On Mercari, the payment process typically begins after the buyer confirms that they have received the item and are satisfied with their purchase. Once the buyer marks the item as received, Mercari releases the funds to the seller. This can usually take up to three business days, depending on the seller's chosen payment method. For instance, if a seller opts for direct deposit, the funds may appear in their bank account more quickly, while other methods may take longer to process. It is important to remember that Mercari provides sellers with a secure way to complete transactions, which includes this payment holding period to ensure that buyers receive their items as described. To find more specific information or updates regarding payment timing and processing, it is always beneficial to check the relevant sections on the Mercari website.
