Case Study: Merz Apothecary achieves $7.5M in Amazon sales and real-time omnichannel inventory with Celerant Technology

Merz Apothecary Integrating with Amazon to Make Millions

Merz Apothecary, a 142-year-old specialty pharmacy in Chicago with two stores, a catalog, a website and Amazon presence, was generating $15–20M in revenue but struggled with fragmented homegrown systems. Lacking real-time store and online inventory, manual marketplace management and inconsistent pricing/promotions led to oversells, inventory inaccuracies and operational strain as the business scaled.

Merz implemented Celerant Command Retail, a single, all‑in‑one retail management system with unified inventory, pricing/promotions and seamless Amazon FBM/FBA integration. The change eliminated legacy tools, provided real-time visibility across channels, automated fulfillment and inventory control, and drove Amazon sales to about $7.5M—roughly half the company’s business—while letting the team focus on retail rather than technical integration.
