OWE · Lender AR
Everything that changes what the system says we are owed, in one place. An adjustment moves a dollar amount; a net-out stops an account being counted at all. Both need a reason, and both are answerable afterwards — corrections are voided, never deleted.
Final-approved accounts that did not land on zero. Over- and under-paid are reported apart because they are opposite problems — one is money to return, the other money to chase.
