Why Expert B2B Web App Development Developers Matter
Building a B2B web app is different from a consumer app. You need security, multi-tenancy, and integrations from day one.
B2B web apps handle sensitive data and complex business logic. A generic developer might miss compliance requirements or build something that doesn't scale past 100 users. IRPR has shipped over 200 B2B products, with an average uptime of 99.9% on AWS infrastructure.
Our team of senior engineers uses TypeScript, Python, and Go to build stateless, horizontally scalable backends. We set up CI/CD pipelines in week 1 and deploy to staging by week 3. Every project includes automated testing with Jest and Cypress.
Expert B2B Web App Development Developers vs Generic Shops
Not all developers can handle B2B complexity. Here is what sets IRPR apart.
Generic development shops treat every project the same. They use hourly billing, miss compliance deadlines, and deliver code that needs a rewrite. IRPR is different. We start with a fixed-price Roadmap phase that defines the entire scope.
We assign a dedicated team of senior engineers who have built B2B apps for fintech, healthcare, and logistics. You get a product manager, a tech lead, and QA engineers. No junior developers, no offshore handoffs.
- Hourly billing with no cap
- No compliance expertise
- Junior developers on your project
- No CI/CD setup included
- Code ownership unclear
- 6-month delivery timelines
- Fixed price from Roadmap phase
- HIPAA, PCI-DSS, SOC 2 ready
- Senior engineers only (7+ years experience)
- CI/CD pipeline in week 1
- Full code ownership transferred
- 12-week MVP delivery
How We Build Your B2B Web App
Our process is designed for speed and clarity. You know exactly what ships and when.
We follow a four-phase framework: Idea, Roadmap, Product, Release. The Roadmap phase takes 2 weeks and produces a detailed spec with wireframes, tech stack decisions, and a fixed price. No surprises.
The Product phase runs 8 to 12 weeks. We build in 2-week sprints with a demo at the end of each sprint. You see working software every 14 days and can adjust priorities as you go.
What Ships with Every B2B Web App
You get a production-ready system, not just code. Everything below is included in the fixed price.
We deliver more than a working app. Every project includes infrastructure, monitoring, and documentation. Your team can take over immediately or we can continue with a maintenance retainer.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Docker containers deployed on AWS ECS or GCP Cloud Run
- PostgreSQL or MongoDB database with automated backups
- Sentry error tracking and Datadog monitoring
- Stripe or Braintree payment integration (if needed)
- Swagger/OpenAPI documentation for all endpoints
- Admin dashboard with user management and analytics
- Automated test suite (unit, integration, e2e)
- Security audit report (OWASP top 10)
