The invoice report lists all invoices for the current month, last month or a date range. If the invoice was to a Third Party, then the name of the party is listed alongside the patient's name. The report is in order of invoice number (and therefore date).
Schedule invoices are listed after those for individual patients.
Deletions are also included in brackets ( ) and are deducted off the total invoices for the period. As deletions for invoices are dated with the actual date they were deleted, it is possible for the Invoice Report to include the reversal for an invoice, but the actual billing might be in another period.
