The Best Month-End Close Process for Law Firms

The Big Picture

Your law firm can have money in the bank and still have financial problems hiding beneath the surface. An unpaid invoice, an old trust balance, a duplicated expense, or a transaction posted to the wrong account may not look serious on its own. But when these issues build month after month, your financial reports stop telling you what is actually happening in your firm.

A strong law firm month-end close process solves that problem. It creates a set routine for reviewing your books, reconciling accounts, checking trust activity, reviewing revenue and expenses, and producing accurate financial statements. Instead of waiting until tax season to find problems, you catch them every month while they are still easier to fix.

The Cheat Sheet

A strong month-end close should help your firm:

• Reconcile every operating, credit card, loan, and trust account.
• Complete required trust account reconciliations and investigate differences.
• Confirm revenue and expenses are recorded in the correct period and accounts.
• Review accounts receivable, client balances, and cash flow.
• Produce clean financial statements that can be used for tax planning and business decisions.

The Business of Law: Your Books Need a Finish Line Every Month

Most law firms have money moving in several directions at once.

Clients pay retainers. Invoices are sent and collected. Earned fees may move from trust to operating. Vendors get paid. Payroll runs. Credit cards are used. Owners take distributions. Case expenses may be advanced and later reimbursed.

Your accounting system is trying to organize all of that activity.

But simply recording transactions is not the same as closing the books.

The month-end close is the point where you stop and verify that the financial activity for the month is complete and accurate. Think of it as checking your work before you use the numbers to make decisions.

Without that process, a law firm owner may look at a profit and loss statement and assume the firm had a great month. But what if several expenses are missing? What if revenue was recorded incorrectly? What if a credit card balance was never reconciled? What if the trust account does not match the individual client ledgers?

Those details matter.

The IRS also emphasizes the importance of complete business records. Good records help a business monitor its progress, prepare financial statements, track deductible expenses, prepare tax returns, and support the amounts reported on those returns.

For law firms, there is another layer: clients trust money. Trust accounting has its own rules, records, and reconciliation requirements. For example, under current Florida Bar rules, lawyers subject to Florida’s trust accounting requirements must perform monthly trust bank reconciliations and compare reconciled trust account balances with the total of the individual trust ledgers.

That is why month-end close should not be treated as basic bookkeeping cleanup. It is part of your firm’s financial control system.

Reconcile Every Financial Account

Why It Matters:

The first step in a reliable month-end close is making sure your accounting records agree with outside records.

If QuickBooks says your operating account has $85,000 but the bank records tell a different story, you need to understand why before relying on your reports.

Bank reconciliation helps identify missing transactions, duplicated entries, bank fees, uncleared checks, deposits in transit, and other differences. The IRS recommends reconciling checking accounts each month so the bank statement, checkbook, and accounting records agree.

How It Works:

At the end of each month, reconcile:

• Operating bank accounts
• Business savings accounts
• Business credit cards
• Lines of credit
• Loan accounts
• Payroll clearing accounts, when applicable
• Trust accounts

During the reconciliation, look beyond whether the ending balance matches. Review old outstanding checks, deposits that have not cleared, duplicate transactions, unexplained transfers, and unusual adjustments.

A reconciliation that technically reaches zero can still contain errors if transactions were forced, deleted, duplicated, or posted incorrectly.

CPA Pro Tip:

Do not let unreconciled accounts roll forward for months. One small difference can turn into a much larger cleanup project later.

If an account will not reconcile, find the cause instead of posting a random adjustment just to make the numbers match. A clean reconciliation should explain the difference, not hide it.

Complete Your Trust Account Reconciliation

Why It Matters:

For firms holding client funds, trust accounting deserves its own step in the month-end close.

Client trust money is not the firm’s money. Your accounting process needs to keep those funds separate and maintain records showing which client or matter owns each balance.

For Florida attorneys subject to Florida’s trust accounting rules, monthly procedures include reconciling each trust bank account and comparing the total reconciled trust balances with the total of the individual client or matter ledger balances. Differences must be specifically described and explained.

This is often called a three-way reconciliation.

How It Works:

At month-end, compare three pieces of information:

1. The bank balance after adjusting for items such as outstanding checks and deposits in transit.
2. The trust accounting or book balance showing the total amount recorded in the trust account.
3. The client ledger total showing how much is being held for every individual client or matter.

Those numbers should agree.

