What this module does

The Inventory Cost & Valuation Change Notification module monitors two critical inventory events and delivers a structured HTML email to every member of a designated security group the moment either occurs:

• Product cost or price change — triggered when standard_price or list_price is updated on any product template.
• Inventory adjustment valuation entry — triggered when a new stock.valuation.layer record is created by an inventory adjustment (INV: entries, is_inventory flag).

Each email shows: change type, responsible user, product name, old/new cost, old/new price, on-hand quantity before and after, qty difference, total valuation impact, and source reference. Recipients are controlled through the Email Notification Track Product security group — only members of that group receive alerts.

How it works

Overrides write() on product.template and create() on stock.valuation.layer. Both methods fail silently so a notification error never interrupts the user's action.

Key features

Sample notification email

Every alert delivers a structured HTML table directly to recipients' inboxes:

Frequently asked questions

Does the module slow down Odoo product saves?
No. Any notification exception is caught silently so the user never experiences delay or error from the notification logic.

Can I customize the email template?
Yes. The HTML template is a standard mail.template record editable in Odoo's Technical → Email Templates menu.

Does it notify on every product write, even if cost didn't change?
No. The notification fires only when standard_price or list_price keys are present in the write values dictionary.

What if no users are in the notification group?
The method exits gracefully without sending any email and without raising an error.

Is it compatible with multi-company Odoo setups?
The email is sent from the company of the product's valuation layer. Ensure users are assigned to the group in the correct company context.
