Hi @Muhammad Usman Anwar,

if you dont want to use the price list then you might need to modify this on code level a little bit. 

For that, Inherit the product.template model and redefine the Sale Price field and add company_dependent=True to the defination.
list_price = fields.Float('Sales Price', company_dependent=True, default=1.0,digits='Product Price',help="Price at which the product is sold to customers.")

for more understanding the company_dependent part please refer to the Cost field (standard_price as technical name) functioning.

Let me know if it helps!
