I have made that suggestion multiple times. I don’t want to add it to every invoice. I want to send an invoice with Labor, materials, and taxes to a customer. If and only if they open the email and choose to pay with a card, at that point, QB will say “Younwill be charged a 3.5% convenience fee. Do you wish to proceed?” For now, I’ve created a line item and have to manually enter the amounts. But worse, I have stayed in that line item to please remove this amount from your total of paying with check. It’s a bit bothersome for my customers and a bit embarrassing for such a reputable accounting program.
