What an invoice needs to show in Vietnam.
Official invoices in Vietnam are e-invoices registered with the tax authority. An invoice from Openn Invoice shows:
- Your name, address and tax code
- Your customer’s name and address
- An invoice number and the date
- What was sold, with quantity and price
- Any tax as its own line, at the rate you type
- The total, the due date and how to pay
Check with your accountant for your case.

FAQ
Questions from Vietnam.
Can I issue official invoices in Vietnam from Openn Invoice?
Vietnam requires invoices to be issued as e-invoices registered with the tax authority. Openn Invoice is not connected to that system, so in Vietnam use it for quotations, reminders and keeping track of who has paid.
I am not registered for VAT. Can I still use it?
Yes. Leave the Tax code (MST) empty in settings and send invoices with no VAT on them.
Can I bill customers outside Vietnam?
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.

Free covers 5 invoices a month. Pro is 4 $ a month or 35 $ a year, with unlimited invoices, recurring invoices and bank statement matching. Prices for Vietnam are in US dollars and exclude local tax.
