Subject: Integration with FATOORA — Phase 2
We would like to inform you that your business is within the group targeted for integration with the FATOORA platform, and must integrate no later than the date set for your group.
Integration date: per your group
What is ZATCA's integration notice?
ZATCA applies e-invoicing Phase 2 to successive groups ("waves") of businesses, each chosen by its VAT-subject revenue in given years. ZATCA notifies the businesses concerned at least six months before their date, by the email and text messages registered with it, and the notice sets out the integration requirements and the business's date.
Phase 1: generation and storage
Since 4 December 2021: issuing invoices, credit and debit notes electronically and storing them, without connecting to ZATCA's systems.
Phase 2: integration
Since 1 January 2023, in successive waves: connecting the invoicing system to ZATCA's FATOORA platform, issuing invoices in a set format and sending them to ZATCA.
Not receiving a notice is not, by itself, proof that your business is out of scope. Check your business's account with ZATCA and the official announcements.
When must your business integrate with ZATCA?
Enter your VAT-subject revenue for each year you know, and we compare it with the officially announced waves. The figures are not sent anywhere or kept: the calculation runs in your browser only.

The wave cannot be determined precisely
No announced wave applies to you so far
From what you entered, your revenue has not passed the threshold of any wave ZATCA has announced so far. ZATCA may announce new waves; watch for its notices.
The date in ZATCA's notice is the reference for your business; confirm it in your business's ZATCA account.
This is a preliminary result, not an official determination of your tax obligations. The final reference is ZATCA's notice, your taxpayer account and the official laws and instructions.

Is there a fine for not integrating with ZATCA?
Breaching the e-invoicing requirements can lead to action and fines depending on the violation. The current classification starts with a warning and a period to correct it, then fines rise if the violation repeats within 12 months. Each violation has its own scale: not integrating is one; not issuing, not storing or changing invoices after issuance are others.
| Violation | First time | On repetition (SAR) | Time to correct |
|---|---|---|---|
| Not integrating all e-invoicing systems with ZATCA's systems from the set integration date, unless a technical fault at ZATCA is proven | Warning | 10,000 → 15,000 → 20,000 → 30,000 → 40,000 → 50,000 | 30 days |

Frequently asked questions
I received a message from ZATCA about integration. What should I do?
Read the notice and note the integration date it gives, then confirm it in your business's account with ZATCA. Make sure the invoicing system you use supports Phase 2 (integration), and register your invoicing units on the FATOORA portal before the date. Start early: registration needs a one-time code (OTP) from the portal and passing the compliance checks.
How do I know which wave my business belongs to?
ZATCA sets each wave by VAT-subject revenue in given years, and notifies the businesses concerned at least six months before their date by the email and text messages registered with it. The preliminary checker on this page gives an estimate; the final word is ZATCA's notice and your business's account with ZATCA.
I have not received a notice. Do I have to integrate?
Under ZATCA's Detailed Guidelines for E-Invoicing, a taxpayer is not required to implement Phase 2 until ZATCA notifies them. But not having a notice does not by itself mean your business is out of scope: the email or phone number registered with ZATCA may be out of date. Check your business's account with ZATCA and the official announcements.
What is the difference between Phase 1 and Phase 2?
Phase 1 (generation and storage) started on 4 December 2021 and requires issuing invoices and notes electronically and storing them. Phase 2 (integration) started on 1 January 2023 in successive waves and requires connecting the invoicing system to ZATCA's FATOORA platform and sending invoices to it in a set format.
Is integration with ZATCA mandatory for every business?
ZATCA applies Phase 2 gradually to waves it selects by revenue size; each wave is bound from its own date after being notified. The date therefore differs from one business to another. See the table of announced waves on this page and check your business's status with ZATCA.
What is the penalty for not integrating?
The simplified guideline classifying violations (2nd edition, May 2024) treats "not integrating all e-invoicing systems with ZATCA's systems from the set integration date" as a violation that starts with a warning and a period to correct it, with fines rising on repetition within 12 months. The details are in the violations table on this page, with the source.
Can I issue invoices before integration is complete?
Yes. Phase 1 (issuing invoices electronically and storing them) has applied to all taxpayers since 4 December 2021, and invoices must keep being issued electronically. From your business's integration date, invoices are also sent to ZATCA through the FATOORA platform.
Do I need to change my current invoicing software?
Not necessarily. What matters is that the solution you use meets the Phase 2 requirements and can be connected to the FATOORA platform. If your current software cannot integrate, move to one that can before your date.
How do I confirm my business's official date?
The reference is ZATCA's notice to the email and phone registered with it, your business's account on ZATCA's portal, and the wave announcements on ZATCA's official site (zatca.gov.sa). The link to each wave's announcement is in the waves table on this page.
Is WonderFatoora officially approved by ZATCA?
WonderFatoora is listed in ZATCA's e-invoicing Solution Providers Directory (Phase 2). ZATCA states that the directory is not an approval of the listed solutions, and that it considers a taxpayer compliant once the requirements are met, even if their provider is not listed. So we describe WonderFatoora as a solution that meets the e-invoicing requirements and is listed in ZATCA's directory, not as "approved".
