Invoice Message
In the Invoices form you can have a custom message appear on the printed Invoice. This is a good way to enter a specific message about the selected Invoice. There will be one of two slightly different buttons displayed on the Invoice form depending if a message exists or not.
This button will appear if there are no messages entered for the selected customer invoice. Clicking this button will open the Invoice Message form, which will allow you to enter a message for the selected customer invoice. When you are done entering a message, click on the X button at the right hand corner to close the form and return to the customer invoice form.
If this button is showing in place of the normal message button then it means there are existing messages for the current customer invoice. Clicking this button will open the Invoice Message form displaying the previously entered message for the selected customer invoice. When you are done editing or viewing that message, click on the X button at the right hand corner to close the form and to return to the customer invoice form.
