows up on the bill and the printed/customer receipt once applied.
   • Type -- Percentage or Flat amount.
   • Value -- the percentage (e.g. 10 for 10%, capped at 100) or the flat rupee amount (e.g. 50).
   • Active -- only active discounts can be applied to a bill; toggle one off to retire a past promotion without deleting its history.
4. Tap Add.

Each discount you create appears as a card, showing its name, value and whether it's active. Tap Update on a card to change it, or to delete it.

Applying a discount to a bill

1. Open a bill on the billing screen.
2. In the bill summary, next to Discount, tap Apply (or Change if one is already applied).
3. Pick one of your outlet's active discounts, or No discount to clear whichever one is currently applied.
4. Tap Apply.

The bill's total updates immediately -- tax is computed on the post-discount amount, matching how the total is charged. Once applied, a discount is locked in for that bill: editing or deleting the discount definition afterwards (from Outlet settings) never changes a bill's total retroactively.

Notes

• Discounts apply to the whole bill, not individual items -- there's no per-item discount today.
• A discount can never take a bill below Rs. 0 -- an oversized percentage or flat amount is automatically capped at the bill's subtotal.
• Applying a discount is available to admins, cashiers and waiters; only admins can create, edit or delete discount definitions.
• The discount line shows up on every receipt surface -- the billing screen, the customer's digital bill, the printed receipt and the thermal print-out -- consistently.
