Improved: Import of purchase orders in invoices

Certainly you have to match invoices with the values of purchase orders. But what about negative positions in an order?

Orders can be imported into invoices and compared with the values of the individual items. Any remaining amounts will remain on the order. So far, this could only be done with positive order items. Discounts, agency fees or similar however, can lead to negative positions in an order. These can now also be imported and adjusted in PROAD.
