Joining in on this thread to assist you on how to access the authorization form for your customers so you can receive funds from them electronically through QuickBooks Payments.

When paying bills to your vendors, there's no authorization form required since you can use Intuit's direct deposit service. You'll only need one from customers when deducting funds from their accounts. They must fill out this form in order to grant businesses to charge their bank or credit card accounts for payments.

Here's how to access the authorization form:

1. Sign in to your Merchant Services account.
2. Select Create a Recurring Payment under the Recurring Payments section.
3. Scroll down to the Payment Method section and click the signed authorization hyperlink to access the authorization form.
4. Download or print the authorization form and send it to your customer.
   

Additionally, you can process a refund in QuickBooks Payments within six months from the date of the sales if you need to return your customer's money.