Your review should also look for:

• Negative client balances
• Old or inactive client balances
• Unidentified deposits
• Outstanding checks that have not cleared
• Transfers between trust and operating
• Earned fees that have not been properly moved
• Transactions assigned to the wrong client or matter
• Bank charges or fees affecting the trust account

Florida’s current rules also require specific trust accounting records and generally require applicable trust account records to be retained for six years after the final conclusion of the representation.

Other states may have different requirements, so firms should always follow the trust accounting rules that apply in their jurisdiction.

CPA Pro Tip:

Do not treat trust reconciliation as something to fix at year-end.

If a $500 difference appears in January and you wait until December to investigate it, you may have hundreds or thousands of transactions to search through. If you investigate it during January’s close, the transaction is still fresh and much easier to trace.

For firms using Clio and QuickBooks Online, your systems should also have a clear purpose. Clio can help track client and matter activity, while QuickBooks handles the firm’s broader financial accounting. The workflow between the two should be consistent so information is not being entered differently from month to month.

Review Revenue, Expenses, and the Balance Sheet

Why It Matters:

Reconciling the bank tells you that transactions are accounted for. It does not automatically tell you they were categorized correctly.

A $10,000 payment can exist in the books and still be recorded in the wrong place.

That is why the next part of the law firm month-end close process is reviewing what happened financially during the month.

How It Works:

Start with the profit and loss statement.

Review:

• Total revenue
• Revenue by practice area, when tracked
• Payroll and employee costs
• Contractor expenses
• Marketing expenses
• Software and technology
• Rent and occupancy costs
• Professional fees
• Case-related costs
• Other major operating expenses

Compare the current month with prior months and, when available, your budget.

You are looking for numbers that do not make sense.

If software expense is normally $2,000 per month and suddenly shows $9,000, investigate it. If revenue increased 30% but cash did not, find out why. If payroll increased but revenue stayed flat, understand what that means for your margins.

Then review the balance sheet.

Pay attention to:

• Bank balances
• Accounts receivable
• Credit card balances
• Loans
• Payroll liabilities
• Owner distributions or draws
• Fixed assets
• Trust-related balances
• Other assets or liabilities that have changed significantly

The balance sheet is often overlooked by business owners, but it can reveal problems that never appear clearly on the profit and loss statement.

CPA Pro Tip:

Do not review financial statements by asking only, “Did we make money?”

Ask better questions.

Why did revenue change? Why did payroll increase? Are we collecting what we bill? Are expenses growing faster than revenue? Is cash increasing with profit?

Your financial statements become useful when you start using them to explain what is happening inside the firm.

Review Accounts Receivable and Client Activity

Why It Matters:

Revenue on a report does not always mean cash in the bank.

A law firm can bill $150,000 in one month and still struggle with cash flow if clients are not paying those invoices.

That is why accounts receivable should be part of the monthly close.

How It Works:

Review your accounts receivable aging report and identify:

• Total outstanding receivables
• Invoices over 30 days old
• Invoices over 60 days old
• Invoices over 90 days old
• Large unpaid client balances
• Clients who repeatedly pay late
• Matters with significant work performed but limited collections

Then compare billing with collections.

For example, suppose your firm billed $120,000 this month but collected only $82,000. Your profit and loss statement may still appear strong depending on your accounting method and timing, but your bank account tells a different story.

That gap needs attention.

Your month-end process should also identify work that has been completed but has not yet been billed. If time entries are sitting unfinished or invoices have not been sent, the firm may be creating its own cash flow problem.

CPA Pro Tip:

Create a clear collection process before receivables become a problem.

Decide who reviews aging, who follows up with clients, when reminders are sent, and when an attorney needs to become involved. Month-end reporting can identify the problem, but someone still needs to own the next step.

Close the Books and Produce Your Financial Reports

Why It Matters:

Once the accounts have been reconciled and the activity has been reviewed, the month should have a clear finish line.

You should not continue making routine changes to a prior month after financial statements have already been reviewed. Otherwise, the report you looked at on the 10th could be different from the report you pull on the 25th.

That makes comparison and decision-making much harder.

How It Works:

Before finalizing the month, confirm that:

• Bank and credit card accounts are reconciled.
• Trust reconciliations are complete.
• Revenue has been reviewed.
• Expenses have been categorized.
• Loan and liability balances are reasonable.
• Payroll activity has been recorded correctly.
• Owner transactions are classified properly.
• Accounts receivable has been reviewed.
• Significant unusual transactions have been investigated.
• Required adjusting entries have been posted.

Then produce your monthly reporting package.

