Are pick-up and drop-off rates round-trip or one-way?

Dog boarding and doggy daycare both include the option of setting rates for pick-up and drop-off services. If I say $15, for instance, is that $15 for both picking up and dropping off for a single booking, $15 for picking up at the beginning of the stay and another $15 for dropping off at the end, or $15 each time I go there and $15 each time I come back (totalling $60)? Thank you!
