Immediate credit arranged (6)
I believe the answer is:
direct
'immediate' is the definition.
(similar in meaning)
'credit arranged' is the wordplay.
'arranged' indicates an anagram.
'credit' is an anagram of 'DIRECT'.
(Other definitions for direct that I've seen before include "Straight; manage" , "Show where to go - straight" , "Order; straight" , "Following the quickest and shortest path" , "Take charge, of a film perhaps" .)
