Shopify Plus Project EstimationProject Estimation
Get a fixed price for your Shopify Plus build in 2 weeks. No guesswork, no hidden fees.
IRPR builds Shopify Plus stores with custom Liquid themes, headless Hydrogen frontends, and integrated APIs. We estimate every project in a 2-week Roadmap phase before quoting a fixed price.
Most Shopify Plus projects ship in 8-12 weeks and cost between $80,000 and $250,000. Every build is PCI-DSS Level 1 compliant and includes full source code ownership.
We work with ecommerce brands migrating from Magento or WooCommerce, high-growth DTC companies needing custom checkouts, enterprise retailers launching B2B stores, and subscription brands requiring recurring billing logic.

Why accurate estimation matters for Shopify Plus projects
We have shipped 200+ Shopify Plus projects with a 98% on-time rate.
Every Shopify Plus project is different. A headless storefront with custom checkout costs more than a theme-based store. Our estimation process maps every feature to a line-item cost before we start building.
We use a 2-week Roadmap phase to define the tech stack (Liquid, Hydrogen, Node.js, PostgreSQL), integrations (ERP, CRM, payment gateways), and compliance requirements (PCI-DSS, GDPR). You get a fixed price and a 12-week timeline.
How we estimate vs. typical agencies
Our estimation process eliminates surprises. You get a fixed price before we write a single line of code.
Most agencies give you a ballpark range and bill hourly. Scope creep eats your budget. We do the opposite.
After the Roadmap phase, you receive a fixed-price contract. No hourly billing, no surprise invoices, no hidden fees.
- Vague estimates with no line items
- Hourly billing that encourages delays
- No roadmap to validate scope
- Scope creep without change orders
- No compliance documentation
- You don't own the source code
- Fixed price after 2-week Roadmap
- No hourly billing – ever
- Detailed scope with tech stack decisions
- Change requests priced upfront
- PCI-DSS Level 1 compliance built in
- Full source code ownership from day one
