The VAT 103 is a registration certificate. In other words the registered party is obliged to charge VAT and can claim input credits against that charged. It does not mention zero rating at all. Regardless anyway of what his 103 says, you as a vendor are obliged to charge VAT.
Hi Clive - I don't agree with you on this as many of our customers have section 7 of the VAT103 certificate stating "Goods used for agricultural, pastoral or other farming purposes may be supplied to you at the zero rate in terms of the provisions of Section 11(1)(G) of the act."
