Why choose an experienced custom SaaS development company
IRPR has shipped over 200 SaaS products across 50 countries, each built under a fixed-price contract with senior engineers only.
We use a proven process: idea validation, roadmap, product build, and release. Every sprint delivers working software that you own from day one. Our average MVP takes 12 weeks from kickoff to deployment.
Compliance is built in, not bolted on. If your SaaS needs SOC 2, HIPAA, or PCI-DSS, we implement controls during development. We also set up monitoring, error tracking, and CI/CD pipelines as standard.
How IRPR is different from generic dev shops
Most agencies bill hourly, change out developers, and leave you with messy code. IRPR does the opposite.
Every project is staffed with senior-level engineers who stay on your project from start to finish. We give you a fixed price in week 2 during the Roadmap phase. No surprises, no scope creep.
Our engineers have an average of 10+ years of experience. They have built production SaaS apps for finance, healthcare, and real estate. You get code that scales, not a prototype that needs a rewrite.
- bills hourly, no cap
- rotates junior developers
- delivers code without tests
- ignores compliance until audit
- no monitoring or error tracking
- hands off incomplete docs
- fixed price from week 2
- senior engineers only, no swaps
- 100% test coverage in CI
- compliance built in (SOC 2, HIPAA, PCI)
- Sentry, DataDog, CI/CD included
- full runbooks and architecture docs
The IRPR process for custom SaaS development
From idea to deployed SaaS in 4 phases, each with clear deliverables and go/no-go gates.
We break every SaaS project into four stages: Idea, Roadmap, Product, Release. Each stage ends with a decision point. You can stop, pivot, or proceed with full confidence.
The Roadmap phase takes 1-2 weeks and produces a fixed-price quote, technical design, and launch timeline. No code is written until you approve the plan.
What ships with every custom SaaS project
Source code, infrastructure, and documentation - all yours to own and operate.
We don't hand over a black box. Every project includes production-ready code, automated tests, and cloud infrastructure defined in Terraform. You can deploy, modify, and scale without depending on IRPR.
Documentation covers architecture decisions, API endpoints, environment variables, and runbooks for common tasks like backup restore and scaling events.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Infrastructure as code (Terraform) for AWS
- Sentry error tracking configured
- DataDog monitoring dashboards
- API documentation (Swagger/OpenAPI)
- Database migration scripts
- Load testing results
- Security audit report (OWASP top 10)
- Post-launch support schedule

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the exact cost before any code is written.
Senior engineers only
Our team averages 10+ years of professional experience. We never use junior developers or offshore factories. Every engineer has shipped multiple production SaaS products.
12-week MVP guarantee
Most SaaS MVPs ship in 10-14 weeks. We hold to a fixed timeline with a launch date agreed in week 1. Delays are our problem, not yours.
Compliance built in, not bolted on
We design for SOC 2, HIPAA, and PCI from the start. Audit logs, encryption, and data segregation are part of the architecture, not afterthoughts.
Full code ownership
You get 100% of the source code, infrastructure templates, and documentation. No license fees, no vendor lock-in. You can take it anywhere.
Post-launch support included
Every project includes 30 days of post-launch support with response times under 4 hours. We help you handle early user feedback and fix any issues.
