Custom SaaS Development ConsultantsDevelopment Consultants
We build your SaaS product from idea to launch in 8-12 weeks. Fixed price, no hourly billing, full code ownership.
IRPR is a team of senior engineers who act as custom SaaS development consultants. We build multi-tenant SaaS platforms using Next.js, React, Node.js, Python, AWS, and Stripe. Every project starts with a fixed-price Roadmap phase where we define the architecture, data model, and integration points before writing a single line of code.
We ship production-ready SaaS products in 8-12 weeks. Pricing starts at $80K and goes to $250K depending on complexity and compliance needs. We handle SOC 2 Type II, HIPAA, and PCI-DSS certifications for healthcare, fintech, and enterprise SaaS clients. Our team has shipped over 200 products across 50+ countries.
We work with founders who have a validated idea and need a technical co-founder replacement. We work with CTOs who need to scale their engineering team without hiring. We work with product managers who need to ship a compliant SaaS platform under a fixed budget and timeline.

Why you need custom SaaS development consultants
Building a SaaS product is not the same as building a website. It requires multi-tenant architecture, subscription billing, and scalable infrastructure from day one.
Most development agencies build single-tenant applications and call it SaaS. That approach breaks when you add a second customer. IRPR designs multi-tenant systems using PostgreSQL row-level security and AWS ECS with auto-scaling. We also handle Stripe integration for recurring billing, usage metering, and invoicing.
We have shipped over 200 SaaS products across 50 countries. Our average MVP timeline is 12 weeks. 98% of our projects deliver on time. We use a fixed-price model so you know the cost before we start building.
How we differ from generic SaaS developers
Most agencies treat your SaaS project like a fixed-scope website. We treat it like a product that needs to scale, bill, and comply.
Generic dev shops build what you ask for, then hand you an invoice for extra hours when you need multi-tenancy or Stripe Connect. IRPR builds the foundation for scale from week one. Our Roadmap phase (week 1-2) defines the data model, tenant isolation strategy, and billing integration before we write code.
We also handle compliance certifications. If you need HIPAA, PCI-DSS, or SOC 2, we build the controls into the architecture. We do not add compliance as an afterthought.

Our SaaS development process
We follow a four-phase process that turns your idea into a production SaaS product in 12 weeks.
Each phase has a fixed deliverable and a fixed price. You approve the work before we move to the next phase. No surprises, no scope creep.
We use agile sprints with weekly demos. You see the product every Friday. Feedback gets incorporated into the next sprint.

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 the first line of code.
Senior engineers only
Our team averages 10+ years of experience. Every engineer has shipped at least 5 SaaS products. We do not outsource or use junior developers. You talk directly to the engineers building your product.
Compliance built in, not bolted on
We build HIPAA, PCI-DSS, and SOC 2 controls into the architecture from day one. No retrofitting. No compliance delays. We have passed 3 SOC 2 audits without a single finding.
Full code ownership
You own everything we build. Source code, infrastructure as code, CI/CD pipelines, and documentation. No licensing fees, no vendor lock-in. You can take the product to any team after launch.
8-12 week MVPs
We ship production-ready SaaS products in 8-12 weeks. Our record is 6 weeks for a billing platform. We use proven frameworks and templates to accelerate development without cutting corners.
Post-launch support included
