QuickBooks reminds you of many tasks you need to perform in the program. This Reminders preferences in Edit > Preferences > Reminders has both My Preferences and Company tabs:
•    My Preferences tab gives you an option to open the reminder window when you open your company file. Skipping this option makes the reminder useless.
•    Company Preferences provides many options of the reminder list you want to appear in the Reminder window, such as, Cheques to Print, Bills to Pay, To Do Notes, etc. You can then select whether you like individual reminder to Show Summary, Show List, or Don’t Remind Me at all.
