How does Cash on Delivery work
Charge your shipments at the destination
Cash on Delivery is a shipping method that allows you to charge the shipment separated from the order total. To the client, instead of a zero shipping amount, it will be shown a message explaining that the shipment will be paid at the destination.
This is a new feature and to use it you may need to install a newer version of your theme or change a couple of lines in your current one. Checkout v2 works seamlessly with this new feature, with no new action required.
