A paper valet ticket looks free. It costs a few cents to print and nothing to hand over. The real costs show up later.
Lost stubs cause arguments at the curb and manual verification that ties up a supervisor. Every minute spent proving a car is yours is a minute the line gets longer.
Cash is the other leak. When payments happen on paper and in pockets, nobody can say with certainty what was collected. A digital ledger turns that guess into a number.
A text-based ticket replaces all three: the stub cannot be lost, the payment is recorded as it happens and the guest can see their status. The savings are in the hours your team gets back.
