When you use PTI to invoice out billable items from an AyaNova workorder into a Peachtree invoice, you could print a workorder report from AyaNova and physically provide the report along with the Peachtree invoice.
OR you could specify Descriptive Text to show on the Peachtree invoice - which is text from the AyaNova workorder that was billed out
Descriptive Text is set via the Tools -> Invoice descriptive text template menu option from the main PTI screen
You can set as much or as little descriptive text about the service workorder(s) to display in the Peachtree Notes part of an invoice.
You can use the pre-set defaults, and/or edit directly what you wish to display, and/or have no additional text display
