Q: What is the Third-party Fulfillment Service?

A: Third-party fulfillment providers do more. They do kitting/assembly, value-added services, and give you more shipping method to choose.
One of the advantages of drop ship is you don’t need to handle the packages, which reduces a lot of hassle. But this also makes the packing customization impossible. Third-party fulfillment providers can do a lot of work for the store owners before the packages are shipped, such as kitting, assembly, adding marketing inserts, because they receive products from multiple suppliers and process them together.
Third-party fulfillment providers can make more flexible shipping solutions for the store owners, because global shipping is what they do , they have more experiences than the suppliers.
