Thank you for reaching out to the Community, Chris1929. 

I've got some steps on how to change your payment method to direct debit in QuickBooks Online Accountant. Before you start, know that only an admin can update payment info for your account. Also, you'll need to update payment info in QuickBooks Online using a web browser. You won't be able to update payment information from the mobile app.

Follow these steps: 

1. Go to the Gear icon located in the upper left corner. 
2. Under the Your Company column, click Subscriptions & Billing. 
3. In the Payment Information section, select Edit ✎.
4.  Under Payment information, choose Direct Debit.
5. Fill out the necessary billing information.
6. Tick the checkbox if you are the only person required to authorize Direct Debit, or have submitted the Dual Signature Form. 
7. Once you have read and understood the Direct Debit Guarantee, tick the checkbox.
