"Paid By" Data Element for Invoices
Whether using a report or working within a paid/refunded/closed invoice, an Admin should be able to view the user that placed the invoice in an "final" status.
Example: manually paying the invoice
A timestamp of ‘who’ and ‘when’ paid an invoice can be viewed within the invoice itself. To the right of ‘Invoice Status’ clicking on a magnifying glass icon will reveal the details you need!
