Why custom Enterprise Shopify platforms matter
Off-the-shelf themes cap your growth. A custom platform scales with your revenue.
IRPR builds Shopify Plus platforms that handle 10K+ orders daily without slowdown. We use headless architecture to separate frontend from backend, so your store stays fast during traffic spikes. One client saw a 40% increase in conversion after moving from a theme to a custom headless build.
Our platforms include custom checkout flows, ERP integrations, and B2B portals. We ship in 12 weeks with a fixed price, so you know the cost upfront. Every project includes PCI-DSS compliance and 99.9% uptime guaranteed.
Generic dev shop vs IRPR: the difference
Most agencies build Shopify stores like cookie-cutter templates. IRPR builds custom platforms that own your data and scale.
Generic dev shops often use hourly billing and change scope mid-project. They lack deep Shopify Plus knowledge and compliance experience. You end up with a slow store built on a theme with no source code ownership.
IRPR delivers fixed-price projects with a clear roadmap. We assign senior engineers who know Shopify Plus APIs, headless architecture, and PCI-DSS. You get full source code, a CI/CD pipeline, and post-launch support for 12 months.
- Hourly billing with no cap
- Scope creep and delayed timelines
- No PCI-DSS compliance knowledge
- Generic Shopify themes with limited customization
- No post-launch support
- No source code ownership
- Fixed price from $80K to $250K
- 12-week delivery guarantee
- PCI-DSS compliant by default
- Headless architecture with React/Next.js

How we build your custom Enterprise Shopify platform
Four phases from discovery to launch. No surprises, no delays.
We start with a 2-day discovery sprint where we map your business logic, integrations, and user flows. By the end of week 2, you have a detailed roadmap with fixed price and timeline.
Our senior engineers build the platform in 8-10 weeks using Shopify Plus, Hydrogen, and your chosen ERP. We test every endpoint and deploy via GitHub Actions. You get a launch-ready platform with documentation.
What ships with every custom Enterprise Shopify platform
You get more than code. You get a production-ready system with tooling built in.
Every IRPR project includes everything needed to run and maintain the platform. No hidden handoffs, no missing pieces. Your team can start managing the store from day one.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Shopify Plus API integration (REST + GraphQL)
- Custom Liquid components and templates
- Headless frontend with React or Next.js
- Automated test suite (Cypress + Jest)
