Enterprise Shopify development cost breakdown
We explain what drives cost for enterprise Shopify builds.
Custom Shopify Plus development starts at $100K for a standard storefront and app integrations. Complex headless builds with custom checkout and ERP connections run $200K to $350K. Every IRPR project includes a fixed price quote in week 2 of the Roadmap phase.
Cost factors include the number of custom apps, integrations with SAP or NetSuite, checkout customizations, migration from existing platforms like Magento, and compliance requirements like PCI-DSS and GDPR. We typically quote 8-12 weeks for the build phase.
How IRPR is different from generic Shopify agencies
Most Shopify agencies charge hourly and deliver late. We do it differently.
Generic dev shops use junior developers and waterfall timelines. They often underbid and then bill for scope creep. A typical hourly project can balloon 40% above the original estimate.
IRPR assigns only senior developers with 7+ years of experience. We use a fixed price, no-surprise model. The Roadmap phase defines every feature before coding starts.
- bills by the hour with no cap
- uses junior developers or outsourced teams
- delivers 4-8 weeks late on average
- no dedicated project manager
- code ownership unclear or shared
- scope creep adds 30-60% to the final bill
- fixed price quoted in week 2
- senior engineers only, US timezone overlap
- 12-week average delivery, 98% on-time
- dedicated PM with weekly updates
- full source code ownership at launch
- scope defined in Roadmap - no surprise charges
Our 5-phase process for enterprise Shopify development
We follow a structured process to control cost and timeline.
Every project starts with a 1-week kickoff where we align on goals, tech stack, and compliance needs. The Roadmap phase (week 2) produces a detailed spec plus a fixed price quote.
Then we build the product in 8-12 weeks with bi-weekly demos. The Release phase includes load testing, security audit, and deployment to Shopify Plus.

You get more than a store - you get a launch-ready platform.
Every IRPR build includes production-ready code, automated deployments, error monitoring, and a 30-day post-launch support period. No hidden extras.
