Expense tracking in Thailand for foreign residents
Updated 26 September 2026
1. Bank and PromptPay payments
Thai banking apps show a slip after each payment, including PromptPay payments. Save your slips to your photos, and Slip Tracker fills in the amount, the date and time, who you paid, and the reference number.
It knows the slips from K PLUS, SCB EASY, Krungthai NEXT, Bangkok Bank and TrueMoney Wallet. Other banks' slips may not be read yet. See which slips it reads.
Slip Tracker never connects to a bank. See how to import saved slips on Android, step by step.
2. The app in English
Slip Tracker uses your phone's language if it is English, Thai, Japanese, Korean, German or French. For any other language, it uses English. You can change it in Settings.
3. Slips with Thai writing
Many slips have Thai writing, such as a shop's or a person's name. On Android, the app reads the English writing and the QR code, but it can't read Thai writing yet. When a name is in Thai, the app asks you to check that slip, and you type the name.
On Android, slips in English work best. If you change a category, Slip Tracker can remember it for that shop next time.
4. Cash
Street food, markets and taxis are often paid in cash, and cash leaves no slip. Add those by hand, so your total is complete.
5. Totals in baht
Slip Tracker counts in baht and doesn't convert other currencies.
6. A month, for example
Here is a sample month on Android. Home shows what you spent so far this month, compared with the same days last month, and your top categories.
Insights shows the highlights and every category and shop. Want a number to aim for? Set a monthly spending guide, and Slip Tracker shows whether you are on track. It never stops a payment.
7. Changing phones
Your transactions are kept on your phone, not in an online account, and they don't move to a new phone by themselves. Before you switch, open Settings, then Backup & Restore, and tap Create backup file. Keep the file somewhere you can reach from the new phone.
On the new phone, install Slip Tracker, open Backup & Restore, and tap Restore from a file. With Premium, you can also export your spending as CSV, Excel or PDF.
8. Common questions
Can I use Slip Tracker in English?
Yes. It uses your phone's language if it is English, Thai, Japanese, Korean, German or French, and English for any other language.
Can it read slips in Thai?
On Android, not fully yet. It reads the English writing and the QR code on a slip, and you type the parts written in Thai.
Does it convert other currencies?
No. Slip Tracker counts in baht and doesn't convert other currencies.
How much does it cost?
It is free to start: 100 scans in your first 30 days, then 50 each month. Premium adds unlimited scans, month-by-month trends and more ways to export.
