allow invoices or sales orders to be moved to a category called 'ready for shipment'. as soon as an order is paid or simply ready for shipment, we 'move it into this new category and than our logistics manager can do into that window as he sees all these orders are now ready for shipment, and he go ahead and schedule those shipments to go to our client. after that he can mark as shipped/delivered or partially shipped/delivered. that way we can always keep track of our orders status from beginning to end without having to dig into old printed papers.
