Custom Platform to Shopify Migration

Move from a custom or legacy ecommerce platform to Shopify with a migration plan built specifically around your business.

Untangle the old system. Build the right one next.

Custom ecommerce platforms rarely follow a standard migration path. Data models, checkout logic, integrations, customer accounts and operational workflows are often unique to the business, which means the move to Shopify starts with understanding how the current system actually works.

Alleyoop maps the existing platform from storefront to operations before designing the Shopify architecture that will replace it. We plan data migration, custom functionality, integrations, storefront development, SEO, testing and launch as one connected project. The result is a Shopify or Shopify Plus store that preserves what the business needs while removing the complexity it no longer does.
