Keeping the Notion inventory database in step with the live Etsy shop was a manual chore, and Etsy only shows current state — past prices, stock levels, and listing lifecycles are lost unless recorded. The sync now runs against the live shop with live Notion writes, targeting zero manual inventory edits per week. In constant real use.
