Professional B2B Web App Development ConsultantsDevelopment Consultants
We build business-grade web applications for B2B companies. Get a fixed-price MVP in 8-12 weeks with senior engineers only.
IRPR is a team of senior engineers who act as professional B2B web app development consultants. We build custom web applications using React, Next.js, Node.js, PostgreSQL, and AWS — delivering production-ready code in 8-12 weeks.
Every project starts with a 2-week Roadmap phase that locks in the scope, timeline, and fixed price ($80K-$250K for a typical MVP). We handle compliance like SOC 2, HIPAA, and PCI-DSS from day one, so your B2B app is audit-ready.
Our clients include CTOs at Series A B2B SaaS companies who need to ship fast without hiring in-house, product directors at enterprises who want a dedicated consulting team, founders who need technical co-founder-level guidance, and VP of Engineering who need to scale their platform without overhead.

Why hire professional B2B web app development consultants?
Our team has shipped 200+ products for B2B companies worldwide, with a 98% on-time delivery rate.
Generic development shops treat every project the same. We bring deep B2B domain expertise — from multi-tenant architecture to role-based access control. We use React, Next.js, and Node.js to build apps that scale with your business.
We also bake compliance into the build. SOC 2, HIPAA, PCI-DSS — we have implemented all three in production. That means no retrofitting security later, and no surprise audit failures.
Professional B2B web app consultants vs. generic dev shops
Not all developers understand B2B workflows like subscription billing, tenant isolation, and compliance.
Generic dev shops often treat complex B2B apps like simple landing pages. They skip architecture planning, use junior developers, and charge by the hour — leading to budget overruns and technical debt.
IRPR treats each engagement as a consulting partnership. We assign senior engineers only, create a detailed Roadmap (week 2), and lock the price before any code is written. The result is predictable delivery and production-quality code.
- No upfront architecture review
- Hourly billing with creeping scope
- Junior developers learning on your project
- No compliance expertise
- One-size-fits-all boilerplate code
- No post-launch support plan
- 2-week Roadmap with architecture document
- Fixed price locked at Roadmap sign-off
- Senior engineers with 10+ years experience
- SOC 2, HIPAA, PCI-DSS built in
- Custom code tailored to your workflows
- Ongoing maintenance and 24/7 monitoring
Our consulting process for B2B web apps
From idea to production in 8-12 weeks — with a clear phase for every stage.
We start with a discovery week where we interview stakeholders, map processes, and define success metrics. This feeds into a Roadmap document (week 2) that outlines the entire scope, tech stack, tests, and compliance checklist.
The build phase is divided into 2-week sprints. You see working software every sprint. We handle deployment, monitoring (Sentry, DataDog), and security testing. After launch, we provide a 30-day hypercare period.
What ships with your B2B web app
Every project comes with a set of production essentials — no optional extras.
We don't just hand over code. We give you the entire infrastructure and tooling to run and maintain the app yourself. All repos, CI/CD pipelines, and monitoring are configured and documented.
If you need ongoing maintenance after the project, we offer retainer contracts starting at $5K/month. But you own everything, so you can also hand it off to your internal team or another vendor.
- Full source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Staging environment on AWS ECS
- Automated test suite (unit + integration + e2e)
- Architecture and API documentation (OpenAPI 3.0)
- Security audit report with penetration test results
- Sentry error tracking and PagerDuty alerting
- CloudWatch dashboards for performance monitoring
- Post-launch knowledge transfer session (recorded)
- 30-day hypercare with 4-hour response SLA

Why teams hire us.
Senior engineers only
Every developer on your project has 10+ years experience and has shipped at least 5 B2B products. No junior developers, no learning curve on your time.
Fixed price, not hourly
You get a fixed price after the Roadmap phase (week 2). No hourly billing, no surprise invoices. If we miss the quote, we eat the cost — that has never happened in 200+ projects.
8-12 week MVP timeline
We design the build phase to ship a working MVP in 8-12 weeks. This is achievable because we use proven patterns, reusable components, and automated CI/CD.
Compliance built in, not bolted on
SOC 2, HIPAA, PCI-DSS, and FERPA are part of our architecture from day one. We have passed audits for 30+ clients — you get the same playbook.
Full code ownership
You own all source code, IP, and infrastructure credentials. No locked-in licenses, no recurring royalties. You can deploy with any team at any time.
We ship, then you iterate
After launch we ship a full handoff package: architecture docs, runbooks, and a recorded knowledge transfer. Then you can build on top or hand to your internal team.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
