SAN DIEGO, CA – May 12, 2009 – Trade Service announced today that Maxwell Systems, Inc. (King of Prussia, PA), a leading provider of construction business management software, has released Maxwell Systems™ Estimation Logistics™ 8.1 that integrates to Supplier Xchange™, Trade Service's latest Internet-based offering that allows contractors to request and receive customer-specific pricing, in real-time, from their preferred suppliers.

"Today, more than ever, contractors need better ways to control costs, increase productivity, and improve the bottom line," says Karl Rajotte, Director, Quality Assurance and User Documentation, Maxwell Systems. "By integrating Supplier Xchange with Estimation, we have another tool to help contractors further streamline the bidding and estimating process."

This new interface allows Maxwell Systems Estimation Logistics customers to send a list of materials from their estimate directly to Supplier Xchange, where it is matched against their selected supplier's inventory price file. Then, within seconds, their specific pricing is returned to them for direct and immediate import into the bid.

Currently, over 2,300 distributor locations support Supplier Xchange with more being added every day. "Supplier Xchange was developed in response to an overwhelming demand from contractors who needed a way to acquire a more realistic level of pricing for use at the critical time of bid submittal," said Tod Moore, Vice President of Sales & Marketing for Trade Service. "Now that Maxwell Systems Estimation software supports this dynamic new capability, a new community of electrical contractors is able to more successfully compete in this tough economy and potentially win more of the jobs that they bid on."

Supplier Xchange is a component of TRA-SER® SX, Trade Service's new, fully Internet-based electronic catalog and pricing service, and is provided at no additional cost to all TRA-SER subscribers as well as to all suppliers who subscribe to Trade Service's electronic pricing services.
