Why choose IRPR as your affordable B2B web app development firm
We have shipped over 200 B2B web applications across 50+ countries.
Every project starts with a 1-2 week sprint called Discovery. We map your workflows, identify integrations (Stripe, HubSpot, Salesforce), and define the data model. By week 2 you get a Roadmap with a fixed price quote.
Our engineers have built compliance-heavy systems for healthcare (HIPAA) and fintech (PCI-DSS). We include penetration testing, audit logs, and encryption by default. You own the full source code from day one.
What makes IRPR different from other web development firms
Most dev shops sell hours. We sell a finished product.
Generic agencies start with a vague SOW and bill hourly. If the project scope changes, the price goes up. You don't know the final cost until the end.
IRPR works on a fixed-price model. After the Roadmap phase, every feature is scoped and priced. No surprise invoices. We also guarantee 1-2 week sprint cycles so you see progress weekly.

Our process for building your B2B web app
We follow a repeatable 4-phase process to take your idea to a live product.
Phase 1 (Idea) is a deep-dive workshop to define user stories and wireframes. Phase 2 (Roadmap) produces a technical blueprint and fixed-price quote. Phase 3 (Build) runs in 2-week sprints with demos after each. Phase 4 (Release) deploys to production on AWS or your own infrastructure.
Throughout the project you communicate with the actual engineers via Slack and weekly video calls. Our async-first workflow means we can work across time zones without delays.
What you get when you hire IRPR
Every project ships with these deliverables included in the fixed price.
You receive the complete source code from day one. No licensing fees, no ongoing vendor lock-in. Our CI/CD pipeline runs on GitHub Actions and deploys to AWS with zero-downtime releases.
We also include 2 weeks of post-launch support to fix any bugs and help your team ram up. After that you can continue with a monthly retainer or take the code in-house.

What we ship in this practice.
SaaS customer portal

A logistics firm wanted to automate PO approvals for 200+ vendors. We delivered a React app with Node.js and SendGrid integration. Approval time dropped from 3 days to 4 hours.
Healthcare provider portal
A telemedicine platform needed HIPAA-compliant patient intake forms. We used React, Node.js, and AWS with encrypted storage. Patient onboarding time reduced by 50%.

Compliance ready
We have delivered HIPAA, SOC 2, and PCI-DSS compliant applications. Our engineers implement encryption, audit logs, and access controls from the start, not as a retrofit.

12 week guarantee
98% of our projects ship on time or ahead. If we miss the timeline, we discount the next sprint. The average MVP is delivered in 10 weeks, not months.
