One way is for a company to lease a vehicle through Avis Leasing or Sixt Leasing etc. These companies provide a complete package, the vehicle, the servicing, tires, graphics and internal racking fit outs etc and bundle it all into a series of monthly payments.
We work with a number of leasing companies here in Ireland in that way.
Even for a dealer purchase, the person can finance the complete invoice price, which means that you need to work with the dealerships, offer them incentives to promote, the graphics, the internal racking systems etc. It all about collaborating with different companies to provide a complete solution. The dealer then pays you.
