Orders that you have marked as "Fraudulent", "Cancelled," or "Returned" are not charged transaction revenue share.

You can mark a returned, duplicate, or fraudulent order as "Returned", "Cancelled," or "Fraudulent", and that order will not be counted as part of your revenue-share total.

You'll have 90 days after an order comes in to mark it for this purpose. Billing for revenue-share occurs on a monthly basis, so if you've already been billed for the revenue-share that includes orders you've since marked as returned, cancelled, or fraudulent, a credit will be applied to your the next month's billing.
