Leading B2B Web App Development AgencyWeb App
Build scalable web apps that drive revenue. IRPR delivers in 8-12 weeks with a fixed price and full code ownership.
IRPR builds enterprise-grade B2B web applications using React, Node.js, Python, and PostgreSQL on AWS. We focus on products that handle complex business logic, multi-tenant architecture, and high-volume data processing.
A typical B2B web app ships in 8-12 weeks with a fixed price between $80,000 and $250,000. Every project adheres to SOC 2, HIPAA, or PCI standards from day one, so you pass audits without rework.
CEOs scaling a B2B platform hire us to de-risk delivery. CTOs use us to augment their team with senior talent. Product managers launch MVPs that actually work in production. Enterprise IT leaders modernize legacy systems without hiring a full internal team.

Why Choose a Leading B2B Web App Development Agency
Numbers prove experience. IRPR has shipped 200+ web applications for clients in 50 countries.
Our average project takes 12 weeks from idea to release. 98% of those projects delivered on time and on budget. We keep teams small — 3 to 5 senior engineers per project — which removes communication overhead.
Every app we build includes automated CI/CD pipelines, monitoring with Sentry and Datadog, and load testing before launch. That means 99.9% uptime from day one for our clients.
How We Differ from Other Development Agencies
Most agencies bill hourly and change requirements. IRPR quotes a fixed price after a 2-week Roadmap.
Generic dev shops often start building before the requirements are clear. That leads to scope creep, surprise invoices, and software that doesn't match the market need. They use junior developers to cut costs, which adds technical debt.
IRPR assigns only senior engineers who average 10+ years of experience. We document everything in a Roadmap before we write a single line of production code. You approve the plan and the price upfront.
- No fixed price until the end
- Uses junior and mid-level devs
- Starts coding without a detailed spec
- No built-in compliance (HIPAA, PCI, SOC 2)
- You don't always own full source code
- Timeline slips by 30-50% on average
- Fixed price after a 2-week Roadmap
- Senior engineers only (10+ years avg)
- Detailed Roadmap approved before production
- Compliance built into every app (HIPAA, PCI, SOC 2)
- You own 100% of the source code
- 8-12 week delivery with 98% on-time record
Our Process for Building B2B Web Apps
Four phases turn your idea into a production-grade web app. Each phase has a fixed deliverable.
We don't start with a blank canvas. The Idea phase validates the concept against market data and technical feasibility. You get a one-page product brief with feature priorities and user flows.
In the Roadmap phase (week 2), we produce a full technical specification, wireframes, and a fixed-price contract. You approve the Roadmap, and we move into Product — 6-10 weeks of iterative development with weekly demos.
What Ships with Every B2B Web App
Every project includes production infrastructure, not just code.
We treat DevOps as part of the build, not an afterthought. Your app deploys to AWS with auto-scaling, encrypted data at rest, and a fully managed database. You get alerts and dashboards from day one.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions and Docker
- AWS environment with CloudFormation templates
- Sentry for error tracking
- Datadog for performance monitoring
- SSL certificate and custom domain setup
- Automated backup and disaster recovery plan
- Postman collection for all APIs
- User documentation and admin guide
- 30-day post-launch warranty with bug fixes
