MxiPOS e-invoice integration

E-invoicing in Vietnam

Create an e-invoice from an MxiPOS order after checkout, without entering the sale again in your invoicing platform.

All e-invoice fees are collected by the invoice provider. MxiPOS provides the integration at no charge and charges no connection fee.

What is an e-invoice?

An electronic invoice is the official tax invoice used by businesses and household businesses when selling goods or services in Vietnam. It is created through an e-invoice service platform, and the relevant data is transmitted to the tax authority as required.

Who can use POS-generated e-invoices?

Restaurants, cafés, retailers, and supermarkets using a POS can use an e-invoice generated from a cash register (Hóa đơn điện tử khởi tạo từ máy tính tiền) where that option applies, starting from the checkout order.

How does MxiPOS issue e-invoices?

MxiPOS connects to an e-invoice provider and uses checkout orders for invoicing, reducing repeated entry of items, amounts, and order details.

  1. 01

    Customer checks out

  2. 02

    MxiPOS creates the order

  3. 03

    Submit invoice data securely

  4. 04

    Provider processes the invoice

  5. 05

    Transmit securely to the tax authority

The MxiPOS × FAST setup uses HSM for automatic invoice signing; the e-invoice provider handles the subsequent data transmission.

Current regulatory context: Decree 254/2026/NĐ-CP, effective 1 July 2026, sets out the framework for e-invoices and POS-generated e-invoices. The applicable method depends on the merchant's circumstances. Read the government decree ↗

What do you need to get started?

Vietnamese businesses

You will usually need:

  • Company or household business registration details
  • Tax identification number (MST)
  • Legal representative or household business owner's details
  • Citizen ID (CCCD) or personal identity details
  • Mobile number and email address
  • Digital signature
  • E-invoice provider account

Once the details are ready, you can submit an e-invoice usage registration to the tax authority through a provider such as FAST or MISA. After acceptance, invoices can be issued under the approved method.

Foreign-invested enterprises (FDI)

In addition to applicable business and tax details, you will usually need:

  • Enterprise Registration Certificate (ERC)
  • Investment Registration Certificate (IRC), if applicable
  • Foreign legal representative's passport
  • Legal representative's contact and identity details
  • Digital signature and e-invoice service account

If the legal representative is a foreign national, the tax authority may request further identity verification.

Note: A Work Permit, visa, and Temporary Residence Card (TRC) relate to a foreign national's work and residence in Vietnam. They are not universal requirements for opening an e-invoicing account.

MxiPOS can help connect the systems, configure access, and test invoice issuance.
