RedPrairie Corp. on Friday unveiled an upgrade of its warehouse-management system that includes customs, labor management, and billing modules.

Dispatcher-WMS 8.4 also includes additional features, such as product substitution, container replenishment, and staging of pallets, officials with the Waukesha, Wis., company said.

The upgraded customs module stems from RedPrairie's acquisition in October of Online Duty and Logistics, which sold the DutyMaster software suite for excise and customs warehousing.

The AcitivityBilling module enables third-party logistics and public-warehousing providersto accurately track activity for multiple clients within a single warehouse and manage complex, invoicing contracts on a client-by-client basis.

Labor Management calculates the estimated time that a task should take before that task is started. The calculated times take into account the routes that operators should follow, the time to access the locations, the nature of the materials handled, and other operational parameters.

Dispatcher-WMS 8.4 is available now, and is compatible with Borland's application server and IBM's WebSphere.
