Why is the total amount including tax not displayed?

If your quote or invoice does not show the total amount including tax, check the following points:

1. Enable tax management at the application level

Make sure you have enabled tax management via the main menu: "Settings > Taxes".

Once enabled, add at least one tax.

2. Enable tax management at the document level

Verify that you have enabled tax management in your quote or invoice.

To do this, in document editing mode, open the contextual menu and then click the "Settings" button .

3. Verify line items in the document

Verify that your line items (for example, catalog products or services and custom line items) have a tax assigned.
