Why hire top B2B web app development consultants
Building a B2B web app is different from a consumer app. You need multi-tenant architecture, role-based access, and integrations with enterprise tools.
Generic dev shops often lack experience with complex B2B requirements like SSO, audit logs, and data isolation. IRPR has built over 200 products for B2B companies across 50 countries. We know what works and what breaks.
We use a fixed price model so you know the cost upfront. Our average MVP ships in 12 weeks. We handle compliance from day one, not as an afterthought.
How IRPR differs from other B2B web app development consultants
Most agencies bill by the hour and change scope mid-project. IRPR does the opposite.
We start with a two-week Roadmap phase where we define every feature, integration, and compliance requirement. You get a fixed price quote before any development begins. No surprises.
Our engineers are senior only. We do not outsource or use junior developers. Every project has a dedicated tech lead who writes code and reviews pull requests.
- Hourly billing with no cap
- Junior developers with minimal oversight
- Scope creep without change orders
- No compliance expertise
- Code ownership often unclear
- Handoff with minimal documentation
- Fixed price locked after Roadmap
- Senior engineers only, average 10+ years experience
- Scope defined in writing before build
- SOC 2, HIPAA, PCI-DSS built in
- You own all source code and IP
- Full documentation and CI/CD pipeline included
Our process for building B2B web apps
We follow a four-phase process that turns your idea into a production-ready web app in 12 weeks.
Every project starts with a discovery call where we review your requirements, tech stack preferences, and compliance needs. We then move into the Roadmap phase.
The build phase uses two-week sprints with demos at the end of each sprint. You see progress every 14 days and can adjust priorities as needed.
What ships with your B2B web app
We do not just hand over code. You get a fully operational system with everything you need to run and scale.
All source code goes into your private GitHub or GitLab repository from day one. You own every line of code and all intellectual property. There is no licensing fee or ongoing royalty.
We also set up your hosting infrastructure on AWS or Azure with auto-scaling, database backups, and a CI/CD pipeline. Your team can deploy changes with a single pull request.
- Source code in your private repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Production deployment on AWS or Azure
- Sentry error tracking and monitoring
- Database backups and disaster recovery plan
- User authentication with Auth0 or Clerk
- API documentation with Swagger
- Admin dashboard for managing users and settings
- Compliance documentation for SOC 2 or HIPAA
- One-year infrastructure support and bug fixes
