Saudi-Arabia

This article was updated on 7 July 2026 to reflect the latest implementation of Phase 2 (Integration phase) of Saudi Arabia's e-invoicing framework, including the continued rollout of ZATCA's wave-based integration programme and the most recent guidance on compliance requirements for businesses required to connect their invoicing systems to the FATOORA platform.

Introduction & digital tax strategy

Saudi Arabia has established one of the world's most advanced electronic invoicing frameworks as part of its broader Vision 2030 digital transformation agenda. Introduced by the Zakat, Tax and Customs Authority (ZATCA), the e-invoicing mandate is designed to strengthen tax compliance, curb the shadow economy, and modernise how businesses issue, exchange and report invoices.

Since the introduction of the Generation phase in December 2021, Saudi Arabia has progressively expanded the regime through a wave-based Integration phase, requiring businesses to connect their invoicing solutions directly to the government's FATOORA platform. Unlike many jurisdictions, Saudi Arabia combines real-time invoice clearance for standard tax invoices with near-real-time reporting for simplified tax invoices within a single, unified framework.

This article explores how Saudi Arabia's e-invoicing system works in detail, including the legal framework, implementation timeline, scope of the mandate, the roles of ZATCA and the FATOORA platform, technical requirements for standard and simplified tax invoices, compliance obligations, and practical steps businesses can take to prepare for current and future implementation phases.

Understanding Saudi Arabia's e-invoicing framework

Saudi Arabia has become one of the leading Middle Eastern countries in digital tax transformation. As part of its ambitious Vision 2030 strategy, the Kingdom is modernising public services, increasing economic transparency and accelerating the digitalisation of business processes. Electronic invoicing forms a key pillar of this transformation by helping businesses replace paper-based invoicing with secure, structured digital invoices while enabling more efficient tax administration.

To support these objectives, the Zakat, Tax and Customs Authority (ZATCA) introduced mandatory e-invoicing through its national FATOORA programme. The initiative seeks to improve VAT compliance, combat tax evasion and fraud, enhance the quality of transaction data, and reduce administrative burdens for both businesses and the tax authority. It also aligns Saudi Arabia with the growing global trend towards Continuous Transaction Controls (CTCs), where tax authorities receive invoice data electronically as part of the invoicing process rather than solely through periodic VAT returns.

Saudi Arabia's implementation differs from many European e-invoicing models. Rather than introducing a single mandatory exchange network, ZATCA has implemented a phased approach consisting of two distinct stages:

• Phase 1 (Generation phase): Since 4 December 2021, in-scope businesses have been required to generate, issue and store electronic tax invoices using compliant electronic invoicing solutions.

• Phase 2 (Integration phase): Beginning on 1 January 2023, businesses are being required to integrate their invoicing systems directly with ZATCA's FATOORA platform. The rollout is taking place in waves based on taxpayers' annual VAT-taxable revenue, with affected businesses receiving at least six months' notice before their mandatory integration date.

Today, Saudi Arabia's e-invoicing framework continues to expand as additional waves of taxpayers enter Phase 2. Businesses operating in the Kingdom should therefore monitor ZATCA announcements carefully to determine when integration becomes mandatory and ensure their invoicing systems comply with the latest legal and technical specifications.

Historical and global context

Saudi Arabia's e-invoicing mandate reflects a broader global shift towards Continuous Transaction Controls (CTCs), where tax authorities receive transaction data electronically during the invoicing process rather than relying solely on periodic VAT returns. While early real-time clearance models originated primarily in Latin America, jurisdictions across Europe and the Middle East have adapted CTC concepts to fit their specific regulatory environments. The Zakat, Tax and Customs Authority (ZATCA) designed the FATOORA programme to bridge these methodologies, combining real-time clearance for standard B2B tax invoices with 24-hour reporting for simplified B2C tax invoices within a single national framework.

