Why choose an experienced B2B web app development agency
B2B web apps require deep industry knowledge and compliance expertise that generalist agencies lack.
IRPR has shipped 200+ web apps for B2B clients in healthcare, fintech, and SaaS. We know how to handle multi-tenant architecture, role-based access, and integrations with Salesforce, Stripe, and Twilio. Every project includes a security review and load testing.
Our team of senior engineers works across time zones with 4 hours of daily overlap with US clients. We use agile sprints, weekly demos, and a shared Slack channel. You get a fixed price quote after the roadmap phase, not before.
How IRPR differs from other agencies
Most agencies bill hourly and change scope. IRPR does the opposite.
Generic dev shops start coding with a vague estimate and bill you for every extra meeting. They use junior developers and outsource testing. You never know the total cost until the project is done.
IRPR gives you a fixed price after a 2-week roadmap phase. You work with senior engineers who have 10+ years of experience. We write tests, deploy to production, and hand over full ownership of the code.
- Hourly billing with no cap
- Junior developers on your account
- No compliance expertise
- Scope creep every sprint
- No documentation after delivery
- Code ownership unclear
- Fixed price after roadmap phase
- Senior engineers only (10+ years)
- HIPAA, PCI, SOC 2 built in
- Scope locked in roadmap
- Full documentation and tests
- You own all source code
Our B2B web app development process
We follow a structured 4-phase process that de-risks your project.
Phase 1 is the Idea phase where we define the problem and target users. Phase 2 is the Roadmap phase where we create a detailed spec, wireframes, and a fixed price quote. This takes 2 weeks and costs $5K.
Phase 3 is the Product phase where we build your MVP in 8-12 weeks using agile sprints. Phase 4 is the Release phase where we deploy to production, set up monitoring, and hand over the code. You get a working app with CI/CD and error tracking.
What ships with your B2B web app
Every project includes more than just code. You get a production-ready system.
When we deliver your web app, you get the source code in your own GitHub repository, a CI/CD pipeline using GitHub Actions, and a staging environment for testing. We also set up Sentry for error tracking and Datadog for performance monitoring.
Documentation includes architecture diagrams, API docs, and a deployment guide. You get a 30-day warranty for any bugs. After that, we offer maintenance at a fixed monthly rate.
