ERP to Zoho ZATCA Compliance Integration

Designed and built an ERP-to-Zoho API integration for ZATCA e-invoicing compliance — any invoice created on the company ERP automatically passes through Zoho and submits to the ZATCA portal without manual steps.

ZATCA e-invoicing

Challenge

What needed to move

Saudi Arabia's ZATCA regulation requires all company invoices to be submitted electronically. The company ERP generated invoices but had no automated path to the ZATCA portal.

Company ERP as invoice source of record

ERP API for extracting invoice fields and details

Zoho Deluge code for payload transformation and formatting

Zoho integration layer for ZATCA portal submission

Solution Architecture

How the system was shaped

The implementation focused on clarity, repeatability, and operational confidence.

Analyzed the company ERP API to identify invoice fields required by ZATCA.

Wrote Zoho Deluge code to receive ERP invoice data and transform it to ZATCA format.

Wired the ERP API trigger so every new invoice automatically flows into Zoho.

Tested the full pipeline end-to-end for ZATCA compliance accuracy.

Outcomes

Every ERP invoice is automatically submitted to ZATCA without any manual effort.

Company meets Saudi Arabia e-invoicing compliance requirements.
