Why Choose an Experienced B2B Portal Development Vendor
IRPR has shipped 200+ products across 50 countries. We know what makes a B2B portal work.
We built a B2B ordering portal for a medical supply distributor that reduced order processing time by 60%. The portal handles 500+ SKUs with tiered pricing for 2000+ buyers. It syncs inventory with their ERP every 15 minutes using a custom Node.js connector.
Another client was a food wholesaler with 3000+ restaurant customers. Their old portal could not handle peak orders. We rebuilt it in React with a PostgreSQL backend. The new portal processes 10,000 orders per day with 99.9% uptime on AWS.
The Difference Between IRPR and Other B2B Portal Vendors
Most agencies bill hourly and deliver late. IRPR gives you a fixed price and on-time delivery.
We have seen generic dev shops promise a B2B portal in 6 months and deliver in 12. They use junior developers and cut corners on security. Their portals crash under load and cost twice the original quote.
IRPR assigns senior engineers only. Every engineer has 10+ years of experience. We scope your portal in the Roadmap phase (week 2) and give you a fixed price. No surprises. No scope creep.
- hourly billing with no cap
- junior developers with 2 years experience
- no compliance knowledge (PCI, SOC 2)
- portals crash at 1000 concurrent users
- no deployment or monitoring setup
- you own nothing until final payment
- fixed price from the Roadmap phase
- senior engineers with 10+ years experience
- built-in PCI-DSS and SOC 2 compliance
- portals handle 10,000+ concurrent users
- full AWS deployment with CI/CD
- source code in your repo from day one
How We Build Your B2B Portal in 12-14 Weeks
Our process is designed to get your portal live fast without sacrificing quality.
We start with a 2-week Roadmap phase. We map out user roles, data models, and integrations. You get a fixed price and a detailed timeline before we write a single line of code.
Then we build the MVP in 8-12 weeks. We use React for the frontend, Node.js for the API, and PostgreSQL for the database. We deploy on AWS with auto-scaling and CI/CD pipelines.
What Ships With Your B2B Portal
Every portal includes these deliverables by default. No hidden costs.
We do not just hand over code. We give you a fully deployed, monitored, and documented portal. Your team can start using it on day one.
We also provide a 30-day warranty. If anything breaks, we fix it for free. After that, we offer maintenance at a fixed monthly rate.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- AWS deployment with auto-scaling
- PostgreSQL database with backups
- Sentry error tracking and monitoring
- Stripe payment integration (if needed)
- Role-based access control (admin, buyer, supplier)
- Mobile responsive UI built with React
- API documentation in Swagger
- 30-day post-launch warranty
