Most organisations would love to have the problem of how to make use of an over-supply of car parking. Much more commonly, management struggles with acute parking shortage. The cost to your bottom line, of losing one valued staff member, because you can't provide a car space, can be high. You should never have to say "no" to a staff parking request when you have a vacant space in your car park.
Parkmonkey licenses a low cost "internal" car park sharing platform that allows a business to reduce wasted space by better sharing a limited resource among staff - like "hot desking", we call it "Hot Parking"
