Law Firm Bank Reconciliation: How One Firm Found a Double Payment

Law Firm Bank Reconciliation: How One Firm Found a Double Payment

Illustrative anonymized composite, drawn from recurring patterns rather than a single engagement. The firm named below was not involved in it. Every dollar figure is invented and rounded. Nothing here is guaranteed or predictive.

Law firm bank reconciliation usually gets attention where the risk feels highest, which is the trust account. That makes sense, and it also leaves the operating account unwatched. In this composite, a small litigation firm reconciled its trust account every month for years and had not reconciled its operating account for four months, and the gap cost it a payment it did not know it had made twice.

The firm has four lawyers and two staff. The managing partner assumed the operating books were fine because the software showed a balance and checks were clearing. Legal Ease, a Fort Worth bookkeeping firm that specializes in law firms, fits one stage of the story: doing the reconciliation and tracing what it found. Legal Ease is a vetted Sam's List member and a paying member of our featured program; payment does not buy the language we use or its reviews.

Why the Operating Account Went Unreconciled

The firm's office manager reconciled the trust account on the first of every month because the bar expected it, and she had been trained to treat it as the account that could end a career. The operating account felt different. It held the firm's own money, so a mistake seemed to cost only money.

There was a second reason. The accounting software was connected to the bank feed, and transactions flowed in and were categorized automatically. It looked reconciled. Nobody had matched the book balance to the statement, so nobody knew whether the feed had dropped, duplicated or mislabeled anything.

Four months passed this way. During that time the firm changed payment methods for several vendors, moving from checks to a firm credit card, which is exactly when duplicates tend to appear.

The limitation of this pattern is that a bank feed is not a reconciliation. The feed shows what the bank reported. A reconciliation proves that what the books say agrees with what the bank says, and it is the step that surfaces the difference.

How a Law Firm Bank Reconciliation Surfaced the Problem

The firm engaged a bookkeeper to clean up the operating account before a line of credit renewal. The first job was to reconcile the account month by month, oldest first, so that each month's ending balance became the next month's starting point.

The first month tied out. The second showed small differences, which came later. The third showed a gap of $4,860 between the books and the bank. The bookkeeper listed every transaction in that month and matched each to a statement line. Most matched at once. A few were timing items, checks written in the month that cleared later.

One did not. A software subscription for the firm's case management platform, $4,860 for an annual renewal, appeared on the bank statement twice. It had been paid by a check written in the first week of the month and again by an online bank payment two weeks later, after the vendor sent a second invoice and a staff member paid it without checking.

The limitation: a reconciliation finds differences, not their cause. The bookkeeper had to trace each one back to a source document, and the duplicate only became clear when both payments were laid next to the vendor's invoices.

Recovering a Duplicate Vendor Payment

Finding a duplicate vendor payment is half the job. Getting the money back is the other half, and it depends on the vendor and on how the second payment was made.

The firm contacted the vendor with both payment confirmations and the invoice number, and asked for a refund of the second payment. Because the second payment had been made electronically, the vendor could send that one back. In the composite, the vendor processed the refund within a few weeks, and the bookkeeper recorded it as a reduction of the expense, not as new income.

Here is the illustrative shape of the four unreconciled months once they were finished. Every figure is invented and rounded:

Item	Amount
Total difference across the four months	$6,690
Duplicate vendor payment	$4,860
Unrecorded bank fees	$420
Deposit recorded twice in the books	$1,030
Remaining unexplained (the $380 deposit below)	$380

The duplicate was the largest item, but not the only one, and one $380 deposit stayed unexplained, as described below. The bank fees had never been booked, and one client payment had been entered twice in the books, which overstated income for the month.

The limitation: these are illustrative amounts, not a typical result. The refund depended on the vendor's cooperation and on the payment method, and a check paid twice can be harder to recover than an electronic payment.

Law Firm Bank Reconciliation Going Forward: The Operating Account Monthly

The lesson was not that one person made a mistake. It was that the firm had no step that would have caught it. The fix was a monthly routine: reconcile every bank and card account, not only the trust account, and do it within a few weeks of the statement date.

The firm set three rules. First, every account that holds money gets reconciled each month, including the credit card. Second, anything that cannot be matched is investigated while the memory is fresh, and not carried forward. Third, a second person looks at the reconciliation and signs it, even if the second person is the managing partner and the review takes ten minutes.

They also added a small control to purchasing: before paying an invoice, check whether it has already been paid. That is the sort of control a bookkeeper can build into a routine.

The limitation: controls add small amounts of time to every payment, and a small firm has to decide how much is worth it. A single review step at month end catches most of what is worth catching.

Where Legal Ease Fits

Work like this sits squarely in law firm bookkeeping: reconciling more than one account, tying differences to source documents and setting a repeatable routine. It is the kind of work Legal Ease lists. It is based in Fort Worth, Texas, founded in 2016, with 12 employees, serving clients nationwide. It was not involved in this composite. Its live profile describes a law firm bookkeeping specialty and names SMB Owners, Solo and small law firms and Solopreneurs as specialties.

Legal Ease has 9 verified client reviews on Sam's List. Each review is submitted by an individual who identifies as a client of the firm and rates it on communication, subject-matter knowledge, and overall satisfaction. Reviews reflect those individual experiences and do not represent an endorsement by Sam's List. Legal Ease is a paying member of our featured program, and payment does not buy its reviews. Ratings and rankings are not indicative of future performance or results.

The limitation, plainly: the profile lists a $500,000 revenue minimum, so a smaller practice may fall outside what it takes on. Ask which accounts it reconciles, how often, and who reviews the work before it is final.

What Stayed Unresolved

Not everything closed cleanly in this composite. One deposit of $380 on the statement never matched any client or matter. The firm checked its payment platforms and its emails and found no source, and the composite ends with the amount held in a suspense account and flagged for the next review, not written off.

The firm also had to decide whether to tell the bar about anything. The trust account had been reconciled all along and nothing in it was wrong, so there was nothing to report, but the partner asked a lawyer to confirm that, which is the right instinct whenever trust funds are involved.

The practical lesson is narrow. A bank feed shows you what happened. A reconciliation shows you whether your books agree with it, and the second is the one that finds a payment made twice.

Frequently Asked Questions

What is a law firm bank reconciliation?

It is the monthly process of matching the firm's book balance to the bank statement for an account, explaining any difference and recording missing items. Firms reconcile trust accounts, operating accounts and credit cards. The goal is books that agree with the bank.

Do I need to reconcile my operating account if I reconcile trust?

Yes. Trust reconciliation is typically required by the bar, but it does not check your operating account. Errors such as duplicate payments, unbooked fees and double-entered deposits can sit in the operating account unnoticed unless you reconcile it too.

How do I find a duplicate vendor payment?

Reconcile the account and trace each unmatched item to a source document. Sorting payments by vendor and amount can show two of the same size in a short time. Then ask the vendor for a refund with both payment confirmations and the invoice number.

How often should a law firm reconcile its operating account?

Monthly is the common standard, shortly after the statement closes. A reconciliation done promptly finds a mistake while records and memories are fresh. One done every few months turns a small mistake into a long investigation.

If you have only been reconciling the trust account, start with last month's operating statement and match it line by line. You can browse bookkeepers on Sam's List, including the firm above, and ask each one how it handles a multi-account reconciliation.
