Why choose a senior B2B SaaS development firm
Building B2B SaaS is different from building a consumer app. You need senior engineers who understand multi-tenancy, billing, and compliance.
IRPR has shipped 200+ B2B SaaS products. Each one uses a modern stack: Next.js or React for the frontend, Node.js or Python for the backend, and PostgreSQL or MongoDB for data. Every product includes Stripe billing, Sentry error monitoring, and a CI/CD pipeline on GitHub Actions.
Our average MVP timeline is 12 weeks. For that, you get a working product with user management, subscription plans, and a production deployment on AWS or GCP. We handle the infrastructure so you can focus on sales.
Generic dev shops vs a senior B2B SaaS development firm
Not all development firms are equal. Here is the difference between a generic shop and IRPR.
Generic dev shops assign junior developers, use hourly billing, and ship code that does not scale. They lack experience with multi-tenancy, subscription billing, and compliance.
IRPR assigns senior engineers only. Every project has a fixed price, a clear timeline, and a dedicated lead. We ship production-ready code with CI/CD, monitoring, and documentation.
- Junior developers with 2-3 years experience
- Hourly billing with no cap
- No multi-tenant architecture experience
- No compliance knowledge (SOC 2, HIPAA)
- No CI/CD or monitoring setup
- Code ownership unclear
- Senior engineers with 10+ years experience
- Fixed price from the Roadmap phase
- Built 200+ multi-tenant SaaS platforms
- SOC 2, HIPAA, PCI-DSS compliant by default
- CI/CD on GitHub Actions, Sentry monitoring included
- Full source code ownership
How we build your B2B SaaS in 12 weeks
Our process is structured to de-risk your investment. You know the price and timeline before we write a line of code.
Week 1 is the Idea phase. We map out your product vision, define the target users, and identify the core value proposition. You get a product brief.
Week 2 is the Roadmap phase. We define the tech stack, database schema, API design, and a fixed price. You approve and we start building.
