OOli in Plymouth UKForum|Forum|4 years agoMay 9, 2022Adding a PO number to invoiceForum|Forum|4 years agoMay 9, 20221 reply1 viewI can't seem to add a PO number for some reason. Here are my options. Do I need to change the subscription or is there another way to add a PO number box. Custom item will not allow me to add either. Any help would be great.
