Shopify Plus Agency in the USA: What to Check Before You Migrate

Migrating to Shopify Plus is a materially bigger decision than a standard Shopify build, both in cost and in the complexity of what a Shopify Plus agency in the USA needs to get right during the transition.

Ask about experience with your specific scale of migration

Shopify Plus is typically chosen by businesses with meaningful order volume, existing custom logic, or complex B2B and wholesale needs. Ask a prospective Shopify Plus agency for a specific migration of similar scale and complexity to yours, not just any Shopify Plus client.

Ask how they handle checkout customisation

Shopify Plus’s scripted checkout is one of its main advantages over standard Shopify, and a genuinely experienced Shopify Plus agency should speak specifically and confidently about what they have built there before, rather than describing it only in general terms from a sales page.

Plan for the migration weekend itself

Ask exactly how a Shopify Plus agency plans to handle the cutover: expected downtime, a rollback plan if something goes wrong, and how existing SEO rankings and URLs will be preserved through the move. A vague answer here is a genuine warning sign. Our ecommerce and Shopify development team treats this migration planning as a distinct, carefully scoped phase of every Shopify Plus project.
