Once you install, you'll get a set of instructions that will help you add order edit/cancel and re-ordering links to your order confirmation email and customer account page. Setup should take about 10 minutes, and then your customers will be able to easily edit, cancel and reorder their orders.
How is refunding handled?
When your customer cancels an order, we automatically refund the order.
What happens when I've already shipped or fulfilled the order?
Customers will not be able to edit/cancel orders once they are marked as fulfilled or any fulfillment has been created. You can also set fulfillment rules such as a time limit to allow order editing/canceling.
