Hello pjo65.
Thank you for your question.
By now, the only multi currency capable plugin we support is WooCommerce Multilingual for WPML( you’ll need WPML installed).
When multi currency enabled, ATUM adds the purchase price for each currency you set (when setting manual prices for secondary currencies).
So, each product will have the default currency prices (the one set in WC settings), and you’ll be able to set the prices in other currencies (even the purchase price). You can see it at the image
Please, note that we didn’t include multi currency in PO (WC doesn’t either with its orders), so the prices that will appear in PO will be the default currency ones. Then you can only set the default purchase price from PO’s screen.
Anyway, if you set your WC store’s currency to euros (for example), it will be the default currency for all products, you can’t choose on currency for one product and another currency for other product.
Hope this helps,
José Andrés
