Why hire a custom web app development agency
A custom web app built by IRPR replaces spreadsheets, manual processes, and off-the-shelf software that doesn't fit your workflow.
Off-the-shelf software forces you to adapt your business to its limits. A custom web app built by IRPR adapts to your exact workflow, data model, and compliance needs. We have shipped over 200 custom web apps across 50 countries, each one tailored to a specific business process.
Our typical client comes to us after trying three different SaaS tools and still having to export data to spreadsheets. We replace that patchwork with a single web app that connects to your existing tools via API. The result is a system that your team actually uses.
How IRPR differs from other web development agencies
Most agencies bill hourly and scope creep is the norm. IRPR fixes that with fixed pricing and a structured process.
We have seen clients waste months with agencies that start building without a clear roadmap. They end up with a bloated app that misses core requirements and goes over budget. IRPR's process prevents that by defining the entire scope in week 2 before any code is written.
The Roadmap phase (week 2) produces a detailed technical specification with wireframes, data models, and a fixed price. You approve the roadmap, and we build exactly that. No surprises, no hourly billing, no scope creep.
- Hourly billing with no cap
- Scope creep is your problem
- Junior developers on your project
- No roadmap before building
- Code quality is inconsistent
- You own nothing until final payment
- Fixed price from week 2
- Scope is locked in the Roadmap
- Senior engineers only (8+ years)
- Roadmap phase before any build
- Code reviews and automated testing
- Full code ownership from day one
Our process for custom web app development
We move from idea to production in four phases. Each phase has clear deliverables and a fixed timeline.
The process starts with a 1-week Idea phase where we align on goals, user personas, and core features. No code yet. Just whiteboarding and documentation.
Then the Roadmap phase (week 2) produces a technical specification, wireframes, and a fixed price. You approve it, and we move to Product (weeks 3-10) where we build the MVP in 2-week sprints. The Release phase (weeks 11-12) covers deployment, testing, and documentation.
What ships with every custom web app
Every project includes a production-ready codebase, CI/CD pipeline, and monitoring. No loose ends.
When we finish a project, you get more than just code. You get a fully deployed application with infrastructure, monitoring, and documentation. Your team can take over immediately or we can continue with a maintenance retainer.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or CircleCI
- Deployed to AWS or Vercel with auto-scaling
- PostgreSQL database with migrations
- Sentry error tracking and logging
- Unit and integration tests (coverage report)
- API documentation (Swagger or Postman)
- Admin dashboard for managing users and data
- Stripe or payment gateway integration
- User authentication with OAuth (Google, GitHub)

Why teams hire us.
Fixed price, not hourly
Every custom web app project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
Every developer at IRPR has 8+ years of experience. No juniors, no interns, no offshore teams. Your project is built by people who have shipped production web apps for a decade.
Full code ownership
You own the entire codebase from day one. Source code is in your GitHub repo. No licensing fees, no platform lock-in, no restrictions. You can take the code anywhere.
8-12 week MVP timeline
We ship a working MVP in 8 to 12 weeks. That includes design, development, testing, and deployment. Most agencies take 6 months for the same scope.
Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliant web apps. Compliance is not an afterthought. We architect for it from the first sprint.
Post-launch support included
Every project includes 30 days of post-launch support for bug fixes and minor adjustments. We don't disappear after deployment. Your app stays stable.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
