B2B SaaS Website Development Metrics That Matter
Data from 200+ projects shows what makes a SaaS website convert.
A slow website kills signups. Google research shows a 1-second delay cuts mobile conversions by 20%. We build on Next.js with automatic image optimization, code splitting, and CDN caching. Every site we ship scores 90+ on Lighthouse Performance and passes Core Web Vitals.
Our sites average 3.2% conversion rate for free trial signups and 1.8% for demo requests. We use Hotjar heatmaps and FullStory session recordings to identify friction points. Then we run A/B tests with VWO to improve each page by 10-15% per quarter.
Generic Web Agency vs IRPR B2B SaaS Website Development
Not all agencies build SaaS websites that convert. Here is the difference.
Generic agencies build brochure sites. They use WordPress or Wix, add a contact form, and call it done. They do not understand subscription billing, pricing tiers, or user onboarding. Their sites load in 4 seconds and convert at 0.5%.
IRPR builds SaaS websites that work as growth engines. We integrate Stripe for payments, Auth0 for authentication, and Segment for analytics. We optimize every page for search with Next.js SSR and structured data. Your site loads in under 1 second and converts at 3%+.

Our B2B SaaS Website Development Process
From idea to live site in 8-12 weeks with a fixed price.
We follow a four-phase process: Idea, Roadmap, Product, Release. In the Roadmap phase (week 2), we define every page, user flow, and integration. You get a fixed price and timeline before any code is written. No surprises.
In the Product phase (weeks 3-10), we build and iterate in 2-week sprints. You see progress every Friday with a demo. In the Release phase (weeks 11-12), we deploy to production, set up monitoring, and train your team.
