When shall I use Settled when refunding customers?
Check **Settled** if you've manually processed the refund with the payment provider and want to record it in the system. A green dot will appear which indicates that a refund of the returned product is done.
When creating a regular refund, do not check Settled, as it will not be sent to the payment provider.
