In Version 2011 Intuit has added a new Payment Link on Invoices. If you use Merchant Services and email your invoices AND this is a nice add-on. BUT… if you don’t, it’s real irriating.
This is an advertisement for Intuit’s PaymentNetwork. These links can be removed ONLY by the QuickBooks Administrator in single user mode; by going to the Edit menu -> Preferences -> Payment Preference -> Company Preferences tab -> and making sure that BOTH the “Show payment link on emailed invoices” and “Show payment link on printed invoices” options are UNchecked
