Tax ID
The Tax ID is 13 digits. Tax invoices also say whether they come from the head office or a branch; add that to your address. With it saved, your invoices are titled “Tax Invoice”. Without it they are a plain “Invoice”.

What a Tax Invoice needs to show in Thailand.
The Revenue Code lists what a Tax Invoice carries:
- The words “Tax Invoice”
- Your name, address and Tax ID, and head office or branch number
- Your customer’s name and address, and their Tax ID if VAT-registered
- A serial number and the date of issue
- The name, type, quantity and value of the goods or services
- The VAT as a separate amount
Check with your accountant for your case.

FAQ
Questions from Thailand.
Does Openn Invoice make a proper Tax Invoice for Thailand?
Yes. Add your Tax ID in settings and each invoice is titled “Tax Invoice”, with VAT worked out line by line at the rate you pick (7% and 0%) and totals in Thai baht. What it has to show in Thailand is listed on this page. Check with your accountant for your case.
Does it file my VAT return?
No. Openn Invoice makes invoices and shows who has paid. It does not file returns or keep full accounts. Paid plans include a tax report and CSV downloads to hand to your accountant.
I am not registered for VAT. Can I still use it?
Yes. Leave the Tax ID empty in settings and send invoices with no VAT on them. They are titled “Invoice” instead of “Tax Invoice”. VAT registration is required once income passes ฿1.8 million a year.
Can I bill customers outside Thailand?
Yes. Pick the customer’s country and currency on the invoice. A customer abroad is billed as an export, with no VAT added. You see the reason on the invoice before you send it.
What does it cost in Thailand?
Free covers 5 invoices a month. Pro is $6 a month or $49 a year, with unlimited invoices, recurring invoices and bank statement matching. Prices for Thailand are in US dollars and exclude local tax.
Are the app and the invoices in Thai?
Not yet. The app and the printed labels on invoices are in English. What you type, such as item descriptions, notes and terms, can be in any language.
