No two Shopify stores look the same on the back end, because so much depends on the theme and apps installed — what one store tracks as a metafield, another handles through a completely different app, and the "correct" way to fill a field often only makes sense once you've seen how the live theme actually displays it.
We pay particular attention to variant configuration, since a three-dimension variant set up with an incomplete combination matrix doesn't throw an error in Shopify — it just quietly shows fewer options than it should on the storefront, which is easy to miss until a customer mentions it.
Stores running Shopify Plus with custom checkout scripts or advanced metafield structures need that context confirmed upfront, since entry that works fine on standard Shopify can interact unexpectedly with Plus-specific customisations.
