Dovel developed the Trip Cost Estimator (TCE) to help the Department of Defense (DoD) better manage travel costs and enable more effective financial planning. This service-based solution was the first ever Service-Oriented Architecture (SOA) implementation in the DoD. The service provides Defense employees with an easy process of planning future trips based on air, hotel, and car costs collected in “real-time” from multiple sources and on historical information retrieved from the Defense Travel System (DTS).

TCE interfaces with the primary Financial Management Systems for each of the 5 services within DoD.
