We are an architecture firm.  We have multiple engineers under our contracts. When a client decides to pay with a credit card, it ends up being a 6-10% hit to us because we cannot pass that fee downhill.  Some of our Billings are $70k and that is a huge loss for us.  Add the cc fee paid by customer and they will start using ACH.

btw:  Our state and local municipalities charge a convenience fee.  DMV, state licenses, etc. Our kids’ private school charges as well.  What makes them special?  Are they above the law?
