I finally found a solution that works well without custom development, using Odoo Studio + Automations.

Context

The goal was to compute the sale price of a manufactured product based on the sale prices of its BOM components (margin already included at component level), similar to what action_bom_cost does for costs.

Add a sale price column on the BOM lines

First, I added a sale price column on the BOM lines (coming from the component product).

⚠️ Important point:

All BOM quantities must use the same Unit of Measure as the product sale UoM.

Odoo Studio does not handle UoM conversions automatically.

Example:

• Product sold in hours

• BOM needs 15 minutes → use 0.25 hours in the BOM

Create a computed Studio field on the BOM

I created a Studio computed field on the BOM (e.g. x_studio_prix_de_vente_calcule) with this Python code:

for record in self:
    total = 0.0

    for line in record.bom_line_ids:
        unit_price = line.product_id.list_price or 0.0
        qty = line.product_qty or 0.0
        total += unit_price * qty

    record['x_studio_prix_de_vente_calcule'] = total

Dependencies used:

bom_line_ids

This ensures the value is recalculated whenever BOM lines are modified.

Use an Automation to update the product sale price

Then, I used an Automated Action on the product to compute the final sale price from the BOM(s):

sum(
    line['x_studio_prix_de_vente_calcule']
    for line in record.bom_ids
)

This value is then written into the product’s sale price field.

Result

• Sale price of the finished product = sum of sale prices of BOM components

• No margin recalculation at product level

• Fully compatible with Odoo Studio

• No custom module required

• Works reliably as long as UoMs are consistent

Notes

This approach is intentionally simple and avoids deep dependency chains (bom_line_ids.product_id.list_price) that are not supported in Studio.

For more advanced scenarios (multi-BOM logic, automatic UoM conversion, complex pricing rules), a custom module would be required.