Within the Gulf Cooperation Council (GCC), the Kingdom's phased rollout under the Vision 2030 digital transformation agenda has set a regional benchmark, providing a structural template for neighbouring countries such as Oman. Unlike European frameworks that frequently rely on decentralised exchange networks or Peppol-based models, such as Germany's EN 16931 rules or France's Y-model, Saudi Arabia mandates direct API integration between taxpayer invoicing solutions and ZATCA's central platform. This centralised architecture grants the tax administration immediate transaction visibility, helping to reduce the shadow economy, combat tax evasion, and modernise commercial operations across the Kingdom.

The phased timeline in Saudi Arabia

Saudi Arabia has adopted a phased approach to implementing mandatory e-invoicing, allowing businesses to progressively prepare for increasingly advanced compliance requirements. The rollout consists of two main phases: the Generation phase (Phase 1), which focuses on issuing and storing compliant electronic tax invoices, and the Integration phase (Phase 2), which connects taxpayers’ invoicing systems to ZATCA’s FATOORA platform.

Since January 2023, ZATCA has been introducing Phase 2 through successive implementation waves based on taxpayers' annual VAT-taxable revenue. Depending on the implementation wave, eligibility is determined using taxable revenue from one or more previous tax years, with affected businesses receiving at least six months' notice before their mandatory integration date.

By avoiding a single mandatory deadline, the Kingdom facilitates a smoother transition. This wave-based approach allows ZATCA to onboard taxpayers of all sizes systematically, granting them the necessary lead time to upgrade invoicing systems and ensure seamless technical integration.

As Phase 2 continues to expand, businesses should regularly monitor communications from ZATCA to determine whether they have been included in a future rollout wave. Even if a business has not yet received a notification, it is advisable to begin assessing its current invoicing processes and technical capabilities to ensure it can comply when required.

Legal framework

Saudi Arabia's e-invoicing framework is governed by legislation issued by the Zakat, Tax and Customs Authority (ZATCA), supported by implementing resolutions and detailed technical specifications that define the obligations businesses must meet when issuing, transmitting, and storing electronic invoices.

The country's e-invoicing programme, known as FATOORA, forms part of Saudi Arabia's broader digital transformation strategy and supports the Kingdom's objective of improving tax compliance, reducing the shadow economy and increasing transparency through the digitalisation of commercial transactions.

As the framework continues to evolve, ZATCA periodically publishes updates to its technical specifications, implementation standards, and integration requirements, so businesses should always rely on the latest official documentation when assessing their compliance obligations or implementing technical changes.

Official legislation

• Electronic Invoicing Regulation (الئحة الفوترة اإللكترونية), the foundational regulation published by ZATCA on 4 December 2020, establishing the legal obligation for VAT-registered taxpayers to issue electronic invoices and the framework for the phased implementation of e-invoicing in Saudi Arabia.

• Electronic Invoicing (FATOORA) Controls, Requirements, Technical Specifications and Procedural Rules (ضوابط ومتطلبات ومواصفات فنية وقواعد إجرائية اللازمة لتنفيذ أحكام لائحة الفوترة الإلكترونية), also known as the E-Invoicing Implementation Resolution, most recently updated on 19 May 2023, which provide the detailed technical and procedural requirements businesses and solution providers must follow to ensure compliance.

Whenever possible, businesses should consult the official ZATCA publications and technical documentation rather than relying solely on secondary sources, as the Authority regularly issues updates to technical specifications and implementation guidance.

Administrative oversight

Saudi Arabia's e-invoicing framework is primarily administered and enforced by the Zakat, Tax and Customs Authority (ZATCA), which is responsible for the development, implementation, and oversight of the mandate.

ZATCA issues the e-invoicing regulation, publishes technical specifications and implementation guidance, manages the phased rollout of the FATOORA programme, and monitors compliance with the applicable e-invoicing requirements.

Where relevant, Saudi Arabia’s broader digital transformation agenda and fiscal policy objectives provide the policy context for the mandate, but ZATCA remains the main authority for day-to-day e-invoicing compliance.

