Why QuickBooks trips up law firms

QuickBooks often organizes money in around Customers and money out around Vendors. A personal injury client does both: their settlement arrives in trust, then the firm pays their share back to them. The Customer and Vendor lists are not a trust ledger.

A settlement deposit is not the firm's revenue. Until properly disbursed, it is money owed to clients or other entitled parties. Record the trust bank asset and the matching Client Trust Liability. Only earned fees belong in firm income.

QuickBooks will record a payment even when the individual client's trust ledger would become negative. A positive pooled IOLTA bank balance does not mean this particular client's money is available. Check collected funds and the client ledger before release.

The universal setup

  1. Create the real IOLTA bank account in the chart of accounts. In QuickBooks Online, choose Bank and the Trust account detail type where available. Use a clear name such as IOLTA - Main. Keep operating funds in a separate bank account.
  2. Create Client Trust Liability as Other Current Liabilities. In Online, choose Trust Accounts - Liabilities where available. Desktop uses account types rather than the same Online detail-type menus. The total trust liability must equal the corresponding trust book bank balance.
  3. Create one Customer per client. Use a sub-customer, Project or Customer:Job for each matter when a client has multiple matters. Use the same client and matter identifier throughout the settlement.
  4. Create doctors, lien holders, referral attorneys and other third-party payees as Vendors. Pay the client's own share to the existing Customer on a Check or supported Expense form. Do not create a second Vendor record just to pay that client.
  5. Use Client Trust Liability on every trust deposit and payout line, with the correct Customer or matter on the line. Enable the Customer column where needed. The payment's header payee identifies the recipient; the line's Customer identifies whose money is being used.
  6. Load opening client balances from verified ledgers. Confirm that their sum equals the trust bank book balance. Do not invent an income deposit to make an opening difference disappear.
  7. Test one settlement before relying on the report. Record its deposit, doctor payment, client payment and earned-fee transfer. Confirm every trust line appears under the right client and that no client ledger goes below zero.

Two ways to track each client's funds

This guide recommends the Customer field on every trust transaction line. Here, Customer tag means the Customer or Customer:Job allocation field, not the separate QuickBooks Tags feature. One shared liability account avoids creating a new chart-of-accounts entry for every case.

A separate liability sub-account per client can work for a small practice with few open matters and a controlled chart of accounts. It is not a requirement to use both methods. Pick a policy with your accountant and make sure the resulting ledger has the required client and matter detail.

Record a settlement, line by line

Record the settlement deposit and confirm the funds are collected and available before writing any check against it. A bank feed entry or provisional bank credit is not proof that the deposit has cleared. Follow applicable trust rules and bank confirmation requirements.

The example trust deposit is $100,000. The $15,000 doctor payment, $50,000 client share and $35,000 earned fee total $100,000. The separate $500 operating case cost does not reduce that trust ledger. If the settlement authorizes reimbursement of a prior case-cost advance, record that separately with accountant-approved treatment.

An earned-fee payment reduces trust liability. The operating-side receipt then recognizes earned income or settles an existing receivable. Do not use a bare bank-to-bank Transfer as the whole entry: it does not by itself reduce the client's liability or explain the fee. Do not recognize the fee twice.

The Customer column is an allocation field, not a second payee. Use the client or matter on each category line, including a check payable to a Vendor. Use a Check or supported Expense form for the client's payout if a bill-payment workflow requires a Vendor. Check the report after posting.

Five core transactions. Example amounts belong to one illustrative settlement, not a customer result.

How to see each client's balance

Run Transaction Detail by Account. Filter Account or Distribution Account to Client Trust Liability, including its sub-accounts if used. Group by Customer, show the Customer or Customer:Job column, and include the matter identifier. Report menus vary by version and reporting view.

Use all dates through the reporting cutoff, or include a verified opening balance. A subtotal over only this month's activity is a change in balance, not necessarily the amount still held. On a liability report, credits increase the amount held and debits reduce it; check the report's sign convention with your accountant.

Each client's ending subtotal is what the firm still holds for that client. Separate matters when required. Review blank or Not specified groups, investigate negative balances, and confirm the sum equals Client Trust Liability and the trust bank book balance. Save the report with its filters and date basis.

Three-way reconciliation

Compare the adjusted bank balance, trust book balance and total client ledgers at the same cutoff date. A bank reconciliation alone is not the complete review.

Before you rely on the books

Ask the firm's accountant to review opening balances, the client-ledger report, earned-fee recognition and case-cost treatment. Confirm what happens to the Customer allocation when a bank-feed item is matched or a connector posts a payment. Test the actual configured transaction screens, not only a spreadsheet example.

Keep a record of the settlement statement, deposit clearance, approvals, payee instructions and disbursements. A software setting is not permission to release disputed or uncollected funds.

How Disbo helps

Keep QuickBooks. Add the matter-level controls.

Disbo prepares each disbursement from the settlement, pays each party by check or ACH from the firm's own trust account, and posts each line back to QuickBooks with the client tagged so the per-client report stays right. The firm prepares and approves the payment. Disbo does not hold the trust funds.

  • Overdraw guard

    Blocks a payout that exceeds the client's available trust balance in Disbo. QuickBooks alone does not provide that client-level block. Keep opening balances, external activity and connected records current.

  • Partial payouts and holds

    Pay undisputed amounts while retaining a documented hold for a disputed bill or another unresolved allocation. Release the remaining amount through a later approved payout.

  • Dual approval

    Separate preparation from release. Two-person approval is available for applicable IOLTA workflows, with payment approval records and two-factor authentication.

  • Case-cost checks

    Prepare case-cost payments from the proper operating-account workflow. Keep operating costs separate from client trust disbursements and associate the payment with the matter.

  • Payment status and notices

    Track payment status and send lien-holder payment emails without rebuilding a separate follow-up list. Status depends on the payment method and available bank or delivery records.

  • Monthly three-way reconciliation

    Bring matter-linked payment records and accounting records together for the monthly comparison of adjusted bank balance, trust books and client ledgers. The firm reviews and resolves differences.

Configuration boundary: Posting fields, client or matter mapping, approval options and reconciliation workflows depend on the connected QuickBooks version and the firm's configuration. Confirm the actual workflow during onboarding, especially for Desktop and Intuit Enterprise Suite. Do not assume a particular connector supports custom dimensions or every screen. Software supports the firm's process; it does not replace legal or accounting judgment.

Trust accounting rules vary by state, and QuickBooks setups vary by firm. Confirm your approach with your state bar rules and your accountant. This is educational content, not legal, tax, or accounting advice.
