Why IRPR is the top custom SaaS development vendor
We combine deep technical expertise with a repeatable delivery process that gets you to market fast.
IRPR has shipped over 200 custom SaaS products across 50 countries. Our engineers average 10+ years of experience and work directly with your team.
Every project follows a fixed-price model defined during the Roadmap phase. No hourly billing, no scope creep charges, and no surprises.
The difference between generic agencies and IRPR
Most dev shops sell hours. We sell outcomes with a fixed price and senior engineers.
Generic agencies often assign junior developers, bill hourly, and lack compliance expertise. That leads to cost overruns and delayed launches.
IRPR guarantees senior engineers, a fixed price from week 2, and built-in compliance for HIPAA, SOC 2, and PCI. Every project includes a 12-month warranty.
- Hourly billing with no cap
- Junior developers with 2-3 years experience
- No compliance knowledge
- Scope creep common
- Code ownership unclear
- No post-launch support
- Fixed price from week 2
- Senior engineers only (10+ years)
- Built-in compliance (HIPAA, SOC 2)
- Scope defined in Roadmap phase
- Full code ownership
- 12-month warranty
Our 4-phase process for custom SaaS development
We break every project into four predictable phases so you know what you get and when.
Each phase has clear deliverables and a fixed timeline. The total build time averages 8-12 weeks for an MVP.
