ERP Integration.
Compliance-grade ERP integration for ZATCA Phase 2, UAE FTA Peppol PINT AE, and emerging GCC e-invoicing mandates. Six platforms. Enterprise architecture.
What GCC e-invoicing demands from ERP integration.
ZATCA Phase 2 is not a simple API connector. It requires cryptographic key management, invoice chain hashing, a real-time clearance API integration, and a rejection handling workflow — all embedded inside the ERP's invoice generation process.
ClayDesk builds ERP integrations that treat these requirements as engineering problems, not procurement decisions. The signing key stays on enterprise-controlled infrastructure. The clearance workflow is implemented natively inside the ERP. The invoice chain hash is computed correctly across multi-server ERP environments. The rejected invoice queue is accessible to the finance team inside the ERP — not in a vendor portal.
This is the architecture that produces compliance resilience. It is what we build on every platform we support.
How we build.
Keys stay on-premise
The ECDSA private key used for ZATCA signing is generated and stored on enterprise-controlled infrastructure — not in a vendor key management service. This is the cornerstone of compliance infrastructure ownership.
Native ERP integration
The clearance workflow is built inside the ERP — as an ABAP class on SAP, as an Oracle extension, as a D365 plugin. Not as an external middleware layer that the ERP calls through a queue. Native integration means lower latency, better error visibility, and no middleware to maintain.
Shadow mode before enforcement
Every integration includes a shadow mode phase — the clearance workflow runs in parallel with invoice release, logging results without blocking. Go-live to enforcement mode only after a clean shadow mode run. This is non-negotiable on our projects.
Data pipeline as a by-product
The structured invoice data that flows through the compliance integration is also written to an enterprise data warehouse. The compliance implementation becomes the foundation of the Pillar II data pipeline — not a separate project.
