Invoice customization

Hello everyone,

I requesting some hand holding on changing the invoice template please.

In certain UK industries the tax (VAT) isn’t actually billed to the client but should still be on the invoice.

I am trying to figure out how to add a row below ‘Balance’ which says VAT and also calculates 20% of the balance value. However, I do not want it to add it to the balance as the client does not pay this to me.

Could anyone help? I haven’t got a clue. It would be much much appreciated.
