Welcome to the Community, Kazsnafix.
You've reached the right place for assistance with QuickBooks. I'm happy to provide some info about reminders in your Online account.
At this time there isn't a reminder feature in QuickBooks Online. I can certainly see how this would be a beneficial tool to have. You may consider submitting feedback to the Product Development Team for review. This can be done directly through your QuickBooks Online account by clicking the Gear icon in the top right corner, then select Feedback. This is the best way to voice your suggestions as many product updates and feature releases come directly from these user entries.
In the meantime, I recommend checking out available third-party apps for task management. These apps integrate directly with your QBO account to help make your job a little easier. You can view them by clicking the Apps tab in the left navigation panel of your account.
Please don't hesitate to drop a comment below if you have any other questions. I'll be here to help in any way that I can.
