• Track inventory quantity on hand.

4. Press Save and then Done.

After that, we can start setting up the items you track quantities of. I'll show you how.

1. On the left panel, select Sales and then Products & services.
2. Tap the New button, then choose Inventory.
3. Fill out the required details.
