Odoo Inventory is a full-featured warehouse management system (WMS) built into the ERP. It handles product tracking, multi-warehouse operations, barcode scanning, automated replenishment, lot and serial number tracing, and integrates natively with Sales, Purchase, and Manufacturing. This guide covers setup, key features, and best practices.

Initial Setup

  1. Enable Inventory: Apps → Install Inventory
  2. Configure Warehouses: Inventory → Configuration → Warehouses. Set routes (1-step, 2-step, or 3-step)
  3. Set up Locations: Define storage locations within each warehouse
  4. Create Products: Set product type (Storable, Consumable, Service) and tracking method
  5. Configure Reordering Rules: Set min/max stock levels per product per warehouse

Common Workflows

Receiving Goods

Purchase orders create receipts. Staff validate receipts confirming quantities and scanning barcodes. Stock updates automatically.

Shipping Orders

Sales orders trigger delivery orders. In 3-step: pick → pack → ship, each with its own validation for fulfillment visibility.

Best Practices

  • Start with 1-step, move to multi-step as operations grow
  • Enable barcode scanning for 20+ orders/day
  • Use reordering rules on all storable products
  • Integrate with Purchase for automated replenishment

Hosting Considerations

Inventory-heavy operations generate significant database activity. Ensure adequate RAM and SSD storage. DeployMonkey's automated S3 backups protect inventory data. See server requirements and Odoo for inventory management.
