How Much Does Shopify Plus Development Cost: The Numbers
Real projects have real price tags. Here is what IRPR's actual builds cost.
IRPR has shipped over 200 Shopify Plus projects. Our average build runs 12 weeks and costs between $80K and $250K. That includes a custom theme, checkout customizations, integrations with apps like Klaviyo and Gorgias, and full PCI-DSS compliance.
Larger projects like headless storefronts with custom backends can reach $400K. We break every project into a Roadmap phase (week 2) that nails down exact features and price. No surprises.
Generic Dev Shop vs IRPR: The Real Difference
Not all agencies build the same way. Here is how we differ.
Most Shopify Plus agencies charge hourly and pad hours. They use pre-built themes and charge you for customization that should come standard. You end up paying $200K for what could have been $120K fixed.
IRPR gives you a fixed price after the 2-week Roadmap. We write clean, documented code in your repo from day one. Our senior engineers (not junior devs) handle your project end-to-end.
- Hourly billing with no cap
- Uses off-the-shelf themes
- Junior developers assigned
- No performance guarantee
- Code not documented
- You don't own the code
- Fixed price after Roadmap
- Custom theme built for your brand
- Senior engineers only
- 99.9% uptime SLA
- Fully documented code
- Full code ownership
How We Build Your Shopify Plus Store in 4 Phases
Each phase has clear deliverables and checkpoints.
We start with a 2-week Roadmap where we map out every feature, integration, and price. You get a detailed document with wireframes and a fixed quote before we write a line of code.
In the Product phase we build your store in 8-10 weekly sprints. You see live demos every Friday. The Release phase includes load testing, QA, and deployment. We stay on retainer for 4 weeks after launch.
