If you are collecting some, or all, of your registrants' fees "offline" (not through online credit card processing), you will want to track when you actually receive a registrant's payment. To do this, log into the admin side of Treefrog, and select "Manage Event" on your event. Click on "Registration Manager" in the gray section on the left, and then click the "Search" button to show all registrants for the event. Find the registrant, whose record you'd like to change and then click the green "Transaction" icon on the far right column. You will see all transactions for this particular registrant in this event. Put your cursor over the dollar sign icon in the far right column. By clicking the icon, you can toggle between "Paid" and "Unpaid". Your selection will be reflected in the Revenue report, and also the Event Dashboard.
