I am about to start invoicing a customer for a service and goods on the same invoice. One will be an exempt service and one will be subject to standard rate vat.  Using the Sage system and selecting a customer it populates the default vat code for the customer and I cannot change this. Is there a means to do this fairly simply and still use the Sage invoice facility. We have until now produced manual invoices and then input them to sage which is easy to do.
