One of the burning trends in logistics these days is 3PL (third-party logistics) when inventory, warehousing, and fulfillment are outsourced to some third-party vendors. They usually use the following 3 types of WMS systems: integrated ERP, supply-chain modules, and standalone WMS. Some of the leading ready-to-use systems are NetSuite WMS, Fishbowl Inventory, Softeon, and HighJump. Even though they are represented as out-of-the-box WMS solutions, it is necessary to select the business specialization inherent in each system: wholesale, manufacturing, 3PL, e-commerce, and the like.
