What is CamInvoice?

CamInvoice operates on a real-time clearance model where every invoice must pass through the GDT platform before becoming legally binding. The process begins when a seller generates an invoice in UBL XML format and submits it to CamInvoice via API or web portal. The GDT system validates the invoice structure, tax calculations, and seller registration status. Upon successful validation, CamInvoice assigns a unique cryptographic reference number and returns the cleared invoice to the seller. The seller then transmits the cleared invoice to the buyer. This real-time clearance approach gives the GDT immediate visibility into economic transactions, enabling automated VAT reconciliation and significantly reducing tax fraud opportunities.

The GDT has structured CamInvoice adoption in three phases to allow businesses adequate preparation time. Each phase expands the mandate to a broader segment of the taxpayer base, ultimately achieving universal electronic invoicing coverage across Cambodia's formal economy. Businesses approaching their mandatory compliance date must ensure their accounting systems can generate UBL XML invoices, establish API connectivity with the CamInvoice platform, and train staff on the new invoicing workflows. Early preparation is critical as non-compliance carries financial penalties and potential business license implications.

CamInvoice creates a transformative opportunity for supply chain finance in Cambodia. Because every invoice is validated and timestamped by the GDT, cleared CamInvoice records serve as trusted, tamper-proof proof of trade. Financial institutions can use these verified invoices as the basis for invoice financing, factoring, and supply chain credit products. This is particularly significant for Cambodian SMEs that traditionally lack the documentation and credit history needed to access trade finance. A GDT-cleared CamInvoice record provides the verifiable receivable data that banks need to extend working capital financing, potentially unlocking billions in previously inaccessible credit for small businesses.

CamFinTech navigates the SP-accreditation pathway and CamInvoice readiness assessment, and runs the compliance programme that keeps enterprises approved. Our work covers ERP-system gap assessment, UBL XML mapping requirements, GDT-side certification sequencing, and staff training for the transition to mandatory e-invoicing. The technical build itself — middleware that converts internal invoice data to UBL XML, API integration with the CamInvoice platform, lending-platform architecture that consumes verified CamInvoice records via CamDX for supply-chain finance — is coordinated with accredited Service Providers. CamFinTech is fee-only and never holds client funds.
