Why hire B2B web app development consultants
Building a B2B web app in-house takes too long and costs too much.
IRPR is a team of senior developers who have shipped over 200 products across 50 countries. We build custom B2B web apps using React, Node.js, and PostgreSQL. Our fixed-price model means you know the cost from week 2.
We deliver in 8-12 weeks with a full CI/CD pipeline, comprehensive documentation, and 99.9% uptime SLA. Every project includes a dedicated project manager and regular demo sessions.
The difference between a dev shop and an expert consultant
Not all agencies handle B2B complexity the same way.
Generic dev shops often give vague estimates and no compliance support. They outsource work, skip documentation, and charge hourly. That leads to cost overruns and missed deadlines.
IRPR works as your dedicated consultant. We assign senior engineers only, produce a detailed Roadmap in week 1, and lock the price. You get full code ownership, compliance-ready architecture, and a deployment runbook.
- Hourly billing with no cap
- No compliance or security review
- Junior developers or offshore teams
- No written architecture document
- Delayed delivery without accountability
- No post-launch support included
- Fixed price from week 2
- Built-in HIPAA, SOC 2, PCI-DSS compliance
- Senior engineers only (7+ years average)
- Full architecture and API docs delivered
- 8-12 week timeline with weekly demos
- 2 months of free support after launch
Our process for building your B2B web app
We use a 4-phase approach that guarantees speed and clarity.
Every project starts with a 2-week Roadmap phase where we define scope, tech stack, and a fixed price. Then we design, build, and ship your app in 8-12 weeks total.
You get a dedicated project manager and access to a private Slack channel. We deploy to staging within 4 weeks so you can see progress early.
What you get with every B2B web app project
Every project ships with these deliverables included.
We believe in full transparency. You own everything: source code, documentation, and infrastructure. No lock-in, no hidden fees.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline on GitHub Actions or AWS CodePipeline
- Sentry error tracking and performance monitoring
- Unit tests and integration tests (coverage > 80%)
- API documentation generated with Postman or Swagger
- Deployment runbook and architecture diagram
- SSL certificates and HTTPS configuration
- Automated nightly backups and recovery plan
- 2 months of post-launch support
- Direct Slack access to the entire team
