Thank you for the follow-up, @CaptainEon.

Allow me to help add some details about the PayPal payment. 

You're right, you can see this payment option on normal invoices. However, this isn't available in recurring transactions. 

As a workaround, you can create a recurring estimate instead. This way, you can manually send the invoice and select the PayPal payment option. 

For other references you can use in the future, you can visit our help site: Manage Customers and Income for QuickBooks Online.

Let me know if you have other questions about recurring transactions. I'll be here to help.
