Why an experienced B2B web app development team matters
Building custom web apps requires senior engineers who understand complex B2B workflows.
Generic dev shops treat each project like a template. We write code for your specific business rules, compliance needs, and integrations.
Our team has delivered 200+ web applications for B2B clients across 50 countries. Average project ships in 12 weeks with fixed pricing.
Generic dev shop vs experienced B2B team
Most development agencies lack the senior talent needed for complex B2B applications.
Generic shops assign junior devs and charge hourly. You pay for their learning curve and end up with unfinished code that doesn't pass compliance.
IRPR assigns senior engineers with 10+ years experience. We give you a fixed price in week 2 and ship production-ready code that passes SOC 2, HIPAA, or PCI audits.

How we build your B2B web app
Our process removes ambiguity and delivers predictable results.
We start with a discovery call to understand your users, workflows, and data sources.
By week 2 we provide a detailed roadmap with fixed price. Then we build in 2-week sprints with weekly demos.
What ships with your B2B web app
Every project includes these deliverables by default.
We ship source code, CI/CD pipelines, and documentation. You own everything.
No black box. You get admin access to all tools.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab
- Stripe integration for billing

- Sentry error tracking configured
- AWS or Vercel infrastructure as code (Terraform)
- Postman collection for all APIs
- Figma design files for every screen
