Bill has club set up (3)
I believe the answer is:
tab
'bill' is the definition.
(a tab is a bill at a bar)
'club set up' is the wordplay.
'club' becomes 'bat' (as in sporting equipment).
'set up' is a reversal indicator (in a down clue, letters go up).
'bat' back-to-front is 'TAB'.
'has' acts as a link.
(Other definitions for tab that I've seen before include "Text indent key" , "Small flap - bill" , "Tag" , "Flap; illicit drug pill (slang)" , "Ring pull" .)
