Can you move away from Shopify later?

Yes, and it is a real project rather than an export. Products, customers and orders come out cleanly; theme, apps and URL structure do not.

The reasoning

The part that hurts is the URL structure, because links and search rankings are attached to it. Plan redirects before the move rather than after, or the traffic built over years is spent in a weekend.

What most people get wrong

The apps in the Shopify store are where the cost quietly grows. Six at twenty dollars a month is more than the plan.

Most Shopify performance problems are the theme and the images, not Shopify.

Shopify handles the parts that are genuinely hard and genuinely regulated: payments, taxes, order records. That is what the subscription is for.

How an app changes it

A mobile app sits on top of Shopify rather than replacing it — the catalogue syncs, and checkout stays Shopify’s.
