Supply dealt with? I applaud you! (4,4)

I believe the answer is:

well done

'i applaud you' is the definition.

'supply dealt with?' is the wordplay.
'supply' becomes 'well' (in a good, skilful or supple way).
'dealt with?' becomes 'done'.
'well'+'done'='WELL-DONE'

(Other definitions for well done that I've seen before include "expression of approval" , "thoroughly prepared" , "How one might like one's steak?" , "Bravo!" , "By no means rare" .)

I've seen this clue in The Guardian.
