Overview
HAACO (Haji Abdullah Alireza & Co. Ltd.) is one of Saudi Arabia's oldest and most respected business groups. Founded in 1845, it has grown over more than 175 years into a diversified conglomerate. As a distinguished partner of Cosco Shipping, HAACO runs high-volume logistics and supply chain operations across the Kingdom.
When ZATCA's Phase 2 Integration requirements applied, HAACO's problem was not only compliance but volume. Every invoice from a fast-moving logistics operation had to be converted into ZATCA-approved XML, stamped, cleared through the Fatoora platform, and returned without slowing the workflow. And it all had to happen inside a custom-built ERP with no off-the-shelf connector to rely on.
Complyance integrated through a single API and brought HAACO to a near-perfect clearance rate, with no changes to the underlying ERP.
The Challenge
A clearance bar near 99%. HAACO needed consistently high clearance rates on every transaction. Anything less meant rejected invoices and manual rework at a scale their operation could not absorb.
A custom ERP with no ready connector. E-invoicing had to be threaded into an existing bespoke ERP. There was no standard plug-in to install, so the integration had to be built to fit HAACO's system rather than the other way around.
No room to slow down. Each invoice had to be validated, processed, and cleared without interrupting a live logistics workflow.
The Solution
A single API for ZATCA compliance. One documented API converted every invoice into ZATCA-approved XML, with automatic QR code and security stamp generation built in.
A developer-friendly, customizable integration. The integration was tailored to HAACO's workflows and logistics-specific data fields rather than forcing the operation to change shape.
A pre-submission validation engine. Built-in validation caught incorrect tax numbers, missing fields, and invalid codes before anything reached ZATCA, which is what protected the accuracy rate.
Proactive support and a rapid go-live. Hands-on support ran through each stage of implementation.
The Impact
HAACO reached 99.7% accuracy across all e-invoices and cut developer effort by 83%, without replacing or rewriting its custom ERP. Validation was pushed upstream, so errors were caught before submission rather than surfacing as government rejections.
