Case Study: WBX Commerce achieves scalable drop‑ship and replenishment growth with SPS Commerce

EDI drives drop-ship and replenishment growth

Whitebox, a Baltimore-based e-commerce and fulfillment partner with a team experienced at Amazon and other online marketplaces, helps high-growth brands scale sales both online and in physical retail. As customers moved into drop-ship and replenishment programs with national retailers, Whitebox faced the challenge of meeting complex, changing retailer trading requirements and handling very high order volumes—capabilities it did not have in-house.

Whitebox partnered with SPS Commerce to combine its fulfillment services with SPS’s scalable EDI technology and retailer expertise. The integration enabled shared customers to comply with retailer EDI requirements, scale capacity (handling up to 100x volumes), shorten lead times via direct-to-consumer drop-ship, and generate new business through mutual referrals—driving measurable growth in drop-ship and replenishment channels.
