How do I remove credit card payment option on all invoices?

I can see that you want to remove the credit card payment option for your invoices, isa41-10.

There's full flexibility in selecting how you want to be paid by your customers that suits how your business operates. Allow me to give you the steps on how you can add or remove payment methods in your account.

1. Go to the Gear icon and select Account and Settings.
2. Proceed to the Sales tab, click the Pencil icon from the Invoice Payments section.
3. Under the Payment options, uncheck the Accept Credit Cards. If you want to accept ACH payments, keep the Accept ACH marked check. If not, you can also remove the check from the box.
4. Click Save and select Done.

Just in case you have more questions with regard to receiving customer payments, I would also like to share this article with you: QuickBooks Payments FAQ.

It provides links to topics such as enabling/disabling payment methods, customizing the payment experience for customers, transaction fees, and deposit timelines.
