How to invoice in Vietnam
Most Vietnamese invoices are cleared by the tax authority, which returns a verification code. Paper invoices are no longer legally valid: each invoice must be a registered electronic invoice (hóa đơn điện tử) issued in digitally-signed XML. 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.

E-invoicing in Vietnam
E-invoices have been mandatory for enterprises, organisations and business households since 1 July 2022. Since 1 July 2026 the rules are set by Decree No. 254/2026/ND-CP and Circular No. 91/2026/TT-BTC, which replace Decree 123/2020/ND-CP and Decree 70/2025/ND-CP. Invoices are digitally signed XML. Most sellers must use e-invoices authenticated with a tax authority code; enterprises in specified sectors selling directly to consumers (such as electricity, telecoms, e-commerce, supermarkets and transport) may use e-invoices without a code if they meet data-transmission requirements. Under Decree 68/2026/ND-CP, business households and individual businesses with annual VAT-liable revenue of VND 1 billion or more must use e-invoices with a tax authority code or cash-register e-invoices connected to the tax authority.
Invoice Forever can export a structured EN 16931 (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.
