The Winsupply Preferred Vendors that won in each category were chosen by Winsupply local companies.

“This past year was unprecedented and full of unforeseen challenges,” said Amy Souders, Winsupply’s vice president of vendor relations. “Through it all, Winsupply local companies managed to be amazingly successful. We are so appreciative for our vendor partnerships and the support they’ve provided.”

Nominees were based on several criteria, the most important of which was being a leader in growing the segment's business over the past year. They were also judged on selling to a breadth of locations that buy the vendor’s product, providing strong support at the local level, and consistent volume and growth.
