(SPSC) and Accellos, Breakthrough Supply Chain Solution for Microsoft Dynamics GP Market

Market Leaders Enable Automated Access to Largest Retail Enterprise Cloud Marketplace

MINNEAPOLIS and COLORADO SPRINGS, Colo., Sept. 17, 2013  — SPS Commerce, Inc. (Nasdaq:SPSC), a leader in enterprise retail cloud services, and Accellos, a leading provider of supply chain execution software solutions, today announced that they have partnered to deliver a fully integrated, turnkey supply chain management solution for the Microsoft Dynamics® GP market. The breakthrough enterprise cloud service changes the competitive landscape, enabling suppliers to seamlessly connect with more than 50,000 supply chain partners including retailers, distributors, vendors and logistics providers through a single connection from their Microsoft Dynamics® GP system to SPS’s Universal Network.

Driving Omni-Channel Efficiency

In a marketplace where e-commerce is dictating the tempo of change, retailers and suppliers require highly nimble and adaptable supply chain capabilities to respond instantly to changes in consumer demand and delivery preferences. Accellos and SPS Commerce bring these essential capabilities to the Microsoft Dynamics® GP community.

“SOG needed to integrate every trading partner in our supply chain with our Microsoft Dynamics® GP system to support our substantial growth,” said Nando Zucchi, Vice President of Sales & Marketing, SOG Specialty Knives & Tools. “With SPS and Accellos, we seamlessly automated our trading relationships with major drop-ship and traditional retailers including Amazon.com, Costco.com, Dick’s Sporting Goods, Wal-Mart and others within a few short weeks. This holiday season we will automate 1,750 transactions each week, saving our staff more than 60 hours of data entry every week. We are delighted by the solution and expertise provided by SPS and Accellos.”

Nimble Supply Chains are Connected

The enterprise cloud service for Microsoft Dynamics® GP was developed by Accellos using the SPS Commerce Retail Standard XML (RSX), a comprehensive data interchange format that enables frictionless expansion and growth of trading partner relationships. RSX works with all data formats (including EDI, XML, flat file and others), allowing suppliers to automatically connect with a greater percentage of their supply chain community. The cloud-based solution connects an organization’s Microsoft Dynamics® GP system to the SPS Universal Network, not only automating supply chain relationships with more than 50,000 trading partners worldwide with a single integration, but also providing automated connections to any future trading partners.

“The SPS Universal Network offers our customers access to the leading retail enterprise cloud service and dramatically expands the reach and power of their Microsoft Dynamics® GP solution,” said Chad Collins, General Manager and Chief Marketing Officer, Accellos. “This partnership is helping to transform our business as we continue to expand our leadership position in the market and create new opportunities with the thousands of retail organizations in SPS Commerce’s Universal Network.”

“Accellos brings a truly world class Microsoft Dynamics® GP solution to the market powered by the SPS Universal Network,” said Peter Zaballos, Vice President of Marketing, SPS Commerce. “Using the SPS Universal Network and our RSX standard, Accellos can provide its customers the nimble, responsive supply chain capabilities required to meet the needs of today’s rapidly evolving retail marketplace.”

The enterprise cloud service for Microsoft Dynamics® GP is immediately available from Accellos and SPS Commerce.

Retail executives will hear more about the new cloud solution from Accellos and SPS Commerce at The Business of Omni-Channel Retail event on October 8, 2013, in New York City.
