DEX/UCS is an acronym for Direct Exchange / Uniform Communication Standard. DEX is the two-way electronic exchange of information, at the time of delivery, between a vendor's hand-held computer and a store's inventory system.     It's currently used by a number of our customers who generate invoices but still need to enter the invoice detail into the retailer's computer system during the receiving process.   DEX/UCS benefits supply chain partners Supplier Reduces invoicing / sales ticket errors Avoids manual entry into DSD system reducing delivery labor hours Supplier and retailer benefits Reduces check-in time Reduces the labor and associated damage by stopping the delivery  unauthorized items at the point of delivery Retailer Capitalizes on the use of the DSD system by: Closing the loop for inventory management - product detail comes straight from the supplier's system upon delivery Administrative cost savings by ending manual keying of delivery invoices by store personnel For more information on electronic data interchange or the UCS/DEX standard, please contact: Uniform Code Council 1009 Lenox Drive, Suite 202 Lawrenceville, NJ  08648-2313 (609) 620-0200 or check out the UCC's Uniform Communication Standard and Direct Store Delivery Committee information.
