Why hire an experienced custom SaaS development agency
IRPR delivers production-ready SaaS with senior engineers and fixed pricing.
Generic dev shops hand off projects to junior developers and bill hourly. IRPR assigns a dedicated team of senior engineers who own the product from start to ship. Our fixed-price model means you know the cost upfront with no surprises.
We build SaaS platforms that handle compliance from day one. SOC 2, HIPAA, or PCI-DSS requirements are scoped in the Roadmap phase. Your data stays secure with encryption at rest and in transit, plus automated vulnerability scanning.
The difference between a generic dev shop and an experienced SaaS agency
IRPR is an experienced custom SaaS development agency with a repeatable process.
Generic agencies treat every project as a new puzzle. They lack SaaS-specific patterns like multi-tenancy, subscription billing, and usage-based pricing. Engineers often lack experience scaling to thousands of users.
IRPR has built 200+ SaaS products across 50 countries. Our codebases include reusable modules for auth, billing, roles, and onboarding. We ship faster because we reuse proven patterns.
- Hourly billing with unknown total cost
- Junior and mid-level engineers on your project
- No SaaS architecture patterns
- Slow communication across time zones
- Code quality not audited for compliance
- No dedicated project manager
- Fixed price locked from the Roadmap phase
- Senior engineers only (10+ years average)
- SaaS patterns: multi-tenant, Stripe integration, RBAC
- Async-first communication with daily overlap hours
- SOC 2 / HIPAA / PCI-DSS built into delivery
- Dedicated PM with weekly progress reports
Our process for building your custom SaaS platform
From idea to release, we follow a proven 4-phase process.
Every project starts with the Idea phase where we map out your requirements. We align on features, compliance needs, and integrations before writing a line of code.
After the Roadmap phase, we begin building in 2-week sprints. Each sprint ends with a deployable increment. You see progress every 14 days.
What ships with every SaaS product
Every engagement delivers a full-production software suite.
We don't just deliver code. You get a running system with monitoring, deployment pipelines, and admin tools. Everything is documented and transferable.
Our deliverables include source code, infrastructure-as-code, and runbooks. Your internal team can operate the platform from day one.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Sentry error tracking with alerting
- Datadog or CloudWatch monitoring dashboard
- Staged deployment environment (staging + production)
- Stripe billing integration (subscriptions or usage-based)
- Auth system with OAuth 2.0 (Google, GitHub, custom)
- Admin panel for managing users and subscriptions
- API documentation (Postman collection or OpenAPI spec)
- Infrastructure-as-code using Terraform or CloudFormation
What we ship in this practice.

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.
Senior engineers only
Our team averages 12 years of experience. No juniors or mid-levels. Every engineer has shipped at least 10 SaaS projects in production.
Async-first with daily overlap
We work across 50+ countries but maintain 4 hours of daily overlap with US time zones. You get Slack access and a weekly video call.
Compliance built into the roadmap
SOC 2, HIPAA, or PCI-DSS requirements are scoped in the Idea phase. We deliver audit-ready infrastructure and documentation.
Dedicated project manager
Each project has a PM who tracks progress in Jira, runs daily standups, and sends a weekly report. You never wonder where things stand.
You own everything
Full source code, infrastructure, IP, and all generated assets belong to you. No licensing fees, no lock-in. You can take over at any time.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
