OTA Fawtara e-invoicing
Catch invoice errors before the Oman Tax Authority does. InfiTax checks each invoice against OTA business rules for VAT compliance, builds PEPPOL PINT-OM XML and sends it to the OTA through our ASP partner FawtaraX.
Reports of Decision No. 189/2026 give 1 April 2027 for businesses with annual supplies above OMR 5 million and 1 October 2027 for all others. See the Oman e-invoicing mandate timeline and its sources.

Fawtara integration
E-invoicing ERP integration is how invoice data from your ERP reaches the Oman Tax Authority as a valid e-invoice under Fawtara. InfiTax handles it in two ways.
InfiTax is built into the Infinity platform, so invoices raised in the Infinity ERP modules flow into e-invoicing without a separate system. Each invoice is checked against OTA business rules, built as PEPPOL PINT-OM XML and sent through FawtaraX. The software supports Arabic and English.
InfiTax integrates with SAP, Oracle, Microsoft Dynamics, Odoo and Tally, as well as the Infinity ERP, so you can keep the ERP you already run. The OTA says ERP systems can be retained, depending on your arrangement with your accredited service provider, and your data still has to map to the Oman PINT specifications. The E-Invoicing Hub console, shown below, lists a Connect any ERP panel for this.

Before you choose
The questions buyers ask us first, answered with what we can stand behind today.
Pricing is quoted per case, after we understand your needs: your invoice volume, your ERP and how many companies you run. The OTA says it charges taxpayers no fees for e-invoicing and does not set what providers charge.
We plan the rollout with you, around your ERP, your data and your OTA date, instead of promising a fixed number of weeks. The OTA expects taxpayers to have integrated with their provider on or before their go-live date, so it pays to start early.
The Infinity ERP is cloud-hosted, and InfiTax is built into it. If you run another ERP, you keep it: InfiTax works with the systems listed under Fawtara integration with your ERP.
Yes. The InfiTax software is bilingual, and the OTA's FAQ says invoices can be issued in different languages, provided they follow the Oman VAT legislation.
Our free readiness checklist asks ten questions and suggests your next steps. It runs in your browser and sends nothing.

FAQ
InfiTax is Infinity's e-invoicing solution for Oman. It is built into the transactional core of our platform, not added on. Each invoice gets a direct, validated route to the Oman Tax Authority's Fawtara platform through AI-driven pre-validation, PEPPOL PINT-OM XML payloads and secure transmission via our exclusive ASP partner, FawtaraX.
Fawtara is the Oman Tax Authority's e-invoicing system. Invoices are issued as structured XML, validated and exchanged through accredited service providers, and tax data is reported to the OTA. Read the Oman e-invoicing guide for who is affected, the dates and the formats.
Yes, for VAT-registered businesses. Reports of Decision No. 189/2026 give 1 April 2027 for businesses with annual supplies above OMR 5 million and 1 October 2027 for all others. The OTA also offers a checker that estimates your period from your VATIN. Confirm your date with the OTA.
Yes. InfiTax is built for OTA Fawtara compliance. Its XML payload generator strictly enforces the PEPPOL PINT UBL 2.1 (PINT-OM) schema on every document, and structured tag mapping ensures each payload mirrors the exact specification the Oman Tax Authority's systems expect. The result is verified schema conformity and complete statutory audit trails.
No. The Oman Tax Authority says a PDF invoice is not an e-invoice and that XML is the mandatory structured format. InfiTax generates PEPPOL PINT-OM XML payloads, checked before they are sent.
A built-in AI engine inspects every transaction data point in real time, before the payload is generated. Line items, tax codes, buyer identifiers and currency fields are checked against OTA business rules automatically. Anomalies, missing fields and formatting errors are flagged and corrected instantly, so every invoice is certified clean before it leaves the system.
Yes, unless your own company is accredited. The OTA requires every e-invoice to be validated by the issuer's accredited service provider. With InfiTax, invoices reach the Oman Tax Authority through FawtaraX, an OTA-accredited ASP. See how to choose an e-invoicing provider in Oman.
FawtaraX is on the Oman Tax Authority's list of accredited service providers (ASPs). Infinity holds an exclusive ASP partnership with FawtaraX.

Yes. The OTA says a taxpayer can disconnect from one accredited service provider and connect to another through the Fawtara Portal. Only one provider can be connected at a time.
