I see, at the start you can select Multiple Orders at the same time and then click "Fulfill Orders"
When you need to add tracking in bulk you can use the following app to complete your requests: MassFulfill – Ecommerce Plugins for Online Stores – Shopify App Store
Hi @MarioKan , this may help too - we're developing a Shopify app called BeProfit. It basically helps you track your entire expenses and profits, including status of your orders' payment, fulfillment, shipping costs, COGS, profits and more - all in one intuitive dashboard. The app is free for now, you're more than welcome to give it a try.
Best of luck!
