Hi,

To automatically calculate and display the price per measurement unit (e.g., €/liter) on price tags in Odoo, even when selling per piece, you can use a computed field and a custom report. Add a field to store the product's volume/weight and another computed field to calculate the price per unit based on the sales price and volume/weight. Then, create a custom QWeb report to display the product name, price, and calculated price per unit on the price tag.

Alternatively, if using Odoo POS, you can modify the POS receipt to include the price per unit. For a simpler but less flexible approach, Odoo Studio can be used to add the necessary fields and modify views. Remember to be consistent with units of measure, consider rounding and localization, and integrate barcode information if needed.

Python

from odoo import models, fields, api

class ProductTemplate(models.Model):  # Or ProductProduct

    _inherit = 'product.template'  # Or 'product.product'

    volume_liters = fields.Float(string='Volume (Liters)', default=1.0)  # Or weight_kg, etc.

    price_per_liter = fields.Float(

        string='Price per Liter',

        compute='_compute_price_per_liter',

        store=True,  # Store the computed value for performance

    )

    @api.depends('list_price', 'volume_liters')  # 'list_price' is the standard sales price field

    def _compute_price_per_liter(self):

        for product in self:

            if product.volume_liters > 0:

                product.price_per_liter = product.list_price / product.volume_liters

            else:

                product.price_per_liter = 0.0

Qweb template

<t t-name="my_module.price_tag">

    <t t-foreach="docs" t-as="product">

        <div class="price_tag">

            <h2><t t-esc="product.name"/></h2>

            <p>Price: <t t-esc="product.list_price"/> €/pc</p>

            <p>Price per Liter: <t t-esc="product.price_per_liter"/> €/liter</p>

        </div>

    </t>

</t>

Hope it helps

Hello there,

For this, you first need to configure the UoM.

Here is the 1 pc Bottle =0.75L, so UoM is L(0.75)

And add an attribute in that product w/o the creation of a variant with an extra price.

Then SO would be,

Here 0.75L water means 1 qty of L(0.75)  + with barcode/labeled (0.5)
=> 1.5=0.5=2

Hope this will help you. Before doing this, decide the product will sold on which UoM is L or L(0.75) or any other measure. This will differ accordingly.
