When creating an invoice, if the invoice date is later changed, it would be helpful to have an option so that the due date automatically changes with it to reflect the payment terms. e.g. if an invoice was dated 01/01/2022 and the payment terms were 30 days the due date would be 31/01/2022. If the invoice date was changed to 05/01/2022 it would be good for the due date to move to 04/02/2022 without having to change it manually. This would reduce the chances of making a mistake and having the due date wrong and make credit control better.
