Invoices
“Open” is when an invoice is created, but when the payment is pending
“Void” is when an invoice is denied/deleted.
“Paid” is when an invoice has been paid by your employer.
“Processing” is when an upcoming payment is in progress.
"Approved or Auto-Approved (for Fixed Rate Invoices)" is when an invoice has been reviewed and accepted for payment by your employer. Note that payment has not yet been initiated at this stage — the invoice status will update to "Paid" once the payment is processed.
"Due" is when an invoice is available for payment.
"Overdue" for an invoice is when it's past due date.
