How do you set up the automatic billing that will automatically bill the customer with ACH information?

I know a way for you to receive your payments in QuickBooks Online (QBO), PatriciaW1. 

In QuickBooks Online (QBO), you have the option to create a recurring sales receipt to collect customer payments regularly or monthly. To do this, you'll need to enter your customer's bank information and then obtain authorization from your customer by printing an authorization paper and providing it to them for completion. Once you've received the completed form, you can update your template by accessing the Action dropdown within the Recurring Transactions window. This will allow you to save your customer's payment information for future recurring sales receipts.

Kindly follow these steps: 

Step 1: Set up and use a recurring sales receipt

1. Go to the Gear icon in the upper right corner. 
2. Under the Lists column, choose Recurring Transaction.  
3. Click New.

5. Fill out the necessary info within your form. 
6. Within the Payment method dropdown, you can choose either Check or QuickBooks Payment - Bank.
