Deleted order/invoice

Im in a real crisis now. I have never used the invoice system in zen for my acountant so i have used the delet option sometimes just because of the restock product option. But now to make it easier for me i have started to use the system and programmed it to fit norwegian laws. Our requirements is to have the invoice no in a sequal. But the invoices i have deleted are gone... Tried to serach it but with no luck.

Can anybody help me with this issue? I guess the invoices are in the database somewhere, but this is out of my league.

Hi there
Sometimes deleted means just that DELETED. So they are gone. If you have been using a different system to invoice from you could reprocess then however you will not be able to re-use the old numbers sinxe ZC can olny only count up from the current invoice number. If what you are doing is for tax or other accounting stuff then it might be feasible to export to a spreadsheet all invoices and then to manually add the deleted ones to the spreadsheet.
