The subscription math always favors ownership.
At SAR 300/month, Rewaa costs you SAR 3,600 per year. After 5 years: SAR 18,000 — and you still don't own the software. Cancel, and your data access depends on their export tools. With StartPOS, you pay once and the license is yours permanently.

The single most important difference.
A ZATCA Phase 2 invoice rejection is not just an inconvenience. For B2B transactions, a rejected invoice means the buyer cannot deduct input VAT, which can delay payment and damage supplier relationships that took years to build.
Gulf Union Ozone built StartPOS from the ground up to meet ZATCA's exact UBL 2.1 XML technical specifications — cryptographic signing, QR code generation, CCSID device registration, and Fatoorah portal submission. We have maintained a 0% rejection rate across every client deployment.
Rewaa added ZATCA compliance to a pre-existing inventory management platform. Their system works — but ZATCA Phase 2 was designed as a compliance layer on top of an architecture built for a different purpose. Our architecture was built ZATCA-first.
Every Saudi client we have deployed for ZATCA Phase 2 integration has achieved a 0% invoice rejection rate. That record stands across all deployments since we launched.
Honest guidance.
Choose StartPOS if…
- You want to own your software and eliminate ongoing subscription costs
- ZATCA compliance is non-negotiable — you need 0% rejections, not "usually works"
- You want AI analytics that answer questions in Arabic by voice
- You need a local office in Jeddah, Riyadh, Umluj, or Jazan
- You plan to use WhatsApp to send invoices to customers
- You're in retail, wholesale, electronics, or auto repair
- You want to stay live on ZATCA for 3–5+ years without subscription escalation
Rewaa may suit you if…
- You prefer a monthly subscription to spread cost over time
- Your primary need is inventory management with ZATCA as a secondary requirement
- You are already locked into the Rewaa ecosystem and switching cost is prohibitive
- You primarily operate from Riyadh and don't need multi-region local support
