💡 IN SHORT

A reliable month-end close for a law firm follows a repeatable sequence: capture all time and expenses, reconcile operating and trust bank accounts, complete three-way trust reconciliation, finalize billing, review AP and disbursements, post adjusting entries, and produce P&L, balance sheet, and cash flow statements. Done in a legal-specific system, the whole cycle compresses from days to hours.

📅 Why the Close Matters More for Law Firms

Most businesses close their books to understand profitability. Law firms close their books for that reason and to stay out of trouble. Trust accounting, client funds, and bar compliance mean a sloppy close is not just a management problem — it can become an ethics problem. A disciplined monthly rhythm protects both your margins and your license.

📊 Did You Know?

The longer your close takes, the staler your decisions. Firms that close within five business days can act on current-month profitability; firms that close three weeks late are always managing last month's firm.

✅ Step 1: Capture Every Hour and Cost

The close begins before the month even ends. Unrecorded time is unbilled revenue, and unrecorded costs erode realization. Confirm that all timekeepers have entered billable and non-billable activity, that hard and soft costs are logged against the right matters, and that any vendor disbursements are recorded.

💡 Pro Tip

AI-assisted time capture closes the single biggest leak in firm revenue: time that happened but never got written down. Capturing it during the month means there is nothing to chase at close.

🏦 Step 2: Reconcile Your Operating Account

Pull the bank statement and reconcile beginning balance, cleared deposits, cleared payments, and ending balance. Smart matching dramatically speeds this up — AI-powered reconciliation matches cleared transactions automatically and flags only the genuine exceptions for human review.

💰 Step 3: Complete Three-Way Trust Reconciliation

This is the step generic accounting software cannot do properly. For each trust account, reconcile the bank balance, the trust book balance, and the sum of every individual client ledger. All three must agree. Any difference is a problem to resolve before you close, not after.

🚫 Red Flag

If your client ledgers total more or less than your trust bank balance, stop. A negative client ledger means one client's funds are covering another's — commingling that no firm wants to explain to the bar.

🧾 Step 4: Finalize Billing

Run pre-bills, route them for attorney review, and release approved invoices. Whether you bill hourly, flat fee, contingency, or LEDES for corporate clients, finalize the month's invoices so revenue lands in the right period and AR aging stays accurate.

🧥 Step 5: Review Accounts Payable and Disbursements

Confirm vendor bills are entered and linked to the correct matters and GL accounts, approvals are complete, and any client-cost disbursements are recorded so they can be billed back. Unrecorded payables understate expenses and overstate profit.

📝 Step 6: Post Adjusting Entries

Record accruals, prepaids, depreciation, and any reclassifications using balanced, double-entry journal entries. A legal chart of accounts with a multi-level hierarchy keeps these entries clean and your reporting meaningful.

📈 Step 7: Produce and Review Financial Statements

Generate your trial balance to confirm debits equal credits, then produce the P&L, balance sheet, and cash flow statement. Review matter profitability and attorney performance while the numbers are fresh — that is where the close turns from a compliance chore into a management advantage.

📊 Did You Know?

When practice management and accounting share one system, your time entries, bills, costs, and trust activity already live in the ledger — so the close is mostly review and confirmation rather than re-keying data between disconnected tools.

✅ Key Takeaways

Capture all time and costs first — the close starts before month-end.
Reconcile operating and trust accounts, then complete three-way trust reconciliation before closing.
Finalize billing and review AP so revenue and expenses land in the correct period.
Post adjusting entries and confirm the trial balance before producing statements.
A unified, legal-specific platform compresses the close from days to hours and makes it audit-ready.
