I just helped a friend input their purchases on another cloud based software (Pandle) for inputs under their travel entry it defaulted to 0% VAT/NA. It would be really helpful if there was a function added to Purchase codes to allow you to set a default VAT rate. Alternatively this could be set for a supplier eg so that Train Companies could be set to a default 0 VAT. An option to change it when when recording the purchase could be retained.
