e-Invoicing in Saudi Arabia: A Step-by-Step Guide for Your Business

The Zakat, Tax, and Customs Authority (ZATCA), formerly the General Authority of Zakat and Tax (GAZT), initiated e-invoicing in Saudi Arabia with a draft amendment published on September 17, 2020, in line with the Value Added Tax Implementing Regulations.

Phase 2 began on January 1, 2023, and is being rolled out in stages based on business turnover. Under this phase, businesses must fully integrate their systems with ZATCA’s platform and meet all requirements.

Recently, ZATCA announced Wave 24 for Phase 2, which mandates that VAT-registered businesses with turnover exceeding SAR 375,000 must integrate their e-invoicing solution with the Fatoora Portal by 30th June 2026.

Key Takeaways: 

• Applies to all resident VAT-registered taxpayers; non-resident taxpayers are exempt from issuing e-invoices.
• Two invoice types: Standard (B2B/B2G; clearance, input-VAT claimable) and Simplified (B2C; report to ZATCA within 24 hours in Phase 2).
• Issue Standard invoice for sales ≥ SAR 1,000, intra-GCC/exports, nominal sales; Simplified allowed < SAR 1,000 unless buyer needs input-VAT credit.
• Mandatory Arabic, machine-readable XML with embedded PDF/A-3, UUID, digital signature, cryptographic stamp, sequential numbers; direct system integration with ZATCA (Fatoora) via APIs.
• Phase 2 is staggered by turnover waves from 2023 to 2026; Wave 23 requires businesses with SAR 750k–1m turnover to integrate by 31 Mar 2026.

What is e-Invoicing in Saudi Arabia?

e-Invoicing, also known as FATOORA in Saudi Arabia, refers to the process of issuing and handling invoices in a digital format. This system replaces traditional paper invoices with electronic versions, including Credit & Debit Notes (CDNs)., exchanged between buyers and sellers through an online integrated solution.

An electronic invoice is a tax invoice created in a structured digital format using electronic means. Unlike a scanned or converted paper invoice, a true electronic invoice is generated directly through an electronic system.

Here are the key differences between traditional invoicing and digital e-invoicing:

1. Structured Format: E-invoices are created in a machine-readable format, such as XML along with human readable version  in pdf/ A-3 format.
2. Integration with ZATCA: E-invoices are generated through ZATCA’s online integrated system (FATOORAH System) or e-invoicing software, which validates and stores the invoice details.
3. Reporting: E-invoices are reported to ZATCA’s FATOORAH system in the specified time.
4. Direct Transmission: E-invoices are sent directly to the buyer’s enterprise system through an integrated network, provided it is connected to ZATCA's system.

Additional Fields: E-invoices include mandatory fields such as IRN (Invoice Reference Number) and QR Code, in addition to the standard details in a KSA VAT invoice.

Scope of e-Invoicing in Saudi Arabia

e-Invoicing in Saudi Arabia applies to all taxable persons who conduct economic activities independently for generating income and are either registered for VAT in the Kingdom or required to register under the VAT Law and its implementing regulations. The scope includes:

Types of e-invoices in Saudi Arabia

ZATCA clarified that e-invoices should be issued for all types of tax invoices under VAT. There are different types of e-invoices, and below are the frequently used tax invoices:

Standard tax invoice

It is the invoice issued by a Business to another Business (B2B) or business to a government (B2G), containing all the elements of a tax invoice, especially the VAT registration number of the buyer and seller.

Key Attributes of Standard Tax Invoice

• Allows consumers to claim input VAT deductions.
• Contains detailed information about the seller, buyer, transaction, and products/services.
• Must be cryptographically stamped and cleared by ZATCA.
• Integrated with the ZATCA portal and must be sent for verification in real time

Below is the sample format of a standard e-invoice:

Simplified tax invoice

It is often issued by a Business to consumer (B2C) containing the main prescribed elements of a simplified tax invoice. 

Key attributes of Simplified tax invoice

• No VAT deduction capability for the buyer.
• In Phase 1: Simply share with customers.
• In Phase 2: Must be reported to ZATCA within 24 hours of issuance.

