Expert B2B SaaS Development ServicesDevelopment Services
We build B2B SaaS platforms that handle complex billing and multi-tenant data. Your MVP ships in 8-12 weeks with a fixed price.
IRPR builds B2B SaaS platforms for companies that need multi-tenant architecture, usage-based billing, and role-based access control. We use Next.js, Node.js, PostgreSQL, Stripe, and AWS to ship production-grade software.
Every project starts with a Roadmap phase (week 2) where we define scope and price. MVPs ship in 8-12 weeks. Fixed pricing ranges from $80K to $250K. We comply with SOC 2, HIPAA, and PCI-DSS standards.
We work with B2B founders who need a technical co-founder, product managers at mid-market companies migrating from legacy systems, enterprise teams launching internal tools, and VC-backed startups building their first SaaS product.

Why B2B SaaS Development Needs Expert Engineers
B2B SaaS platforms handle complex billing, multiple tenants, and strict compliance requirements.
A generic web developer cannot build a multi-tenant SaaS with proper data isolation. Each client needs their own schema or row-level security. IRPR uses PostgreSQL row-level security and AWS RDS to keep tenant data separate. We also set up Stripe Billing for usage-based pricing and subscription management.
Expert B2B SaaS development services from IRPR include SOC 2 readiness from day one. We configure logging, access controls, and audit trails to pass your first compliance audit. Our team has shipped over 200 SaaS products for clients in 50 countries.
What Makes IRPR Different for B2B SaaS
Most development shops bill hourly and let scope creep eat your budget. IRPR does not.
We give you a fixed price after the Roadmap phase (week 2). No hourly billing, no surprise invoices. You know the cost before we write a line of production code.
Our team includes senior engineers only. No junior developers learning on your dime. Every engineer has built at least 5 SaaS products before joining IRPR. That experience shows in code quality and delivery speed.
- Hourly billing with no cap
- Junior developers assigned to your project
- No SOC 2 or HIPAA experience
- Scope creep leads to budget overruns
- No dedicated QA engineer
- Code ownership unclear
- Fixed price after Roadmap phase
- Senior engineers only (5+ SaaS products each)
- SOC 2 and HIPAA compliant by design
- Scope locked in Roadmap phase (week 2)
- Dedicated QA engineer on every project
- Full code ownership transferred to you
How We Deliver Expert B2B SaaS Development Services
