Why hire an expert B2B web app development agency
Building a B2B web app requires handling complex data, multiple user roles, and integrations with existing systems.
IRPR has shipped over 200 B2B web apps across 50 countries. Each project follows a fixed-price model with a clear Roadmap phase. You know the cost and timeline before we write a line of production code.
Our senior engineers use Next.js, Node.js, PostgreSQL, and AWS to build scalable B2B platforms. We integrate with Stripe, Salesforce, HubSpot, QuickBooks, and custom APIs. Compliance is built in from the start.
The difference between IRPR and generic dev shops
Not all agencies deliver the same results for B2B web app development.
Generic dev shops often start coding without a clear plan. They charge hourly, scope creeps, and you end up with code you don't own. IRPR works differently.
We start with a 2-week Roadmap phase that defines every feature, integration, and data model. You get a fixed price and a fixed timeline. No surprises.
- Hourly billing with no cap
- No compliance expertise
- Junior developers on your project
- No onboarding or documentation
- Code stays with them
- No post-launch support
- Fixed price from $80K
- HIPAA, PCI-DSS, SOC 2 built in
- Senior engineers only
- Full onboarding and API docs
- Source code is yours
- 99.9% uptime SLA with monitoring
How we build your B2B web app in 12 weeks
Our process is designed to eliminate risk and deliver a production-ready B2B web app fast.
We follow a 4-phase framework: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a go/no-go decision point.
The Roadmap phase (week 2) produces a detailed spec with wireframes, data models, and API contracts. The Product phase (weeks 3-12) builds the app in 2-week sprints with weekly demos.
What ships with your B2B web app
Every project includes everything you need to run and maintain your application.
We don't just hand over code. You get a fully deployed, monitored, and documented system that your team can manage.
All deliverables are included in the fixed price. No hidden costs for deployment, documentation, or training.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Production deployment on AWS or GCP
- Sentry error tracking and monitoring
- API documentation with Swagger/OpenAPI
- Admin dashboard with user management
- Role-based access control (RBAC)
- Stripe or payment integration
- 30-day post-launch bug warranty
