An InvoiceNow integration does three jobs: send outbound invoices to customers on the network, transmit the data IRAS requires, and receive supplier invoices back into accounts payable. Most projects plan for the first, are told about the second, and forget the third.
Singapore, the UAE and Oman all run on Peppol. An integration built for one is most of the way to the others — the work is in the national specification, not the plumbing.
The exchange model, provider-to-provider delivery and status handling carry over.
Each country adds its own rules on top of Peppol International. That is a mapping, not a new project.
IRAS in Singapore, the FTA in the UAE, the OTA in Oman — each with its own scope and timing.
Your own UEN-based Peppol ID, and your customers’ where they are on the network, held on the master record.
Standard-rated, zero-rated and exempt supplies mapped cleanly to the PINT SG tax categories.
Credit notes linked to the invoices they correct, so they validate and reconcile on both sides.
Supplier e-invoices arrive as data. AP needs a matching and approval flow, not a mailbox.
Delivery and rejection statuses returned to the invoice in the ERP, so finance sees failures without leaving it.
Groups with several Singapore entities need each one addressed correctly on the network.
