Invoices have a status set to indicate their current position in the workflow.
After you have selected the tasks to be invoiced and you submit the invoice on the Ready To Invoice page, its status is set to Submitted.
Once Lingo24 has paid an invoice via bank transfer or other means, the status is set to Paid.
Occasionally Lingo24 will need to cancel an invoice. If this ever happens, it will only be done after discussion with you. In these cases, the status is set to Cancelled, after which Lingo24 may ask you to create another invoice for the Tasks that were on the cancelled invoice.
