Refund
A refund is giving a customer their money back after they paid.
In a simple example
A cake arrives broken, so you refund the customer 8 dinars and the payment returns to their card.
Why it matters to you
A clear and fair refund rule makes people trust you enough to buy for the first time.
Do not confuse with
A refund returns the money you took. A chargeback is a refund forced by the customer's bank.
