How do I set up credit card payments for my customers ?? I got the paper print part but I want them to have the option to send a payment thru credit card

You've come to the right place, @aaamagicmaintena.

Let me lend you a hand in taking care of this. 

You’ll have to turn on the online payments feature to set up credit card payments for your customers. This way, they can pay invoices through this method. All they have to do is follow the link in the email.

Here are several sections to complete the process:

1. Sign up or connect an existing QuickBooks Payments account.
2. Process the payments in QuickBooks Online.
3. Learn about deposit times for customer payments.

Please check this article to completely guide through the steps: Take and process payments in QuickBooks Online.

After credit card processing is activated, you can automatically process credit cards using recurring sales receipts. For steps to do this, see Creating recurring transactions using the QuickBooks Merchant Service.

Keep me posted if you have any other questions. I'll be happy to help you out. Wishing you and your business success.
