With the adoption of complete electronic invoicing (e-invoicing) in Saudi Arabia, the business landscape is spearheaded by the Zakat, Tax and Customs Authority (ZATCA), represents a monumental shift toward a fully digitized economy.

While Phase 1 (The Generation Phase) successfully introduced mandatory e-invoicing for all VAT-registered businesses, Phase 2 the Integration Phase offers a much more complex and strategic undertaking by moving beyond the simple generation of e-invoices to connect your systems directly with ZATCA's platform.

Designed to boost transparency, efficiency, and trust across every transaction, this phase is a catalyst for significant internal digital transformation.

Understanding the essential requirements is now crucial in order to avoid penalties, maintain business continuity, and harness the long-term benefits of enhanced financial data accuracy.

Let us take a look at how businesses can make sure these documents are validated in real time by ZATCA’s Fatoora platform.

Understanding the Integration Phase

Segmenting taxpayers into groups on the bases of criteria such as revenue size, starting with the largest entities, Phase 2 is the wave-based rollout. The major difference in phase 2 is that each wave is announced with a minimum six-month preparation window before the enforcement date.

Once your business model is notified, crucially, integration is mandatory and it is risky to delay preparation until the announcement. These technical requirements necessitate time for testing, system upgrades, and potential vendor negotiations, which is what smart businesses are starting for their internal audits and are planning now.

So, what exactly does ZATCA’s Integration Phase involve? 

Well, in short, it’s about linking your invoice system directly with ZATCA’s e-invoicing platform. Every invoice is transmitted (in XML format) to the authority, and is validated, and ensured that they are stored securely for future reference.

Key requirements businesses must meet include:

• Implementing secure APIs to connect with ZATCA’s Fatoora system 
• Automating invoice validation and digital signing 
• Generating mandatory QR codes for every invoice, supporting quick compliance checks 
• Storing invoices securely for up to five or six years 
• Ensuring every invoice has a unique digital signature and cryptographic stamp

Who Needs to Comply and By When?

Introduced in waves, from January 1, 2025, this integration phase requires companies with annual VATable income over 7 million SAR in 2022 or 2023 to get compliant. Other companies, those that include small and medium enterprises, will have their own deadlines before the end of 2025, as notified by ZATCA.

If your company falls into any of the upcoming waves, the preparation of the same is essential because ZATCA gives at least six months’ notice, but early action is what helps to avoid penalties and a smooth transition.

Challenging Aspects for Businesses

Integrating with ZATCA’s systems isn’t as simple for businesses face several technical and process challenges: 

• Upgrading or adapting ERP and accounting software for integration 
• Ensuring every invoice meets data formatting and content standards 
• Training staff to manage new workflows and compliance obligations 
• Managing the costs (and time) associated with new system implementation

It’s easy to feel overwhelmed—especially if you’re trying to juggle ongoing business activities with compliance demands.
