Case Study: BILLY Footwear achieves scalable, accurate fulfillment with ShipStation

How SAP Business One and ShipStation Improved Fulfillment for BILLY Footwear

BILLY Footwear, founded in 2015 to create accessible shoes using Universal Design, grew rapidly across retail, marketplace and direct channels (260% sales growth year‑over‑year). That omni‑channel expansion strained inventory and fulfillment: retailers and direct customers pulled from the same stock, previous 3PLs mismanaged big B2B orders, and the team needed a scalable technology stack to streamline accounting, inventory and shipping.

BILLY implemented SAP Business One with OptiProERP and integrated ShipStation (via Alluvia) and Shopify to create a single fulfillment hub. The unified setup improved reporting, enabled earmarked inventory, introduced scan‑to‑verify workflows, reduced manual work, increased daily order throughput and accuracy, and boosted customer satisfaction while making future growth more manageable.
