Why hire senior B2B SaaS website development consultants
IRPR's consultants bring 10+ years of SaaS experience to every project, not junior devs learning on your dime.
Our team has shipped 200+ SaaS products across 50 countries. We use React, Next.js, Node.js, and PostgreSQL on AWS or Vercel. Every project includes CI/CD, error monitoring with Sentry, and uptime monitoring with Datadog.
We charge a fixed price based on the Roadmap phase. No hourly billing. No scope creep. You know the cost before we write a single line of code. Average project runs 8-12 weeks from kickoff to launch.
Generic dev shop vs senior B2B SaaS website development consultants
Most agencies assign junior developers and bill by the hour. IRPR assigns senior engineers and charges a fixed price.
Generic dev shops often pitch a low hourly rate but inflate hours. They use junior talent and miss SaaS-specific needs like authentication, billing, and multi-tenancy. You end up paying more for a slower, buggier product.
IRPR assigns senior engineers who have built SaaS platforms from scratch. We scope the entire project in the Roadmap phase, fix the price, and deliver in 8-12 weeks. No surprises, no excuses.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No SaaS-specific architecture
- No CI/CD or monitoring setup
- Code ownership often unclear
- Average delivery 6+ months
- Senior engineers with 10+ years SaaS experience
- Fixed price from Roadmap phase (week 2)
- Built-in authentication, billing, multi-tenancy
- CI/CD on GitHub Actions + Sentry + Datadog
- Full code ownership in your repo
- Delivery in 8-12 weeks
How our senior B2B SaaS website development consultants work
We follow a 4-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed timeline.
Phase 1 (Idea): We align on your vision, target users, and core features. This takes 1 week and costs nothing if you choose to proceed.
Phase 2 (Roadmap): We produce a detailed technical specification with wireframes, architecture diagrams, and a fixed price quote. This takes 1-2 weeks and costs $5K-$10K, credited toward the build.
