Why choose a top B2B portal development firm
A custom B2B portal eliminates manual orders, reduces errors, and drives revenue.
IRPR has built over 200 B2B portals since 2016. Our clients see an average 40% reduction in order processing time and 25% increase in repeat orders within 6 months. Every portal runs on AWS with 99.9% uptime SLA.
We start with a 2-week Roadmap phase to define scope, wireframes, and integrations. Fixed price is locked before any development begins. No hourly billing, no surprises.
How IRPR differs from other agencies
Most dev shops overpromise and underdeliver. IRPR ships on time, on budget, with real code.
Generic firms often quote hourly, scope-creep you, and hand over spaghetti code. IRPR uses a fixed price model and delivers production-ready portals with CI/CD built in.
We assign a senior engineer as your sole point of contact. Our team averages 10+ years experience. Every portal gets automated tests, monitoring, and documentation.
- Hourly billing with no cap
- Scope creep causes budget overruns
- Junior or offshore developers
- No compliance expertise
- Vague timelines + delays
- Source code may be licensed, not owned
- Fixed price locked in Roadmap phase
- Strict scope with clear change process
- Senior engineers only, US-based PM
- HIPAA, SOC 2, PCI-DSS built-in
- 12-14 week delivery guarantee
- Full source code ownership in your repo
Our process for building your B2B portal
We follow a repeatable 4-phase framework that keeps your project on track.
Phase 1: Idea validation and technical audit (week 1). We review your current systems, integrations, and user workflows. Deliverable: a detailed project brief.
Phase 2: Roadmap with wireframes and estimates (week 2). We create a full UI prototype on Figma, backend architecture diagram, and fixed price quote. You approve before a line of code is written.
Phase 3: Product build in 8-10 weeks. Two-week sprints with demos every Friday. We deploy to a staging environment on AWS. You test with real users.
Phase 4: Release and handover (week 12-14). Production deploy, CI/CD pipeline, docs, and training. We support for 30 days post-launch.

Why teams hire us.
Fixed price, no hourly billing
Every B2B portal project gets a fixed price in the Roadmap phase (week 2). No surprise overages, no scope creep invoices. You know the exact cost before a single line of code is written.
Ship in 12 weeks, not 12 months
Our average MVP timeline is 12 weeks from kickoff to production. We use battle-tested templates and reusable components to accelerate development without cutting corners.
Senior engineers only
Every project is led by a US-based senior engineer with 10+ years of experience. No junior developers, no offshore outsourcing. We assign a dedicated architect for your B2B portal.
Full source code ownership
You own every line of code we write. The portal is deployed in your AWS account, and the source code lives in your private GitHub repo. No licensing fees, no vendor lock-in.
Compliance built-in, not bolted on
We have built HIPAA-compliant, SOC 2 Type II, and PCI-DSS Level 1 portals. Our team understands audit requirements and builds security controls from day one.
99.9% uptime SLA
We design for high availability using AWS multi-AZ deployments, load balancing, and auto-scaling. Your B2B portal stays up even during traffic spikes.
