Marketplace fulfillment is when the platform you’re selling on handles your order Fulfillment process. This means they warehouse it, pick it, package it, ship it out, and take care of any returns. Some marketplaces, like Amazon, will even handle your customer service (FBA). All you have to do is send your products to the warehouse of the marketplace.
