Why not provide a more simple way to search for invoices, based on the actual date of the invoice? Because there's a 10 days difference between the date written on the invoice, and the date appearing in the Upwork transaction search. For example if I download an invoice that on Upwork appears to be on April 25th, I'll notice that the actual date written on the invoice is April 15th. Thank God my accountant told me about this, or else I would have never noticed.
For example, the last invoice that dates April will appear in the beginning of May in the Upwork search, and that doesn't make much sense to a freelancer. All we want is to do a search from the first day of a month, to the last day of that month, download the invoices and send them to the accountant. not spend an hour checking if we didn't miss any invoices
