Why choose a professional B2B SaaS website development company
Your website is your sales engine. It must load fast, convert visitors, and scale with your product.
A generic agency builds a brochure site that looks nice but fails on SEO and conversion. IRPR builds sites that rank on Google, load in under 2 seconds, and integrate with your CRM and billing system. We use Next.js for static generation, Tailwind for consistent design, and Sanity for content management.
Our sites include built-in A/B testing with Split.io, real-time analytics with PostHog, and automated deploys via GitHub Actions. We also set up Sentry error tracking and Datadog monitoring. Every site passes Google Lighthouse scores above 90 for performance and accessibility.
How IRPR differs from other web development agencies
Most agencies bill by the hour and deliver late. IRPR charges a fixed price and ships on time.
Generic dev shops start coding without a clear roadmap. They use hourly billing, so scope creep is profitable for them. They often outsource to junior developers and deliver a site that breaks on mobile.
IRPR starts with a 2-week Roadmap phase where we define every page, component, and integration. We give you a fixed price for the full build. Our team consists of senior engineers only (8+ years experience). We ship the site in 8-12 weeks with full documentation.
- Hourly billing with no cap
- Scope creep is profitable for them
- Junior developers or offshore teams
- No roadmap or fixed timeline
- Site breaks on mobile or slow load
- You don't own the code
- Fixed price from the start
- Scope defined in Roadmap phase
- Senior engineers only (8+ years)
- 8-12 week timeline, on time 98%
- Lighthouse scores above 90
- You own the full codebase
Our process for building your B2B SaaS website
We follow a repeatable 4-phase process that de-risks your project and delivers on time.
Phase 1 is the Roadmap. We audit your product, interview your stakeholders, and produce a detailed spec with wireframes, tech stack, and a fixed price. This takes 2 weeks and costs $5K (credited to the build).
Phase 2 is Design. We create high-fidelity mockups in Figma for every page and screen. You review and approve before any code is written. Phase 3 is Build: we develop the site in sprints with daily updates. Phase 4 is Release: we deploy to production, set up monitoring, and hand over the keys.
What ships with your B2B SaaS website
Every project includes a complete production-ready system, not just a design.
You get source code in your own GitHub repository, a CI/CD pipeline on GitHub Actions, and automated deployments to Vercel. We also set up Sentry for error tracking, PostHog for analytics, and Split.io for A/B testing.
We include a style guide in Storybook, a content management system (Sanity or Strapi), and SEO metadata for every page. You also get a 30-minute walkthrough video and a written handover document.
