Invoice Branding - Ability to map to specific currencies.
It would be great that it would be possible to set a default branding theme for a particular currency. This way the payment details added to a theme tailored for a Currency will match the invoice currency without manually having to set the correct theme in the invoice.

Hi Thomas, while you can't match a specific branding theme based on the currency of the invoice, you can set this at a Contact level.
If you generally invoice a contact in a particular currency this means that you set this in the Contacts record within their Sales defaults section - see more in Xero central

I tried to work around this current lack of functionality setup a lookup spreadsheet and zap ensuring accuracy when mapping to Xero fields, test runs OK but pulls no data and can't see why. I would like to suggest Xero makes it possible to automatically assign currency and branding theme based on country address and or zip/postcodes as requiring us to do this manually creates room for error and results in us being charged costly conversion fees. It's a long, not very intuitive display where we have to do this manually making it very easy to miss so even improving on that would help.
