No redirect map. WooCommerce URLs (/product/slug/, /shop/, /product-category/) don't match Shopify's (/products/handle, /collections/handle). A CSV import skips redirects and organic traffic drops hard in week one. Worth knowing before you scope: Shopify will not let you create a redirect from certain reserved paths, and /shop is one of them. That is a real trap for a Woo store whose shop page lives there, and it gets tested on a dev store before I quote, not after launch.
02 ◆
Variable products mapped wrong. Woo's variable + attribute model maps to Shopify's variant model badly via automated tools — SKUs duplicate, inventory desyncs, prices land wrong. Shopify now allows 2,048 variants per product, but still only 3 options. If your product has four or five attributes, one of them has to become something else, and no tool makes that call for you.
03 ◆
Reviews lost. WooCommerce reviews (or Judge.me/YITH on Woo) don't carry over unless exported and re-imported. Years of social proof vanish, and with them the star ratings in your search results, which costs you clicks on every product page that had them.
04 ◆
Subscriptions broken. WooCommerce Subscriptions has no native Shopify equivalent — it needs ReCharge or Bold, and the active subscriber payment tokens have to be migrated carefully or churn spikes. This is the item I scope first, because it is the one that can lose you revenue outright.

Customer passwords handled the old way. WordPress hashes aren't Shopify hashes, so passwords never transfer. The old answer was a mass force-reset at launch, which locks people out in your first week. Shopify's passwordless customer accounts remove the problem: email, six-digit code, in. I launch on those by default and there is no reset wave.
