It would be great to have some custom fields on the sales entry screen. This question comes up very regularly with clients who are importers/exporters and also with mechanics. They often have extra...
I'm not quite sure about the difference, but ideally (at least one, preferably more) field that can be give a custom name (so that all staff entering the invoice know what needs to go in there). Then there would be a corresponding field where they would type the information applicable to that invoice. I hope that is clearer?
