Cambodia has officially launched its centralized e-invoicing system, CamInvoice, marking a major step forward in the country’s digital transformation agenda. The new system is designed to modernize tax administration, reduce paper use, and improve fiscal transparency through real-time validation of electronic invoices.
Following a centralized clearance model, all e-invoices must be validated by the tax authority before being legally recognized. CamInvoice handles this process, verifying invoices via multiple checks—including XML structure and tax rule validation—before storing them securely using blockchain technology.
The system soft-launched in December 2024 for B2G transactions, with mandatory use for national government entities starting in 2025. B2B use remains voluntary for now but is expected to become mandatory for select businesses in 2026, and to expand further—including B2C—by 2027.
Two types of documents are supported: tax invoices and commercial invoices, both in UBL XML format and featuring QR code verification.
Cambodia’s General Department of Digital Economy is encouraging early adoption, noting the platform’s scalability, flexibility, and potential to streamline compliance and auditing processes for businesses of all sizes.
