Tracking lot or serial number products with FBA orders

When working with products tracked by lots or serial numbers, Amazon’s API does not send the specific tracking information for each sale. As a result, Odoo cannot assign the required tracking numbers, which leads to synchronization errors.

To avoid this issue, configure a product kit in Odoo that represents the Amazon product. When an FBA order is imported, Odoo processes the kit instead of the tracked product, preventing sync failures.

When replenishing Amazon stock, transfer the tracked product to the WH/Amazon location. This ensures proper inventory tracking and records stock movement at the time of transfer rather than at the time of sale.

Note

The WH/Amazon location is automatically created when the first Amazon account is connected.

With this approach, kit product quantities may remain negative. This is expected behavior, as actual inventory is managed through transfers to the Amazon location.

Important

This method does not track the exact lot or serial number used in each sale. Its purpose is to allow order synchronization without errors.

Settings

To implement this workflow, ensure the following apps are installed:

• Sales app: Required to connect an Amazon account

• Inventory app: Needed for managing stock across warehouse locations

• Manufacturing app: Used to create Bills of Materials (BoM) for kits

Create a product kit

To handle tracked products correctly, create a kit that represents the Amazon listing.

1. Go to Sales app ‣ Products ‣ Products

2. Click New

3. Create a product configured as a kit

Important

Do not enable Track Inventory for the kit product.

Link the Amazon SKU to the product kit

Next, map the Amazon product to the kit:

1. Go to Sales app ‣ Configuration ‣ Offers

2. Click New

3. Select the Amazon marketplace

4. Choose the kit product

5. Enter the Amazon SKU

Note

This step intentionally removes the direct link between the SKU and the tracked product.
Since Odoo cannot assign lot/serial numbers during sync, keeping that link would cause repeated failures.

By linking the SKU to the kit instead, the system bypasses the tracking requirement and completes synchronization successfully.

Create the BoM for the product kit

Now define the kit structure:

1. Go to Sales app ‣ Products ‣ Products

2. Open the kit product

3. Click the Bill of Materials smart button

4. Create a kit BoM

In the Components tab:

• Add the original tracked product (lot/serial tracked)

Important

The tracked product must be the only component in the BoM.

Once configured, Odoo will process Amazon FBA orders using the kit, allowing smooth synchronization while maintaining internal stock tracking through warehouse transfers.
