POS Billing Software Integration with ZATCA: Accqrate
Updated On : Jan 13th, 2025 | 23 min read

Introduction: The Changing Landscape of POS Systems in Saudi Arabia
Point of Sales (POS) systems are critical to improving customer satisfaction and ensuring seamless business operations. However, with the launch of E-invoicing Phase 2 by ZATCA (Zakat, Tax, and Customs Authority), businesses in Saudi Arabia face new challenges in integrating legacy POS systems with ZATCA’s compliance requirements.
Our research reveals that 30-40% of businesses continue to use outdated, standalone POS machines that cannot communicate with external systems like ZATCA. Migrating to a modern POS system isn’t always feasible, especially for businesses heavily reliant on their existing setup.
The Challenge: Integrating Legacy POS Systems with ZATCA
Many POS machines currently in use are built on obsolete technology and lack the capability to integrate with external systems like ZATCA. Below are the key challenges businesses face when trying to achieve compliance:
Key Obstacles in POS-ZATCA Integration
- Obsolete Technology: Legacy POS applications are outdated and lack the scalability to integrate with modern APIs.
- Offline Functionality: Most POS systems operate offline, meaning they store data locally and perform reconciliation at the end of the day.
- Customer Experience: Any changes to POS systems must not increase customer waiting time, as this can impact overall satisfaction.
- Inbuilt Print Formats: Many POS devices have fixed invoice formats that are not customizable to include QR codes or ZATCA-compliant details.
The Solution: Accqrate POS ZATCA Integrator
To address these challenges, Accqrate developed a range of POS integrators that provide seamless ZATCA compliance for both offline and
online POS systems.
With a proven track record of integrating widely used POS systems in Saudi Arabia — including SAGE, AX, Denali, and more — Accqrate has successfully helped businesses from retail, pharma, and education sectors achieve E-invoicing compliance.
Here’s how Accqrate’s integrators solve the problem:
1. Offline POS Billing Software Integrator

This solution is ideal for offline POS systems that operate without a constant internet connection. Many retail shops use standalone POS devices that store data locally and reconcile with the server at the end of the business day.
Here’s how the Accqrate Offline POS ZATCA Integrator works:
- A lightweight .exe file is installed on the POS device.
- The POS system communicates with the .exe through a local host call to generate a ZATCA-compliant QR code in real-time.
- The QR code is printed on the customer invoice.
- At the end of the day, the integrator pushes the approved XML files to ZATCA servers for compliance.
Alternative Solution:
If your POS system cannot modify the PDF invoice to include a QR code, Accqrate offers an alternative:
- Accqrate generates the compliant invoice on your behalf.
- The compliant invoice can be sent to the customer via email or WhatsApp automatically.
Online POS Billing Software Integrator

This solution is best suited for online POS systems that communicate in real-time with their servers. In this case, Accqrate provides cloud-based APIs that interact directly with ZATCA’s servers to ensure instant compliance.
Here’s how the Accqrate Online POS Integrator works:
- The POS system generates the customer invoice.
- Accqrate’s cloud API connects with ZATCA and gets the invoice approval in milliseconds.
- The cashier can immediately issue a fully compliant invoice to the customer.
- If your POS system cannot update the PDF print format, Accqrate can generate and print the compliant invoice using the same template you currently use.
