3PL providers handle storage, fulfillment, and shipping operations for ecommerce businesses.
A third-party logistics (3PL) provider is an external company that manages your inventory storage, order fulfillment, and shipping processes. Many Amazon sellers use 3PLs to handle operations outside of Amazon.
3PL services are especially useful when you sell on multiple channels or need to store inventory before sending it to Amazon. They help you scale operations without managing your own warehouse.
