How do you keep Shopify costs under control?
Watch the app bill rather than the plan. The subscription is fixed and visible; the apps accumulate quietly and are the line that grows without a decision.
In more detail
A quarterly review with one question per app — what would break if this were removed — usually recovers a meaningful amount. Anything nobody can answer for is a monthly charge for a problem that has gone away.
What to do about it
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.
The mobile app angle
A mobile app sits on top of Shopify rather than replacing it — the catalogue syncs, and checkout stays Shopify’s.
