Is it permissible to combine a fixed salary with a specific monetary amount for each category (not a percentage of sales), whereby the product is calculated for the distributor at a certain price and he sells it for more, with the difference being his, taking into consideration that the vehicle and driver belong to the company?

Contracting for the distributor to receive anything over one thousand of the item's price is valid only according to the Hanbalis, while the majority view it as an unknown quantity in the wage, rendering the contract invalid. However, if a fixed salary is combined with that, it is not valid even according to the Hanbalis, based on the relied-upon position in their madhhab.
