The Transportation Management System (TMS) integrator market is composed of service providers that can help with the selection of TMS solutions as well as the configuration, integration, implementation and/or upgrade of transportation management applications. TMS integrators may also offer additional services, ranging from implementation of other supply chain execution (SCE) solutions, such as WMSs, to strategic consulting and, in some cases, even IT and business process outsourcing (BPO) services. SIs can make recommendations for process changes and help with vendor selection and implementing the tools.
