Hey there, @Jeff-ocens. 

Thanks for reaching back out on this thread. 

The payment method field doesn't show on the invoice itself in my test account either. However, it does show when you go to record the invoice payment. 

Also, if you'd like it to still show on the invoice itself, you can add a custom field to it if you have QuickBooks Advanced version of Online. 

If you have any other questions, don't hesitate to ask. I'm only a post away if you need me. Take care!
