Why choose IRPR for custom application development
We deliver production-ready software faster and with fewer surprises.
IRPR has shipped over 200 custom applications for clients in 50 countries. Our fixed-price model means no hourly billing and no cost overruns. You know the budget from week 2.
Our senior engineers average 10+ years of experience. We use modern stacks like Next.js, Node.js, PostgreSQL, and AWS. Every project includes CI/CD, automated testing, and security audits.
How we compare to other custom app development agencies
Most agencies hide costs and assign junior developers. IRPR does the opposite.
Generic dev shops often charge hourly, change requirements mid-project, and hand off unfinished code. They use offshore teams with timezone delays and no documentation.
IRPR gives you a fixed price after a 2-week Roadmap phase. You get a dedicated team of senior engineers, weekly demos, and full ownership of the source code. No surprises.
- Hourly billing with no cap
- Junior developers on your project
- Scope creep without price adjustment
- No documentation or handover plan
- Timezone delays with offshore teams
- You don't own the code
- Fixed price from week 2
- Senior engineers only (10+ years avg)
- Scope locked after Roadmap phase
- Full documentation and architecture diagrams
- Async-first, 4-hour overlap with Americas/Europe
- You own 100% of the source code
Our process for building custom applications
We break every project into four phases: Idea, Roadmap, Product, Release.
Phase 1: Idea - We validate your concept and define core features. This takes 1-2 days with a quick discovery call.
Phase 2: Roadmap - We create a detailed spec, wireframes, and a fixed-price quote. This takes 2 weeks and costs $2,500 (credited toward build).
