Hi All,

I need to display the sub total amount in multiple currencies.

What options do I have?

2

if I add change rate of the additional currency as custom value to the invoice can I use some math formula in the invoice design?

3

Maybe add a custom invoice field and then use a custom design to show the field new the current value.

Just a suggestion, not sure how it will work out…

I have to display the rate and the calculated value also and I already used one custom field for a required extra date.

"
Shipping Date: 2017-12-31
Invoice Date: 2018-01-01
Payment Due: 2018-01-15

Subtotal 120 EURO (106.672 GBP)
Rate: 1 GBP = 1.12495 EURO

In that case I’m not sure
