Virtual products

We distribute increasing numbers of, Virtual products. As a charity, most of these are given away or sold for £0.00 from our website. We still want to record who downloads what, to derive their interest in different parts of our service. And in future we may want to sell virtual products. SAGE has three fundamental stock types, “Stock”, “Service / Labour”, and, “Miscellaneous. Could a fourth type, Virtual product, be added? In the 21st Centuary I can&t believe we are the only organisation using SAGE and selling virtual products?
