You can review the invoice history to check the final status of the invoices in Collaborati or to see if an invoice was successfully entered in the system. The Vendor Admin user can login to Collaborati and click on Invoice > Invoice History and search for the invoice number . The History only gives limited information but would show if the invoice is approved or rejected and also if it was uploaded successfully.
The invoice history will not show if the invoice was deleted.
The invoice history should be available for 3 years.
