6. Weakness: Trial balances of the accounts receivable subsidiary ledger are not prepared independently of, or verified and reconciled to, the accounts receivable control account in the general ledger.
Threat: Any of fees earned, cash receipts, and uncollectible accounts expense could be either understated or overstated because of undetected differences between the subsidiary ledger and the general ledger. Also, fees earned and cash receipts or accounts receivable could be understated because of failure to record billings, cash receipts, and write-offs accurately.
Control: Periodic reconciliation of the subsidiary accounts receivable ledger to the general ledger control account for accounts receivable.
