Why hire senior b2b web app development consultants
Building a B2B web app is different from consumer apps. You need senior engineers who understand multi-tenancy, compliance, and enterprise integrations.
IRPR's senior b2b web app development consultants have shipped over 200 products. We work with React, Next.js, Node.js, Python, and PostgreSQL. Every project includes CI/CD pipelines, automated testing, and cloud deployment on AWS or GCP.
We have built B2B web apps for healthcare (HIPAA), fintech (PCI-DSS), and SaaS (SOC 2). Our team handles complex integrations with Salesforce, Stripe, HubSpot, and custom APIs. We deliver production-ready code in 8-12 weeks.
How IRPR differs from other B2B web app consultants
Most agencies bill hourly and change scope mid-project. IRPR works differently.
We give you a fixed price after a 2-week Roadmap phase. No hourly billing, no surprise invoices. You know the cost before we write a line of production code.
Our senior b2b web app development consultants are all senior engineers with 10+ years of experience. We do not outsource work. Every line of code is written by our team in the US and Europe.
- Hourly billing with no cap
- Junior developers on your project
- Scope creep leads to cost overruns
- No compliance expertise
- Code quality varies project to project
- You own nothing after delivery
- Fixed price after Roadmap phase
- Senior engineers only (10+ years)
- Scope locked in week 2
- HIPAA, PCI-DSS, SOC 2 built in
- Consistent code standards across all projects
- You own 100% of the source code
Our process for building your B2B web app
We follow a 4-phase process that takes 8-12 weeks from idea to production.
Phase 1 is the Idea phase where we align on goals and constraints. Phase 2 is the Roadmap phase where we define the scope, tech stack, and fixed price. Phase 3 is the Product phase where we build the MVP. Phase 4 is the Release phase where we deploy and hand over the code.
Every phase includes weekly demos, Slack communication, and a dedicated project manager. You see progress every week. No black boxes.
What ships with your B2B web app
Every project includes these deliverables by default. No hidden costs.
We ship production-ready code with full documentation. You get the source code in your own GitHub repository from day one.
We also set up CI/CD pipelines, error tracking, and cloud infrastructure. Your team can take over immediately after launch.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Cloud deployment on AWS or GCP
- Automated test suite (unit + integration)
- API documentation (Swagger/OpenAPI)
- Admin dashboard for managing users and data
- Role-based access control (RBAC)
