Is it permissible to own a transport company which delivers food to customers like fast-food chains? The company has no say in what the customers are sell and only performs the delivery.
It is permissible to deliver all types of food to customers, with the exception of pork, for it is not permissible to serve it or deliver it based on obligatory precaution. Therefore, you must stipulate a condition with the contracting restaurant to exclude food parcels that contain pork from your deliveries.
