Proforma (asi/300094) announced Monday that it has launched its 600th client e-commerce store on its ProStores platform, a proprietary online storefront system.​

The Top 40 distributor said it introduced ProStores in 2016 to provide B2B and B2C end-users with a streamlined “Amazon-like” experience for online purchases. According to Proforma, the growing prevalence of online buying, coupled with enhanced ecommerce capabilities of ProStores, has fueled a 33% increase in the number of online company stores the Ohio-headquartered distributor has created since last year.

“We are seeing significant growth in online purchasing, especially in B2B situations where our clients’ priority is to control their brand identity and overall spend,” Brian Carothers, Proforma’s chief technology officer, said in a statement. ProStores, he added, is leading to numerous benefits for Proforma affiliates and their clients. “Both have reported significant time and financial savings by managing large print and promotional programs through ProStores,” he said.

Currently, Proforma uses ProStores to support both mid-sized and Fortune 500 company stores that range in value from $25,000 to more than $5 million in annual sales. Proforma owners offered praise for the platform. “The ProStores e-commerce platform gives me the flexibility to create custom sites for my clients with many unique features,” said Jim Shindler, co-owner of Proforma Graphics Services in Columbus, OH. “One of the most significant advantages the ProStore platform offers is that it blends the best functionality of both print and promo-specific e-commerce systems.”

With reported North American promotional product revenue of $368.9 million, Proforma ranked third on Counselor’s 2017 of the largest distributors in the advertising specialty industry.
