Step 1. Go to your Shopify Admin → Settings → Locations.
Step 2. Click on the location you want (e.g., Warehouse, Store, etc.).
Step 3. Look at the URL in your browser.
Example: https://admin.shopify.com/store/yourstore/settings/locations/108285493544
The number at the end (108285493544) is the location ID.
You’ll use this ID in the Net Terms under the Pickup configuration of the Wholesale All In One app.
