Numerous clients have asked how they send a statement showing part exchanges to their clients. At present there is no way of showing the purchase value being deducted from the invoice value resulting in a net due value. A simple link between certain customers and suppliers would enable a statement showing the invoice value and purchase value would be great. Suggestions have been made to show a negative value in the invoice under a different sales code in order to overcome the problem however the VAT boxes would then be understated.
