How can I change the VAT part of invoices?
To have an invoice showing e.g. the Australia specific GST instead of VAT, go into System > Settings > System Customization > HTML Templates. Add a template, call it 'Invoice' and select 'Invoice Template'. Click on 'Edit Content' next to the newly-created invoice template. Scroll down to line 223 which should say
<p>V.A.T @ :</p>. Replace the 'V.A.T' with e.g. 'GST' and then save the changes.
If you correctly set up your tax settings in System > Settings > Accounting Settings > Tax Setups, the changes you made to the invoice template will show up in invoices from now on.
