1. On the billing screen, look at the summary panel on the right (or tap the bottom total bar on mobile).
2. Next to the Discount row, click Add discount.
3. The discount window opens, displaying the bill's full price, current total, and calculation modes.

Choose the mode that fits your conversation with the customer:

• Final amount: Enter the exact total amount you want the customer to pay (e.g. type 500 for a ₹535 bill).
• ₹ off: Enter a flat rupee amount to subtract from the bill (e.g. type 50 to give ₹50 off).
• % off: Enter a percentage discount (e.g. type 10 for a 10% discount).

As you type, the preview immediately displays the discount amount, the discount percentage badge, and the new total to be collected. Click Apply discount.

When goods sold by weight or taxes leave fractional paise on the bill (such as ₹487.40):

• Click Drop paise to discard the 40 paise and round the bill down to ₹487.
• Click Round up to round the bill up to ₹488.

One tap cleans up the bill so cash transactions are fast and hassle-free.

Unlike systems that simply subtract a lump sum at the bottom:

1. EzDukkan shares the discount proportionally across all eligible items on the bill.
2. Prices are resolved in whole rupees first wherever possible, so customer receipts look clean and natural (e.g. ₹240 instead of messy decimals like ₹240.38).
3. Each item's individual discount column updates to show its share of the discount.

If a customer returns an item from a discounted bill:

1. Open the invoice details and click Return Items.
2. EzDukkan calculates the refund based on the discounted rate the customer actually paid for that specific item, not its full original price.
3. Your shop accounts and cash registers remain completely protected against over-refunding.
