Why work with top custom SaaS development consultants
Choosing the right consultants means your SaaS ships on time, on budget, and with the right architecture from day one.
Generic development shops often overcharge hourly and miss critical SaaS patterns like subscription billing, multi-tenancy, and usage metering. IRPR's senior engineers have built over 200 SaaS products across financial, healthcare, and enterprise verticals. We use proven stacks: React, Node.js, PostgreSQL, AWS, and Stripe.
Our consultants write code and make architecture decisions that reduce future technical debt. Every project includes automated testing, CI/CD with GitHub Actions, and monitoring with Sentry and Datadog. You get source code ownership and full documentation.
How IRPR differs from other SaaS consultants
Most agencies bill hourly and change scope. IRPR works with a fixed price and a clear Roadmap.
We start every engagement with a 2-week Roadmap phase where we define features, architecture, timelines, and a fixed price. No hourly billing, no surprise overruns. You know the total cost before we write a single line of production code.
Our team includes senior engineers only — no juniors, no offshore B-team. You work directly with the people building your product. We communicate daily via Slack and hold weekly sprint reviews.
- Hourly billing with uncertain final costs
- Junior devs assigned to your project
- No compliance expertise (HIPAA, SOC 2)
- Long discovery phases without delivery
- Code handed over with no CI/CD or monitoring
- Hard to reach after launch
- Fixed price after 2-week Roadmap
- All senior engineers, no juniors
- Built-in compliance for SOC 2, HIPAA, PCI-DSS
- 8-12 week MVP delivery
- Full CI/CD, Sentry error tracking, Datadog monitoring
- Slack-based support for 30 days post-launch
Our SaaS development process
From idea to release, we follow a structured 4-phase process that every top custom SaaS development consultant should use.
Phase 1 is the Idea workshop where we align on user personas, core features, and success metrics. Phase 2 is the Roadmap — a 2-week engagement that produces a detailed scope, architecture diagram, and fixed price proposal.
Phase 3 is Product build: 6-10 weeks of iterative development with weekly demos. Phase 4 is Release: deployment to production, CI/CD pipeline handover, and 30 days of post-launch support. We use Stripe for billing, AWS for hosting, and Auth0 for authentication in most projects.
What ships with every SaaS project
Every custom SaaS build includes these deliverables as standard — no extra cost.
You don't need to ask for these. They are part of every engagement because we believe production-ready software requires more than just code. Each deliverable helps your team maintain and scale the product.
We set up your cloud infrastructure on AWS or GCP, configure CI/CD pipelines, and install monitoring tools. All source code is placed in your GitHub repository with full commit history.
- Source code in your GitHub repo with full history
- CI/CD pipeline on GitHub Actions with automated tests
- Staging and production environments on AWS or GCP
- Sentry error tracking with alert rules
- Datadog monitoring for uptime and performance
- Stripe integration for subscription billing (auth, webhooks, invoicing)
- Authentication and authorization (Auth0 or Cognito)
- API documentation (Postman collection or OpenAPI spec)
- Database migration scripts with rollback support
- Deployment runbook and architecture decision records
