Senior Custom SaaS Development VendorVendor
We build your SaaS product with senior engineers only. Fixed price, 8-12 week MVP, and full code ownership.
IRPR is a senior custom SaaS development vendor. We build multi-tenant platforms, API-first backends, and B2B portals using React, Node.js, AWS, and PostgreSQL. Every project starts with a clear Roadmap and ends with a production-ready SaaS product.
Our standard timeline is 8 to 12 weeks for an MVP. Fixed pricing ranges from $80,000 to $250,000 depending on scope. We handle compliance out of the box — HIPAA for healthcare, PCI-DSS for payments, SOC 2 for enterprise data.
We work with three buyer personas: SaaS founders raising seed to Series A who need a scalable product fast; enterprise teams replacing legacy systems with modern SaaS; and regulated startups (healthtech, fintech) that require built-in compliance from day one.

Why choose a senior custom SaaS development vendor
Not all development teams deliver the same level of quality and speed.
A senior custom SaaS development vendor brings engineers with 10+ years of experience. IRPR has shipped over 200 SaaS products across 50 countries. We use modern stacks like React, Node.js, AWS, and PostgreSQL to build scalable multi-tenant systems.
Our 8-12 week MVP timeline lets you test your idea fast. We charge a fixed price after the Roadmap phase. No hourly billing, no scope creep. You get full code ownership and a CI/CD pipeline from day one.
How we differ from generic development shops
Most vendors promise senior talent but deliver junior engineers. IRPR is different.
Generic shops often assign junior developers to cut costs. You end up with technical debt, missed deadlines, and a product that doesn't scale. Compliance is usually an afterthought.
IRPR assigns only senior engineers with 10+ years of experience. We build compliance (HIPAA, PCI-DSS, SOC 2) into the architecture from week one. Our fixed price model means no surprises. You get a production-ready SaaS product in 8-12 weeks.

Our 4-phase process for custom SaaS development
From idea to release in 8-12 weeks with a clear, fixed-price plan.
Every project follows our Idea - Roadmap - Product - Release framework. We start with a discovery call to understand your market and technical requirements. Then we produce a detailed Roadmap with wireframes, tech stack, and a fixed price.
The Product phase is where we build your MVP in 8-12 weeks. We deploy on AWS with auto-scaling, CI/CD, and monitoring. After Release, we hand over full code ownership and offer optional maintenance.
What ships with every senior custom SaaS build
You get a production-ready SaaS product, not just code.
Every project includes a fully deployed and tested application. We set up your infrastructure on AWS with auto-scaling, monitoring, and security best practices. You also get a CI/CD pipeline so you can ship updates yourself.
All source code is in your private GitHub repo. We include documentation, API specs, and a runbook for your team. No hidden dependencies.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- AWS infrastructure with auto-scaling
- Sentry error tracking
- SSL/TLS and encryption at rest
- API documentation (Swagger/OpenAPI)
