Shopify's built-in reports will tell you a sale happened. They won't tell you the TikTok ad someone saw four days before they bought, or the abandoned cart email that finally got them to check out. That's the gap ecommerce attribution tools shopify brands rely on are built to close: connecting a sale in your Shopify admin back to the actual marketing touch (or touches) that caused it, instead of just crediting whatever channel happened to get the last click.
