WooCommerce Multi Currency
WooCommerce multi-currency allows you to choose the currency of the order. You can choose one or several currencies of the order. Important notice. Please note that to display the payment gateway on the checkout page, this payment gateway must support the default currency.
Example: if the default currency is South African Rand ZAR, then you cannot enable PayPal on the checkout page. Because PayPal does not support ZAR, even if you used multicurrency to change ZAR to USD at the input.
