Why you need an experienced B2B web app development partner
Building a B2B web app is different from consumer apps. You need compliance, integrations, and reliability from day one.
B2B web apps handle sensitive data, complex user roles, and third-party integrations. A generic agency might build a pretty UI but miss audit logs, SSO, or data encryption. IRPR has shipped 200+ B2B products across 50 countries. We know what enterprise buyers expect.
Our team uses React, Next.js, Node.js, and PostgreSQL as default stack. For compliance, we add encryption at rest, role-based access, and automated backups. Every project includes a CI/CD pipeline on GitHub Actions and error tracking with Sentry.
How IRPR differs from other development partners
Most agencies bill hourly and change scope. IRPR gives you a fixed price and a clear roadmap.
We start every engagement with a 2-week Roadmap phase. You pay a fixed fee ($5K-$15K) and get a detailed spec, wireframes, tech stack, and a fixed price for the full build. No surprises.
Our senior engineers work directly with your team. We use daily standups, weekly demos, and a shared Jira board. You see progress every week. We ship code to your repo from day one.
- Hourly billing with no cap
- Scope creep without change orders
- Junior developers on your project
- No compliance expertise
- Code stays on their servers
- No post-launch support
- Fixed price from Roadmap phase
- Scope locked in week 2
- Senior engineers only (8+ years)
- HIPAA, PCI, SOC 2 built in
- Source code in your repo day one
- 12 months of support included
Our process for building your B2B web app
We follow a 4-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables.
Phase 1 (Idea) takes 1 week. We validate your concept, identify risks, and define the core feature set. Phase 2 (Roadmap) takes 2 weeks. We produce a detailed spec, wireframes, tech stack, and a fixed price quote.
Phase 3 (Product) takes 8-12 weeks. We build the MVP in sprints, with weekly demos and continuous deployment. Phase 4 (Release) includes load testing, security audit, and deployment to production. We monitor for 30 days post-launch.
What ships with every B2B web app
Every project includes production-ready infrastructure, not just code.
We don't hand you a zip file. You get a fully deployed app with CI/CD, monitoring, and documentation. Your team can take over maintenance immediately.
All code is in your GitHub repo from day one. We use Terraform for infrastructure, Docker for containers, and GitHub Actions for CI/CD. Sentry tracks errors, Datadog monitors performance.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Docker containers for local dev
- Staging and production environments on AWS
- Sentry error tracking
- Datadog performance monitoring
- PostgreSQL database with automated backups
- SSL certificate and custom domain
- API documentation (Swagger/OpenAPI)
- 12 months of support and maintenance
