Invoice Editor MP - Notes Tab
This tabprovides an area where you may make notes about the invoice. These notes will not appear on the invoice. This area is often used for communication between different members of the team who are working on an invoice. In addition you can keep important notes related to how the invoice should be constructed or client specific notes that are important to your internal team.
You can reach this tab by opening an invoice from the Invoice Browser and selecting the Notes tab.
