Discreditable charges? (6)
I believe the answer is:
debits
'charges?' is the definition.
(charging is a kind of debiting)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for debits that I've seen before include "Enters in the ledger as due" , "Sums taken from a bank account" , "Ledger entries of what is due" , "Sums that are owing" .)
