Let me ease your confusion, NB34.

There are two billing options for QuickBooks Online:

• Monthly payment
• Yearly payment

There isn't an annual payment on top of the monthly fee. It's a good thing that you didn't provide your credit card information. 

You also have the option to switch to annual or monthly billing.

Feel free to let us know if you have other questions. We'll get back to you as soon as we can. Keep safe!
