Ship your multi-tenant B2B SaaS platform in 12 weeks. Fixed price, senior engineers, full compliance.
IRPR is the top b2b saas development firm for founders and enterprises who need production-grade platforms. We build with React, Node.js, Python, and AWS, and ship on time with a fixed price.
Every project delivers a full-stack SaaS in 8-12 weeks with pricing from $80K to $250K. We handle HIPAA, PCI-DSS, and SOC2 compliance out of the box, so you can sell to regulated industries from day one.
Our clients are SaaS founders who need a v1 to raise seed funding, enterprise product managers replacing legacy systems, CTOs at Series A startups scaling their tech, and venture studios spinning out new B2B ventures.
A branded portal where your clients log in to manage their account, see invoices, and submit support tickets. Integrates with Stripe and Salesforce.
Track API calls, seats, or storage with real-time metering. Generate invoices and enforce limits via Stripe Billing.
Custom dashboards with charts, CSV exports, and role-based views. Built with D3.js and Cube.js for live querying.
One backend serving hundreds of customers with isolated data. Uses Postgres row-level security and dedicated subdomains.
Handle trials, upgrades, downgrades, and cancellations with Stripe webhooks. Sync plans across users and teams.
Rate-limited, authenticated API layer for your product. Includes Swagger docs, usage logs, and developer keys.
Admin dashboards, workflow automation, and data entry apps for your ops team. Connected to your existing databases via Retool or custom React.
A platform you can rebrand and resell to your clients. Includes tenant onboarding, custom domains, and feature flags per tenant.
We ship production-grade B2B SaaS platforms faster and with fewer defects than generic dev shops.
IRPR has delivered over 200 products across 50+ countries, with 98% of projects finishing on time. Our developers average 10+ years of experience and have built SaaS platforms handling millions of API calls per day.
We use a fixed-price framework called Idea-Roadmap-Product-Release. In week 2 you get a detailed roadmap with wireframes and a fixed quote. No hourly billing, no scope creep. The average project costs between $80K and $250K.
Most agencies bill hourly and change scope. We fix the price and the timeline up front.
A typical development relationship starts with a vague estimate and ends with change orders. IRPR inverts this: we spend Week 2 building a roadmap with wireframes and a binding fixed price.
Our clients get full code ownership, a CI/CD pipeline, and a 30-day warranty after launch. We also include Sentry error tracking and Datadog monitoring so you know exactly how your platform performs.
Four phases from idea to production – each with a clear milestone and decision point.
Phase 1 (Idea) is a 3-day workshop where we define user personas, core workflows, and compliance needs. Phase 2 (Roadmap) delivers a fixed-price plan with wireframes by end of week 2.
Phase 3 (Product) is a 8-12 week build sprint with weekly demos. Phase 4 (Release) includes staging, production deployment, and a 30-day warranty with monitoring.
Every project includes the following deliverables – no add-ons, no hidden fees.
When you hire IRPR as your top b2b saas development firm, you get a fully production-ready platform. We don't just hand over code; we hand over a running system with monitoring and documentation.
All source code is placed in your GitHub repository from the first commit. You own everything – no IP restrictions, no license fees.
