Why choose a senior B2B web app development vendor
Most vendors talk about quality. We prove it with numbers.
IRPR has shipped over 200 products across 50+ countries. Our senior engineers average 10+ years of experience. We deliver every project with fixed pricing and a guaranteed 8-12 week timeline.
Our on-time delivery rate is 98%. We use a proven four-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and milestones.
Generic dev shop vs senior B2B web app development vendor
Not all vendors are equal. See how IRPR differs from the rest.
Generic dev shops often assign junior developers and charge by the hour. They lack experience with B2B compliance and scalability. Projects frequently run over budget and past deadlines.
IRPR assigns only senior engineers with 10+ years of experience. We use fixed pricing and a structured process to eliminate surprises. Every project includes compliance checks for SOC 2 and GDPR.
- Junior developers on your project
- Hourly billing with no cap
- No compliance expertise
- Unclear timeline
- No code ownership guarantee
- Scope creep without notice
- Senior engineers only (10+ years)
- Fixed price from $80K
- SOC 2 and GDPR compliance built in
- 8-12 week timeline
- Full code ownership
- Scope locked after Roadmap phase
Our process for building B2B web apps
Four phases from idea to release. No wasted cycles.
Every project starts with a Discovery call where we understand your goals and constraints. We then move to the Roadmap phase where we define scope, tech stack, and fixed price.
The Build phase is where our senior engineers code your app. We use React, Node.js, and PostgreSQL. The Release phase includes deployment, CI/CD setup, and documentation.
What ships with every B2B web app
You get more than just code. Every project includes these deliverables.
IRPR believes in full transparency. When we finish a project, you receive everything needed to run and maintain your app. No hidden fees or missing pieces.
