Why Choose a Professional B2B Web App Development Vendor
A professional vendor delivers on time, on budget, and with compliance built in.
IRPR has shipped 200+ B2B web apps across 50 countries. Our average MVP timeline is 12 weeks. We use fixed pricing so you know the cost before we write a line of code.

How IRPR Differs from Other Vendors
Most agencies bill hourly and miss deadlines. IRPR does not.
Generic dev shops often use junior developers and change scope mid-project. They bill hourly and deliver late. You end up with buggy code and no ownership.
IRPR assigns senior engineers only. We give you a fixed price in week 2. We ship in 8-12 weeks. You own the code and the CI/CD pipeline from day one.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- Scope creep without change orders
- No compliance expertise
- Deliverables 3-6 months late
- No source code ownership
- Senior engineers with 10+ years experience
- Fixed price from week 2
- Scope locked in Roadmap phase
- HIPAA, PCI-DSS, SOC 2 built in
- 8-12 week MVP delivery
- Full source code ownership
Our Process for Building B2B Web Apps
We follow a four-phase process that guarantees clarity and speed.
Phase 1 is the Idea phase where we define the product vision and user stories. Phase 2 is the Roadmap phase where we create a detailed plan and fixed price.
Phase 3 is the Product phase where we build the MVP in 8-12 weeks. Phase 4 is the Release phase where we deploy to production and hand over the code.
