The value of a third-party fulfillment partner depends on the size of your business, the volume of orders you receive, and the costs of fulfilling orders in-house compared to a 3PL solution. For some ecommerce businesses, in-house order fulfillment is the more cost-effective or preferred choice. For others, the cost of 3PL fulfillment services and the operational bandwidth they gain by outsourcing fulfillment is the right choice for their business.
