What does reconciling an account involve? At its simplest, it means comparing your own records against the bank statement for the same period, item by item, until the two balances agree and every remaining difference has a written explanation. Law firms do this every month, and regulators expect proof that somebody did.
The task sounds clerical. It is not. For a firm holding client money, reconciliation is the control that catches a misposted transfer before it becomes a shortfall, and a shortfall in a trust account is a disciplinary problem rather than an accounting one. So the half hour nobody wants to spend turns out to be the half hour that matters most.
What does reconciling an account involve in plain terms
What does reconciling an account involve once you set the jargon aside? Three balances and one question. You take the bank closing balance, your internal ledger balance, and, for trust money, the total of all individual client balances. Then you ask why any of them differ.
Differences are perfectly normal. A check written last week may not have cleared, and a deposit made on the thirty-first often lands on the first. Reconciliation never eliminates those timing gaps. It accounts for them, names them and carries them forward.
The three-way reconciliation every firm owes
Business accounts need a two-way match: bank against ledger. Trust accounts need a third leg, because the firm holds money belonging to many different clients in one pooled place.
So three figures must agree exactly: the adjusted bank balance, the trust ledger control total, and the sum of every client’s individual balance. If the first two agree while the third does not, one client’s money has drifted into another client’s column. That is precisely the error the third leg exists to catch.
Operating accounts deserve the same discipline, even though the rules sit lighter there. A firm that reconciles its own cash every month spots duplicate vendor payments and card fraud early, and both of those cost real money.
Reconciling an account vs balancing a checkbook
A checkbook balance asks whether you know how much money you have. Reconciling an account asks whether you can prove it to somebody else, months later, without relying on memory.
That difference shows up in the documentation. A proper reconciliation produces a dated report, a list of outstanding items and a signature. Nobody audits a mental arithmetic exercise, whereas a regulator will quite happily ask to see twelve months of reconciliation reports.
What does reconciling an account involve month to month
What does reconciling an account involve once the statement arrives? Start by agreeing the opening balance to last month’s closing figure. Then tick off every deposit and every payment that appears on both sides, leaving only the exceptions.
Next, list what appears on one side alone: outstanding checks, deposits in transit, bank fees nobody recorded, interest credited quietly. Adjust your ledger for the items that genuinely belong there. Finally, confirm that the adjusted figures agree, then write down the date you did the work.
The documents you need before you start
Gather the bank statement, the firm cash ledger for the period, the client ledger listing for trust work, and last month’s completed reconciliation. Missing any one of those turns a thirty-minute job into a lost afternoon.
Deposit slips and cleared check images help enormously when something refuses to match. Most banks keep both online, although retrieval windows vary, so download them while the window is open rather than at the moment you need them.
Decide where the finished reconciliations will live before you produce the first one. A dated folder, whether on paper or inside the document system, beats a mailbox search three years later when somebody finally asks.
Trust accounts, and why the rules tighten there
Client money carries obligations that ordinary operating cash does not. A lawyer must keep it separate, must never borrow against it, and must reconcile it on a defined schedule. The ABA model rule on safekeeping property sets out duties that most states adopt in some form.
State rules then add detail, and they vary considerably. Some demand monthly three-way reconciliation with a retained report; others set a longer interval yet require records for five to seven years. So check your own jurisdiction rather than any general summary, including this one.
Mistakes that turn a small difference into a complaint
The most dangerous habit is forcing the balance. Posting a plug entry so two columns agree hides exactly the error the exercise exists to surface, and it compounds quietly every month afterwards.
Second, many firms let one person both move money and reconcile it. Separating those duties costs almost nothing in a small office, because the reviewing partner only needs to read and sign. Third, some practices reconcile the bank balance yet never the client ledger listing, which leaves the third leg entirely unchecked. Finally, carrying an outstanding check for six months without chasing it eventually becomes an unclaimed property problem.
Rushing the month-end close rounds out the list. Reconciling on the day the statement arrives catches problems while everybody still remembers the transactions, and memory fades considerably faster than anyone expects.
What to check when the account will not reconcile
Start with the size of the difference, because the number often names its own cause. A gap divisible by nine usually means transposed digits. A gap that equals exactly twice a transaction amount suggests a posting with the wrong sign.
Then check the ordinary suspects: an entry recorded in the wrong month, a duplicate payment, a bank fee nobody saw. If the difference persists, compare this month’s outstanding items against last month’s list, since stale items hide there very comfortably. The AICPA publishes general guidance on reconciliation controls that applies well beyond accounting firms.
Set a materiality rule in advance, and set it low. Many firms investigate any difference at all in trust, and a few dollars in an operating account still deserves a look, because small errors frequently share a cause with large ones.
How reconciling an account fits firm operations
What does reconciling an account involve operationally? It sits downstream of billing and trust transfers, so clean upstream habits make it fast. Firms that record a transfer the day it happens finish in minutes, while firms that record transfers in batches spend hours hunting for them.
Software helps here more than almost anywhere else in a practice. Our guides to cloud based legal billing software and law practice management software cover tools that hold client ledgers and the operating ledger in one system, which removes most of the manual matching.
Frequently asked questions about reconciling an account
How often should you reconcile a trust account?
Monthly at minimum, and many states require precisely that with a retained report. Some firms reconcile weekly when transaction volume runs high, which makes any error far easier to trace.
What does reconciling an account involve for a small firm?
The same three balances, simply with fewer lines. A two-lawyer practice can finish a clean month in under an hour, provided somebody records transfers promptly rather than monthly.
Who should do the work?
A bookkeeper or administrator prepares it, and a lawyer reviews and signs. Responsibility stays with the lawyer regardless of who holds the calculator.
The practical takeaway
What does reconciling an account involve in the end? A fixed date, three balances and a signature. Keep the report, the outstanding items list and that signature together, because a regulator will ask for all three at once. Never force a balance, and never let the person who moves the money also prove that it moved correctly. Firms rarely lose a trust account through theft. They lose it through a difference nobody chased for nine months.
