Account Reconciliation

Account reconciliation is the process of comparing a general ledger balance to independent supporting evidence, explaining any difference, and resolving items that should not persist. It is the primary detective control over the completeness and accuracy of the balance sheet, and it is the single most common area where auditors identify control deficiencies.

Reconciliations divide broadly by evidence type. Some accounts reconcile to third-party statements — cash to bank statements, debt to lender amortization schedules, investments to custodian reports. Some reconcile to sub-ledgers or detail listings — accounts receivable to the aging, accounts payable to the open payables report, fixed assets to the asset register, inventory to the perpetual listing or count. Others reconcile to internally prepared schedules that themselves must be supported — accrued liabilities, prepaid expenses, deferred revenue, equity, and reserve accounts.

A reconciliation is only as good as its treatment of differences. Timing differences, such as outstanding checks or deposits in transit, are expected and resolve on their own. Unexplained differences, aged unreconciled items, and plugs are the warning signs; a reconciliation that balances only because a residual was forced into a suspense account has not been performed. Aging of open items matters as much as the ending difference.

Quality standards that hold up under audit include independent preparation and review with documented sign-off, completion within a defined number of days after period end, reconciliation to source evidence rather than to another internal report, and a stated resolution plan for every aged item. Firms typically maintain a reconciliation inventory identifying every balance sheet account, its owner, frequency, and risk rating, so that coverage can be demonstrated rather than assumed.
