Why hire an expert B2B web app development team
Building a B2B web app in-house takes 6-12 months and costs 2x more than hiring an expert team.
IRPR has shipped over 200 B2B web apps across 50 countries. Our team of senior engineers averages 12 years of experience per developer. We use a four-phase framework: Idea, Roadmap, Product, Release. The Roadmap phase takes one week and produces a fixed-price quote with a full technical specification.
We handle compliance out of the box. For healthcare clients, we build HIPAA-compliant apps with BAA agreements. For fintech, we follow PCI-DSS level 1 standards. For SaaS, we implement SOC 2 controls from day one. Every app ships with a CI/CD pipeline, automated tests, and monitoring via Datadog or Sentry.
Generic dev shop vs expert B2B web app team
Not all development teams deliver the same quality. Here is what sets IRPR apart.
Many generic dev shops assign junior developers to your project and charge by the hour. They have no process for compliance, no fixed timeline, and no senior oversight. You end up with a half-finished app and a budget that has doubled.
IRPR assigns a team of senior engineers only. We have a fixed price from week 2. We follow a documented four-phase framework. Every project includes compliance reviews, automated testing, and a post-launch support period. You own the code and the infrastructure.
- Junior developers with 2-3 years experience
- Hourly billing with no cap
- No compliance expertise (HIPAA, PCI, SOC 2)
- No fixed timeline or roadmap
- Code may not be transferable
- No post-launch support
- Senior engineers only (12+ years average)
- Fixed price quote after 1-week Roadmap
- Built-in HIPAA, PCI-DSS, SOC 2 controls
- 8-12 week MVP timeline with milestones
- Full code ownership and infrastructure transfer
- 2 weeks of post-launch support included
How we build your B2B web app
Our four-phase framework turns your idea into a production-ready app in 8-12 weeks.
Phase 1: Idea. We spend 2-3 days understanding your business, users, and technical requirements. You get a project brief with scope, risks, and a rough estimate.
Phase 2: Roadmap. One week of deep technical design. We produce a detailed specification, a fixed price quote, and a timeline with milestones. You approve before we write any code.
