Why outsource Shopify Plus development to IRPR
We have built 200+ ecommerce stores with measurable results.
Every store we build is tested against real traffic patterns. We use Lighthouse CI to enforce performance budgets and deploy with zero-downtime rollouts via Oxygen.
Our clients see average conversion rate improvements of 15% after migration. We guarantee 99.9% uptime because we monitor every store with Sentry and Datadog.
Generic Shopify agency vs IRPR
Most agencies charge hourly and miss deadlines. We deliver fixed price, on time.
Generic dev shops often assign junior developers who don't know Shopify API limits. They build on top of free themes, skip compliance, and hand you a codebase you don't own.
IRPR assigns senior Shopify Plus developers with 5+ years experience. We build from scratch, own nothing, and give you full source code. Every project includes PCI-DSS, a 12-week ship window, and a fixed quote.
- hourly billing with no cap
- junior or mid-level developers
- no PCI-DSS or SOC 2 knowledge
- uses off-the-shelf theme with heavy modification
- code stays on their servers until you pay final invoice
- 9-18 month delivery, over 50% over budget
- fixed price after Roadmap (week 2)
- senior Shopify Plus engineers only
- PCI-DSS Level 1 compliance built in
- custom Hydrogen or Liquid theme from scratch
- source code in your GitHub repo from day one
- 8-12 week ship, 98% on-time
Our process for Shopify Plus development
We break the build into four clear phases, each with a deliverable.
The process starts with a two-week Idea phase where we validate your concept and review data from existing stores. Then we move into Roadmap for technical specs and a fixed quote.
During Product phase we work in two-week sprints, shipping a working build every sprint. Release phase includes deployment, monitoring setup, and a handover session.
What ships with your Shopify Plus store
Every project includes these deliverables, no hidden extras.
You get everything you need to run and maintain the store yourself. All code, documentation, and infrastructure are handed over.
- Source code in your GitHub repository
- CI/CD pipeline via GitHub Actions
- Custom Shopify theme (Liquid + React)
- Hydrogen frontend (if headless)
- Oxygen deployment configuration
- Stripe and PayPal payment integration
- Sentry error tracking and Datadog monitoring
- Shopify Plus checkout extensibility overrides
- SEO metadata structure with JSON-LD
- Admin documentation and training video
