Instruction
Instruction video: E-Invoice common
This module provides the provider-agnostic backbone for Vietnamese e-invoicing. Once a provider module is installed alongside it - Viettel S-Invoice, VNInvoice (VNIs) or MISA meInvoice - every provider is configured, issued, tracked, adjusted, replaced and cancelled from the same unified E-Invoice interface described below, instead of one separate screen per provider.
1. Configure the Vietnam E-Invoicing settings.
- Go to Accounting > Configuration > Settings and open the Vietnam E-Invoicing section.
- Select the e-invoice Provider for the company. The provider-specific connection fields appear underneath once a provider is chosen, so you only see the settings that apply to you.
2. Use the unified E-Invoice menu.
- A single E-Invoice menu now groups every e-invoice configuration and operation - serials, templates, types and the list of issued e-invoices - replacing the former per-provider menus.
3. Fill in e-invoice information on the customer invoice.
- Open a customer invoice. The E-Invoice notebook tab gathers, in one place, the status and identifiers, the correction information, the provider sub-group and the generated documents - no matter which provider issued the invoice.
4. Track e-invoice status across every provider.
- On the customer invoice list, use the E-Invoice Status filter and group-by to see, in one normalized view, which invoices are still to issue, issued, adjusted, replaced, cancelled or in error - regardless of the underlying provider.
5. Adjust or replace instead of cancelling an issued e-invoice.
- An already-issued e-invoice can no longer be simply cancelled, regardless of when it was issued. The system blocks the cancel action and guides you to issue an adjustment or a replacement e-invoice, keeping your books compliant.
Legal basis
Vietnamese e-invoicing runs under two instruments in force from 1 July 2026:
- Decree 254/2026/ND-CP (Nghị định 254/2026/NĐ-CP), which repeals Decree 123/2020/ND-CP in full, Article 1 of Decree 41/2022/ND-CP, and Decree 70/2025/ND-CP in full.
- Circular 91/2026/TT-BTC (Thông tư 91/2026/TT-BTC), which ends Circular 32/2025/TT-BTC.
Three of their provisions shape how this module behaves.
A written agreement comes before an adjustment or a replacement. Where the buyer is an economic organisation, another organisation, a business household or an individual trader, the seller and the buyer draw up a written agreement identifying the error before the corrected e-invoice is issued; a private individual buyer receives a notice instead. Note that an individual trader counts as a business buyer here, not as a private individual. This requirement applies only to a point-b) correction; a point-a) error is notify-only and never produces a corrected e-invoice. No written agreement is required when the seller transfers e-invoice data through the E-Invoice Data Summary Table, when it transfers transaction-detail data through the Transaction Detail Information Table, or for goods sold on an e-commerce platform or another digital platform. Two settings tell the module which of those applies to you. Set E-Invoice Data Transfer Method in the Vietnam E-Invoicing settings to record how your company reports to the tax authority - it is your standing registration, so it applies to every invoice until you change it. Tick Sold on an E-Commerce or Digital Platform on the invoice itself for a sale made through a platform, because the same seller trades on and off a platform on the same day. When one of them applies the wizard proceeds without an agreement name; otherwise it asks for one and will not continue until you supply it. (Point b.2, Clause 1, Article 10, Circular 91/2026/TT-BTC, whose closing paragraph refers to Points a.1 and a.2, Clause 3, Article 16, Decree 254/2026/ND-CP.)
An issued e-invoice is corrected, never cancelled. Correction is by adjustment or by replacement, whenever the invoice was originally issued - an invoice first issued under Decree 51/2010/ND-CP, Decree 04/2014/ND-CP, Decree 123/2020/ND-CP, Decree 70/2025/ND-CP or Circular 32/2025/TT-BTC is corrected the same way (Clause 2, Article 24, Circular 91/2026/TT-BTC). This is why, from 1 July 2026, the cancel action is blocked once an e-invoice has been issued. Before that date the cancel action behaves as it did, because an earlier Decree provided for it; what changed on 1 July 2026 is the law, not your past records. Clause 1, Article 10 enumerates every route open to a seller who finds an issued e-invoice wrong - notify the buyer, issue an adjustment, or issue a replacement - and cancellation is not among them (Clause 1, Article 10, Circular 91/2026/TT-BTC).
A replacement e-invoice carries the prescribed notation. The replacement states Thay thế cho hóa đơn Mẫu số... ký hiệu... số... ngày... tháng... năm, with the date written day, then month, then year. The module fills this in for you from the invoice being replaced. (Point b.2, Clause 1, Article 10, Circular 91/2026/TT-BTC.)
Keep the written agreement available: the tax authority, or another competent state agency, may ask the seller to produce it.
