Top Custom SaaS Development DevelopersSaas Development
We build custom SaaS platforms that scale. 8-12 week MVPs with senior engineers and fixed pricing.
IRPR is a team of senior engineers that build custom SaaS platforms for startups and enterprises. We use React, Node.js, PostgreSQL, and AWS to ship production-ready apps with full CI/CD pipelines.
Every project starts with a 2-week Roadmap phase for a fixed price of $8K. Full builds run 8-12 weeks and cost $80K-$250K. We handle SOC 2, HIPAA, and PCI compliance so you can sell into regulated markets.
Founders with a validated idea hire us to replace scrappy code with a scalable SaaS. CTOs use us to add features or rebuild legacy platforms. Product managers bring us in for multi-tenant, white-label, and API-first products.

Why Hire Top Custom SaaS Development Developers
Building a custom SaaS from scratch requires senior engineering, not junior teams.
IRPR has shipped 200+ SaaS products over the last 6 years. Every platform is built with a modern tech stack: React, Next.js, Node.js, PostgreSQL, and AWS. We do not outsource or use offshore junior devs.
Our clients get a fully functional SaaS in 8-12 weeks with unit tests, CI/CD, and a private repo. We handle everything from schema design to Stripe integration. The result is a production-ready app you can sell on day one.
The Difference Between a Generic Dev Shop and IRPR
Not all agencies build SaaS the same way. Here is how we stack up.
Generic dev shops often use hourly billing, rotate junior devs every month, and ship code that needs rewrites. They rarely understand multi-tenant databases, Stripe metered billing, or SOC 2 controls.
IRPR assigns senior engineers from day one. We give you a fixed price, weekly demos, and full code ownership. Our team has built SaaS for healthcare, fintech, and logistics that passed external audits on first try.
- Hourly billing with no cap
- Junior or mid-level developers
- No compliance expertise
- Code ownership unclear
- Monthly check-ins only
- No CI/CD pipeline
- Fixed price per phase (Roadmap $8K, Build $80K-$250K)
- Senior engineers only (7+ years experience)
- HIPAA, SOC 2, PCI, FERPA out of the box
- Full code ownership with private GitHub repo
- Weekly demos and Slack communication
- CI/CD with GitHub Actions, Sentry, CloudWatch
How We Build Custom SaaS: The IRPR Process
Every project follows a four-phase process that eliminates guesswork.
Phase 1: Idea validation and technical discovery. We map your requirements, user flows, and data model. Phase 2: Roadmap with wireframes, tech stack, and a fixed-price quote for the full build. The Roadmap costs $8K and takes 2 weeks.
Phase 3: Build sprint in 2-week iterations. You see working software every 14 days. Phase 4: Release with deployment, monitoring, and a 30-day warranty. We push to production on AWS ECS or your own cloud.
What Ships with Every Custom SaaS from IRPR
You get more than just code. Every delivery includes production infrastructure.
Our goal is to make you self-sufficient on day one. That means a deployable app, not a zip file. We include everything a modern SaaS needs to run and scale.
You own the code, the pipeline, and the infrastructure. No lock-in, no hidden fees, no recurring charges for maintenance unless you want it.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Sentry error tracking and performance monitoring
- CloudWatch dashboards and alarms
- Unit and integration tests (80%+ coverage)
- Swagger/OpenAPI documentation for backend APIs
- Docker and docker-compose for local development
- Staging environment on AWS with production parity
- Admin panel for user and subscription management
- Written deployment and runbook documentation
