What you get with QuickBooks inventory

If you click Yes

QuickBooks puts some additional choices on your Vendors and Reports menus. The new choices let you add inventory items to your Items list, track and create reports about your inventory items, and write purchase orders.

If you click No

Your Vendors and Reports menus will not have the additional choices. Answer No only if you don't need to track inventory AND you don't need to write and print purchase orders.

You can reverse your choice

To turn inventory tracking and purchase orders on (or off) later, choose QuickBooks > Preferences and click Inventory.
