Reputation state bank gets from customer (8,5)
I believe the answer is:
standing order
'bank gets from customer' is the definition.
(a standing order is a type of bank payment)
'reputation state' is the wordplay.
'reputation' becomes 'standing' (I've seen this before).
'state' becomes 'order' (order is a kind of state**).
'standing'+'order'='STANDING ORDER'
(Other definitions for standing order that I've seen before include "Instruction to bank for payment at regular intervals" , "gets you on your feet!" , "rise!" , "Arrangement made with bank to pay" , "Instruction for bank to make regular payments" .)
