OVERVIEW
SAP is the most common ERP among large businesses in Oman, from SAP ECC to SAP S/4HANA and SAP Business One for mid-sized companies. Whatever your version, Fawtara needs the same outcome: every in-scope invoice must leave SAP as a PINT OM e-invoice, travel through an accredited service provider and come back with a status.
Webtel connects SAP using standard interfaces, such as IDocs, OData and web services, or SAP Integration Suite if you already use it. The right option depends on your release, hosting and existing middleware. Your billing process stays the same; e-invoicing runs alongside it.
Most SAP e-invoicing work is about data. Tax codes, customer VAT numbers, units of measure and billing types must all map cleanly to PINT OM. We review real billing documents early, so gaps are found and fixed during the project, not during go-live week.
We also plan how your team works with e-invoices in SAP: who monitors rejections, how corrections are made and how statuses are shown, so the process runs smoothly from the first day of your Fawtara phase.
CAPABILITIES
Billing documents, credit memos and debit memos are converted to PINT OM.
Buyer VAT numbers, addresses and tax codes are checked before sending.
Delivery and rejection statuses are shown against the SAP document.
No modification of SAP standard code.
COMMON CHALLENGES
These are the issues we see most often. Each one is planned for from the start, so it does not surface in the week before go-live.
01
Existing tax codes may need a clear mapping to Fawtara tax categories.
02
Invoices, credit memos, down payments and intercompany billing behave differently.
03
The project must fit SAP transport and testing cycles.
04
Some groups need a solution that works now and after a move to S/4HANA.
THE FAWTARA MODEL
Fawtara, the Oman Tax Authority's e-invoicing programme, uses a Peppol-based five-corner model. Invoices are issued in the PINT OM format and travel through an accredited service provider, which delivers them to the buyer and passes the tax data to the OTA. Invoices cannot be sent from an ERP directly to the OTA.
Step 1
In your ERP, accounting or billing system.
Step 2
Checked against PINT OM and Omani VAT rules.
Step 3
Your accredited service provider exchanges it over Peppol.
Step 4
Delivered to the buyer's own service provider and system.
Step 5
Tax data reaches the Oman Tax Authority through Fawtara.
HOW IT WORKS
We document the systems, data and approvals involved in your invoicing.
Fields, rules and exceptions are defined against PINT OM and Omani VAT rules.
The connection is built and tested with real invoices, including the edge cases.
After go-live, statuses and exceptions are monitored so nothing is missed.
WORKED EXAMPLE
How an SAP customer invoice becomes a delivered Fawtara e-invoice.
See It in a Demo →WHY IT MATTERS
Every in-scope invoice is issued in the PINT OM format from your go-live date.
Data is checked before it leaves your system, not after a buyer or the OTA flags it.
E-invoices are stored electronically, ready for audits and OTA requests.
Standard interfaces keep your system's upgrade path clean.
Delivery and rejection statuses are visible in your own system.
The same approach works if you move from ECC to S/4HANA.
IN DETAIL
BEFORE YOU GO LIVE
Having these ready before the assessment shortens the project and keeps your Fawtara go-live on schedule. Our free Fawtara readiness checklist is a good place to start.

WHY WEBTEL
FAQS
Not necessarily. Some businesses use SAP's own compliance product and others use an external integration. We assess your release and licences and recommend the route that fits.
Yes. Both can be connected to the same Fawtara flow, which is common during a migration.
No. E-invoices are processed after billing, so your billing run completes as it does today.
Fawtara uses PINT OM, the Omani specification of the Peppol International invoice model, exchanged as structured XML through an accredited service provider.
No. Under the five-corner model, e-invoices travel through an accredited service provider, which delivers them to the buyer and passes the tax data to the OTA.
It depends on your system, the number of invoice types and the quality of your data. We give you a dated plan after the assessment, working back from your Fawtara phase.
