Hello yes thank you very much!!! 

And any help about how to set the cost per liter or per chilogram in products?

Hi,

To display the price per unit including VAT and the cost per unit of measure on the product label template, follow these steps:

1. Go to Settings --> Technical --> Views.

2. Search for the template format you want to modify, such as 'report_simple_label2x7', 'report_simple_label4x7', 'report_simple_label4x12', or 'report_simple_label_dymo'.

3. Add the following code to the appropriate position within the template. For example:

<t t-esc="'Cost per ' + product.uom_name + ': ' + '%.2f' % product.standard_price + ' per ' + product.uom_name"/>

<t t-esc="'Price per Unit (incl. VAT): ' + '%.2f' % (product.list_price * (1 + (product.taxes_id.amount / 100)))"/>

Hope it helps
