Why B2B SaaS Development Matters
A single-tenant app costs 3x more to maintain than a multi-tenant SaaS platform. Here is why B2B companies switch.
B2B buyers expect software that scales with their headcount, integrates with their existing stack, and meets compliance requirements. A custom B2B SaaS platform built on a multi-tenant architecture reduces infrastructure costs by 60% compared to running separate instances per client. IRPR has shipped 200+ such platforms across 50 countries.
The average B2B SaaS platform we build handles 50,000+ monthly active users, processes $2M+ in subscription revenue annually, and maintains 99.9% uptime. We use Next.js for the frontend, Node.js for the API layer, PostgreSQL for data, and deploy on AWS with auto-scaling.
Generic Dev Shop vs IRPR
Most agencies promise a B2B SaaS platform but deliver a prototype that cannot scale. Here is the real difference.
A generic dev shop builds one tenant at a time. They hardcode customer configurations, skip automated testing, and hand you a codebase that breaks when you add a second client. IRPR builds multi-tenant from day one.
We use feature flags, database-per-tenant or row-level security, and CI/CD pipelines that deploy to separate environments per customer. Every platform includes usage analytics, automated billing, and a customer portal.
- Builds single-tenant first, then tries to retrofit multi-tenancy
- No automated billing integration
- No RBAC or permission model
- No CI/CD pipeline
- No monitoring or error tracking
- Delivers in 6+ months with cost overruns
- Multi-tenant architecture from week 1
- Stripe billing with usage-based pricing
- Role-based access control built in
- CI/CD on GitHub Actions with Sentry monitoring
- 99.9% uptime with auto-scaling
- Delivers in 8-12 weeks at fixed price
Our B2B SaaS Development Process
We ship a production-ready B2B SaaS platform in 12 weeks. Here is how we get there.
Every project starts with a 2-week Roadmap phase where we define the data model, API contracts, and billing logic. You get a fixed price quote before any code is written.
The build phase runs in 2-week sprints. You see a working demo after sprint 1. We deploy to staging in sprint 3. Production launch happens in sprint 6.
What Ships With Every B2B SaaS Platform
Every platform ships with these deliverables. No hidden extras.
You get the full source code, infrastructure-as-code, and documentation. We do not use proprietary frameworks or lock you into a platform.
All code is in your GitHub repo from day one. You can deploy anywhere at any time.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and performance monitoring
- Stripe billing integration with subscription plans
- Multi-tenant database schema with row-level security
- Admin dashboard with user management and billing overview
- Customer portal for self-service account management
- API documentation via Swagger/OpenAPI
- Load test results with 10,000 concurrent users
- 30 days of post-launch support

Senior engineers only
We do not hire juniors or offshore teams. Every engineer has 8+ years of experience and has shipped at least 5 production SaaS platforms. Your project gets a lead architect who stays through launch.
Multi-tenant from day one
We build with row-level security or database-per-tenant from the first sprint. No retrofitting. Your platform scales to 1,000+ tenants without a rewrite.
Compliance built in
We design for SOC 2, HIPAA, or PCI-DSS from the start. Our platforms include audit logs, encryption at rest and in transit, and role-based access controls. No afterthought compliance.
