E-Invoice Integration Specialist

E-invoice infrastructure.
Any country. Any model.

I build e-invoicing integrations across Peppol C4 and C5 markets — Singapore InvoiceNow (IRAS C5), UAE eInvoicing (DCTCE / PINT AE) — and direct-clearance mandates like Malaysia's IRBM MyInvois. Personally built. Not just advised on.

50+ Peppol Countries
2×C5 SG IRAS · UAE FTA
3 Tax Authorities Integrated

What I Build

One service. Three country models.

Every e-invoicing mandate fits one of three architectures. I have built production integrations in each — so wherever your next market is, the model is already familiar.

peppol_c4.cfg
Peppol · 4-Corner

C4 — Network Exchange

The classic Peppol model: invoices flow between trading partners through certified Access Points. No tax authority in the loop.

  • Access Point & SMP/SML setup
  • BIS 3.0 / PINT document mapping
  • AS4 messaging, MLR handling
  • EU · Australia/NZ · Japan markets
peppol_c5.cfg
Peppol · 5-Corner

C5 — Tax Authority CTC

Peppol exchange plus a fifth corner: the tax authority receives invoice data continuously. The model regulators are converging on.

  • Singapore — IRAS C5 GST transmission
  • UAE — FTA via DCTCE, Tax Data Document
  • PINT SG / PINT AE specialisations
  • ASP / Access Point integration
direct_clearance.cfg
Non-Peppol · National API

Direct Clearance

No Peppol network — invoices clear directly through the tax authority's own API before they are valid. Each country builds its own.

  • Malaysia — IRBM MyInvois API
  • UBL 2.1, X.509 signature, all 5 doc types
  • 72-hour rejection & cancellation flow
  • PINT MY alignment on the horizon
About This Practice

Not a consultancy.
One specialist who has built it.

I have personally implemented Peppol Access Points end-to-end — IMDA-certified AP onboarding, AS4 messaging protocol, SMP/SML registration, Peppol BIS 3.0 and PINT SG document mapping, and the pioneering C5 IRAS GST data forwarding pipeline.

I have also personally implemented Malaysia e-Invoice end-to-end — the complete IRBM / MyInvois API for service providers, X.509 digital signature, UBL 2.1 mapping, and all 5 document types.

The same architecture now lands in the UAE as DCTCE — a Peppol 5-corner model with PINT AE documents and Tax Data Document reporting to the FTA. This is not advisory at arm's length. This is production implementation experience.
