We have to mark invoices as "Sent" to reduce our stock levels.

This leaves us with the dilemma of not knowing which invoices have not actually been sent.

Not all invoices need to be sent but for certain customers it's necessary, can you guys think of a way to track this ?

An ideal solution would be to have "Post" instead of "Save & Send", we could then have a report which show us all invoices not actually sent with check boxes to mark as "sent" if they don't really need to be !

Stock levels also need to have another option of tracking, such as receives & Invoices or receives & sales orders), very often we need to process the items, have them deducted from stock a long time before they're actually shipped!

Physical stock - receives & shipments are no good with this scenario.

Accounting stock - bills & invoices are no good if we receive the bill a long time after item receipt !
