Proffered (8)
I believe the answer is:
tendered
'proffered' is the definition.
(tendering is a kind of proffering)
This is all the clue.
(Other definitions for tendered that I've seen before include "Offered as at auction" , "Offered a bid for a contract" , "Put in a bid for a contract" , "submitted" , "Proffered" .)
