I too have held out for 8 years not accepting credit card due to the added fees, the last 4 years, I’ve accepted credit card to those who have asked but charge a convenience fee. What is convenient to them is very inconvenient to me. I need to update the current invoice and add the fee and resend. For a small business that spends little time in the office, this is becoming annoying, Especially now with the convenient option of allowing customers to pay by card through emailed link. Quickbooks needs to give us an option to automatically add convenience fee when customers choose to pay by card.
