Why You Need Experienced Custom SaaS Development Developers
Your SaaS needs more than basic coding - it needs architecture that scales, billing that works, and compliance that passes audits.
IRPR has shipped 200+ SaaS products since 2016. Our developers have built subscription platforms handling 1 million+ invoices per month. We use proven stacks: React/Next.js on the frontend, Node.js on the backend, PostgreSQL for data, and Stripe for payments.
Every project starts with a fixed-price Roadmap phase (week 2). You know exactly what you get and what it costs before we write a line of production code. We include CI/CD, error tracking (Sentry), uptime monitoring (Datadog), and documentation by default.
Generic Dev Shop vs. Experienced Custom SaaS Development Developers
Not every agency can architect a multi-tenant subscription platform. Here is the real difference.
Most dev shops treat SaaS like any other web app. They miss critical pieces like tenant isolation, billing logic, and subscription lifecycle management. IRPR builds SaaS from day one with these foundations.
We also handle compliance from the start. Healthcare SaaS gets HIPAA. Fintech SaaS gets PCI-DSS. Enterprise SaaS gets SOC 2. No retrofitting. No surprises.
- hourly billing that blows budgets
- no multi-tenant architecture
- Stripe or billing not integrated
- zero compliance planning
- no CI/CD or monitoring
- code ownership unclear
- fixed price from Roadmap phase
- fully isolated multi-tenant with PostgreSQL
- Stripe, Recurly, or Chargebee built in
- HIPAA, PCI-DSS, SOC 2 ready
- GitHub Actions CI/CD + Sentry + Datadog
- you own 100% of the code
How Our Experienced Custom SaaS Development Developers Work
We follow a four-phase process that turns your idea into a live, revenue-generating SaaS product.
Phase one is Idea Validation. We scope your concept into a written technical specification with wireframes. You get a fixed price and timeline before any code is written. This phase takes 1 week.
Phase two is Roadmap. We define every user story, API endpoint, and database table. You approve the roadmap, and we lock the price. No scope creep. Phase three is Product - 8 to 12 weeks of sprint-based development with weekly demos. Phase four is Release - CI/CD pipeline, DNS setup, monitoring, and a 30-day warranty.
What Ships with Every Custom SaaS from IRPR
When you work with experienced custom SaaS development developers, you get a production-ready system, not just code.
Every project includes infrastructure, documentation, and monitoring. You do not need to hire a DevOps engineer or a QA team. We give you everything your team needs to run the SaaS in production.
We also include a 30-day warranty after launch. If anything breaks or needs tweaking, we fix it at no extra cost. After that, we offer ongoing engineering at a monthly retainer if you want to keep iterating.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions
- Sentry error tracking with alerts
- Datadog uptime and performance monitoring
- Stripe integration for subscription billing
- Swagger or GraphQL documentation for APIs
- Docker containers and AWS deployment scripts
- Admin dashboard for managing users and subscriptions
- 30-day post-launch warranty
