Hi there,lindaherman.
We can set a Reminder schedule when creating a recurring bill in QuickBooks Online (QBO). This way, you'll be reminded to create a bill using the template and change the amount every month. Also, if you want the auto payment to the vendor you can consider this option: Pay a vendor.
You can refer to this link for more details about the recurring transaction in QuickBooks: How to set up a recurring bill.
Get back to us if you need more help with recurring payments. We're always here to lend you a helping hand. Take care!
