Odoo 18's Inventory app manages stock as a chain of recorded moves: every receipt, internal transfer, delivery and scrap is logged against a location, so quantities on hand and inventory value are derived rather than typed in. It handles multiple warehouses and internal locations, lot and serial traceability, minimum/maximum reordering rules, and standard, FIFO or average-cost valuation that posts to Accounting on its own.
If your business involves physical products — whether retail, wholesale, or manufacturing — inventory management is critical. Odoo 18's Inventory app helps you track every product movement, eliminate stockouts, and reduce overstock.
It's fully integrated with Sales, Purchase, and Accounting, making it a complete ERP solution for supply chain and operations teams.
Warehouse and Location Management
Odoo supports single or multi-warehouse environments. Within each warehouse, you can define specific storage locations — like aisles, shelves, or bins — to enable granular tracking of inventory.
Highlights
- Configure multiple warehouses
- Create internal stock locations (Zone A, Bins, Shelves)
- Route products automatically between locations
- Track incoming and outgoing shipments
This structure helps larger businesses organize complex inventory operations with ease.
Product Tracking and Configuration
Every product in Odoo can be categorized, labeled, and tracked — even down to the serial number or lot number if needed.
Key features
- Track by serial/lot number
- Set expiration dates for perishable goods
- Assign barcodes for quick scanning
- Manage product variants (size, color, etc.)
You can also create product bundles and kits for manufacturing or sales purposes.
Stock Moves and Transfers
Odoo records every stock move — whether it's a purchase, internal transfer, sale, or return.
Types of stock movements
- Receipts: Goods arriving from a vendor
- Internal Transfers: Moving stock within warehouses
- Deliveries: Shipping out to customers
- Scrap: Removing damaged or expired items
Each move is logged with date, location, and responsible user, giving you a full audit trail of inventory activity.
Automated Reordering Rules
Never run out of stock again. Odoo allows you to define minimum and maximum stock levels for any product. When stock dips below the minimum, it automatically triggers a purchase or manufacturing order.
Benefits of automation
- Maintain optimal stock levels
- Reduce manual purchase tasks
- Avoid stockouts and lost sales
You can also integrate lead times and vendor delivery schedules for more accurate planning.
Inventory Valuation and Accounting
Inventory has a direct impact on your bottom line. Odoo supports both manual and automated valuation methods — and integrates tightly with the Accounting app.
Supported methods
- Standard price
- FIFO (First-In, First-Out)
- AVCO (Average Cost)
Stock movements create journal entries automatically, so your financial statements always reflect real-time inventory values.
Real-Time Reporting and Dashboards
From stock age to forecasted inventory, Odoo gives you detailed reporting tools to monitor inventory health and performance.
Sample reports
- Stock on Hand
- Inventory Valuation
- Product Moves
- Demand Forecast
Visual dashboards help warehouse managers make fast, data-driven decisions.

Questions we get asked
Which inventory valuation methods does Odoo 18 support?
Odoo 18 offers three costing methods, set on the product category: Standard Price, First In First Out (FIFO) and Average Cost (AVCO). LIFO is not a costing method in Odoo — it exists only as a removal strategy, which decides which lots leave the warehouse first. Each category also chooses between manual (periodic) and automated inventory valuation.
What is the difference between lot and serial number tracking in Odoo 18?
A serial number identifies one single unit, so Odoo 18 follows each item individually from receipt to delivery. A lot number identifies a batch that many units share, which suits food, chemicals or components bought in production runs. You pick the mode per product once Lots & Serial Numbers is enabled in Inventory settings, and either one gives you a full traceability report.
Does Odoo 18 create accounting entries when stock moves?
Only when the product category uses automated inventory valuation. With that setting, Odoo 18 posts a journal entry to the stock accounts each time goods are received or delivered, so the balance sheet follows the warehouse without anyone re-keying it. With manual, periodic valuation nothing is posted automatically and you record the stock value yourself from the inventory valuation report.
Can Odoo 18 handle expiry dates on perishable stock?
Yes. Switch on Expiration Dates in Inventory settings and lot-tracked products gain removal, best-before, end-of-life and alert dates. Odoo 18 can then warn you before a lot expires and apply the FEFO removal strategy, which picks the lot expiring soonest rather than the oldest one received. Expired stock is taken out with a scrap, so it leaves the on-hand quantity but keeps its history.
How do I record damaged or lost goods in Odoo 18?
Use the Scrap action, available from a product, a lot or a transfer. Odoo 18 moves the quantity to a virtual scrap location instead of deleting it, so stock on hand drops while the move stays visible in the traceability report and the audit trail. If the product category uses automated valuation, the scrap also posts the write-off to your stock valuation accounts.
