Leading B2B Web App Development DevelopersDevelopment Developers
We build B2B web apps that handle complex workflows and high traffic. 200+ products shipped, 8-12 week MVPs, fixed pricing.
IRPR is a team of senior engineers who build B2B web apps for companies that need reliability, security, and speed. We use Next.js, React, Node.js, Python, and AWS to ship production-ready applications that handle complex business logic, high concurrency, and strict compliance requirements.
Every project starts with a 2-week Roadmap phase where we define the architecture, tech stack, and fixed price. Most MVPs ship in 8-12 weeks. Prices range from $80K to $250K depending on scope. We work under HIPAA, PCI-DSS, SOC 2, and FERPA frameworks.
Our clients are B2B founders who need a scalable platform before Series A, enterprise innovation teams that need a custom portal for partners, and SaaS companies that want to rebuild a legacy app in modern tech without downtime.

Why choose leading B2B web app development developers
IRPR has shipped 200+ B2B web apps for clients in 50+ countries.
We do not use junior developers or offshore teams. Every engineer on your project has 8+ years of experience and has built production B2B systems before. Our senior-only model means fewer bugs, faster delivery, and cleaner code.
Our fixed pricing model removes financial uncertainty. After the 2-week Roadmap phase, you get a fixed quote that does not change. No hourly billing, no surprise invoices, no scope creep charges. This is how leading B2B web app development developers should work.
The IRPR difference for B2B web app development
Most development shops promise quality but deliver scope creep and missed deadlines.
Generic dev shops often assign junior developers, use hourly billing, and have no fixed timeline. They treat your project as one of many, not a priority.
IRPR works differently. We assign a dedicated team of senior engineers, deliver on a fixed timeline, and charge a fixed price. Your project gets the same attention as a $1M enterprise engagement.
- junior developers with 1-2 years experience
- hourly billing with no cap
- no fixed timeline - scope creep is common
- offshore teams with time zone delays
- unclear code ownership
- no compliance expertise
- senior engineers with 8+ years experience
- fixed price after 2-week Roadmap
- 8-12 week MVP delivery guarantee
- US time zone overlap with async-first workflow
- full source code ownership
- HIPAA, PCI-DSS, SOC 2, FERPA compliance built in
How we build your B2B web app
Our process from idea to production takes 10-14 weeks for most projects.
We follow a 4-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a go/no-go decision point. This eliminates wasted time and keeps your budget on track.
The Roadmap phase is critical. In 2 weeks, we define the architecture, tech stack, database schema, API contracts, and a fixed price. You see exactly what you will get before we write a single line of production code.
What ships with every B2B web app
Every project includes production-ready infrastructure and full documentation.
We do not just deliver code. We deliver a complete system that your team can run, monitor, and extend. Everything is documented and automated.
Our standard delivery includes CI/CD pipelines, error tracking, performance monitoring, and security scanning. No surprises after launch.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Staging and production environments on AWS or GCP
- Sentry error tracking and performance monitoring
- Datadog or New Relic infrastructure monitoring
- Automated test suite (unit, integration, e2e)
- Security scan with Snyk or SonarQube
- API documentation with Swagger/OpenAPI
- Database migration scripts and seed data
- Deployment runbook and architecture diagram
