Bound to have everything matched (7)
I believe the answer is:
tallied
'matched' is the definition.
('tally' can be a synonym of 'match')
'bound to have everything' is the wordplay.
'bound' becomes 'tied' (I've seen this before).
'to have' indicates putting letters inside.
'everything' becomes 'all' (I've seen this before).
'tied' enclosing 'all' is 'TALLIED'.
(Other definitions for tallied that I've seen before include "Agreed, corresponded" , "Matched" , "Agreed; calculated" , "Corresponded - kept score" , "Reckoned debt or score" .)
