Hi there, accounts-2upc-co.

Allowing the credit/debit card for payments as an option would be a great help to get way you want to handle the payments from your customers. 

However, we're unable to disable our PayPal account while allowing credit/debit in use. I see this isn't the feature or option you want to utilize within your QuickBooks company. We can send this suggestion to our Product Team. They will gather details about this, evaluate your idea to implement this option in the future. Go to the Gear icon> select Feedback.

GoCardless for QuickBooks has a plan name and its price. I'd recommend checking the chart below. 

If you have additional queries when collecting payments using this platform, I'd suggest contacting GoCardless Support. We can review their contact details under the App information section. We can also find the screenshot above in this article: GoCardless for QuickBooks. 

And, yes, there is another option. We can look for another supported application to get this done. We can visit QuickBooks Online App Store to search for a third-party application and integrate it with QuickBooks.

 Also, we can read through this link for additional details about managing sales and customers in QBO: Topics about your company's income and customers.
