The article discusses the best inventory management software of 2026, with experts testing and reviewing reviews of Odoo, a free standalone module with unlimited users and real-time tracking, multi-warehouse support, barcode scanning, and automated replenishment. Odoo's pricing stands out among the ERP crowd due to its pricing, which includes a free Inventory app and a double-entry inventory system that automatically tracks stock movement without manual inputs. The company's real power comes when you connect Inventory to the rest of the Odoo ecosystem, which allows for sales, purchasing, accounting, and manufacturing to adjust stock levels automatically. However, once you add a second app, the Standard plan will cost $31.10 per user per month and the Custom plan costs $46.70 per user.
