Hello Odoo Community,

I am working on a requirement where I need to configure taxes for each invoice line with flexibility:

1. The tax for a line can either be a percentage (%) of the line amount or a fixed amount.
2. This setup should allow different invoice lines to have different tax configurations (some as percentages and others as fixed amounts).

Currently, Odoo seems to apply taxes uniformly (as either fixed amounts or percentages) for the entire invoice. I’m looking for a way to make this variable on a per-line basis.

Questions:

• Is there a standard way in Odoo to configure taxes this way?
• If not, would creating custom tax computation logic be the best solution?
• Are there any modules or workarounds that could help with this requirement?

Any insights, suggestions, or references to documentation are highly appreciated!

Thank you in advance for your help!

Best regards,
