Why choose an experienced B2B web app development vendor
Building a B2B web app requires more than just code. It demands compliance, scalability, and real business logic.
IRPR has shipped over 200 B2B web apps across 50 countries. Our team of senior engineers averages 10+ years of experience. We use proven architectures like microservices and event-driven systems to handle growth from day one.
Every project includes automated testing, CI/CD pipelines, and monitoring with Sentry and Datadog. We write code that passes SOC 2 audits and HIPAA privacy requirements. Your data stays secure and your app stays online at 99.9% uptime.
The difference between generic dev shops and IRPR
Most development agencies promise results but deliver scope creep and technical debt. IRPR is different.
Generic dev shops often use junior developers, charge hourly, and hand off code without documentation. You end up with bugs, slow performance, and no way to maintain the app.
IRPR assigns senior engineers only, gives a fixed price upfront, and delivers a fully documented production app. We include performance monitoring, error tracking, and deployment scripts in every project.
- Junior developers with 2 years experience
- Hourly billing with no cap
- No compliance testing (HIPAA, SOC 2)
- Code without tests or documentation
- Manual deployment and no monitoring
- No post-launch support plan
- Senior engineers with 10+ years each
- Fixed price from Roadmap phase
- Built-in compliance for HIPAA, SOC 2, PCI
- 100% test coverage and full documentation
- CI/CD pipeline with Sentry and Datadog
- 30-day post-launch support included
How we build your B2B web app in 12 weeks
Our process moves from idea to production in four phases. Each phase has clear deliverables and a fixed timeline.
We start with a two-week Discovery phase where we map your domain, user flows, and technical constraints. Then we deliver a Roadmap with a fixed price and timeline.
The Build phase runs 6-8 weeks with weekly demos. We deploy to staging after week 4 and production by week 12. You own the code from day one.
What ships with every B2B web app project
You get more than a working application. Every project includes the full operational setup to run it in production.
IRPR treats every project as a product, not a prototype. We deliver everything you need to maintain, scale, and monitor your app after launch.
All code is stored in your private GitHub repository. We set up CI/CD, error tracking, and uptime monitoring. You also get architecture diagrams and a deployment runbook.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions
- Sentry error tracking and performance monitoring
- Datadog dashboards for uptime and latency
- Unit and integration tests (80%+ coverage)
- API documentation with Swagger or Postman
- Architecture diagrams (C4 model)
- Deployment runbook and incident response plan
- Admin panel for managing users and data
- 30-day post-launch support and bug fixes
