Why choose an expert SaaS product development firm
Building a SaaS product requires more than code. It needs architecture that scales, billing that works, and compliance that holds.
IRPR has shipped over 200 products across 50 countries. Our engineers have built SaaS platforms that handle 10 million API calls per day and process $50M in transactions annually. Every project starts with a 2-week Roadmap phase where we define scope, tech stack, and a fixed price.
We use battle-tested stacks: Next.js on Vercel, Node.js or Python on AWS, PostgreSQL or DynamoDB, Stripe or Chargebee for payments, and Sentry for error tracking. All projects include CI/CD pipelines and staging environments.
How we differ from other SaaS development agencies
Most agencies bill by the hour and change scope. IRPR gives you a fixed price and a clear timeline.
We see companies that get burned by agencies that underbid, then add change orders. They lose time and budget. Our approach eliminates that entirely.
After the Roadmap phase, we lock the scope and price. You get a single estimate, not a billing spreadsheet. We also hand over full source code and DevOps configuration from day one.
- hourly billing with no cap
- scope creep without change orders
- vague timelines that slip
- junior or offshore engineers
- no compliance guidance
- code kept in house until final payment
- fixed price after 2-week Roadmap
- scope frozen before development begins
- 8-12 week delivery, 98% on-time
- senior engineers only (10+ years)
- SOC 2, HIPAA, PCI-DSS built in
- full code ownership from kickoff
Our process for building your SaaS product
From idea to release in four phases. Each phase has a clear deliverable and a fixed cost.
Phase 1: Idea validation and research. We analyze your market, competitors, and technical risks. You get a feasibility report within two weeks.
Phase 2: Roadmap and architecture. We design the system, define user stories, select the tech stack, and produce a fixed-price proposal. This takes two weeks.
What you get when you build with IRPR
Every deliverable is designed to make your team self-sufficient after launch.
We do not leave you with a black box. Every project includes the full codebase, complete documentation, and a working CI/CD pipeline. You can hire your own engineers and keep building.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline on GitHub Actions or AWS CodePipeline
- Staging and production environments on AWS or Vercel
- Sentry error tracking and performance monitoring
- PostgreSQL or DynamoDB database schema
- Stripe or Chargebee billing integration (if needed)
- Auth0 or Clerk user authentication
- Postman API documentation and test suite
- Figma design files and UI component library
- SLA for uptime and support (99.9% uptime)

Compliance built in
We have built products that pass SOC 2 audits, HIPAA privacy rules, and PCI-DSS Level 1. Compliance is part of the architecture, not an afterthought.
