For customer without names I have a customer name set up as "cash sale" and use that as such. Therefore I have a list of invoices built up over the last year or two under that name however I now notice that "cash sale" is missing from the list of customers and also all invoices from that "customer" have disappeared too.
I have definately not been into the customers list and deleted any as I never go into that section. Any other reason how it could have disappeared and is it normal that if a customer has been deleted, then it would also delete all associated invoices with that customer?
I do have backups so is there any way it is possible that the customer and the previous invoices could be restored without affecting my current data?
