In print invoices not add payment metode to invoice ,Where its problem?

Hello there. I'm here to ensure you'll get the assistance you need with QuickBooks.

Before anything else, are you referring to the payment method attached to the invoice? If so, the option will only show on the invoice page when you have a merchant services application.

If you don't currently have a merchant services application connected to your QuickBooks Online (QBO) account, it is recommended to search for a third-party tool that is most suitable for your business on our QuickBooks App Store.
 

Additionally, I will provide you with an article that you can use to gain knowledge on recording sales transactions in two different methods in QuickBooks: Record invoice payments in QuickBooks Online.
 

I am fully available to help you with any inquiries you may have with QuickBooks. You can count on me to provide prompt assistance.
