Why IRPR is the best business web app development agency
We ship faster, charge fixed prices, and own the outcome.
IRPR has shipped over 200 web apps for clients in 50+ countries. Our engineers average 10+ years of experience. We do not use junior developers or offshore teams. Every project is staffed with senior engineers who write production code from day one.
We use a four-phase process: Idea (week 1), Roadmap (week 2), Product (weeks 3-10), Release (weeks 11-12). The Roadmap phase produces a fixed price quote and a detailed scope. No surprises.
How we differ from other agencies
Most agencies bill hourly and change scope. We do not.
Generic agencies often start with a discovery phase that costs $5K-$15K and delivers a vague estimate. They bill by the hour, so every change request adds cost. Code quality varies because they staff junior engineers.
IRPR gives you a fixed price after a two-week Roadmap. The Roadmap costs a flat fee and produces a complete scope, wireframes, and timeline. If the scope changes, the price changes only by mutual agreement.
- Hourly billing with no cap
- Junior developers on your project
- Scope creep without notice
- No compliance expertise
- Code you cannot extend
- No post-launch support
- Fixed price after Roadmap phase
- Senior engineers only (10+ years avg)
- Scope defined in writing week 2
- HIPAA, PCI-DSS, SOC 2 built in
- Full source code ownership
- 12 weeks of post-launch support included
Our process for building your business web app
Four phases. No fluff. You see progress every week.
The Idea phase is a 3-day workshop where we map your business requirements, user flows, and technical constraints. We identify the core feature set that delivers the most value first.
Then we build. The Product phase is eight weeks of sprint-based development. You get a staging environment after week 4. The Release phase includes load testing, security audit, and deployment to production.
What ships with your business web app
You get more than code. You get a production-ready system.
Every project includes infrastructure, monitoring, and documentation. You do not need to hire a DevOps engineer after we finish. The app runs on AWS or GCP with auto-scaling and 99.9% uptime SLA.
We also include a 30-day post-launch support period. During that time we fix bugs, handle user feedback, and make small adjustments. After that, we offer ongoing maintenance at a flat monthly rate.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Staging and production environments on AWS
- Database with automated backups
- Sentry error tracking and monitoring
- User authentication via Auth0 or Clerk
- API documentation (OpenAPI/Swagger)
- Admin dashboard for managing users and data
- Responsive design for mobile and desktop
- 30-day post-launch support included
