The Messages can be entered to appear on the bottom of the Invoices, Packing Slips and Quotes, as below:
These are set up under Admin / Defaults / Manage Customer Defaults - Messages tab, and can be added to or edited at any time.
The Payment Message, which contains the bank account details below
Is also set up under Admin / Defaults / Manage Customer Defaults
But this message is designed to appear on all Invoices and Statements.
Please see Statement Messages for separate instructions.
If the messages do not appear in any of these locations, contact your Partner or Infusion Support who will look at the customised layout.
