Invoices must be closed for items to show as "Paid". Fund debits linked to an invoice are only marked as paid when the invoice is closed. Once all the line items and invoice charges have been added the invoice must be closed.
Close Invoice
If your invoice contains proratable charges, click Prorate.
Click Close.
Closed By — This is set to the logged in staff user who performs the Close action.
A "Paid" label appears along the bottom of each line item in the PO display when every non-cancelled copy on the line item has been invoiced.
Invoices can be re-opened at a later date if adjustments are required. See Re-Open an Invoice. If an invoice is reopened the Close date and Closed By fields are cleared.
