Best B2B Web App Development ServicesWeb App
We build B2B web apps that handle complex workflows and compliance. 200+ products shipped in 12 weeks or less.
IRPR builds B2B web apps for companies that need secure, scalable software. We use React, Next.js, Node.js, Python, and PostgreSQL to deliver production-ready applications. Every project includes CI/CD pipelines, automated testing, and cloud infrastructure on AWS or Azure.
Our process takes 8 to 12 weeks for an MVP. Pricing is fixed and starts at $80K for a standard B2B web app, ranging up to $250K for complex multi-tenant platforms. We comply with HIPAA, PCI-DSS, SOC 2, and FERPA depending on your industry.
We work with CTOs who need to launch a B2B SaaS platform, product managers who want to replace legacy systems, and founders who need a technical co-founder to build their MVP. Each engagement starts with a 2-week Roadmap phase where we define scope, architecture, and a fixed price.

Why IRPR is the best B2B web app development company
We have shipped over 200 B2B web apps for clients in 50 countries. Here is what that experience delivers.
Every B2B web app we build starts with a 2-week Roadmap phase. During this phase, we define the architecture, data model, API contracts, and a fixed price. No surprises. No scope creep. You know exactly what you are getting and what it costs before we write a single line of production code.
Our senior engineers have built B2B web apps for healthcare (HIPAA), fintech (PCI-DSS), and SaaS (SOC 2) clients. We use React, Next.js, Node.js, Python, and PostgreSQL as our core stack. Every project ships with a CI/CD pipeline on GitHub Actions, automated tests, and monitoring via Sentry and Datadog.
How IRPR differs from other B2B web app development agencies
Most agencies bill hourly and change scope mid-project. We do not.
Generic dev shops often start coding without a clear plan. They use junior developers, change requirements, and bill you for every extra hour. The result is a project that goes over budget and misses deadlines. We have seen this happen to dozens of clients who came to us after a failed first attempt.
IRPR uses a fixed-price model based on a detailed Roadmap. We assign senior engineers only. Every project has a dedicated project manager and a technical lead. We ship on time because we plan before we build.
- Hourly billing with no cap
- Junior developers on your project
- Scope changes without price adjustment
- No compliance expertise
- No CI/CD or automated testing
- Code ownership unclear
- Fixed price from the Roadmap phase
- Senior engineers only (8+ years experience)
- Scope locked after Roadmap
- HIPAA, PCI-DSS, SOC 2 compliance built in
- CI/CD pipeline, automated tests, monitoring
- Full code ownership transferred to you
Our B2B web app development process
We follow a 4-phase process that takes 8 to 12 weeks from idea to launch.
Phase 1 is the Roadmap. In 2 weeks, we define the product scope, user flows, data model, and tech stack. You get a detailed document and a fixed price. Phase 2 is the build. Our senior engineers code the web app in 6 to 10 weeks, depending on complexity. We use React, Next.js, Node.js, and PostgreSQL.
Phase 3 is the release. We deploy to AWS or Azure, set up monitoring with Sentry and Datadog, and run load tests. Phase 4 is the handoff. You get full source code, documentation, and a 30-day warranty. We also offer ongoing maintenance if you need it.
What ships with every B2B web app
Every project includes these deliverables by default. No add-ons, no extra fees.
We believe in shipping production-ready software. That means your B2B web app comes with everything needed to run in the real world. You do not need to hire another team for DevOps, testing, or compliance.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Automated unit and integration tests (80%+ coverage)
- Sentry error tracking and monitoring
- Datadog performance monitoring
- Deployment to AWS or Azure
- SSL certificate and custom domain setup
- Admin dashboard with user management
- API documentation (Swagger/OpenAPI)
- 30-day post-launch warranty
