Two currencies

Two currencies

More and more I am finding that internattional payments' fees are unpredictable.

I would like, on my invoices that are in a foreign currency (eg. USD$ or EUR€) for there to be a GBP£ TOTAL display alongside the invoice's currency total.

This would make it easier them to pay me in GBP rather than make me subject to many Banking fees.

I have ZOHO ONE which does not have the MULTI-CURRENCY PER CONTACT option.
•  Is there another way to achieve these 2 Totals on my Invoice?
•  If not, can Multi Currency Per Contact be "Added On"?
