Top B2B Web App Development StudioDevelopment Studio
We build B2B web apps that handle complex workflows. Fixed price, senior engineers, 8-12 week delivery.
IRPR is a top B2B web app development studio that ships production-grade software for businesses across 50+ countries. We use Next.js, React, Node.js, Python, and PostgreSQL to build web apps that handle complex logic, user roles, and third-party integrations.
Every project starts with a fixed-price Roadmap phase (week 2). From there we deliver a working MVP in 8-12 weeks. Typical budgets range from $80K to $250K. We comply with HIPAA, PCI-DSS, SOC 2, and other industry standards.
We work with CEOs who need a new revenue-generating SaaS platform, CTOs replacing legacy enterprise portals, product managers launching B2B marketplaces, and venture-backed founders building investor-ready MVPs. All come to us because we ship on time and on budget.

Why IRPR is a Top B2B Web App Development Studio
We have shipped over 200 B2B web apps across 50 countries with a 98% on-time delivery rate.
Every web app we build is architected for scale from day one. We use a standardized stack — Next.js, Node.js, PostgreSQL, and AWS — so your project doesn't start from scratch. We also support Python, Go, and React Native when needed.
Our compliance track record includes HIPAA, PCI-DSS, and SOC 2. We have built apps that process millions of transactions per month and store sensitive healthcare data. Every client gets full source code ownership and a 99.9% uptime SLA.
How We Differ from Other Development Studios
Most firms charge by the hour and change scope. We don't.
Generic dev shops often start without a solid roadmap. They bill hourly, add overhead, and deliver late. IRPR fixes all three problems by working on a fixed-price model with a clear Roadmap phase that captures every screen, integration, and data model before any code is written.
Our senior engineers (average 10+ years experience) work in small teams. You get a product manager, a tech lead, and dedicated developers. We communicate daily via Slack and run two-week sprints with demo reviews.
- Hourly billing — no budget certainty
- Junior-heavy teams that miss deadlines
- No compliance expertise
- Scope creep eats your budget
- You own no IP or code
- No ongoing support after launch
- Fixed price from the Roadmap phase
- Senior engineers with 10+ years avg.
- HIPAA, PCI-DSS, SOC 2 compliance built in
- Scope locked in week 2
- Full source code ownership
- 99.9% uptime SLA with managed hosting
Our Process for Building B2B Web Apps
We follow a four-phase framework that guarantees a predictable outcome.
Phase 1 (Idea) is a 2-day workshop where we map user stories, flows, and technical constraints. Phase 2 (Roadmap) produces a detailed document with mockups, data models, API contracts, and a fixed price — you pay only the Roadmap fee to get started.
Phase 3 (Product) is where we build the MVP in 8-12 weeks. We use continuous deployment, automated testing, and weekly demos. Phase 4 (Release) includes production deployment on AWS, CI/CD pipeline, and a 30-day hypercare period.
What You Get When You Hire a Top B2B Web App Development Studio
Every project ships with production-ready deliverables, not just code.
When you work with IRPR, you own everything — source code, designs, documentation, and infrastructure scripts. We set up your AWS account, CI/CD pipelines, and monitoring dashboards before day one of development.
You also get a dedicated product manager, a tech lead, and a QA engineer. We run automated tests (Jest, Cypress) and manual QA on every release. No junior developers write production code.
- Full source code in your GitHub repo
- CI/CD pipeline on GitHub Actions + AWS CodeDeploy
- Sentry error tracking and performance monitoring
- Database schema and migration scripts (PostgreSQL)
- Postman/Insomnia API collection with documentation
- User authentication with Auth0 or Cognito
- Design system (Figma) with component library
- 99.9% uptime SLA with 24/7 incident response
- Stripe integration for subscription billing
- HIPAA/PCI/SOC 2 compliance documentation
