Service charge, VAT and how a bill adds up

Two rates decide what a customer pays on top of the goods, and both start at zero. Until you set them, a bill is the items plus delivery and nothing else.

1. Open Settings, then Receipts and tax under Money.
2. Say who you are: legal name, PAN/VAT number and phone. All three are optional and all three print at the top of every bill. Filling in the PAN also starts your numbered tax invoice series, see Tax invoice numbers.
3. Set your VAT rate. VAT in Nepal is 13%. If you are not VAT registered, leave it at 0 and no VAT line appears anywhere.
4. Set your service charge if you take one, usually 10% in a restaurant. Leave it at 0 and no service line appears.

Two other things live on this same page: the address customer replies come back to, see Where customer replies land, and the width of the roll in your printer, see Print on a 58mm or 80mm roll.

The order the sums happen in

It matters, because each step feeds the next.

• The subtotal is the items.
• A promo discount comes off first.
• Service charge is worked on the discounted subtotal.
• VAT is worked on the discounted subtotal plus the service charge, so the service charge is taxed too.
• Delivery is added last, after VAT, so a delivery fee is never taxed.

A worked example on a bag of 1,000 with a 10% code, 10% service and 13% VAT: 100 off leaves 900, service adds 90, VAT on 990 adds 129, and a delivery fee of 100 brings it to 1,219. Everything is rounded to whole rupees.

The same figures everywhere

Your rates follow the sale wherever it is rung: the storefront checkout, a counter order you type on the board, the printed receipt and the customer's emailed one all use them, so no two copies of a bill disagree. A counter order takes no promo code, so its total starts at the subtotal.

Change a rate and only new orders follow it. The service and VAT on an order are stored with that order, so an old bill still totals what the customer actually paid, however many times you reprint it. What you collected is added up for you month by month, see Check the month's takings.
