When you buy an item at a store with a bank transfer or credit card, you are promising that the money is available in your account. The store doesn't receive the money for up to 3 banking days later.
Sending a bank transfer deposit to Maersk International Transports & Logistics works exactly the same way. To ensure payment, Maersk International Transports & Logistics waits until the money is deposited into our trust account, which is then considered "good funds." This takes longer, but gives Buyers and Sellers an extra level of security.
