What makes a bank or card reconciliation complete in a CAS engagement?
Every component of the difference between statement and ledger is named, dated and still legitimately expected to clear. Balancing is arithmetic; reconciling means no part of the difference is unexplained. Unresolved items are aged on the face of the schedule, and write-offs are the CPA firm’s decision.
A reconciliation can balance without reconciling. The totals agree, the file looks finished, and somewhere inside it an unexplained amount has been pushed into a clearing account to make the arithmetic work. Nothing about the document signals the difference, which is why that condition routinely survives several periods.
Reconciliations are the foundation the rest of a close sits on, so the standard applied to them sets the ceiling on everything built above. This is part of CAS production support and traces to the same recurring bookkeeping work as bank and credit-card reconciliation.
Balanced and reconciled are different claims
Balanced means two totals agree. Reconciled means every component of the difference between them is identified and legitimate. A reconciliation is complete when a reviewer can read the list of reconciling items and understand each one without asking a question — not when the bottom line reaches zero.
The plug entry is how the two separate. It is almost never dishonest; it is usually somebody out of time who intends to come back to it. What makes it costly is that it removes the only visible sign that something is open.
Age belongs on the face of the schedule
The single most useful fact about an unresolved item is how old it is. A check outstanding a few weeks is ordinary; the same check outstanding across several periods is a question about whether it will ever clear.
When age is not shown on the reconciliation, every preparer re-establishes it from scratch each cycle — which is the recurring cost described in ledger hygiene, arriving through a different door. Carrying the period of origin beside each item costs nothing once and saves the re-derivation every time.
Why card reconciliations fail more often
Bank activity usually has one counterparty and one document per transaction. Card activity arrives as many small charges whose receipts sit with whoever made the purchase, so the reconciliation depends on a document-collection process that lives outside the ledger entirely.
That changes what the recurring problem is. It is rarely a mis-posted charge; it is a correctly posted charge with no support behind it. A charge with no receipt should be coded to what the available evidence supports and listed as an exception with its amount, date and merchant. Choosing a plausible account and saying nothing produces the worst available outcome: a ledger that looks complete, is not supportable, and carries no signal that anything is missing.
Reconcile early, not last
Accruals, management reporting and any analytical review all assume the cash and card accounts are settled. Leaving reconciliations to the end of the close means discovering the largest problems at the moment there is least time to deal with them.
Reconciling as soon as statements are available, then building the period on top, is also what makes the staggering in a close calendar work across a book of clients.
Continuity is the part most files cannot prove
A reconciliation file should hold the statement it was prepared against, the unresolved items with their dates and amounts, and a note of what has been resolved since the prior period.
That last element is the one usually missing, and it is the one that lets a reviewer confirm the previous period’s open items were dealt with rather than quietly dropped. Without it, checking continuity means pulling the prior period — re-performance rather than review, which spends the licensed capacity a firm cannot quickly add.
What stays with the firm
Writing off an uncleared item, reissuing it, or deciding it may remain outstanding all change the recorded position, so each is the firm’s instruction and for some clients the firm’s conversation with the client. A preparer has neither the authority nor the context to judge whether the amount matters to the statements.
Preparation identifies the item, quantifies it and states how long it has been open. The decision, and the sign-off on the period, remain with the CPA firm.
