One of the options is to make available to the designated recipient at no additional charge an amount appropriate to resolve the error. If there is no harm to the recipient due to the delayed receipt, I think that no remittance to the recipient is need to resolve the matter. However, if the recipient incurred damages due to the delay (a drop in the exchange rate, a penalty for a late rent payment, something else), a small payment might be called for. Arriving at what that amount is will be a challenge, I suppose.
Of course, a refund of the fee you charged to the Sender is also called for in this circumstance.