Zakat, Tax and Customs Authority (ZATCA)

ZATCA is the government authority responsible for administering Saudi Arabia's e-invoicing framework.

Its responsibilities include:

• Developing and maintaining the Kingdom's e-invoicing regulations.

• Publishing technical specifications, implementation guides and compliance requirements.

• Managing the phased rollout of the FATOORA programme.

• Operating the national e-invoicing platform used during the Integration phase.

• Monitoring compliance and enforcing the mandatory e-invoicing requirements.

Businesses should refer to ZATCA's official publications for the latest regulatory updates, technical specifications and implementation timelines.

Ministry of Finance

The Ministry of Finance oversees Saudi Arabia's broader fiscal and financial policy and supports the Kingdom's digital transformation agenda under Vision 2030, the country’s long-term national strategy to diversify the economy, modernise public services, and reduce reliance on oil.

Although ZATCA is responsible for the day-to-day administration of the e-invoicing mandate, the Ministry plays an important role in shaping the national policy objectives that underpin the digitalisation of tax administration and financial reporting.

FATOORA

FATOORA is Saudi Arabia's national electronic invoicing system operated by ZATCA.

Rather than being a regulatory authority itself, FATOORA is the government platform through which businesses subject to Phase 2 (the Integration phase) connect their compliant invoicing solutions with ZATCA.

Depending on the type of invoice issued, FATOORA is used to:

• Validate and clear standard tax invoices before they are shared with customers.

• Receive reporting data for simplified tax invoices after they have been issued.

• Verify that invoice data complies with ZATCA's technical requirements.

The platform forms the technical backbone of Saudi Arabia's e-invoicing ecosystem and enables ZATCA to receive invoice data electronically as part of its Continuous Transaction Controls (CTC) model.

Scope of the mandate

Saudi Arabia's e-invoicing mandate applies to VAT-registered persons established in the Kingdom, as well as any party required to issue tax invoices on behalf of a VAT-registered supplier. The requirements cover both the Generation phase (Phase 1) and the Integration phase (Phase 2), although additional technical obligations apply to businesses that have been notified by ZATCA to integrate with the FATOORA platform.

The scope of the mandate is broad and is intended to ensure that invoice data is created, exchanged, and, where required, reported electronically in accordance with ZATCA's technical specifications.

Who must comply?

The e-invoicing requirements apply to:

• VAT-registered businesses established in Saudi Arabia.

• Resident taxable persons required to issue tax invoices under the Saudi VAT legislation.

• Third parties issuing invoices on behalf of VAT-registered businesses, where permitted by law.

Beyond generating electronic invoices in compliance with the Generation phase requirements, businesses selected for Phase 2 (Integration phase) must also connect their compliant invoicing solutions to ZATCA's FATOORA platform once they receive official notification from the Authority.

Which transactions are covered?

Saudi Arabia's e-invoicing framework applies to most domestic taxable transactions requiring the issuance of a tax invoice, including:

• Business-to-Business (B2B) transactions.

• Business-to-Government (B2G) transactions.

• Business-to-Consumer (B2C) transactions through the use of simplified tax invoices.

Depending on the type of transaction, businesses may be required to issue either a standard tax invoice or a simplified tax invoice, each of which follows a different compliance process. These differences are explained later in this guide.

Are any businesses excluded?

The e-invoicing requirements generally do not apply to:

• Businesses that are not registered for VAT in Saudi Arabia.

• Transactions that fall outside the scope of the e-invoicing rules or are otherwise specifically excluded under the VAT and e-invoicing regulations, such as supplies that do not require the issuance of a tax invoice.

Businesses should assess their VAT obligations carefully to determine whether they fall within the scope of the mandate.

Phase 2: Additional requirements

Being within the scope of Saudi Arabia's e-invoicing mandate does not necessarily mean a business must immediately integrate with ZATCA.

The Integration phase is being introduced gradually through implementation waves based on a business’s annual VAT-taxable revenue. Businesses become subject to the Phase 2 technical requirements only after receiving an official notification from ZATCA specifying their mandatory integration date.

