Why choose an expert B2B web app development company
Building a B2B web app is different from consumer apps. You need multi-tenant architecture, compliance, and integrations from day one.
IRPR has shipped over 200 B2B web apps across 50 countries. Our average MVP takes 12 weeks from kickoff to launch. We use a fixed-price model so you know the cost before we write a line of code. Every project includes a 2-week Roadmap phase where we define the architecture, data model, and API contracts.
Our team includes senior engineers who have built systems for HIPAA, PCI-DSS, and SOC 2 compliance. We use React, Next.js, Node.js, and PostgreSQL as our default stack. If you need Python, Go, or .NET, we can adapt. We also handle DevOps with AWS, Docker, and CI/CD pipelines.
How IRPR differs from other B2B web app development companies
Most agencies bill hourly and change scope. IRPR gives you a fixed price and a clear timeline.
We have seen projects fail because of vague requirements and endless revisions. That is why we start every engagement with a 2-week Roadmap phase. You get a detailed specification, a fixed price, and a delivery date. No surprises.
Our engineers work in overlapping time zones with US-based clients. We use Slack, Linear, and weekly demos to keep you informed. You own the source code, the IP, and the deployment. We do not lock you into a long-term contract.
- Hourly billing with no cap
- Vague requirements that change mid-project
- Junior developers learning on your dime
- No compliance experience (HIPAA, PCI-DSS)
- Code ownership is unclear
- Long contracts with exit fees
- Fixed price from the Roadmap phase
- Detailed spec before any code is written
- Senior engineers only (8+ years experience)
- Built-in compliance for healthcare, fintech, SaaS
- You own all code and IP
- No long-term contracts. Month-to-month after launch
Our process for building your B2B web app
We follow a four-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables.
The Idea phase is a free discovery call where we discuss your business goals, target users, and technical constraints. We decide if we are a good fit. If yes, we move to the Roadmap phase.
The Roadmap phase takes 2 weeks. We produce a detailed specification with wireframes, data models, API endpoints, and a fixed price quote. You approve the spec, and we start building. The Product phase takes 8-12 weeks for an MVP. We ship working software every 2 weeks. The Release phase includes deployment, monitoring, and a 30-day warranty.
What ships with every B2B web app
Every project includes these deliverables by default. No hidden fees or optional extras.
We believe in transparency. When we deliver your B2B web app, you get everything you need to run it independently. No vendor lock-in.
Our standard delivery includes source code, CI/CD pipeline, monitoring, and documentation. We also provide a 30-day post-launch support period.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Deployed on AWS with auto-scaling and load balancing
- Sentry error tracking and Datadog monitoring
- PostgreSQL database with automated backups
- API documentation (OpenAPI/Swagger)
- Admin dashboard for managing users and data
- Unit tests and integration tests (80%+ coverage)
- SSL certificate and HTTPS enforcement
- 30-day post-launch warranty for bug fixes
