What Is Oman e-Invoicing (Fawtara)?
Fawtara is the Oman Tax Authority's national e-Invoicing program. It requires VAT-registered businesses to issue invoices in structured digital formats and exchange them through accredited Service Providers, using the Peppol network.
The rollout is already underway, starting with large taxpayers in 2026 and expanding to all VAT-registered businesses by 2027. Once your business is notified, there is no permanent exemption. Preparing early means your invoicing, accounting, and approval workflows are tested and compliant before the deadline — not rebuilt under pressure after it.
Phased Deadline Schedule
OTA notifications will detail your mandatory transition dates.
Why Choose CodeStack?
Most businesses in Oman don't run identical operations, so they shouldn't run identical software. CodeStack builds custom ERP systems shaped around how your business actually invoices, approves, and collects — not a generic template you have to work around.
Every ERP we build is Fawtara-ready: it produces valid, structured invoices and connects directly to any OTA-accredited e-Invoicing Service Provider through secure API integration. We are not an Accredited Service Provider ourselves — we build the ERP layer that connects to one, so you're never locked into a single provider.
If you already run an ERP or accounting system, we can often integrate Fawtara compliance directly into it, instead of replacing what your team already knows.

Why Custom ERP Instead of Off-the-Shelf?
Off-the-shelf software forces your business to adapt to its rules. A custom ERP adapts to your business instead — your invoice numbering, your approval chain, your tax categories, your reporting.
For Fawtara compliance, that difference matters. A rigid, generic system can leave gaps that surface only when an invoice is rejected. A custom-built ERP is designed around your actual data and workflows from the start, so compliance fits naturally instead of being bolted on.
Answers, Straight.
Not always. If your current system can be integrated with an e-Invoicing Service Provider, we can add Fawtara compliance to it directly.
Secure Your Fawtara Readiness
Fawtara compliance is coming for every VAT-registered business in Oman. The businesses that prepare early avoid disruption — the ones that wait rebuild under pressure.
