b2b portal development partnerdevelopment partner
We build custom B2B portals for ordering, inventory, and pricing. 8-12 week MVP with a fixed price and no surprises.
IRPR builds custom B2B portals for distributors, manufacturers, and wholesalers. We use React for the frontend, Node.js or Python for the backend, and PostgreSQL or MongoDB for data. Each portal includes role-based access, catalog management, and real-time pricing.
A typical B2B 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 data security. You get source code, CI/CD pipeline, and AWS or Azure infrastructure.
We work with CEOs launching a wholesale channel, CTOs replacing legacy ordering systems, product managers digitizing a distributor network, and operations heads automating procurement. Each buyer needs a portal that works for their specific business rules.

Why you need a b2b portal development partner
A generic website builder won't handle tiered pricing, role-based access, or ERP integration.
A B2B portal is different from a consumer ecommerce site. You need custom pricing per customer, order approval workflows, and integration with your ERP or accounting system. IRPR has built 200+ portals across 50 countries, so we know the patterns that work.
We use a fixed price model based on your Roadmap. In week 2, we define the exact scope, tech stack, and timeline. You get a single quote with no hourly billing. Our average MVP ships in 10 weeks with a 98% on-time rate.
How we build your B2B portal
We follow a 4-phase process: Idea, Roadmap, Product, Release.
Phase 1 (Idea) is a 1-week discovery where we map your business rules, user roles, and integration points. Phase 2 (Roadmap) takes 1 week and produces a detailed scope, wireframes, and a fixed price. Phase 3 (Product) is 8-12 weeks of agile development with weekly demos. Phase 4 (Release) includes deployment, CI/CD setup, and a 30-day warranty.
Every portal ships with source code in your GitHub repo, a CI/CD pipeline on GitHub Actions, Sentry error tracking, and AWS or Azure infrastructure as code. You own everything from day one.
- Hourly billing with no cap
- No fixed timeline
- Generic templates, not custom
- No ERP integration expertise
- You don't see code until launch
- No post-launch support plan
- Fixed price based on Roadmap

Our B2B portal development process
Each phase has a clear output and a go/no-go decision.
We start with a 1-week Idea phase where we interview your stakeholders and review your current ordering process. You get a 3-page document outlining the core workflows and integration needs.
The Roadmap phase produces a detailed spec with wireframes, user stories, and a fixed price. You review and approve before we write a single line of code.
What you get with every B2B portal
Every project ships with these deliverables as standard.
We don't just hand over a zip file. You get a complete production-ready system with monitoring, CI/CD, and documentation. Your team can take over immediately or we can continue on retainer.
All code is in your GitHub repository from the first commit. You own the IP, the domain, and the infrastructure. There is no lock-in.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- AWS or Azure infrastructure as code (Terraform)
- Role-based access control (RBAC)
- Custom pricing engine with tiered discounts
- Order management with approval workflows
- ERP integration (NetSuite, QuickBooks, SAP)
