Why B2B Web Development Matters for Your Business
B2B web apps need reliability and speed to handle complex workflows and high transaction volumes.
Your buyers expect 24/7 access to portals, dashboards, and integrations. A web app built with React and Node.js can process 1,000 requests per second while keeping latency under 200 ms.
IRPR ships every app with monitoring, CI/CD, and auto-scaling. Our apps maintain 99.9% uptime and pass SOC 2 audits within the first quarter.
How IRPR Delivers Better B2B Web Development
Most agencies deliver incomplete specs and surprise bills. IRPR works differently.
We start with a two-week Roadmap phase where we define the architecture, tech stack, and fixed price. No guesswork. No hidden fees.
Your code is hosted in your own GitHub repo from day one. You own everything we build. We also set up automated deployments so you can release updates immediately.
- Vague project specs
- Hourly billing with no cap
- No compliance support
- Code stays on their servers
- Slow migration to production
- No monitoring or alerts
- Fixed price after Roadmap
- SOC 2, HIPAA, PCI-DSS ready
- Full source code ownership
- CI/CD on GitHub Actions
- 12-week delivery guarantee
- Post-launch support included
Our Process for Building B2B Web Apps
We follow a four-phase process that turns your idea into a production-ready web application.
Each phase has clear deliverables and a fixed timeline. You see progress every two weeks through sprint demos.
By the end of week 12, you have a deployed app with monitoring, backups, and documentation.
What Ships With Every B2B Web App
Your B2B web application comes fully equipped for production use from day one.
We don't cut corners. Every app includes monitoring, CI/CD, and compliance tooling. You don't need to hire another agency for deployment or security.
Your team can start using the app immediately. We also provide 4 weeks of post-launch support for bug fixes and user feedback.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- AWS infrastructure (EC2, RDS, S3, CloudFront)
- Sentry error tracking and alerts
- PostHog product analytics
- Datadog performance monitoring
- Stripe billing integration (if needed)
- Auth0 authentication with SSO
- Figma design files and component library
- Loops automated email integration
What we ship in this practice.
Multi-Tenant SaaS Platform
A B2B HR tech startup needed a platform for managing employee benefits across companies. IRPR built the app with Next.js, PostgreSQL, and Stripe. The platform launched in 10 weeks and handles 5,000 users with 99.9% uptime.
Enterprise Partner Portal
A manufacturing firm wanted a portal for 300 resellers to manage orders, inventory, and support tickets. IRPR built a white-label solution using React, Node.js, and Salesforce integration. Reseller ticket volume dropped by 40% in the first month.
B2B Parts Marketplace
An industrial supply company needed a multi-vendor marketplace for equipment parts. IRPR built the platform with Next.js, Elasticsearch, and Stripe Connect. Vendors added 500+ new products within three months of launch.
Customer Self-Service Portal
A fintech company wanted a customer portal for account management and transaction history. IRPR built a responsive app with React, Node.js, and Plaid integration. Self-service usage grew to 80% of all customer interactions.
Internal Admin Dashboard
A logistics company needed a real-time dashboard to track shipments, driver routes, and fuel costs. IRPR built the app with React Admin, PostgreSQL, and Mapbox. Managers saved 20 hours per week on manual reporting.
API Backend for B2B Integrations
A real estate data provider needed a REST API to sell property data to other businesses. IRPR built an API with Node.js, PostgreSQL, and Redis caching. The API processes 10 million requests per month with under 100 ms latency.
Why teams hire us.
Fixed Price, Not Hourly
Every B2B web project gets a fixed quote at the end of the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior Engineers Only
IRPR only hires engineers with 7+ years of experience. Every project is staffed with a lead engineer who has shipped at least 5 production web applications.
12-Week Delivery
We ship production-ready B2B web apps in 8-12 weeks. Our 12-week average across 200+ projects beats industry averages by 6 weeks.
Full Code Ownership
You own all source code from day one. We host it in your GitHub repo and transfer all assets upon payment. No lock-in, no recurring fees.
Compliance Built In
We build B2B web apps that meet SOC 2, HIPAA, and PCI-DSS standards from the start. No expensive retrofits after launch.
No Contract Lock-In
Our engagement is milestone-based. You can pause or stop after any phase. We want you to stay because you see results, not because of a contract.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
