The '0.0 unit sold' issue in Odoo POS might occur due to the product’s sales data not being properly updated or synced. Ensure that the sales orders are confirmed and that the POS session is properly closed and reconciled. Additionally, verify that your product’s 'Sales' field in the product configuration is linked correctly to the POS interface.

Hi, 

Do you mean that there is no figures on the product image in the POS app when you add items ?
Or do you mean there is no "sold figures" in the backend for that product ?

A screenshot of your issue would be welcome,

Regards

Tony
