Price, charge (3)
I believe the answer is:
fee
I believe this clue is a double definition.
'price' is the first definition.
(price paid for a service)
'charge' is the second definition.
(fee is a kind of charge)
(Other definitions for fee that I've seen before include "Sum payable to, say, barrister" , "price" , "Cost" , "Charge for professional services" , "Money paid for professional services" .)
