Ecommerce inventory management software is a system that helps businesses track, control, and manage inventory across online stores, marketplaces, warehouses, and physical locations. It centralizes stock data to improve visibility and support replenishment decisions.

Shopify’s built-in inventory features are sufficient for small ecommerce businesses with simple needs. As complexity increases, businesses often require additional tools for demand forecasting and inventory planning.

Ecommerce brands with demand volatility, multiple sales channels, or large SKU assortments benefit from demand planning software. Accurate forecasting and inventory optimization help reduce stockouts, excess inventory, and manual planning effort.
