If you need to keep track of many non-financial details related to your
business, you can use the QuickBooks To Do list to keep track of these. You can
use the To Do list to remind yourself of things such as:
Calling a customer to pick up a special order.
Calling a vendor to check the status of a shipment.
Sending out sales catalogs.
To add "to do" notes, go to the Company menu and click To Do List.
