Hello Paul - thank you very much for your suggestion - I am not sure that it helps though? Might be because I am complicated!
1) Currently I can enter Amazon as a supplier, which then automatically populates 'item' field and VAT fields. But I have to make a manual entry in the 'description' field. (which is what is unnecessary for me).
2) If I toggle on stock/product lists, after entering Amazon as the supplier, I am then asked to choose an item from a drop down list. So I set up Amazon as a product code with cost code and VAT settings
3) The Cost Code and VAT settings for the Item then appear to override those of the Supplier. Amazon has reverse VAT treatment, but I cant find an option for that against an Item, so VAT is not treated correctly?
best wishes
Graeme
