Generic Agency vs. Expert Sales Website Development Vendor
Most agencies treat your project like a commodity. IRPR treats it like a product.
We have seen clients waste months with generic dev shops that bill hourly and fail to deliver. They get an unfinished site with no CI/CD and no ownership.
IRPR is different. You get a fixed price, a clear roadmap, and production-ready code in 12 weeks. Every project includes compliance, testing, and deployment.
- Slow start - 4 weeks just to agree on scope
- Hourly billing with no cap
- No PCI-DSS compliance
- No CI/CD pipeline
- Code stays on their servers
- No post-launch support contract
- Fixed price quoted in week 2
- Senior engineers only (no junior padding)
- PCI-DSS compliant by default
- CI/CD on GitHub Actions from day one
- Full code ownership transferred on launch
- 30-day post-launch support included
