B2B Portal Development AgencyDevelopment Agency
We build custom B2B portals that connect buyers, suppliers, and distributors. Launch your portal in 8-12 weeks with a fixed price starting at $80K.
IRPR builds B2B portals for companies that need to manage orders, invoices, and inventory across their partner networks. We use React, Node.js, PostgreSQL, and cloud-native infrastructure to create portals that scale.
Each portal ships in 8-12 weeks with a fixed price between $80K and $250K. We handle PCI-DSS compliance for payment processing and SOC 2 for enterprise data security.
We work with three buyer types: procurement directors at mid-market manufacturers who want to digitize their supplier network, VP of Sales at wholesale distributors who need a self-service ordering portal, and CTOs at SaaS companies building a partner portal for resellers.
Types of software we ship.
Supplier portal
A portal where suppliers submit quotes, manage purchase orders, and track payments. Integrates with ERP systems like SAP or NetSuite.
Vendor portal
Vendors onboard themselves, upload catalogs, and receive automated RFQs. Connects to Salesforce for sales team visibility.
Distributor portal
Distributors place bulk orders, check real-time inventory, and generate invoices. Built with Next.js and Stripe for payments.
Partner portal
Channel partners access co-branded marketing assets, submit leads, and track commissions. Uses Auth0 for role-based access.
Customer portal
Customers log in to view order history, reorder products, and open support tickets. Integrates with Zendesk for ticket management.
Dealer portal
Dealers manage their inventory, submit warranty claims, and access training materials. Built on AWS with auto-scaling for peak periods.
Wholesale portal
Wholesale buyers see tiered pricing, min order quantities, and place orders that sync to Shopify admin. Uses GraphQL for fast queries.

Why businesses build custom B2B portals
A custom portal eliminates manual order processing and reduces errors by 80%.
IRPR builds portals that replace email and phone order management. One client reduced their order-to-fulfillment time from 3 days to 4 hours using a React-based supplier portal.
Another manufacturer saw a 40% increase in repeat orders after launching a distributor portal with automated pricing tiers. We design for adoption with clean UX and mobile-first interfaces.
How IRPR differs from generic web development shops
Most agencies build portals that are hard to maintain and scale. IRPR delivers production-ready code with compliance built in.
Generic shops often start with hourly billing and no fixed timeline. You get a portal that works now but breaks when you add 100 new suppliers.
IRPR writes modular code with automated tests and CI/CD. We include security review, load testing, and documentation in every project.
- Hourly billing with no cap
- No compliance knowledge
- Monolithic code hard to extend
- No automated testing
- Handoff with no documentation
- Shared hosting not designed for scale
- Fixed price from day one
- SOC 2 and PCI-DSS compliance built in
- Microservices or modular architecture
- CI/CD with automated test suite
- Full production runbook and docs
- Infrastructure as code on AWS/GCP
Our process for building your B2B portal
We ship an MVP in 8-12 weeks using a proven four-phase framework.
Each phase has clear deliverables and a fixed price. You see working software every two weeks.
We use the same process for every portal, regardless of industry or complexity.
What ships with your portal
You get a production-ready system, not just a prototype.
Every portal includes infrastructure setup, security hardening, and ongoing monitoring. Nothing is left for later.
We transfer full ownership of all code, repositories, and infrastructure configurations at the end.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions with automated tests
- Infrastructure as code on AWS (CloudFormation or Terraform)
- Role-based access control with Auth0 or Okta
- Payment integration with Stripe or Braintree (PCI-compliant)
- Order management system with real-time inventory sync
- Invoice generation and PDF download
- Analytics dashboard (custom or using Metabase)
- Sentry error tracking and Datadog monitoring
- Complete runbook for operations team
