As you know PayPal doesn’t cover all the world currencies. If this is your case, TheCartPress PayPal plugin supports Currency Conversion for your eCommerces.
You can create your ecommerces with your local currency and, at the moment of payment, convert order amount to one of the supported currencies.
When you are setting up your PayPal, fill the currency conversion options properly:
Using Google API
The plugin calculates the conversion using the google API.
Manual conversion
The administrator must enter the conversion rate manually.
