Which format does Saudi Arabia use for e-invoicing?

ZATCA e-invoice (XML, UBL-based) with cryptographic stamp. Documents go to ZATCA, through the Fatoora platform.

Does Oltrano control the invoice number in Saudi Arabia?

Yes. Numbering is gap-free and sequential, resets on your schedule and never reuses a number.

Is Saudi Arabia a clearance country?

Yes. The document is authorised by ZATCA, through the Fatoora platform before it is legally valid.

What is the Peppol EAS code for Saudi Arabia?

Saudi Arabia has no code in the official Peppol EAS list, so we do not guess one.

The facts

What issuing in Saudi Arabia actually involves

Format	ZATCA e-invoice (XML, UBL-based) with cryptographic stamp
Goes to	ZATCA, through the Fatoora platform
Regime	Clearance — the authority authorises the document before it is valid
Invoice number	Stays ours: gap-free, sequential, yours to control
Seller tax ID	VAT registration number
Buyer tax ID	VAT registration number
Peppol EAS code	Not in the official EAS list
Integration	Direct, no third-party provider needed

The part that costs a day

The catch nobody writes down

Phase 2 is not a file format change, it is a device: each issuing solution is onboarded with its own cryptographic identity, and every B2B invoice is cleared before it can be given to the buyer, while simplified B2C invoices are only reported afterwards. The two flows behave differently, and treating a B2B invoice as simplified is the mistake that gets noticed at audit.

Your numbering stays yours

We issue gap-free, sequential numbers that reset on your schedule and are never reused — including for voided documents, which keep theirs. The authority takes the document as numbered.

Tax is computed from the base

Never extracted from the gross. The two formulas differ by a cent and the wrong one gets the file rejected. The leftover cent is declared as payment rounding (BT-114), where the standard puts it.

Straight talk

What we do not do in Saudi Arabia.

We do not hold your signing certificate, we do not file your periodic returns, and we are not your accountant.

Issuing here goes through a certified provider, with your own credentials. We build the document, validate it, send it and record what comes back.