At a minimum, most law firm owners should regularly review:

• Profit and loss statement
• Balance sheet
• Cash flow information
• Accounts receivable aging
• Trust reconciliation reports, when applicable

Closing the books is only useful if you know what to do with the reports afterward. Once your month-end close is complete, take time to understand what the numbers are telling you. Our guide to The 5 Monthly Financial Reports Every Law Firm Owner Should Review breaks down the key reports and what law firm owners should look for each month. 

Depending on the firm, you may also track practice area profitability, attorney productivity, realization, collection rates, payroll as a percentage of revenue, or other key performance indicators.

Once the reports are final, lock or close the accounting period when appropriate so prior activity is not accidentally changed.

CPA Pro Tip:

Set a deadline for your close.

A financial report received two months after the fact is history, not management information. Your goal should be a repeatable schedule that gives leadership accurate information soon enough to act on it.

The exact timeline will depend on the size and complexity of your firm, but consistency matters more than chasing an unrealistic close date.

Use the Close for Tax Planning and Business Decisions

Why It Matters:

The month-end close should not end when the reports are generated.

Clean monthly books create the foundation for better tax planning and better business decisions.

If your books are several months behind, proactive tax planning becomes much harder. Your CPA may be trying to estimate annual income using incomplete information instead of working from reliable year-to-date results.

How It Works:

Once the month is closed, use your reports to ask questions such as:

• Is the firm on pace to meet its revenue goal?
• Is profit increasing with revenue?
• Are payroll costs sustainable?
• Are owner distributions reasonable based on cash flow?
• Are estimated tax payments still appropriate?
• Are there major purchases planned?
• Is the firm building enough cash reserves?
• Is one practice area more profitable than another?
• Does the firm have enough cash for upcoming tax payments?

This becomes especially important for high-earning law firm owners.

Tax planning often depends on timing. Decisions involving retirement contributions, equipment purchases, compensation, entity structure, estimated payments, and other strategies may have deadlines or work best when addressed before year-end.

Accurate monthly numbers give you more time to plan.

CPA Pro Tip:

Tax planning should not begin with, “What can we do in December?”

The better question is, “What are our numbers telling us throughout the year?”

When your books are closed consistently, your CPA can identify trends earlier and help you make decisions while you still have options.

Commonly Missed Items in a Law Firm Month-End Close

A month-end close can technically be completed while still missing information that matters.

These smaller items are often where we find problems or missed opportunities.

Old Outstanding Checks

A check that has been outstanding for several months should not simply remain on the reconciliation forever. Find out whether it needs to be reissued, voided, or otherwise addressed based on the circumstances and applicable rules.

Owner Transactions

Personal expenses, owner distributions, contributions, and reimbursements can easily be categorized incorrectly. Review them every month so they do not distort the firm’s operating expenses or taxable income.

Loan Balances

Loan payments often include both principal and interest. Posting the entire payment as an expense can make your profit and loss statement inaccurate and leave the balance sheet wrong.

Fixed Asset Purchases

Large equipment, furniture, or technology purchases may need different accounting treatment than routine office expenses. Flag significant purchases for review rather than automatically categorizing everything as an expense.

Duplicate Software and Recurring Expenses

Law firms often add software as they grow. Month-end is a good time to notice recurring subscriptions that are no longer being used or duplicate tools that could be eliminated.

Unbilled Work

You cannot collect an invoice that was never sent.

Review incomplete time entries, draft bills, and work that should have been invoiced. Small delays in billing can create large cash flow problems when they happen across dozens of matters.

Trust Balances That Never Move

Old client trust balances deserve attention. A balance that has been sitting untouched for months should be researched rather than ignored. The correct action will depend on the facts of the matter and the applicable bar rules.

These issues may seem small, but that is exactly why they are easy to miss. A good close process gives your team a regular opportunity to catch them.

Frequently Asked Questions

The Bottom Line: Build a Process You Can Repeat

The best law firm month-end close process is not the most complicated one. It is the one your firm can complete accurately and consistently every month.

That means reconciling accounts, reviewing trust activity, checking revenue and expenses, monitoring receivables, producing financial statements, and actually using those reports to make decisions.

Systems beat guesswork.

When your books are current, you do not have to wonder whether the firm can afford another hire, whether collections are falling behind, or whether a strong bank balance actually represents healthy profit. You have numbers you can trust.

Clean monthly accounting also makes proactive tax strategy possible. Instead of discovering your tax position after the year is over, you and your CPA can monitor profitability throughout the year and make decisions while there is still time to act.

For a growing law firm, that financial clarity becomes increasingly important. More attorneys, more clients, more transactions, and more revenue also create more opportunities for errors and inefficiencies.

Your accounting process should grow with your firm.
