I'm wondering if it's possible to save or recover from the system all invoices that we have deleted as we would need them for accounting purposes since they follow invoice numbering.
I believe if there is a option to delete an invoice that there should be a "folder" where they will be saved as well, similar with cancelled invoices, paid ones, drafts etc. in the folder "Billing-Invoices-..."
Now we have an issue where an invoice has been deleted, it can't be found in the whmcs system any more/on the clients portal, but when a new invoice is created, for same or other client just after, the new invoice doesn't get a number of the deleted one but next one in line. And then we end up with missing invoice in the invoices lineup...
Hope you understand what I'm trying to explain.
