Can ERP and POS vendors add CamInvoice without rebuilding their products?
An answer for Cambodian software providers weighing one shared integration layer against a separate connector in every customer deployment.
Short answer
Yes, a vendor can keep its ERP or POS workflow and place an integration layer beside it. For a Cambodia POS e-Invoicing integration, the source product still owns sales and accounting records; the layer handles the agreed invoice mapping, submission, response and support trail. Whether a particular vendor can connect to the official system depends on onboarding and testing, not on this page.
Official context: GDDE, Ministry of Economy and Finance
What to remember
- Design one documented boundary between the product and the integration layer.
- Do not promise an official connector before the interface is tested.
- Give support staff a way to see each invoice outcome.
What stays inside the product
The ERP keeps customer records, approvals and accounting. The POS keeps the sale and the cashier flow. Export a stable invoice event with a source identifier rather than copying tax rules into every screen.
GDDE has publicly discussed integration with accounting system providers. That confirms the relevance of software-vendor integration, but it does not confer the same status on every prospective partner.
What the shared layer needs to own
Define field mapping, validation, document correlation and response handling once. Then test each product version against that contract. A partner also needs clear ownership when a buyer ID is wrong or an invoice stays pending.
For a multi-customer rollout, decide who maintains the mapping when official requirements change and who answers the merchant's first support call.
Questions before implementation
- Which ERP or POS versions are actually in use?
- Can the product expose a stable invoice event and accept a status update?
- Who owns onboarding, testing and customer support?
Quick questions
Is middleware the same as an official CamInvoice connector?
No. Middleware is the integration design. Official access and tested connectivity are separate project facts.
Can a vendor offer this under its own brand?
That is a commercial and support arrangement to agree with EazLink; it does not change the official onboarding requirements.
