Trim and dispatch form
I believe the answer is:
shipshape
'trim' is the definition.
('shipshape' can be a synonym of 'trim')
'dispatch form' is the wordplay.
'dispatch' becomes 'ship' (I've seen this before).
'form' becomes 'shape' ('shape' can be a synonym of 'form'**).
'ship'+'shape'='SHIPSHAPE'
'and' acts as a link.
(Other definitions for shipshape that I've seen before include "Neat, orderly" , "Exhibiting neatness" , "Neat and well-kept" , "Ordered" , "fashionable in Bristol" .)
