The key differences are that internal fulfillment uses your own warehouse space and staff to handle order processing tasks, while 3PL outsourcers these operations to a specialized logistics company. Internal gives more control but requires more overhead, while 3PL leverages expertise and infrastructure at an additional cost.
Doing fulfillment internally allows full control over warehouse layout and inventory management processes. You can also easily offer custom services like gift wrapping. However, you need suitable warehouse space and staff to handle increasing order volumes.
3PL providers have extensive warehouse networks that allow placing inventory closer to customers for faster delivery times. They also handle all fulfillment tasks so you avoid many overhead costs. But fees cut into margins and you lose some visibility.
Key factors to weigh include cost structure, expected order volume growth, warehouse locations, need for custom services, inventory security, delivery speed and reliability, order tracking visibility, and level of customer service.
Internal fulfillment can make more sense when you have special product needs or custom services, lower and more predictable order volumes, and enough resources to handle operational tasks cost effectively.
Using 3PL fulfillment can be better for ecommerce businesses with high or rapidly scaling order volumes. Outsourcing can also help if you sell internationally or lack resources to handle fulfillment operational complexity effectively.
If internal costs are growing unchecked or order volumes exceed capacity, shifting to 3PL can provide more stability. However, if 3PL fees are too high or you want more control, bringing fulfillment back in-house can be better aligned.
