Good day, Katie Roe.

You can create a bill reminder, then set to remind before the due date. 

Let me guide you how:

1. Open the bill.
2. Click Memorize, then choose Add to my Reminders List.
3. Choose how often you want to be reminded, then enter the date in the Next Date field.
4. Click OK.

I've attached a screenshot for your reference.
