Case Study: BILLY Footwear achieves streamlined, scalable omnichannel fulfillment with OptiProERP

How SAP Business One and ShipStation Improved Fulfillment for BILLY Footwear

BILLY Footwear, a maker of accessible shoes, was selling through big-box retailers, marketplaces and its own ecommerce store and—after a 260% sales increase from 2018 to 2019—struggled to manage inventory, orders and fulfillment across channels. To gain a scalable backend, the company chose SAP Business One as its ERP and engaged OptiProERP to tie that system to ShipStation, Shopify and EDI integrations to create a single, accurate view of inventory and orders.

OptiProERP implemented the integrated solution, connecting SAP Business One to ShipStation and other sales channels to automate order-to-fulfillment workflows, enable scan-to-verify packing, and earmark inventory for specific vendors. As a result, BILLY Footwear can process more orders per day, reduce packing and shipping errors, improve customer satisfaction, and free the team to focus on growth—demonstrating OptiProERP’s role in simplifying fulfillment and supporting scalable expansion.
