B2B Portal Development VendorDevelopment Vendor
IRPR builds custom B2B portals for buyer-supplier transactions, order management, and real-time inventory. Our senior engineers deliver a working portal in 8-12 weeks with fixed pricing.
IRPR builds custom B2B portals that connect buyers with suppliers, automate procurement, and handle complex pricing and inventory rules. We use Next.js, Node.js, and PostgreSQL to deliver a portal that works on desktop and mobile from day one.
Clients get a working portal in 8 to 12 weeks. Pricing is fixed between $80K and $250K depending on integrations like ERP, CRM, and payment gateways. We build to PCI-DSS standards if the portal processes payments.
Our buyers are manufacturing supply chain VPs who need supplier self-service, logistics directors who want real-time carrier onboarding, wholesale distributors automating reorder processes, and ecommerce managers consolidating B2B order management.

Why choose IRPR as your B2B portal development vendor
We ship portals that buyers and suppliers actually use.
IRPR has built over 200 products for clients in 50 countries. Our B2B portal projects average 12 weeks from kickoff to launch. We keep 98% of projects on time because we define scope in the Roadmap phase before any code is written.
Every portal we deliver is built by senior engineers with 8+ years of experience. We handle compliance like PCI-DSS for payment modules and HIPAA for healthcare procurement. No junior developers, no offshore teams.
Generic agency vs IRPR as your B2B portal vendor
Most agencies bill hourly and change scope. We do the opposite.
The typical development agency starts with hourly billing and ambiguous requirements. That leads to budget overruns and portals that miss key integrations.
IRPR starts with a fixed-price Roadmap phase. You get a clear project plan, a fixed price, and a delivery date before we build anything.
- Hourly billing with no cap
- Unclear scope that changes mid-project
- No compliance knowledge (HIPAA, PCI, SOC 2)
- Uses pre-built themes and templates
- Slow response times (time zones)
- No post-launch support included
- Fixed price defined in Roadmap phase (week 2)
- Detailed scope document signed by both parties
- Built from scratch with compliance input
- Custom wireframes and prototypes
- Daily async updates on Slack, 6-hour overlap with US time zones
- 12 months of security patches and bug fixes included
Our B2B portal development process
Four phases from concept to launch.
We discovered early that B2B portals fail when requirements are vague. That is why our process starts with a deep discovery phase focused on workflows and data flows.
After the Roadmap, we design the UI and build the portal in 3 sprints. Each sprint ends with a demo so you see real progress.
