To Be Settled, To Be Paid, To Be Supplied, To Be Delivered
intransitive verb, godan verb
If 納める is "to supply" or "to deliver," then this word is when things have been delivered: so it's to be satisfied or to be settled. You aren't doing the supplying, and you know this because if you were to be caught supplying your reputation would be marred (まる for life).
The reading is the same as 納める.
I don't think they will be satisfied with just money.
