INVENTORY & ERP

The best eCommerce inventory & ERP software

By Marcus Taylor · Ecommerce SoftwareUPDATED JUN 16, 2026 · 5 TOOLS

Once you sell on more than one channel, stock and orders stop fitting in a spreadsheet. Inventory and ERP tools keep them in sync — syncing stock levels, routing orders and feeding your accounting.

Cin7 is the workhorse with transparent pricing; Brightpearl and Linnworks suit higher-volume omnichannel retailers; Katana adds manufacturing; Inventory Planner sits on top and forecasts what to reorder.
