Using Loyverse POS 3 sites one company

[BurgerTruck]

Can you please help we have a company The Burger Truck we have 3 mobile street food trucks that go to various sites we are currently using sumup and its becoming very complicated with the POS and stock levels it keeps combining the three trucks together. I really like loyverse can we use loyverse as POS on each truck? with different stock levels? With the trucks can we use iphones with the loyverse running it ?

Also whats the best mobile app for food ordering integration with loyverse?
