Expert B2B SaaS Website Development Results by the Numbers

The Difference Between Generic Development and Expert B2B SaaS Website Development
Not every agency knows SaaS. Here's why IRPR delivers sites that actually grow your business.
Generic dev shops treat your site like a brochure. They use WordPress or simple templates and ignore SEO, conversion optimization, and integrations. You end up with a site that looks nice but doesn't drive sign-ups.
IRPR builds B2B SaaS websites as growth engines. Every page is designed for the buyer's journey, integrated with your tools, and built for search engines. We test everything.
- No experience selling SaaS
- Uses WordPress or basic static HTML
- No integration knowledge
- Slow iterations (4+ months)
- No A/B testing or conversion tracking
- You don't own the code
- Built 200+ B2B SaaS websites
- Next.js, React, headless CMS
- Integrated Stripe, HubSpot, Salesforce
- 8-12 week delivery
- Built-in A/B testing with VWO
- 100% code ownership
How We Build Your Expert B2B SaaS Website in 4 Phases
Our process is designed to move fast without sacrificing quality.
We start with a 2-week discovery phase to map your buyer personas, conversion goals, and tech stack. You get a detailed roadmap with a fixed price before any development begins.
From there we design, build, and launch your site. Each phase ends with a review so you stay in control. No surprises, no scope creep.
What Ships With Every Expert B2B SaaS Website
Every project includes these deliverables by default. No hidden fees.
You get full ownership of the source code, documentation, and deployment pipeline. We don't lock you in to proprietary systems.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions or AWS CodePipeline
- Headless CMS setup (Sanity or Contentful)
- Stripe integration for payments and pricing pages
- HubSpot or Salesforce form integration
- Google Analytics 4 and Mixpanel event tracking
- SEO meta tags, sitemap, structured data (Schema.org)
- Sentry error tracking and uptime monitoring
- Responsive design for mobile and tablet
