This module adds a check on invoice to force user to set tax on invoice line.
auto_awesome What this module does
AI-generated from the code · Odoo 19.0Prevents posting customer invoices or vendor bills that contain lines without taxes, showing an error that lists the offending invoices and lines.
This module adds a control when invoices are validated. If any invoice line (excluding section and note lines) has no tax set, Odoo blocks the posting and shows a warning titled "No Taxes Defined!" that lists each problematic line with the invoice, the customer and the product concerned.
The warning includes a button "Show invoices with lines without taxes" that opens the affected invoices: directly on the invoice form if only one is concerned, or in a filtered list if several are.
- The check applies to documents treated as invoices (customer invoices and vendor bills) at the moment they are posted.
- Section and note lines are ignored, so only real product lines must carry a tax.
- The check can be forced through a specific context key, and it is automatically skipped while demo data is being installed or upgraded and during automated tests.
- It touches the
account.movemodel and reuses the standard invoice list and form views for the error action.
No new menus, fields or settings are added: the rule works silently in the background and only appears when someone tries to validate an invoice with untaxed lines.
