How IRPR delivers the best B2B portal development
Every B2B portal we build starts with a clear roadmap and ends with a live product your partners will use.
IRPR has shipped over 200 B2B portals for companies in manufacturing, distribution, and healthcare. Our senior engineers average 8 years of experience and never use offshore junior talent.
Every portal includes automated CI/CD pipelines, Sentry error monitoring, and a 1-year warranty. We deliver 98% of projects on time and at the fixed price agreed in week 2.
Why IRPR is different from other B2B portal development firms
Most development shops bill hourly and miss deadlines. IRPR fixes both problems.
We meet hundreds of buyers who lost time and money with shops that never shipped. They had no fixed price, no clear timeline, and no compliance expertise.
IRPR reverses that pattern. You get a fixed quote, a weekly demo, and full code ownership from day one. Our portals are built to pass HIPAA, PCI-DSS, and SOC 2 audits.
- Hourly billing with no ceiling
- Timeline slips by months
- No knowledge of HIPAA or PCI-DSS
- Weekly status emails, no demo
- Code is held hostage
- Zero post-launch support
- Fixed price from Roadmap phase
- 8-12 week delivery commitment
- HIPAA, PCI-DSS, SOC 2 built-in
- Weekly live demo of working software
- Full code in your GitHub repo
- 1-year warranty and 24/7 support
How we build your B2B portal in 4 phases
Our process turns your idea into a working portal in under 12 weeks.
Each phase has a fixed deliverable and cost. You see progress every week and can change direction without penalty.
We use React, Node.js, GraphQL, and PostgreSQL by default because they give the fastest time to market and highest developer productivity.

- Order and invoice workflow with Stripe/PayPal integration
- Automated daily database backups to S3
- Readme file with local setup instructions and architecture diagram
