Why brands choose IRPR for Shopify Plus development
We have shipped 200+ ecommerce projects, and every one went live on time.
Our team of senior engineers has built Shopify Plus stores for brands processing $50M+ in annual revenue. We use Hydrogen for headless frontends, custom Liquid for theme overrides, and the Storefront API for real-time product data. Every store meets PCI-DSS Level 1 compliance from day one.
We do not outsource. Every developer is based in the US or Europe and works directly with your team. You get a fixed price quote in week 2 after a 4-day roadmap sprint. No hourly billing, no surprises.
The IRPR difference for Shopify Plus development
Most agencies bill by the hour and deliver late. We do the opposite.
Generic Shopify agencies often use pre-built themes that break under high traffic. They charge hourly, so scope creep becomes their profit center. When you need a custom checkout flow or a headless frontend, they say 'that will take 3 months' and bill you for every hour.
IRPR works differently. We give you a fixed price after a 4-day roadmap sprint. We build everything from scratch using Shopify's latest APIs. Your store handles 10,000+ orders per day without slowdown. And we ship in 8-12 weeks, not 6 months.
- Bills hourly, scope creep is common
- Uses pre-built themes that break under load
- No dedicated project manager
- Outsources to junior developers
- Code ownership is unclear
- Takes 6+ months for a custom build
- Fixed price quoted in week 2
- Custom Hydrogen or Liquid build from scratch
- Dedicated PM with weekly standups
- Senior engineers only, no junior staff
- Full source code ownership on day one
- 8-12 week delivery for a production store
How we build your Shopify Plus store in 8-12 weeks
Our process has 4 phases. You see progress every week.
We start with a 4-day roadmap sprint where we map every feature, integration, and data migration step. You get a fixed price quote and a timeline before any code is written. No surprises.
Then we build in 2-week sprints. You review a staging environment every sprint. By week 8, your store is ready for QA. By week 12, it is live and processing orders.
What ships with every Shopify Plus build
You get more than a store. You get a complete operational system.
Every IRPR build includes source code, CI/CD pipelines, and monitoring. We do not hand you a zip file and walk away. You own everything from day one.
We also include documentation for your team: how to add products, how to run reports, and how to manage integrations. No black boxes.
- Full source code in your GitHub repo
- CI/CD pipeline with GitHub Actions and Shopify CLI
- Staging environment on Shopify Oxygen or Vercel
- Sentry error tracking and New Relic performance monitoring
- Automated test suite for checkout and inventory
- PCI-DSS Level 1 compliance documentation
- Admin user manual with screenshots
- 30-day post-launch support with 4-hour SLA