Below is the sample  format of a simplified tax invoice:

Further, ZATCA explained in the guidelines that the e-invoice to be issued varies based on the type of supply. Here’s the table explaining the type of e-invoice to be issued:

*When selling taxable or zero-rated supplies to a taxable or non-taxable legal person of less than SAR 1000, the seller might issue simplified tax invoices. However, if the buyer wants to claim input VAT, they can request the seller to issue a standard tax invoice.

^Non-taxable legal person means a business in Saudi Arabia but not registered under VAT due to the registration threshold.

Phases of e-invoicing in Saudi Arabia

The ZATCA is implementing e-invoicing in two phases:

Phase 1: Generation

Implemented on December 4, 2021, the Generation phase is the initial step towards e-invoicing. This phase requires taxpayers to:

1. Generate invoices electronically.
2. Include specific details.

Taxpayers must generate e-invoices, credit notes, and debit notes through a ZATCA-compliant e-invoicing solution. This applies to all taxpayers (excluding non-resident taxpayers) and any other parties issuing tax invoices on behalf of VAT-registered suppliers.

The process for issuing e-invoices will be similar to current invoice practices but through a compatible electronic billing system, which could be an online cash register or e-invoicing software (either on-premises or cloud-based).

The Generation phase does not require any integrations or communications to send or receive e-invoices through the ZATCA e-invoice system (FATOORAH)..

Phase 2: Integration

Since January 1, 2023, Phase 2 has been implemented in waves for specific taxpayer groups based on turnover. This phase involves integrating e-invoicing solutions with ZATCA’s e-invoicing systems (FATOORAH) and sending e-invoices for validation before issuance.

This phase includes technical and procedural requirements for generating, submitting, validating, and sharing e-invoices:

• Connect to FATOORAH using Application Programming Interfaces (APIs)
• Generate a Universally Unique Identifier (UUID)
• Create and add a digital signature
• Produce a sequential number for each e-invoice
• Include a cryptographic stamp
• Sellers must 'clear' the Tax Invoice from ZATCA in real-time and then share it with buyers as a legally valid e-invoice (simplified invoices must be sent to ZATCA within 24 hours from generation).

Phase 2 is being rolled out in waves for targeted taxpayer groups. It began on January 1, 2023, for businesses with a turnover exceeding SAR 3 billion. 

ZATCA has announced 16 waves to date. Here are the waves notified by ZATCA till now

Who implements e-invoicing in Saudi Arabia?

The Zakat, Tax and Customs Authority (ZATCA) is the authority for e-invoicing in Saudi Arabia. GAZT, now known as ZATCA, issued the draft e-Invoicing Regulations in KSA in March 2021. The authority allowed the public and stakeholders to provide feedback on the e-Invoicing Regulations on or before 17th April 2021. The e-invoicing Regulations were finally published on 28th May 2021.

What is the process flow of e-invoicing in Saudi Arabia?

The process flow for generating an e-invoice in Saudi Arabia differs based on the type of invoice. With the phase 2 implementation date approaching, it is important to understand the process of generating electronic invoices.

Let’s go through them one by one.

e-Invoicing Penalties for Non-Compliance

Penalties for non-compliance of e-invoicing rules in KSA vary based on the nature and frequency of the offence. Initial violations are usually met with warnings, while repeated offenses result in harsher penalties. 

• Non-issuance or non-archiving of e-invoices: SAR 5,000 to SAR 50,000
• Incorrect amendments or cancellations of e-invoices: SAR 10,000 to SAR 50,000
• Missing QR code on simplified invoices: Warning 
• Failure to report system issues affecting e-invoicing: Warning
• Absence of buyer VAT registration number on e-invoices (B2B): Warning 

During initial inspections, ZATCA issues warnings rather than penalties, allowing three months for compliance. Persistent non-compliance after this period results in a SAR 1,000 fine, which increases if required changes are not made within the given timeframe.

Repeated Violations

• SAR 1,000 for the second violation
• SAR 5,000 for the third
• SAR 10,000 for the fourth
• SAR 40,000 for the fifth

Violations discovered after 12 months are treated as new offences, starting with a warning.
