Peppol Accredited Service Provider · E-Invoicing Software in Oman
Simplify E-Invoicing in Oman with Bytize
Bytize is a Peppol Accredited Service Provider in Oman. Send invoices from SAP, Microsoft Dynamics or Salesforce, and Bytize prepares them for exchange on Oman’s Peppol network under Fawtara.
Decision 189/2026: businesses with annual supplies above OMR 5 million must e-invoice from 1 April 2027, and all other VAT-registered businesses from 1 October 2027.
What is E-Invoicing in Oman?
E-Invoicing in Oman runs through Fawtara, the Oman Tax Authority's (OTA) e-invoicing programme. VAT-registered businesses must issue tax invoices in an approved electronic format and send them through an accredited service provider on the Peppol network, with tax data reaching the OTA.
Once your start date arrives, paper invoices, PDFs and emailed images no longer count as tax invoices. Your ERP can't send invoices straight to the OTA: they must pass through an accredited service provider.
What an e-invoice in Oman must follow
- Format: Structured XML following PINT OM, Oman's version of the Peppol International invoice model
- Exchange: Through your accredited service provider to the buyer's provider on Peppol (5-corner model)
- Reporting: Tax data reaches the OTA as the fifth corner of the exchange
- Records: E-invoices must be archived electronically for 10 years (15 years for real estate)
Who must comply
- Applies to VAT-registered businesses in Oman; scope follows VAT registration, not physical presence
- Supplies to businesses and to consumers are covered from your start date, including simplified tax invoices
- Foreign suppliers without an Omani VAT registration are outside Fawtara; the Omani buyer self-accounts under reverse charge
- Government entities are not yet scheduled; onboarding is proposed for 2028

How E-Invoicing in Oman works with Bytize
Oman uses the Peppol 5-corner model: your invoice goes through your accredited service provider to the buyer's provider, and tax data goes to the OTA.
Send invoice data
Your ERP sends invoice data to Bytize as JSON through the API.
Validate and convert
Bytize converts the data to PINT OM XML and checks it against the official rules.
Deliver on Peppol
The invoice is sent to the buyer’s provider on Peppol through Bytize’s accredited service provider partner.
Report to the OTA
Tax data goes to Fawtara as the fifth corner through Bytize’s accredited partner, and the status comes back to you.
Buyer receives
The buyer's provider validates the invoice and delivers it to the buyer's system.
Status back to you
Every status is pushed to your ERP by webhook, so your team sees what was delivered or rejected.
Fawtara e-invoicing solutions in Oman, built for your business
Bytize’s e-Gate API turns your ERP data into the PINT OM format the OTA requires, ready for exchange on Peppol.
Send JSON, get PINT OM
Post invoice data as JSON. Bytize maps it to PINT OM automatically, and the same payload works across every Peppol country we cover.
Validation before sending
Every invoice is checked against the Peppol rules before it’s sent, and failures are held for review, never silently dropped.
Certified Peppol delivery
Invoices are delivered through a certified Peppol Access Point partner, so you never manage certificates yourself.
Real-time status webhooks
Every state change, from draft to validated to sent, plus any validation failure, is pushed to your system.
Receive supplier invoices
Incoming Peppol invoices from your suppliers in Oman arrive parsed into the same JSON shape, ready for your accounting system.
Tamper-evident archive
Each transmission joins a SHA-256 hash chain, and delivery receipts are kept in immutable storage for audits.
Readable PDF copy
Every sent invoice comes with a PDF version for buyers who want a visual copy. The structured XML stays the legal invoice.
Benefits of E-Invoicing in Oman
E-invoicing is a legal requirement, but done well it also speeds up payments and removes manual work from your finance team. Here's what changes when you switch with Bytize.
Stay compliant without extra work
Every invoice is issued in PINT OM and exchanged on Peppol, so you meet Fawtara's format rules from your start date.
Get paid faster
Invoices reach your buyer's system in seconds instead of days by email or post, so approval and payment start sooner.
Fewer errors and rejections
Each invoice is validated against the official rules before it's sent, so missing fields and wrong tax codes are fixed before your buyer sees them.
No more manual data entry
Supplier invoices arrive as structured data your ERP can post directly, freeing your team from retyping and checking PDFs.
Audit-ready records
Every invoice and status message is stored in a tamper-evident archive you can retrieve and export when the tax authority asks.
One setup for every market
One API for every Peppol market Bytize supports, so expanding to a new market doesn’t mean a new provider.
