Questions merchants ask

Are Shopify SKUs required to be unique?

Shopify can contain duplicate SKUs, but many fulfillment, reporting, and marketplace workflows expect a stable unique identifier.

Will this app automatically change duplicate SKUs?

No. It requests read_products only and leaves every correction to an authorized merchant in Shopify Admin.