Organisations that have not yet entered Phase 2 must nevertheless continue complying with the Generation phase requirements and should begin preparing their systems for future integration.

Saudi Arabia's e-invoicing requirements

Phase 1: Generation phase

Phase 1 is enforceable for all taxpayers in scope, excluding non-resident taxpayers, and for any other parties issuing tax invoices on behalf of suppliers subject to VAT.

Businesses subject to Phase 1 must ensure that their invoicing solution:

• Generates invoices electronically.

• Produces invoices containing all mandatory VAT information.

• Prevents invoices from being altered after issuance.

• Complies with the security and integrity requirements defined by ZATCA.

• Stores invoices electronically in accordance with ZATCA's requirements.

E-invoicing-compliant systems must not allow prohibited functions defined by ZATCA, including undetected alteration or deletion of issued invoices.

Certain other practices are no longer permitted under the Generation phase, including the use of handwritten invoices or invoice generation using basic word-processing or spreadsheet software that does not meet ZATCA’s technical requirements.

Businesses must retain invoices and related records in accordance with Saudi record-keeping requirements. Under Article 66 of the VAT Implementing Regulations, records must be kept in the Kingdom, physically or electronically, and cloud-based arrangements must provide compliant access in the Kingdom.

Phase 2: Integration phase

Phase 2 applies to businesses that have been notified by ZATCA to integrate with the FATOORA platform.

Businesses subject to Phase 2 must, in addition to complying with Phase 1 requirements, ensure that their invoicing solution can:

• Integrate with the FATOORA platform using ZATCA's published APIs and technical specifications.

• Meet all technical validation requirements.

• Generate invoices using the prescribed structured data format.

• Apply the required security and integrity controls before invoices are transmitted.

Failure to complete the required integration by the applicable deadline may result in non-compliance with the Saudi e-invoicing regulations.

Standard tax invoices vs. simplified tax invoices

Saudi Arabia distinguishes between two types of electronic invoices:

• Standard tax invoices are generally used for B2B and B2G transactions. They contain the seller and buyer details and the buyer’s VAT number where the buyer is registered for VAT. These invoices follow a clearance model, meaning they must be validated by ZATCA through the FATOORA platform before being issued to the customer.

• Simplified tax invoices are typically used for B2C transactions. These invoices are issued directly to the customer and subsequently reported to ZATCA within the required timeframe.

This distinction is one of the key features of Saudi Arabia's e-invoicing framework.

Invoice requirements

Electronic invoices must include the mandatory information required under Saudi VAT legislation and comply with ZATCA's technical specifications. Depending on the invoice type, additional elements, such as QR codes, UUIDs, and cryptographic stamps, may also be required.

QR code requirements

For simplified tax invoices, a QR code must be generated by the taxpayer at issuance and included on the invoice. For cleared standard tax invoices, the invoice returned by ZATCA contains the clearance data and related QR elements, which must be presented where the invoice is shared with the buyer in human-readable form. The QR code requirement is one of the key technical features of the Saudi e-invoicing framework and helps enable verification of invoice authenticity.

Invoice identifiers and technical fields

Depending on the invoice type and ZATCA's technical specifications, electronic invoices may also need to include a UUID, an invoice counter value, a previous invoice hash, and other prescribed structured data fields. For standard tax invoices, additional buyer and transaction data may also be required under the VAT legislation and the relevant technical rules.

Businesses must use compliant electronic formats in accordance with ZATCA's technical specifications. During the Integration Phase, invoices may be generated in XML or PDF/A-3 with embedded XML; however, only the XML version is submitted to FATOORA for clearance, and the cleared invoice may then be shared with the buyer in structured XML or human-readable PDF/A-3 with embedded XML, where permitted.

The human-readable version of the invoice must be in Arabic, and another language may be included alongside it. Arabic or Hindi numerals may be used, and either is treated as Arabic for invoice presentation purposes. Where applicable, the human-readable version must also include the QR code and any other mandatory data elements described above.

