Inventory in Odoo: A Beginner’s Tutorial

Inventory in Odoo forms the backbone of efficient warehouse and stock management. In this tutorial, we focus on Inventory in Odoo to help you track stock levels, configure locations, and automate replenishment rules. Moreover, we include practical examples like setting reorder triggers when forecasted quantity drops below 10 units, and using barcode scanning at internal locations. Therefore, you will gain hands‑on skills and clear steps to master Odoo inventory management.

Understanding Odoo Inventory Levels

First, you must grasp how Odoo structures your stock data. Additionally, you will learn how company, warehouse, and location hierarchies interact. Finally, you will see how lot and serial number tracking works in real time.

Company and Warehouse Hierarchy

1. Company Level

• You define your main company here.
• You can connect multiple warehouses under one company.

1. Warehouse Level

• Each warehouse holds stock in its own locations.
• Odoo lets you enable multi‑warehouse features under Inventory → Configuration → Settings.

1. Benefits

• You monitor stock per warehouse.
• You segregate operations by region or function.

Internal Locations and Transit Locations

Next, you configure specific areas inside warehouses. Odoo categorizes locations into:

• Internal
• Transit
• Vendor bin
• Production
• Customer
• Scrap

For simplicity, use Internal for main storage. Meanwhile, mark Transit for goods in movement. As a result, you avoid miscounting stock during transfers.

Lot and Serial Number Tracking

Moreover, you can track each unit by lot or serial number. You activate this under Products → Inventory:

1. Open a product
2. Under Inventory, set Tracking to “By Lot” or “By Unique Serial Number”
3. Save your changes

Therefore, you maintain traceability and quality control effortlessly.

Configuring Inventory Settings

First, enable core features under Inventory → Configuration → Settings. Then, apply changes.

Enabling Multi‑Step Routes

1. Go to Settings
2. Check Multi‑Step Routes
3. Save

Next, you see new route options like:

• Buy
• Manufacture
• Dropship
• Replenish

These routes let you automate flows from purchase to delivery.

Activating Lot/Serial Tracking

Meanwhile, scroll to Traceability. Then, check:

• Lots & Serial Numbers
• Expiration Dates (optional)

Finally, click Save. You now capture batch and serial data on each stock move.

Adding and Setting Up Products

First, you add new products. Next, you configure their inventory behavior.

Product Types and Tracking Methods

1. Go to Inventory → Master Data → Products
2. Click Create
3. Set Product Type to:

• Stockable Product for physical goods
• Consumable for items you don’t stock

1. Under Inventory, choose Tracking method
2. Save the product

Therefore, you tell Odoo how to treat each item during transactions.

Assigning Locations to Products

Next, you assign default source and destination locations:

1. In product form, switch to Inventory tab
2. Set Routes (e.g., Buy, Replenish)
3. Define Warehouse Locations if needed
4. Save

Now, Odoo knows where to pull and push this product automatically.

Managing Stock Moves and Transactions

First, understand core stock moves: incoming receipts, outgoing deliveries, internal transfers, and scrap.

Incoming Shipments

Next, you manage purchases:

1. Create a Purchase Order under Purchases → Orders
2. Confirm the order
3. Click Receive in the Receipt smart button
4. Validate the incoming shipment

Therefore, Odoo increases your stock at the chosen internal location.

Creating Purchase Receipts

• Go to Inventory → Operations → Receipts
• Select the vendor document
• Click Validate

As a result, you complete the inbound process step-by-step.

Scrapping Items

Meanwhile, you may scrap damaged goods:

1. Go to Inventory → Operations → Scraps
2. Click Create
3. Choose product, quantity, and scrap location
4. Validate

Consequently, Odoo removes that stock and records a scrap move.

Outgoing Shipments

First, you generate deliveries:

1. Create a Sales Order under Sales → Orders
2. Confirm the order
3. Click Deliver in the Delivery Orders smart button
4. Validate the outgoing shipment

Therefore, Odoo decreases available stock and records the delivery.

Automating Reorders with Rules

First, set up reordering rules to avoid manual purchase triggers. Then, configure thresholds.

Defining Reorder Rules

1. Navigate to Inventory → Master Data → Reordering Rules
2. Click Create
3. Select a product and warehouse location
4. Set Min. Quantity and Max. Quantity
5. Define Quantity Multiple (step)
6. Choose a purchase route (e.g., Buy or Manufacture)
7. Save

Next, Odoo automatically generates RFQs when forecast drops below Min.

Example: Reorder When Forecast Falls Below Threshold

For instance, you can:

• Min Quantity = 10
• Max Quantity = 30
• Quantity Multiple = 20

Now, when your forecasted stock dips under 10, Odoo orders exactly 20 units (in multiples of 20) up to a max of 30.

Setting Steps and Max Quantities

Therefore, you:

1. Prevent overstock by capping with Max = 30
2. Maintain order consistency with steps of 20
3. Trigger automatic procurement with Min = 10

Consequently, you balance inventory investment and service level.

Performing Cycle Counts and Inventory Valuation

First, cycle counts keep your records accurate. Next, inventory valuation helps you track asset value.

Configuring Cycle Count Frequency

1. Go to Inventory → Operations → Cycle Counts
2. Click Create
3. Select location and product category
4. Set Frequency (e.g., daily, weekly)
5. Validate

Moreover, you can schedule counts per location group to spread workload.

Analyzing Inventory Reports

Meanwhile, use Inventory → Reporting:

• Inventory Valuation
• Stock Moves
• Reordering Rules

Each report shows live data. As a result, you monitor stock value, turnover, and pending orders.

Best Practices for Odoo Inventory Management

First, follow proven techniques. Next, avoid complexity.

Keep Location Structure Simple

• Start with a few internal locations.
• Avoid deep sub‑location trees.
• Expand only when needed.

Therefore, you reduce configuration errors and counting time.

Use Barcode Scanning for Efficiency

Additionally, enable the Barcode app under Apps. Then:

1. Assign barcode to each product and location.
2. Use a scanner during receipts, deliveries, and cycle counts.

Consequently, you speed up transactions and minimize manual errors.

Document Standard Operating Procedures

Finally, write clear guides:

1. Record each step in product creation, receipts, and deliveries.
2. Include screenshots or video clips.
3. Train your team on Odoo inventory flows.

Therefore, you ensure consistency and fast onboarding.

Conclusion

Inventory management defines your company’s ability to meet demand economically. Moreover, Inventory in Odoo offers a flexible yet powerful framework that adapts to diverse workflows. First, you learned the hierarchy of company, warehouse, and location. Next, you configured settings for multi‑step routes and lot tracking. Then, you added products and managed stock moves for receipts, deliveries, and scraps. Finally, you automated reordering rules and performed cycle counts to maintain accuracy. As a result, you can now streamline your warehouse operations, reduce stockouts, and improve inventory accuracy in Odoo.
