We build high-volume Shopify Plus stores with headless frontends and ERP integrations. 12-week delivery at a fixed price.
IRPR builds Shopify Plus stores for brands that need more than a basic theme. We use Hydrogen, Remix, and the Shopify Storefront API to create headless frontends that load in under 2 seconds and handle 10,000+ orders per day.
Every project ships in 12-14 weeks with a fixed price between $80K and $250K. We handle PCI-DSS compliance, ERP integration (NetSuite, SAP, Microsoft Dynamics), and custom checkout flows. Source code is delivered to your GitHub repo on day one.
Our clients include DTC brands scaling past $10M in revenue, B2B manufacturers needing wholesale portals, and omni-channel retailers syncing inventory across 50+ locations. Each gets a dedicated senior engineer and a fixed quote before any code is written.

Why brands choose IRPR for Shopify Plus development services
We have shipped 200+ products across 50 countries, and every Shopify Plus project meets the same standard.
IRPR assigns senior engineers who have built Shopify Plus stores for brands doing $50M+ in annual revenue. We do not use junior developers or offshore teams. Every line of code is reviewed, tested, and documented before deployment.
Our fixed-price model means you know the cost before we start. The Roadmap phase (week 2) produces a detailed scope with a firm quote. No hourly billing, no surprise change orders.
Generic Shopify agencies vs IRPR
Most agencies charge by the hour and hand off your project to junior developers. IRPR does the opposite.
When you hire a generic Shopify agency, you often get a project manager who knows nothing about code, a junior developer learning on your dime, and a timeline that slips by months. They charge by the hour and change scope to inflate the bill.
IRPR gives you a senior engineer who has built 10+ Shopify Plus stores. You get a fixed price from week 2, weekly demos, and full source code ownership. No handoffs, no surprises.
- Junior developers with 1-2 years of Shopify experience
- Hourly billing with no cap
- Scope creep disguised as 'change requests'
- No dedicated engineer — you talk to a PM
- No compliance review (PCI-DSS ignored)
- Source code held hostage until final payment
- Senior engineers with 10+ Shopify Plus projects each
- Fixed price from the Roadmap phase (week 2)
- Scope locked in writing — no hidden costs
- Your engineer is your point of contact
- PCI-DSS compliance built into every project
- Full source code in your GitHub repo on day one
How we deliver your Shopify Plus store
Our process moves from idea to production in 12 weeks. Here are the four phases.
Every project starts with a 2-week Discovery phase where we map your business logic, data sources, and integration points. We produce a written Roadmap with a fixed price and timeline.
After you approve the Roadmap, we build your store in 8-10 weeks using weekly sprints, daily standups, and a staging environment you can see every Friday.
What ships with every Shopify Plus project
Every deliverable is concrete and measurable. You get these items by default.
IRPR does not hand over a zip file. You get a fully documented, production-ready codebase with CI/CD pipelines, monitoring, and compliance reports. Everything below is included in the fixed price.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and Vercel or Shopify Oxygen
- Sentry error tracking and Datadog monitoring
- Load test report with 10,000 concurrent users
- PCI-DSS compliance checklist and audit trail
- SEO audit with Lighthouse score 90+ on mobile and desktop
