e-Invoicing for SMEs in Saudi Arabia, Eligibility & Implementation Guide

Small and Medium Enterprises (SMEs) and Micro, Small, and New Enterprises (MSNEs) are the backbone of Saudi Arabia's economy, contributing significantly to employment and economic growth. According to recent statistics, SMEs make up nearly 99% of all businesses in Saudi Arabia and employ around 60% of the private sector workforce. Their contribution to the Kingdom’s GDP is crucial, particularly in non-oil sectors like retail, manufacturing, services, and healthcare.

The implementation of e-invoicing in Saudi Arabia for SMEs is the most important part of the e-invoicing timeline. This blog will provide a detailed guide to ZATCA e-invoicing updates in 2025 for SME’s.

VAT Tax Gaps and the Need for E-Invoicing

VAT compliance is one of the most critical issues faced by SMEs in Saudi Arabia. Many small businesses still rely on traditional, manual invoicing systems, which are prone to errors and inefficiencies. This has resulted in discrepancies in VAT filings and difficulty in ensuring transparency. Saudi Arabia's Zakat, Tax, and Customs Authority (ZATCA) mandated the shift to e-invoicing to bridge these gaps and align with global tax compliance standards.

E-invoicing automates VAT reporting and ensures compliance with real-time data validation, significantly reducing the risk of errors, fraud, and non-compliance. This transition is crucial for SMEs to stay competitive and avoid penalties.

Phased Implementation of E-Invoicing for SMEs

The implementation of e-invoicing in Saudi Arabia for SMEs has been structured in two major phases:

Phase 1 (Generation Phase)

This phase required businesses to begin generating e-invoices, effective December 2021. Businesses were expected to issue digital invoices with QR codes and cryptographic stamps, but there was no mandatory integration with ZATCA’s system.

Phase 2 (Integration Phase)

This phase started in January 2023 and is now a critical focus for businesses. It mandates businesses to integrate their e-invoicing systems with ZATCA’s FATOORA platform. This integration ensures real-time clearance and validation of invoices. Phase 2 is implemented in waves  and the deadlines for integration vary based on the business's annual revenue generally announced at least 6 months before the implementation timeline.

Who are Considered SMEs in Saudi Arabia for E-Invoicing?

There is no specific, standardized guideline for defining SMEs in Saudi Arabia. However, businesses with annual revenues under SAR 15 million are generally considered small and medium-sized enterprises for the purpose of e-invoicing. This is because businesses in this revenue range are less likely to have in-house tech teams or customized ERPs. This classification is important for determining the compliance deadlines and phases of ZATCA’s e-invoicing mandates.

Key Deadlines for SMEs: ZATCA Compliance Timeline

Here are the announcements for SMEs based on the above criteria regarding the Phase 2 e-invoicing implementation timeline in KSA. Ten phases have already been announced and implemented, but these apply to larger businesses and are excluded from the SME classification. Below is the complete ZATCA Phase 2 Waves implementation timeline.

Recent Announcement of Wave 21

Wave 21, the latest update from ZATCA, affects smaller VAT-registered businesses, including those with annual revenues exceeding SAR 1.25 million in 2022, 2023, or 2024. These businesses must integrate their e-invoicing solution with the Fatoorah platform by November 30, 2025.

Challenges SMEs Face with E-Invoicing Implementation

The implementation of e-invoicing for SMEs differs significantly from that of large corporations due to several key factors: Here are some major challenges

1. Understanding Technical Requirements: E-invoices must comply with ZATCA’s stringent technical standards, including QR codes, cryptographic stamps, and XML/UBL format. These features are crucial for validating invoices in real time.
2. Integration with Existing Systems: Many SMEs use outdated systems that are not compatible with ZATCA’s platform. They must invest in new software or upgrade existing systems to ensure compliance.
3. Compliance Costs: Implementing e-invoicing may involve high upfront costs for SMEs, particularly those with limited resources. The investment in new software and staff training can be burdensome for smaller businesses.
4. Data Security: Protecting sensitive financial data is paramount. SMEs need to ensure that their invoicing systems are secure and compliant with ZATCA’s data protection requirements.
5. Lack of Technical Expertise: Many SMEs lack in-house IT teams capable of managing the integration and ongoing compliance with ZATCA’s platform, requiring external assistance.
