E-invoicing in Cambodia: Centralized Clearance Model

The Cambodian government has launched its new e-invoicing system, an initiative that marks a significant step toward modernizing and digitizing the country's accounting and commercial processes. This transformation aims to reduce the use of paper, improve tax administration efficiency, and strengthen fiscal transparency.

E-invoicing model in Cambodia

The system follows a centralized clearance model, meaning all electronic invoices must be validated and approved by the tax authority before being considered valid. This not only ensures the authenticity and traceability of invoices but also enables real-time tax oversight by the government.

At the heart of the system is the Cambodia E-Invoicing System (CamInvoice). This official portal serves as the entry and exit point for all e-invoices issued in the country. Through CamInvoice, companies can send and receive invoices, check transaction history, and meet their tax obligations in an automated way.
There are two possible scenarios for invoice transmission:

• If the buyer is registered with CamInvoice: The invoice is delivered automatically through the platform. This ensures the document reaches the recipient immediately, securely, and with official backing.
• If the buyer is not registered: The issuer is responsible for delivering the invoice by alternative means (email, print, etc.). However, submission to the government platform remains mandatory for validation and tax registration.

This new system not only simplifies administrative processes for businesses but also reinforces the fight against tax evasion and supports a stronger, more transparent digital economy.

Implementation Timeline

Throughout 2024, the Cambodian government prepared the legislative framework and launched a pilot project for the B2G sector. The system had a soft launch on December 12, 2024. The system instructs that:

1. Only electronic invoices may be accepted for expense payments in public procurement. An electronic invoice is one issued, validated, and identified as an e-invoice through the Cambodia E-Invoice System.
2. Companies or suppliers must be instructed to register with the Cambodia E-Invoice System if they are not already members.
3. Central entities, central procurement units, and finance units of the ministries will be automatically enrolled in the Cambodia E-Invoice System. Each must appoint a representative to manage its membership and receive e-invoices via the Cambodia E-Invoice Portal. The appointment must be officially communicated to the e-invoice operator by letter.

And for companies or suppliers:

1. Invoices issued to the ministries must be electronic invoices.
2. Suppliers must register with the Cambodia E-Invoice System in accordance with its membership rules and procedures.
3. Electronic invoices may be generated via the Cambodia E-Invoice Portal or any IT invoicing system that is registered, approved, and successfully integrated with the Cambodia E-Invoice System.

Starting 2025

• B2G: Electronic invoicing gradually becomes mandatory for national entities. Invoices must be submitted digitally, validated, and recorded through the Electronic Invoicing System. Furthermore, public entities must notify their suppliers of the obligation to register in the system and operate as active users.

  • As of January 2025, this obligation applies to the budgetary units of the Ministry of Economy and Finance and the Ministry of Environment.

  • As of July 2025, the requirement has been extended to the following ministries: Ministry of Agriculture, Forestry and Fisheries, Ministry of Commerce, Ministry of Industry, Science, Technology and Innovation, Ministry of Education, Youth and Sport, Ministry of Posts and Telecommunications, Ministry of Civil Service. From that point on, these ministries will only be able to accept electronic invoices for payments related to public procurement.

  • As of November 2025, the requirement has been extended to the following ministries: Ministry of Rural Development, Ministry of Mines and Energy, Ministry of Land Management, Urban Planning and Construction, Ministry of Health, Ministry of Public Works and Transport, Ministry of Labour and Vocational Training. It also applies to relevant entities of the Ministry of Economy and Finance, as well as involved companies or suppliers in the Kingdom of Cambodia. 

• B2B: E-invoicing remains voluntary.

Starting 2026

• B2G: E-invoicing becomes mandatory for subnational government entities.
• B2B: E-invoicing becomes mandatory for a defined group of taxpayers.

Starting 2027

• B2G: Mandatory for all government entities.
• B2B: Mandatory for an expanded group of taxpayers.

In the long term, the model is also expected to extend to the B2C sector.

Types of electronic documents

The e-invoicing system applies to two types of invoices: tax invoices and commercial invoices, as well as credit and debit notes. All documents must be exchanged in UBL XML format.

Tax invoices must include some of the following fields:

• Invoice number, issue date, and expiration date
• Buyer’s name, address, and TIN
• List of goods and services (quantity and price)
• Total price per item - excluding taxes
• Other applicable taxes (certain goods/services may be subject to special taxes, public lighting tax, and/or lodging tax), and VAT.
• QR code verified by the Cambodia E-invoice System.

Commercial invoices include information such as:

• Company name, address, contact number.
