I have been sending invoices for years to my clients with a pay here button that they could use to send a payment. Without warning, the process suddenly stopped working 1 week before the Oct 15 tax filing deadline.  It is now Oct 20 and after 2.5 hours on the phone with QB support, hours of online research, I still do not have an answer.   I am very disappointed with the problems with the software and the inability to find solutions.  The program is getting worse not better.
