Why IRPR delivers expert B2B SaaS website development
Our process combines senior engineers, fixed pricing, and compliance readiness to ship fast.
Every B2B SaaS website IRPR builds starts with a Discovery phase where we map your user journeys and conversion goals. We then produce a fixed-price Roadmap in week 2 so there are no surprises.
Our senior engineers use Next.js and headless CMS to build sites that load in under 2 seconds and score 95+ on Lighthouse. We include CI/CD pipelines and 99.9% uptime SLA on Vercel.
How IRPR differs from generic web development shops
Most agencies lack compliance knowledge and use hourly billing. IRPR is built for B2B SaaS.
Generic dev shops treat your SaaS website like a brochure site. They do not know SOC 2 or PCI-DSS requirements and often deliver late with cost overruns.
IRPR builds every site with compliance built-in from the start. We use a fixed-price model based on a detailed Roadmap so you know the exact timeline and cost by week 2.
- No compliance knowledge
- Hourly billing leads to overspend
- Unknown timeline (often 6+ months)
- No post-launch support SLA
- Generic WordPress themes
- No conversion optimization
- Built-in SOC 2/HIPAA compliance
- Fixed price from $80K
- 12-week delivery guarantee
- 12-month support included
- Next.js + headless CMS
- Conversion-optimized design
Our process for expert B2B SaaS website development
We break the project into four phases to ensure speed and transparency.
Every engagement starts with a Discovery call where we understand your buyers and compliance needs. Then we create a Roadmap with wireframes and a fixed price.
The Build phase uses senior engineers who work in two-week sprints. You see a live staging environment by week 6. Launch happens in week 12 with a full performance audit.
