Expert B2B SaaS Website Development TeamDevelopment Team
We build B2B SaaS websites that convert. 8-12 week timelines, fixed pricing, senior engineers only.
IRPR builds B2B SaaS websites for companies that need more than a template. We use Next.js, React, Tailwind CSS, and headless CMS systems like Contentful or Sanity to create fast, scalable marketing sites and customer-facing portals.
Every project ships in 8-12 weeks. Our fixed pricing starts at $80K and goes up to $250K depending on scope. We handle compliance like SOC 2 for SaaS, HIPAA for healthcare, and PCI-DSS for fintech clients.
We work with three buyer types: SaaS founders who need an MVP website and billing flow, CTOs migrating from legacy platforms to a modern Jamstack architecture, and marketing VPs who want a high-converting landing page with A/B testing and analytics.

Why you need an expert B2B SaaS website development team
Your website is your product's front door. A slow or confusing site loses leads and hurts your brand.
Most generic web agencies build brochure sites. They don't understand SaaS pricing models, API integrations, or the need for real-time data. IRPR's team has built 200+ SaaS products across 50 countries. We know how to structure a site that showcases features, handles trial signups, and integrates with Stripe, HubSpot, and Auth0.
We also handle the technical side that matters for B2B: SOC 2 compliance documentation, PCI-DSS for payment pages, and uptime SLAs of 99.9%. Every site we ship includes automated Lighthouse audits, a CDN via Cloudflare, and server-side rendering for SEO performance.
The difference between IRPR and a generic web dev shop
Not all development teams are built for B2B SaaS. Here's how IRPR stands apart.
When you hire a generic agency, you often get junior developers, unclear requirements, and hourly billing that spirals. IRPR gives you a fixed price, a dedicated senior team, and a clear Roadmap phase before any code is written.
We focus on outcomes: higher conversion rates, faster page loads, and seamless integrations with tools like Salesforce, HubSpot, and Intercom. Our sites are built on Next.js with TypeScript, so they are maintainable and scalable for years.
- Hourly billing with no cap
- Junior developers or outsourced teams
- No compliance understanding
- Brochure sites without real integration
- Long timelines (4-6 months)
- No post-launch support
- Fixed price from week 2
- Senior engineers with 10+ years experience
- HIPAA, PCI-DSS, SOC 2 ready
- Full Stripe, Auth0, HubSpot integrations
- 8-12 week MVPs
- 99.9% uptime SLA and ongoing maintenance
Our process: from idea to launch in 8-12 weeks
We follow a structured 4-phase process that de-risks your project and delivers on time.
Every project starts with a Roadmap phase where we define scope, tech stack, and timeline. This takes 2 weeks and costs a fixed fee of $5K. After that, you get a fixed quote for the build.
We then move to Product, where we design and develop in 2-week sprints. You see working software every sprint. Release includes deployment, documentation, and a 30-day warranty.
What ships when we build your B2B SaaS website
Every project includes a standard set of deliverables. No surprises.
You get more than just a website. We deliver full source code, infrastructure, and documentation so your team can take over immediately.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and Vercel
- Sentry error tracking with alerts
- Responsive design (mobile, tablet, desktop)
- Custom analytics dashboard (Mixpanel or segment)
- Stripe integration with test mode and webhooks
- Auth0 authentication (social login, SSO ready)
- SEO metadata and structured data (JSON‑LD)
- Load testing report (1000 concurrent users tested)
- 30-day warranty with 24h response SLA
