Invoices are a lie, they add extra fees after the fact.

This company's billing is a ****. They charge a 'cash discount' on the day and then hound you for months and send debt collectors after you because you didn't pay the full amount, apparently, and there were 'additional fees' after the fact?! You will never have to deal with this at Ampath, who don't try to claim back their cash discount, I can tell you. Pathcare lie about the charges on the day, and then make up fees to add to your invoice. I will never use them again.
