Hello Ray, I found that the Service Product is not subject to the Control Policy. I tested both of them and found that the results are the same. I still need to update the Received field on the PO manually.

Thank you - I have updated my answer.

Hello Zehntech, I found that the Service Product is not subject to the Control Policy. I tested both of them and found that the results are the same. I still need to update the Received field on the PO manually. I could even create and post a Bill when the Service Product, which was set to On Received Quantity, has not been received yet, that I remembered that it couldn't work in the previous versions.

Hello Giang,

Thank you for testing and sharing your findings.

Yes, your observation is correct. In Odoo 19, the behavior for Service products appears to have changed compared to previous versions. Even when the product is configured with “On Received Quantity,” Odoo now allows the vendor bill to be created and posted without an actual receipt/service receipt validation.

This seems related to the new valuation/accounting flow introduced in Odoo 19, where service-type products are no longer strictly tied to the traditional receipt validation logic.

As a result:

The PO may still appear in “Billed Not Received”
The Received quantity may require manual update/validation for closure
The old blocking behavior from earlier Odoo versions is no longer enforced the same way for services

In our experience, this is more of a functional change/limitation in Odoo 19 rather than a configuration issue. A customization or automated workflow may be needed if you want the PO to close automatically for service purchases after billing.

Hope this works for you! If you need any help implementing this or want a more optimized approach, feel free to reach out for further discussion.
