Why experienced B2B SaaS website development services matter
Your website is the first thing prospects see. A slow or confusing site loses deals.
IRPR has shipped 200+ websites for B2B SaaS companies. We use Next.js for server-side rendering which gives you fast load times and good SEO. Our sites score 90+ on Lighthouse performance audits out of the box.
We add analytics early. PostHog tracks user behavior on your pricing page and signup flows. This data helps you optimize conversion rates within weeks of launch.
The difference between IRPR and a generic dev shop
Most agencies build a static site and walk away. IRPR builds a platform your team can own.
A generic dev shop gives you a WordPress site with page builders. You get slow load times, security holes, and no support for Stripe subscriptions.
IRPR builds with Next.js and a headless CMS. You get source code in your repo, CI/CD pipelines, Sentry error tracking, and a team that answers questions for 30 days after launch.
- WordPress with page builder
- no CI/CD pipeline
- no error monitoring setup
- no post-launch support
- hourly billing with scope creep
- no compliance documentation
- Next.js with server-side rendering
- CI/CD via GitHub Actions + Vercel
- Sentry error tracking from day one
- 30 days hands-on post-launch
- fixed price from Roadmap phase
- SOC 2 and GDPR compliance ready
How we build your B2B SaaS website in 12 weeks
Our process is documented and repeatable. You know what ships each week.
We start with a 2-week Roadmap phase. You get a detailed spec, wireframes, and a fixed price. No surprises.
Then we build in 6-week sprints. Your team reviews live demos every Thursday. We deploy a beta in week 10, then launch in week 12.
What ships with every B2B SaaS website
No half-baked deliverables. Every project includes these by default.
You get more than a design file. You get a production system that handles traffic spikes, subscription cancellations, and content updates.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Vercel production deployment
- Stripe subscription integration
- Sentry error tracking
- PostHog analytics setup
- Headless CMS (Sanity or Strapi)
- SEO meta tags and Open Graph
- Lighthouse score 90+
- 30 days post-launch support
