Why hire professional custom SaaS development consultants
Building a SaaS platform is a complex process that requires experienced engineers and a clear plan.
IRPR has shipped over 200 SaaS products. Our team of senior engineers has built platforms for startups, mid-market companies, and Fortune 500 clients. We use a proven 4-phase process: Idea, Roadmap, Product, Release.
In the Roadmap phase (week 2), we deliver a fixed-price quote and a detailed technical specification. No surprises. No scope creep. You know exactly what you get and when you get it.
How IRPR differs from generic development shops
Not all SaaS development agencies are the same. Here is what sets IRPR apart.
Generic shops bill by the hour and change scope mid-project. They use junior developers and outsource testing. You end up with a product that is late, over budget, and full of bugs.
IRPR gives you a fixed price after a 2-week Roadmap phase. Our senior engineers write every line of code. We handle DevOps, security, and compliance from day one. You get a production-ready platform with full code ownership.
- Hourly billing with no cap
- Junior developers on your project
- Scope creep without change orders
- No compliance or security review
- Unclear timeline, often 6+ months
- You do not own the code
- Fixed price after Roadmap phase
- Senior engineers only, average 10+ years
- Scope locked in week 2
- HIPAA, PCI-DSS, SOC 2 built in
- 12-14 week delivery
- Full code ownership from day 1
Our 4-phase process for custom SaaS development
We follow a repeatable process that reduces risk and speeds up delivery.
Every project starts with the Idea phase, where we align on goals, users, and core features. This takes 1 week. Then we move to the Roadmap phase, where we produce a detailed spec and a fixed price.
The Product phase is where we build. We work in 2-week sprints, deploying to a staging environment every sprint. The Release phase includes production deployment, CI/CD setup, and a 30-day warranty.
What ships with every custom SaaS platform
Every SaaS product we build includes these deliverables by default.
You get more than just a working app. We set up your infrastructure, monitoring, and CI/CD pipeline so you can scale without rebuilding. All code is in your GitHub or GitLab repository from day one.
We also include a 30-day warranty after launch. If you find a bug, we fix it at no cost. After that, we offer ongoing maintenance at a flat monthly rate.
- Full source code in your GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Production deployment on AWS or GCP
- Sentry error tracking and Datadog monitoring
- SSL certificate and custom domain setup
- User authentication with Auth0 or Clerk
- Stripe or Paddle payment integration
- Admin dashboard with user management
- API documentation with Swagger or Postman
- 30-day post-launch warranty

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 total cost before we write a line of code.
Senior engineers only
Our team averages 10+ years of experience. Every engineer has shipped production SaaS platforms before. No juniors, no offshore code mills, no learning on your dime.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliance into the architecture from day one. You do not need to retrofit security later. We handle audits and documentation.
Full code ownership
You own every line of code we write. No licensing fees, no lock-in, no recurring revenue share. The code is in your repository from the first commit.
12-14 week delivery
We ship production-ready SaaS platforms in 12-14 weeks. Our process is designed to move fast without cutting corners. 98% of our projects deliver on time.
Post-launch support
