Leading Custom SaaS Development VendorSaaS Development Vendor
We build production-grade SaaS platforms from scratch. 200+ products shipped to 50+ countries.
IRPR builds custom SaaS platforms that scale. We use Next.js, React, Node.js, Python, PostgreSQL, and AWS to deliver multi-tenant systems with subscription billing, RBAC, and API-first architectures.
Every project ships in 8-12 weeks at a fixed price between $80K and $250K. Our platforms are SOC 2, HIPAA, and PCI DSS compliant by default, with automated CI/CD and error monitoring.
Founding CTOs hire us to build their first product. Enterprise IT leaders use us to migrate legacy systems. SaaS founders come to us when they need to scale from MVP to Series A. Product managers trust us for rapid prototyping without hourly billing.

Proven results as a leading custom SaaS development vendor
Our track record shows the numbers that matter to buyers.
IRPR has delivered over 200 SaaS products across 50+ countries. Our teams maintain a 98% on-time delivery rate and 99.9% average uptime for deployed platforms.
Every platform goes through SOC 2 Type II audits, static code analysis, and load testing. We ship production-ready code that passes security reviews on day one.
The difference between generic agencies and IRPR
Not all development vendors deliver the same quality.
Generic agencies often start coding without a clear roadmap, then charge by the hour when scope creeps. IRPR uses a fixed-price Roadmap phase in week 2 that locks scope, timeline, and cost before any code is written.
We also enforce compliance from day one. Every project starts with SOC 2 controls, GDPR data handling, and automated infrastructure via Terraform. You get a production-ready system, not a prototype.
- Vague requirements document
- Hourly billing with no cap
- No compliance framework
- Junior developers on the team
- Source code may be licensed
- Slow, manual deployments
- Detailed Roadmap with wireframes and estimates
- Fixed price from start
- SOC 2, HIPAA, PCI DSS built-in
- Senior engineers with 8+ years experience
- Full source code ownership
- CI/CD pipeline with GitHub Actions and Sentry
How we build your custom SaaS platform
Our process from idea to release is four discrete phases, each with a clear deliverable.
Phase 1 (Idea) is a 1-week sprint where we align on goals, user personas, and technical constraints. You get a product brief with prioritized features.
Phase 2 (Roadmap) delivers a fixed-price quote, wireframes, and an 8-12 week timeline. No code is written until you approve the plan.
What ships with every custom SaaS platform
You get more than code. Every project includes a full operational toolkit.
Our delivery package covers everything needed to run a live SaaS service. From infrastructure scripts to error tracking, we include tools that usually take months to set up.
All code is in your GitHub repository from day one. There are no licensing fees and no hidden subscriptions.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and automated tests
- Sentry error tracking and performance monitoring
- Terraform scripts for repeatable AWS infrastructure
- Healthcheck endpoints and Datadog dashboards
- Postman collections and API documentation
- Admin panel with user management and audit log
- Load testing report with k6 or Artillery
- SOC 2 evidence pack (policies, backups, encryption)
