Why hire premium custom SaaS development consultants
Building a SaaS product is about more than code. It is about architecture, compliance, and go-to-market readiness.
IRPR delivers a production-ready SaaS that handles authentication, billing, team management, and monitoring out of the box. We use Next.js for frontend, Node.js or Python for backend, and PostgreSQL for persistence. Every deployment includes containerized microservices on AWS ECS with CI/CD via GitHub Actions.
Our teams have shipped over 200 SaaS products across 50 countries. We specialize in multi-tenant architectures that scale from 10 users to 10,000 without rewrites. Each project uses Stripe for billing, Sentry for error tracking, and DataDog for monitoring.
The difference between generic agencies and premium SaaS consultants
Most agencies treat your SaaS like a brochure site. IRPR treats it like a product that needs to ship fast and scale fast.
Generic dev shops reuse templates and avoid architectural decisions. They bill hourly and scope creep is common. You end up with a monolithic codebase that cannot handle multi-tenancy or compliance audits.
IRPR builds each SaaS from scratch with the right architecture from day one. We enforce code reviews, automated testing, and infrastructure-as-code. Every project includes a fixed price and roadmap with clear milestones.
- Hourly billing with no cap
- No dedicated product manager
- Reuses unmaintained code
- No compliance knowledge
- Scope creep on every feature
- No post-launch monitoring
- Fixed price from Roadmap phase
- Senior engineers + PM on every project
- Multi-tenant architecture from day one
- Built for HIPAA, SOC 2, PCI-DSS
- Roadmap with weekly milestones
- Monitoring with Sentry and DataDog
Our SaaS development phases
We follow a four-phase process to get from idea to production in 8-12 weeks.
Phase 1 is the Idea call. We align on goals, compliance, and target users. Phase 2 is the Roadmap where we deliver a fixed-price quote, wireframes, and a 12-week timeline. Phase 3 is Product build with two-week sprints and weekly demos.
Phase 4 is Release including deployment on your AWS account, CI/CD setup, and a one-week warranty. You own the full source code, infrastructure config, and documentation.
What ships with your SaaS
Every project includes more than code. You get a complete production environment.
IRPR does not hand off a code zip file. We deploy the SaaS on your AWS account with all infrastructure managed as Terraform code. You can maintain it yourself or we can continue with a support retainer.
The codebase includes unit tests, integration tests, and a test suite that runs on every pull request. Documentation covers architecture decisions, API endpoints, and how to scale.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Infrastructure-as-code with Terraform (AWS)
- Multi-tenant database schema with PostgreSQL
- Stripe integration for subscription billing
- Auth0 or NextAuth for user authentication
- Sentry error tracking and DataDog monitoring
- API documentation (OpenAPI/Swagger)
- Unit and integration tests (80%+ coverage)
- Deployment runbook and architecture diagrams
