Evology Pre-Booking allows businesses to list spaces in their car parks on the Evology Parking app. Motorists looking for somewhere to park can select these spaces and pay for parking before they arrive. Pre-booking lets motorists plan ahead and take care of their parking in advance, while letting businesses drive new visitors to their site and tap into new revenue streams.
