Introduction
In today’s digital economy, financial transparency and efficiency are no longer optional. The Saudi Arabian Zakat, Tax and Customs Authority (ZATCA) is guiding that transformation through its e-invoicing regime (also known as “FATOORAH”), requiring businesses to issue, process and retain invoices in a structured electronic format.
Rather than being just a compliance burden, e-invoicing represents a powerful shift toward smarter operations, stronger auditability and deeper business trust.
What is ZATCA E-Invoicing?
According to ZATCA, electronic invoicing is the procedure that aims to convert the issuance of paper invoices (and credit/debit notes) into an electronic process that allows invoice exchange and processing in a structured electronic format between buyer and seller via an integrated electronic solution.
An “electronic invoice”, per ZATCA, is a tax invoice generated in a structured electronic format through electronic means—importantly, a paper invoice merely scanned or converted is not considered an electronic invoice.

ZATCA divides its e-invoicing rollout into two major phases:
Phase 1 – Generation Phase:
Enforced from 4 December 2021 for taxpayers subject to the E-Invoicing Regulation. This phase requires generating invoices via a compliant electronic solution and storing them, rather than using handwritten spreadsheets or manual/ unstructured systems.
Phase 2 – Integration Phase:
Enforceable from 1 January 2023, and implemented in waves. In this phase the e-invoicing solution must integrate with ZATCA's systems (FATOORAH), with invoices issued in required formats and additional fields.
Why E-Invoicing Matters?
Here are several reasons, clearly aligned with ZATCA’s objectives:
Regulatory compliance
Non-compliance may lead to issues because ZATCA mandates the structured format and integration.
Operational efficiency
Generating invoices electronically via compliant solution, and ultimately integrating with authority systems, reduces manual effort, errors and duplication.
Financial accuracy & audit-readiness
Structured data, mandatory fields and storage ensure that audit trails are complete, improving transparency. ZATCA
Digital-era readiness
For businesses operating in or with Saudi Arabia, adapting to these standards positions them better for future expansion, integration with digital supply chains and advanced tax regimes.

| Aspect | Phase 1 (Generation) | Phase 2 (Integration) |
|---|---|---|
| Requirement | Generate and store electronic invoices via a compliant electronic solution. | Integrate the invoicing solution with ZATCA's platform (FATOORAH) and issue invoices in prescribed format. |
| Focus | Digitalisation of invoice issuance and storage. | Automation of transmission, real-time connectivity and structured format. |
| Timeline | Enforceable from 4 Dec 2021. ZATCA+1 | Enforceable from 1 Jan 2023 (waves). ZATCA+1 |
| Technical burden | Moderate - switch to structured solution, including required fields. | Higher - system-to-authority integration, specified formats, additional fields. |
| Business Impact | Mainly internal change of invoicing process and storage. | Broader change: workflows, system integrations, possibly POS/ERP adjustments. |
