ClearSale recommends pre-reservation. In an ideal scenario, the order amount is reserved in the payment means when an order is received, thereby avoiding losing the purchase due to lack of credit. In the meantime, the order will be analyzed for risk.
As soon as ClearSale issues an approve/decline decision, the merchant may opt to complete the pre-reserve or cancel it. If the order is turned down, the reserve can be cancelled. This avoids unnecessary losses with the card operator. If the order is approved, the reserve is released and the order is safely delivered to the customer.
However, this is only our recommendation. We can handle several different scenarios, depending on what is best for your business.
