How to add an Expense
On the Event Budget tab, click the Add Expense button to enter the Expense details. Only Name and Amount fields are required.
You can associate the Expense with a Vendor, set the Category, and add Attachments such as invoices.
Note that you do not need to have the Planned Budget set to add an Expense.
From here you can also add the Payment Status or split the Expense across different Teams.
