Premium B2B SaaS Website Development CompanyPremium B2B SaaS
Your SaaS platform needs a website that converts enterprise buyers. We build it in 8-12 weeks with a fixed price and full code ownership.
IRPR builds premium B2B SaaS websites using Next.js, React, Vue, Node.js, Python, and AWS. Our architecture supports SSO (SAML, OAuth), RBAC, multi-tenancy, and real-time data sync via WebSockets or GraphQL subscriptions. Every site is optimized for page-speed (>90 Lighthouse) and meets WCAG 2.1 AA accessibility standards.
Your first phase (Roadmap) takes 1 week and costs $5K. The full build runs 8-12 weeks with a fixed price typically between $80K and $250K. You get HIPAA, PCI-DSS, or SOC 2 compliance baked in from day one, not bolted on later. We ship code to your repo, a CI/CD pipeline, and 99.9% uptime SLA.
We work with B2B SaaS founders who need a scalable marketing site and app portal, engineering VPs upgrading legacy .NET or Java monoliths to a modern stack, and product leaders at Series A/B startups who want a premium design system and developer-friendly CMS (Contentful, Strapi, or Sanity).

Premium B2B SaaS website development by the numbers
IRPR has shipped over 200 SaaS products to clients in 50+ countries. Here is what that experience delivers for your project.
Our development team averages 12 years of experience per engineer. We use React, Next.js, Node, Python, and TypeScript on every project. Every site we build includes automated Lighthouse audits, Cypress E2E tests, and a Sentry error tracking integration.
We serve B2B SaaS companies from seed stage to Series C. Recent clients include a $50M ARR fintech platform and a HIPAA-compliant telemedicine provider with 10,000 daily users. Every project ships with a full design system in Figma and a Storybook component library.
How IRPR is different from generic dev shops
Most agencies build a B2B SaaS website once and hand it over. IRPR builds it to scale, with compliance and CI/CD included. Here is the comparison.
Generic shops often start with a template and customize colors. They skip error tracking, monitoring, and automated testing. You end up with a site that breaks on every Chrome update and has no audit trail for SOC 2 or HIPAA.
IRPR writes every line of code from scratch for your specific SaaS. We set up AWS infrastructure with CloudFormation, a CI/CD pipeline in GitHub Actions, and a monitoring stack (Datadog + Sentry). Compliance is verified in the Roadmap phase, not after launch.
- Starts with a WordPress or Webflow template
- No automated testing or CI/CD
- No compliance documentation
- Hourly billing with scope creep
- Unknown code ownership after project
- No post-launch monitoring
- Custom-built with Next.js, React, or Vue
- CI/CD pipeline via GitHub Actions
- HIPAA, SOC 2, PCI-DSS from day one
- Fixed price in Roadmap phase (week 2)
- Full code ownership in your repo
- Sentry + Datadog monitoring included
Our 4-phase process for B2B SaaS website development
We follow a repeatable 4-phase process: Idea, Roadmap, Product, Release. Each phase has a fixed scope and deliverable.
Phase one (Idea) takes 1-2 days. We align on your business goals, target ICP, and core features. You share your existing brand guidelines, APIs, and compliance requirements. We give you a project brief in return.
Phase two (Roadmap) is a 1-week deep dive. Our team audits your current stack, maps user flows, chooses the tech stack (e.g. Next.js + Prisma + PostgreSQL), and writes a fixed-price proposal. No surprises. You pay $5K for this phase, and it is credited toward the build.
What ships with every premium B2B SaaS website
Every project from IRPR includes these deliverables. No upselling, no hidden costs.
We believe in shipping a complete product, not a minimum viable prototype. Here is exactly what you receive at the end of the 8-12 week build.
- Figma design system with component library (50+ components)
- Next.js or React frontend with TypeScript
- Node.js API (Express or NestJS) with PostgreSQL database
- Stripe Billing integration with metered pricing support
- Auth0 or Firebase Auth with SAML/SSO for enterprise customers
- CI/CD pipeline on GitHub Actions with automated E2E tests
- Infrastructure as code (AWS CloudFormation or Terraform)
- Sentry error tracking + Datadog performance monitoring
- HTTPS, CSP headers, and OWASP Top 10 security checklist
- Admin dashboard with user management, logs, and billing tools

Senior engineers only, no juniors
Every IRPR engineer has 10+ years of production experience. You talk directly to the person writing your code. No project managers, no account managers.
