Finance and tax teams in Saudi Arabia and the United Arab Emirates are dealing with two e-invoicing compliance timelines at the same time. In Saudi Arabia, ZATCA Phase 2 integration is being rolled out in waves across the taxpayer base, pulling thousands of businesses into a mandatory clearance system. In the UAE, the Ministry of Finance published detailed implementation guidance in February 2026 and confirmed the phased go-live calendar.
ERP FOR OIL & GAS
ERP for Oil and Gas in the Middle East: Project Costing, Procurement, and Compliance
Oil and gas businesses operating in the UAE, Saudi Arabia, and the wider Middle East face a combination of operational challenges that no single-purpose software tool can handle. Complex project structures, multi-currency procurement from international suppliers, multi-site operations across field locations and head office, ZATCA e-invoicing compliance, and investor-level financial reporting -these are not independent problems. They are connected challenges that require a connected system.
The Project Costing Problem
In oil and gas project environments, the gap between estimated and actual cost is one of the most monitored metrics in the business -and one of the hardest to track in real time without the right architecture. Each purchase order, service contract, materials delivery, and labour charge needs to land against a project code, a phase, and a cost centre -consistently, from every department, from day one of the project.
When that does not happen, cost reports are always assembled retrospectively -pulling actuals from multiple sources and reconciling them against project budgets that are held somewhere else. By the time the reconciled picture is ready, the project has moved forward, and the decision to act on the cost variance has already been delayed.
Sage X3 addresses this at the transaction level. Every purchase order is raised against a project code. Every supplier invoice is matched against a purchase order and a project. Every delivery is receipted against the right project cost centre. The project’s actual cost position updates as transactions are posted -not when someone has time to assemble the report.
Procurement Complexity: Multi-Currency, Multi-Vendor, Multi-Site
Middle East oil and gas procurement involves international supplier relationships, contracts denominated in multiple currencies, Letter of Credit documentation for high-value imported equipment, and service orders managed across multiple field locations. Each of these adds a layer of complexity that general-purpose procurement tools cannot manage without significant custom configuration.
Sage X3 manages this natively:
- Multi-currency purchase orders with exchange rate management at both order and receipt
- Letter of Credit tracking -linked to purchase orders, monitored for expiry and shipment conditions
- Subcontractor and service order management -tied to project codes and cost budgets
- Multi-site inventory -materials allocated to field locations tracked separately from central warehousing
ZATCA Compliance for Saudi Arabia Operations
For oil and gas businesses with Saudi Arabia operations, ZATCA Phase 2 e-invoicing compliance is not optional. Every invoice issued to a Saudi entity must be submitted to the Fatoora portal in real time, in XML format, with cryptographic stamps. Greytrix Middle East’s proprietary ZATCA integration for Sage X3 handles this automatically -invoice data is extracted from Sage and transmitted to ZATCA without a manual step, with validation status captured inside the ERP.
Why Experienced Implementation Matters More in Complex Industries
An ERP implementation for an oil and gas business in the Middle East is not a standard deployment. Project costing structures, cost centre hierarchies, procurement approval chains, and reporting requirements are specific to each organisation -and getting the design wrong creates reconciliation problems that persist for the life of the system.
Greytrix Middle East begins every oil and gas engagement with a business process design phase -mapping project structures, procurement workflows, and reporting requirements before any configuration begins. The implementation is designed around how the business actually operates, not around default system settings.
Conclusion
For oil and gas businesses in the Middle East, the right ERP is not the one with the most features. It is the one that is configured correctly for your project structures, your procurement complexity, your compliance requirements, and your reporting needs -by a partner who has delivered in this environment before. Greytrix Middle East implements and supports Sage X3 for energy, engineering, and oil and gas businesses across the UAE and Saudi Arabia.
