How to invoice in Vietnam
A compliant Vietnamese invoice must be a registered electronic invoice (hóa đơn điện tử) issued in digitally-signed XML and cleared by the General Department of Taxation, which returns a tax-authority verification code — paper invoices are no longer legally valid. It must show the seller's and buyer's names, addresses and tax codes (MST), an invoice serial and number, line-item descriptions, quantities, unit prices, the VAT rate and VAT amount, and the seller's digital signature.

VAT & reverse charge
For cross-border work, the right wording matters. Invoice Forever offers ready-made Vietnamese VAT notes such as:
- VAT charged at the applicable Vietnamese rate — standard 10%, with a temporary 8% rate on most eligible goods and services through 31 December 2026 (Resolution 204/2025/QH15).
- Exported goods and services are zero-rated (0% VAT) where the required contracts, customs declarations and non-cash payment documentation are met.
- Payments to foreign contractors may be subject to Foreign Contractor Tax (FCT) withheld by the Vietnamese payer.
E-invoicing in Vietnam
Mandatory for all enterprises, organisations and registered business households since 1 July 2022 under Decree 123/2020/ND-CP, updated by Decree 70/2025/ND-CP effective 1 June 2025. Invoices are issued as digitally-signed XML, cleared in real time (or reported same-day) by the General Department of Taxation, and carry a tax-authority verification code; qualifying retail and F&B businesses and business households over VND 1 billion turnover must connect POS cash registers to the GDT.
Invoice Forever can export a structured EN 16931 / Peppol BIS (UBL) e-invoice alongside the PDF (beta) — the format most of these mandates are built on. You still send it via your own access point, and some countries require their own national format.
Verified 23 July 2026 against the source. E-invoicing rules are changing quickly, so always confirm the current position with the General Department of Taxation (GDT) under the Ministry of Finance before you rely on it. This page is general guidance, not tax advice.
Payment terms in Vietnam
B2B terms typically run 15–30 days and are settled by bank transfer. Note that any single invoice of VND 20 million or more must be paid by non-cash bank transfer to claim input VAT and a corporate income tax deduction.
