Change VAT in purchases already created

Hi,

I have made a mistake and created my invoices for TFL with VAT, now i would like to change them all. Is there a way i can do it without entering each one of them individually?

You would need to go into each invoice and remove the VAT manually. The other option is to calculate the total VAT wrongly attributed and make a single adjustment on your VAT return.
