This thread is a couple years old and charging a convenience fee has become much more common now for all business types (not just government or utilities).  I don't know why a timeline isn't known...the ability to charge this fee has been in the works for 5-10 years and with the legal challenges solved over 3 years ago it is well known and used across many industries.  Like many people, we have invoices that make taking credit cards over $10,000 not practical unless they pay a fee.  The crappy solutions QuickBooks is offering here are not practical to implement since most people don't know how they will pay until after getting the invoice. Please prioritized and get this done now!
