So im struggling to come up with a good enough answer as to how to handle this. I sell lots of second hand goods and i need the VAT to be calculated on profit per item rather than total item price.
One way of which i have found is to 0 rate invoices, have them pushed over to Xero and then altered by me to the correct amount. But im wondering if there is a better method of doing so ?
Any help will be great,
