No Thai law sets a service charge. This is the restaurant convention, which we use as a starting number — it is not a statutory rate and it is not enforced anywhere in our product. Change it to whatever your bill says.
- Service charge
- 120.00 baht
- VAT
- 92.40 baht
- Bill total
- 1,412.40 baht
- Each person pays
- 353.10 baht
Service charge on the food, then VAT on both: 1,200.00 + 120.00 + 92.40 = 1,412.40 baht ÷ 4
Rounded to two decimal places, the same way our receipts do it.
Runs entirely on your device. Nothing you type is sent anywhere.
Plainly: our point-of-sale does not add a service charge for you. It separates VAT today; a service charge still has to be put on the bill by hand.
A worked example
Food at menu prices comes to 1,200 baht. A 10% service charge adds 120 baht, and 7% VAT on the two together adds 92 baht more, so the real bill is 1,412 baht — meaningfully above the menu price, which is what the «++» on a menu is warning you about.
How to use it
Enter the food and drink at menu prices, before anything is added, then the number of people. The service charge starts at ten per cent, which is a restaurant convention rather than a law — change it to whatever your venue actually charges. The conventional order is the service charge on the menu subtotal first, then VAT on both together. Some venues charge VAT on the food alone, so there is a switch for that. The VAT rate this page uses is read from the rate table we keep, with a link to the Revenue Department notice.

See the restaurant systemFrequently asked questions
- Is a service charge required by law?
- No. No Thai law requires or forbids a service charge — it is a convention each venue chooses. VAT is different: it is a statutory tax with a published notice behind it. This page keeps the two visibly apart.
- Does VAT apply to the food only, or to the service charge too?
- The common «++» bill applies the service charge first and then VAT on both together, but some venues charge VAT on the food alone. Check the receipt and pick the matching option on this page.
- Where does the VAT rate on this page come from?
- From the rate table we keep, with the date it took effect and a link to the Revenue Department notice. If we cannot read that table, this page shows no calculator at all rather than guessing the rate.