Businesses must also maintain secure electronic records and retain invoices in accordance with Saudi record-keeping requirements.

As ZATCA periodically updates its technical specifications, organisations should ensure their ERP or e-invoicing solution remains compliant with the latest requirements.

Technical architecture

Saudi Arabia's e-invoicing framework is based on a Continuous Transaction Controls (CTC) model, where invoice data is exchanged electronically between businesses and the Zakat, Tax and Customs Authority (ZATCA) through the national FATOORA platform.

Unlike traditional invoicing models, where businesses simply generate invoices and retain them for audit purposes, Saudi Arabia's framework requires certain invoice data to be transmitted to ZATCA as part of the invoicing process, enabling the Authority to validate or receive invoice information electronically and helping improve VAT compliance and reduce fraud.

Penalties for non-compliance

Businesses subject to Saudi Arabia’s mandatory e-invoicing requirements must comply with ZATCA’s rules. Failure to meet these obligations may result in warnings, corrective measures, and administrative penalties imposed by ZATCA.

The specific penalty depends on the nature and severity of the non-compliance and whether it is a first or repeat offence. ZATCA has the authority to investigate potential violations and apply corrective measures in accordance with the applicable legislation and regulations.

Examples of non-compliance may include:

• Failing to issue electronic tax invoices where required.

• Using an invoicing solution that does not comply with ZATCA's technical requirements.

• Failing to integrate with the FATOORA platform once the business becomes subject to Phase 2 (Integration phase).

• Omitting mandatory invoice information.

• Altering invoice data after an invoice has been issued.

• Failing to retain electronic invoices and related records in accordance with the applicable record-keeping requirements.

Depending on the circumstances, ZATCA may impose financial penalties and may require businesses to take corrective action to address identified compliance issues.

As Saudi Arabia's e-invoicing framework continues to evolve, businesses should regularly review ZATCA's latest guidance to ensure they remain compliant with both the legal and technical requirements.

How businesses can prepare

As Saudi Arabia continues to roll out Phase 2 (the Integration phase), businesses should begin preparing for compliance even before they receive a notification from ZATCA. Early preparation can help minimise disruption and ensure a smoother transition once integration becomes mandatory.

To prepare, businesses should:

• Review their invoicing processes to ensure they comply with Saudi Arabia's e-invoicing requirements.

• Monitor ZATCA announcements to determine when they will be included in a Phase 2 implementation wave.

• Assess their ERP or e-invoicing solution to confirm it supports FATOORA integration and meets the latest technical specifications.

• Test integration readiness, including invoice generation, clearance or reporting flows, and the handling of required invoice data fields.

• Train internal teams, including finance, tax and IT, on the new invoicing, technical, and compliance requirements.

• Keep track of ZATCA guidance and any changes to technical or legal requirements.

Taking these steps early will help businesses reduce implementation risks and maintain compliance as Saudi Arabia's e-invoicing framework continues to evolve.

Conclusion 

Saudi Arabia has built a highly developed e-invoicing framework through the FATOORA programme and the phased implementation of the Generation and Integration phases. The Kingdom is modernising invoice processing, strengthening VAT compliance and improving transparency across the business landscape.

For businesses operating in Saudi Arabia, e-invoicing is no longer simply a regulatory formality, it is becoming an integral part of day-to-day financial operations. As ZATCA continues to expand the Integration phase through successive implementation waves, organisations should ensure they understand their compliance obligations, monitor ZATCA announcements regarding future implementation waves and assess whether their invoicing systems meet the latest technical requirements.

Preparing early is essential. By reviewing internal processes, implementing a compliant e-invoicing solution and staying informed of regulatory developments, businesses can minimise disruption and ensure they remain compliant as Saudi Arabia's digital transformation continues.

Whether your business is already in scope for the Integration phase or preparing for a future rollout wave, a proactive approach today will help ensure a smoother transition and support long-term compliance with Saudi Arabia's e-invoicing requirements.
