Retail replenishment is the process of keeping the right products available across stores and channels without tying up unnecessary capital. It sits at the core of effective retail inventory management, helping businesses balance availability, cost control, and customer expectations. By applying the right replenishment strategies, retailers can reduce stockouts, limit excess inventory, and improve cash flow while responding to demand volatility, promotions, and short product lifecycles. Modern retail replenishment combines data-driven planning, automation, and inventory visibility to support consistent decision-making across locations and channels.
