How can i achieve this and keep a check on unbilled costs through the unbilled costs by job report. It seems that if I use an item in the billable time/costs window and then edit the amount on the invoice so that not all of the items are billed on one invoice the remaining items do not appear if I try to invoice for remaining items. E.g if i buy in 1000 t shirts and want to bill the customer for 250 a time how can i do it and let QB keep a check on the stock we hold and what still needs billing? I am using pro 2002
TIA
Jon
