Why hire an expert B2B web app development firm
Data shows why IRPR is the right partner for your next project.
IRPR has shipped 200+ products across 50+ countries. Our B2B web apps serve manufacturing, logistics, and fintech clients. Each project is built by senior engineers with 8+ years of experience. We do not outsource to junior developers.
Our fixed pricing model eliminates budget surprises. The average B2B web app costs between $80,000 and $250,000 and ships in 8-12 weeks. We deliver a fully functional MVP with real users, not just a prototype.
Generic dev shop vs an expert B2B web app development firm
The difference is experience and process.
Most dev shops charge by the hour and deliver late. They use junior developers and generic templates. You end up with code you cannot maintain and no clear timeline.
IRPR works differently. Every project starts with a Roadmap phase (week 2) where we define the exact scope and price. You get a fixed quote, a dedicated senior team, and a working product in 8-12 weeks.
- Hourly billing with uncertain total cost
- Junior developers learning on your project
- No fixed timeline or milestone guarantees
- Generic templates that need customization
- No compliance experience (HIPAA, PCI-DSS)
- Code ownership unclear
- Fixed price quoted in week 2
- Senior engineers only (8+ years average)
- 8-12 week delivery with milestone tracking
- Custom architecture from scratch
- 80+ compliance projects completed
- Full source code ownership from day one
How IRPR builds your B2B web app in 4 phases
Our process from idea to release.
Phase 1: Idea Validation. We review your spec, competitive landscape, and technical requirements. This takes 1 week and ends with a product brief. You get a clear document describing what will be built and why.
Phase 2: Roadmap. We design the architecture, create user stories, and estimate the exact price. This is week 2. You get a fixed quote and a detailed project plan. No surprises.
What you get when you ship a B2B web app with IRPR
Every project includes these deliverables by default.
We do not hand off code and walk away. You get a complete production system with documentation, monitoring, and a deployment pipeline. Your team can take over or we can continue supporting.

- Staging and production environments on AWS
- Database schema and migration scripts
- Postman collection for API endpoints
- Admin dashboard with user management
- Error tracking with Sentry
- Performance monitoring with Datadog
