Payment I posted in error (7)

Ross

I believe the answer is:

deposit

'payment' is the definition.
(deposit is a kind of payment)

'i posted in error' is the wordplay.
'in error' indicates anagramming the letters.
'i'+'posted'='iposted'
'iposted' is an anagram of 'DEPOSIT'.

(Other definitions for deposit that I've seen before include "Plant" , "First instalment" , "Part payment on a purchase" , "Money in bank - part payment" , "Precipitate" .)

I've seen this clue in the Evening Standard.
