It would be great to have some settings where you only allow one entry line for one specific product on the quote. This means duplicates won't occur for that specific product and the user will ensure to put the correct quantity on the one order entry for the product.
this will be amazing as errors wont occur when placing orders and will be more efficient in providing orders to dispatch which if happens then causes delays and errors with accounts
This would ensure more efficiencies when picking stock as this means one trip to respective area and no confusion over amount picked
