E-Invoicing among the SMEs is no longer a technological upgrade in the current dynamic business environment. E-invoicing in Saudi Arabia has become the center of regulatory changes due to the desire to transform towards digitization and financial transparency. In particular, e-invoicing will be implemented E-invoicing in Riyadh and other major cities to develop a safe and standardized method of reporting taxes. SMEs in KSA need to align with these updates as a way of being compliant with regulations, but more so to improve their operational credibility and financial accuracy in their day-to-day transactions.
The e-Invoicing for SMEs is also part of a wider Kingdom plan to enable small and medium-sized enterprises with the help of digital tools. Since its local economy is primarily based on SMEs, the latter are now forced to implement the ZATCA e-invoicing system to operate normally without interruptions. This guide describes who can qualify under the new mandate and how SMEs in Saudi Arabia can embrace the use of e-invoicing solutions with confidence. As 2025 brings new technical stages and deadlines, it is critical to be ahead in terms of compliance to any SME that is interested in sustainable expansion and effective tax management.
VAT compliance is a key issue of SMEs in Saudi Arabia, particularly the ones that are yet to adopt modern mode of invoicing. Such inefficiencies cause tax gaps and filing errors. e-Invoicing for SMEs is a good alternative because it digitizes records and helps to increase tax transparency.
The transition to e-Invoicing in Saudi Arabia assists companies to automate VAT reporting and makes it accurate. Through real-time data checks, SMEs in KSA will be able to reduce the risks of fraud and fulfill regulatory expectations. The use of e-Invoicing by SMEs has become a necessity in order to prevent the penalties of non-compliance and the need to be credible.
The Generation Phase of e-Invoicing for SMEs in Saudi Arabia has officially commenced in December 2021. In this stage, SMEs in KSA had to produce and send structured e-invoices through compatible electronic systems. Such invoices required some key details like QR codes and cryptographic stamps to be authentic and traceable. Although the real-time submission to the tax authority was still not mandatory, the businesses needed to abandon handwritten or unstructured digital invoices.
The Integration Phase, which began in January 2023, is the current and second stage of e-invoicing among SMEs. This Integration Phase step obliges SMEs in Saudi Arabia to integrate their invoicing systems to the FATOORA platform operated by ZATCA in real-time to validate the invoices and share the data. This step is compulsory in full compliance and every SME is given its own integration deadline based on its annual turnover unlike Phase 1.
This step is to be carried out in phases and is intended to harmonize VAT compliance in the country. In the case of SMEs in KSA, becoming part of the system has now become mandatory to ensure that there are no errors in tax reporting and auditing is done efficiently.
Regarding the Saudi Arabian e-Invoicing for SMEs, the small and medium-sized enterprises are usually defined as businesses that have annual revenues of less than SAR 15 million. Although not an official and standardized definition, this revenue level is commonly employed to recognize SMEs in Saudi Arabia since they lack the access to high technology systems and in-house IT support. This classification is important to identify the compliance time frame with ZATCA particularly when the implementation of e-invoicing in Saudi Arabia is phased to VAT-registered businesses.
ZATCA has rolled out several phases of the e-invoicing of Saudi Arabia, the second phase being the gradual increase in compliance to SMEs in the KSA depending on their annual revenue. where previous waves were directed to large businesses, the latest waves now only refer to SMEs in Saudi Arabia, with monthly deadlines between January and November 2025 being set to businesses with revenue between SAR 15 million and SAR 1.25 million.
Wave 11: an income of more than SAR 15 million – Period: 31 January 2025
Wave 12 Revenue > SAR 10 million– Deadline: 28 February 2025
Wave 13: revenue > SAR 7 million – Deadline: 31 March 2025
Wave 14: More than SAR 5 million revenue – Deadline: 30 April 2025
Wave 15: Revenue > SAR 4 million – Deadline: 31 May 2025
Wave 16: Revenue > SAR 3 million -Deadline: 30 June 2025
Wave 17: > SAR 2.5 million Revenue – Deadline: 31 July 2025
Wave 18: SAR 2 million October > Revenue Deadline: 31 August 2025

Wave 20: Income SAR > 1.5 million – End of program: 31 October 2025
Wave 21: Revenue greater than SAR 1.25 million Deadline: 30 November 2025
The recently announced wave 21 by ZATCA will focus on the smaller VAT-registered SMEs in Saudi Arabia that have annual revenues of more than SAR 1.25 million in any of 2022, 2023, or 2024. Such companies will now be obligated to connect their e-Invoicing of SMEs systems to the official Fatoorah platform. The Wave 21 compliance deadline is scheduled to be November 30, 2025, as a significant milestone in the digital tax transformation in Saudi Arabia.
Complying with the technical specifications put in place by ZATCA is one of the main challenges of e-Invoicing for SMEs. The KSA SMEs are required to produce XML/UBL-based invoices in QR codes and cryptographic stamps in order to achieve real-time compliance and verification.
Most of the SMEs in Saudi Arabia use legacy accounting systems which are not compatible with e-invoicing in Saudi Arabia. Such companies will have to restructure the current software or implement systems approved by ZATCA to fulfill the compliance requirements.
Implementation of e-Invoicing to SMEs is associated with high initial costs of software, training and consultation. These costs may become a financial burden to SMEs in KSA, particularly those that have a low access to technology funding.
The problem of data protection is a major concern in e-Invoicing among SMEs since the systems have to protect some sensitive financial data. To transmit invoices safely, SMEs in Saudi Arabia have to adhere to the encryption and storage standards of ZATCA.
The majority of SMEs in KSA lack the internal IT departments to manage the shift to e-invoicing in Saudi Arabia. Consequently, they tend to use third-party vendors to provide them with compliance support and technical integration.
Sustainable deployment of e-Invoicing for SMEs is one of the critical milestones in the current digitalization of Saudi Arabia. With the increased pressure of regulatory enforcement, SMEs in KSA need to shift towards automated invoicing solutions that are in line with the ZATCA guidelines and leave manual invoicing behind. Technical compliance to real-time validation of data, all elements of e-invoicing in Saudi Arabia are aimed at promoting financial transparency and better governance of taxes. In the case of the businesses located in such major hubs as Riyadh, early adoption of the e-invoicing requirement will create the smoother operation and minimize the risk of penalties and audit related issues.
Although the transition might be considered as a challenge, there are long-term advantages of e-Invoicing for SMEs such as enhanced accuracy, quicker processing, and enhanced compliance with the national tax laws. Since the compliance process with ZATCA goes in several waves, it is important that SMEs in Saudi Arabia keep themselves informed about the integration deadlines and implement appropriate invoicing options. Properly assisted and prepared, SMEs in KSA will be able not only to comply with the law but also to enhance their competitiveness in the changing Saudi business environment.
