The ruling on taking extra money in this case

A: As this agent receives a monthly salary from the company he works for, it is not permissible for him to take commission from the other company in return for the purchases he makes for his company. This is because there is a possibility that he will not protect the best interests of the company he works for in terms of the price and quality of the machines he purchases.
