Price, cost (3)
I believe the answer is:
fee
I believe this clue is a double definition.
'price' is the first definition.
(I've seen this before)
'cost' is the second definition.
(fee is a kind of cost)
(Other definitions for fee that I've seen before include "Charge for professional services" , "Amount paid for job" , "(Entry) charge" , "price" , "Payment to a professional for services" .)
