Why choose IRPR for Shopify Plus development?
Our track record speaks for itself.
We have shipped over 200 products across 50 countries. 98% of our projects finish on time. Our average delivery timeline is 12 weeks from kickoff to launch.
Every project is handled by senior engineers with 10+ years of experience. We use automated testing, CI/CD pipelines, and monitoring to ensure 99.9% uptime.
The difference between generic agencies and IRPR
Most agencies bill hourly and miss deadlines. We don't.
Generic dev shops often use junior developers and change scope mid-project. They charge hourly and have no accountability for timelines.
IRPR assigns senior engineers, locks scope in week 2, and delivers on time. We include 12 months of post-launch support at no extra cost.
- Hourly billing
- Unclear scope
- Junior developers

- No post-launch support
- Fixed price from day one
