Why Choose a Senior B2B Web App Development Firm
Hiring senior engineers directly saves you time, money, and rework.
Most development shops staff projects with a mix of junior and mid-level developers. At IRPR, every engineer has a decade or more of experience. That means fewer bugs, faster decisions, and architecture that scales from day one.
We have shipped over 200 B2B web apps across 50+ countries. Our process reduces time-to-market by 30% compared to traditional agencies. Fixed pricing eliminates scope creep and budget surprises.
Senior B2B Web App Development Firm vs. Generic Dev Shop
The difference is experience, process, and outcome.
Not all development firms build B2B web apps the same way. Generic shops treat every project like a commodity. Senior engineers deliver architecture that anticipates growth.
IRPR's approach is built on 12 years of shipping production software. We focus on your business logic, not boilerplate setup. Every project includes CI/CD, monitoring, and security from sprint one.
- Junior-heavy teams with high turnover
- Hourly billing with surprise overruns
- No compliance experience (HIPAA, PCI)
- Waterfall handoffs and slow feedback
- Generic boilerplate code you pay for twice
- No post-launch support without retainer
- Senior engineers only (10+ years each)
- Fixed price after Roadmap phase (week 2)
- Built-in HIPAA, PCI-DSS, SOC 2 compliance
- Agile sprints with weekly demos
- Every line of code written for your specific use case
- 3 months of post-launch support included
How We Build Your B2B Web App in 12 Weeks
Our framework delivers a production-ready MVP fast.
We use a four-phase process: Idea, Roadmap, Product, Release. Each phase has clear milestones and fixed deliverables. You see working software every two weeks.
From discovery to deployment, your senior team works async-first with daily overlap during your business hours. We use Notion for specs, Linear for tasks, and Slack for daily communication.
What Ships with Your B2B Web App
You get more than code. You get a launch-ready system.
Every project includes all the infrastructure and tooling needed to run in production. We hand over full ownership at launch.
Our checklist ensures nothing is forgotten. From CI/CD to monitoring, every deliverable is documented and tested.

- PostgreSQL database with migration scripts
- Unit tests with Jest and integration tests with Cypress
- API documentation in Swagger/OpenAPI
- Deployment to AWS (ECS or Lambda) with auto-scaling
- Sentry error tracking and CloudWatch logging
