We ship production-ready SaaS platforms in 12 weeks. No hourly billing, no scope creep.
IRPR is a B2B SaaS development firm that builds multi-tenant platforms, API-first backends, and white-label solutions. We use Next.js, React, Node.js, Python, PostgreSQL, AWS, and Kubernetes to produce production-grade software.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance - SOC 2 Type II, HIPAA, PCI-DSS, FERPA - so your SaaS can sell to regulated industries from day one.

Why IRPR Is the Best B2B SaaS Development Firm
Over 200 products delivered across 50 countries with a 98% on-time delivery rate.
We start with a 2-week Roadmap phase where we define the full architecture, data model, and API contracts. You get a fixed price before any code is written. No surprises.
Our senior engineers work in overlapping time zones (US East Coast to Central Europe) so your team gets 10+ hours of daily collaboration. Every project uses GitHub, Linear, Sentry, and a CI/CD pipeline on GitHub Actions.
Generic Dev Shops vs. a Dedicated B2B SaaS Development Firm
Most agencies reuse templates and run on hourly billing. We build custom, multi-tenant SaaS from day one.
Generic shops treat every project like a brochure website. They don't understand tenant isolation, usage metering, or SOC 2 compliance. Their developers rotate every 3 months because the work is boring.
IRPR only builds B2B SaaS. Our engineers have shipped billing engines, analytics platforms, and compliance middleware for companies in healthcare, fintech, and logistics. We don't rotate developers mid-project.
- Hourly billing with no cap
- Single-tenant architecture (hard to scale)
- No compliance readiness (HIPAA, SOC 2)
- Junior developers on your project
- No API documentation or webhooks
- 6-12 month delivery on MVPs
- Fixed price from Roadmap phase (week 2)
- Multi-tenant SaaS with tenant-level encryption
- Built-in compliance (HIPAA, SOC 2, PCI-DSS, FERPA)
- Senior engineers with 10+ years experience
- OpenAPI docs, webhooks, and event-driven architecture
- Production-ready MVP in 8-12 weeks
Our B2B SaaS Development Process
From idea to release in four predictable phases. No scope creep, no surprises.
We follow a proven framework: Idea, Roadmap, Product, Release. Every phase ends with a handover document so you know exactly what ships and when.
The Roadmap phase costs a fixed $8,500 and includes a full technical blueprint. If you proceed, that cost is deducted from your total project price. If not, you own the blueprint.
What Ships With Every B2B SaaS Platform
You get more than code. You get a production-ready system with monitoring, CI/CD, and compliance tools.
Every B2B SaaS project includes a deployment pipeline, error tracking, and a billing integration. We don't leave you with a pile of code and no support.
All deliverables are in your repo from day one. You can deploy to AWS, GCP, or Azure with a single command.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions (tests, builds, deploys)
- Docker containers and Docker Compose for local development
- Terraform infrastructure-as-code for AWS (or your cloud)
- Sentry error and performance monitoring
- Stripe integration for subscriptions and invoicing
- PostgreSQL database with automated backups
- HTTPS with auto-renewing SSL certificates (Let's Encrypt)
- API documentation via Swagger/OpenAPI
- Admin dashboard for managing users, plans, and usage

Why teams hire us.
Fixed Price, Not Hourly
Every B2B SaaS project has a fixed price determined during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. 98% of our projects finish within budget.
Built for Regulated Industries
We ship B2B SaaS platforms that are SOC 2 Type II, HIPAA, PCI-DSS, and FERPA ready. Our architecture includes audit logs, encryption at rest, and access controls from day one.
Senior Engineers Only
Every engineer on your project has 10+ years of experience. No juniors, no offshore interns. Our team has built SaaS platforms for Airbnb, Zendesk, and Stripe alumni.
Full Code Ownership
You own the source code from the first commit. We never use code templates that we license. You can deploy, modify, or resell the software without restrictions.
8-12 Week MVPs, Not 8 Months
Our average MVP delivery is 12 weeks. We achieve this by scoping tightly, using proven patterns (multi-tenancy, event sourcing, microservices), and avoiding scope creep.
Production Support After Launch
We offer a 30-day warranty on all delivered software. After that, you can buy a monthly support retainer (starting at $4,500/mo) for maintenance, bug fixes, and minor features.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
