Why Generic Agencies Fall Short For B2B Web Apps
Most web development shops lack the depth needed for complex B2B requirements.
Generic agencies often ship code that does not scale or pass compliance audits. They rely on junior developers and charge hourly, leading to budget overruns.
IRPR is different. We assign only senior engineers who have built production systems at scale. Our fixed-price contracts remove financial risk.
- Junior and offshore teams
- Hourly billing with no cap
- No compliance knowledge (SOC 2, HIPAA)
- You own nothing until final payment
- 6-9 month delivery for a basic MVP
- Ongoing vendor lock-in
- Only senior engineers from the start
- Fixed price from the Roadmap phase (week 2)
- Built-in SOC 2, PCI-DSS, HIPAA compliance
- Full code ownership from day one
- 8-12 week MVP delivery
- No lock-in – we hand over all code and CI/CD
Our Process: From Idea to B2B Web App in 12 Weeks
We use a four-phase framework to turn your concept into production software.
Every engagement follows our Idea-Roadmap-Product-Release model. This gives you clarity, fixed pricing, and a working product fast.
We start with a discovery call, then build a detailed Roadmap. After you approve the plan, we build the MVP in 8-12 weeks and deploy it to your infrastructure.
What Ships With Every B2B Web App Engagement
Every project includes a standard set of deliverables that make your app production-ready.
We do not cut corners. Delivery includes not just code but the entire operational foundation for running a web application.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and automated tests
- Dockerized deployment ready for AWS, GCP, or Azure
- Sentry error tracking and Datadog monitoring
- Stripe or Chargebee integration for billing
- API documentation (OpenAPI/Swagger)
- User authentication with Auth0 or Cognito
- Load testing report with k6 or JMeter
- Design system in Figma for future iteration
- Post-launch support for 30 days
