Why choose IRPR as your expert B2B web development partner
We deliver production-ready B2B web applications on time and on budget.
IRPR has shipped over 200 products for B2B companies across 50 countries. Our average delivery time is 12 weeks for a fully functional MVP with all integrations, authentication, and DevOps tooling. We work with a fixed price agreed in the Roadmap phase (week 2), so you never pay for overruns.
Every project includes compliance with SOC 2, PCI-DSS, or HIPAA where needed. Our senior engineers have built platforms that process millions of transactions per month with 99.9% uptime. You get full source code ownership and a CI/CD pipeline that runs on GitHub Actions.
Generic dev shops vs. an expert B2B web development partner
Not every agency can handle B2B complexity. Here is the difference.
B2B web applications require multi-tenant architecture, role-based access, complex integrations, and compliance from day one. Generic dev shops often cut corners or assign junior developers. IRPR assigns senior engineers only and follows a proven 4-phase process.
We start with an Idea phase (1 week) to validate requirements, then a Roadmap phase (1 week) to define scope and fixed price. The Product phase (8-12 weeks) builds the MVP, and the Release phase deploys it with full monitoring and documentation.
- Hourly billing with no cap
- Junior developers on your project
- No compliance experience
- No DevOps or CI/CD setup
- Code ownership unclear
- No post-launch support
- Fixed price from week 2
- Senior engineers with 10+ years exp
- SOC 2, PCI-DSS, HIPAA built-in

How IRPR delivers as your expert B2B web development partner
Our 4-phase process ensures no surprises and a product that ships.
Each engagement follows a structured but flexible process. We start by understanding your users, workflows, and compliance needs. Then we create a detailed Roadmap with wireframes, tech stack decisions, and a fixed price before any code is written.
During the Product phase, we build in 2-week sprints with demo reviews. You see working software every sprint. The Release phase includes load testing, security audit, and deployment to production with monitoring and alerts.
