Hi,

Why This Happens:

    Pricelists and product data are company-specific in Odoo.

    When you switch the company:

        Odoo reloads product data for that company

        If that company has no vendor price defined for the selected product, the price shows as 0.00

    Even if the currency is the same, the product record for the new company may not contain supplier info or price rules.

How to Fix or Work Around This

Define Vendor Prices Per Company

Go to: Purchasing > Products > Vendors (on the product form)

For each product:

    Add vendor info for each company

    Set prices, currency, delivery lead time

This ensures that when you switch companies, Odoo finds the correct vendor price.

Hope it helps
