Fractional CFO for Law Firms

A law firm is a business with unusually bad natural cash mechanics. Hourly work sits in WIP, then in AR, before it becomes money. Contingency work inverts the problem: the firm advances costs for months or years, then receives a spike. Meanwhile payroll, rent, and malpractice premiums arrive on schedule, and the partners, reasonably, want to be paid.

The CFO engagement covers the layer above the books: a rolling cash forecast that models those lags explicitly, a draw and distribution policy the forecast supports, compensation modeling when the partnership needs it, monthly reporting that shows performance by attorney and practice area, and the financial case for the firm's real decisions: the next associate, the lateral with a book, the office lease, the line of credit.

It runs on top of legal-specific bookkeeping, matter-level cost tracking, trust reconciliation, realization data, which our law firm bookkeeping service maintains when the firm does not already have it handled. For how the general fractional model works, engagement structure, cadence, and scope, see the fractional CFO services page. This page covers what changes when the client is a law firm.

The engagement usually earns its fee when several of these are true:

• The firm has 3 to 25 attorneys and more than one owner, so draws and comp require shared numbers, not one person's judgment.
• Partner draws swing with the bank balance, or a draw has ever been clawed back or skipped without warning.
• A contingency docket makes revenue arrive in spikes while costs advance steadily.
• The firm leans on a line of credit every year and cannot articulate exactly why.
• Compensation discussions have become annual arguments because origination and collection data lives in three systems and nobody trusts any of them.
• Growth decisions (an associate, a lateral, a second office) are being made on instinct because nobody has modeled them.

If the firm is a solo or two-attorney practice with steady hourly billing, start with clean books and a tax plan instead; our law firm tax planning service usually moves the needle more at that size.

A law firm forecast that starts from "last year plus growth" is useless, because legal revenue is two different machines wearing one P&L.

The hourly engine is forecast on lags. Hours recorded become WIP; WIP becomes bills on the firm's actual billing lag; bills become cash on each client group's actual payment behavior. The model carries those lags explicitly, so when the firm has a strong quarter of production, the forecast correctly shows the cash arriving a quarter later, and payroll in between is planned, not survived. It also prices realization honestly: hours written down before billing and bills discounted after are both leaks the forecast must reflect.

The contingency engine is forecast as a probability-weighted pipeline. Each significant case carries an expected fee range, an expected resolution window, and a probability set with the partners, refreshed quarterly. No single case lands as predicted; the portfolio curve is still the best available planning tool. Draws and case-cost budgets key off the conservative end of the curve, and any settlement above plan flows to reserves and distributions by a pre-agreed formula instead of by mood.

The two engines meet in a 13-week cash view plus a 12-month rolling forecast, with trust activity excluded entirely. Client funds in IOLTA are not firm money and never appear in the forecast as available cash; they enter the model only when fees are earned and properly transferred.

1. Lockup: the work-to-cash gap quietly finances the clients.

Between unbilled WIP and unpaid AR, an hourly firm routinely has three months of revenue parked in other people's accounts. The firm feels busy and looks profitable while the operating account thins. The CFO measures lockup in days, sets targets by practice area, and makes billing discipline a standing agenda item, because two weeks of lockup improvement releases more cash than most firms' annual profit growth.

2. Contingency lumpiness: eighteen months of costs, one deposit.

A contingency practice pays salaries, experts, and filing costs continuously and gets paid in occasional spikes. Firms that treat each settlement as spendable income ride a permanent feast-and-famine cycle, and the famine always arrives mid-case. The fix is structural: a smoothing reserve funded from every large fee, a case-cost budget treated as a real capital allocation, and draws set from the forecast rather than from the latest deposit.

3. Draws set by last year's best month.

Partner draws tend to ratchet: they rise after a good stretch and become politically impossible to lower. When draws exceed sustainable distributable cash, the gap gets financed by the line of credit, by stretched vendor payments, or by skipped estimated tax payments, three versions of the same mistake at increasing cost. A written draw policy, reviewed quarterly against the forecast, is the single highest-value document a small partnership can adopt.

Draw planning. The model starts from distributable cash: collections, minus operating costs, minus a working-capital floor, minus reserves for case costs and taxes. What remains is divided into a level monthly draw per partner set deliberately below the sustainable number, plus quarterly true-up distributions when actuals beat plan. Partners get predictable personal income; the firm gets a buffer that absorbs a slow quarter without drama; and estimated tax payments are planned from the same schedule instead of scrambled.

Origination comp modeling. When a partnership wants to move to, or repair, origination-based compensation, the CFO's contribution is neutrality and arithmetic. The model prices the proposed rules, origination percentages, splits on shared and inherited clients, sunset schedules for retiring partners, floors for working attorneys, against the firm's actual prior-year data, and shows each partner the number the formula would have paid them. Seeing the real payout table before the vote converts an emotional negotiation into a design discussion, and it surfaces the edge cases (the shared institutional client, the cross-sold matter) while they are still hypothetical.

Both models depend on data the billing system already contains but nobody has assembled: origination tags, working-attorney collections, and realization by partner. Assembling it once, correctly, is most of the work; after that the model updates monthly.

• Firm P&L, accrual and cash views, against budget, with variances explained.
• Production report: hours, billings, realization, and collections by attorney and practice area.
• Lockup report: WIP aging and AR aging, in dollars and days, with the ten largest stuck balances named.
• Contingency pipeline summary (where applicable): expected value by resolution window, case costs advanced to date, and movement since last month.
• Draw and distribution status: draws paid vs policy, distributable cash, and the quarterly true-up projection.
• Trust compliance confirmation: three-way reconciliation completed, exceptions listed (the target is a boring, empty list).
• 13-week cash forecast, flagging any week the operating account approaches its floor.

The pack is built to be read in twenty minutes and argued about for forty. The arguing is the point: it moves partner disagreement onto shared numbers.

Every metric is tracked by attorney and by practice area, not just firm-wide. Firm-wide averages are where a strong practice group subsidizes a weak one invisibly, sometimes for years.

Monthly. The reporting pack is delivered and reviewed: production, lockup, cash, and the draw status. Collection problems get owners and deadlines. Anything drifting, an associate under target, a client aging past 60 days, gets handled at one month, not at year-end.

Quarterly. The contingency pipeline is re-scored with the partners; draws are trued up against distributable cash; estimated tax planning for the partners is coordinated with the tax team from the same numbers. Hiring and pricing decisions, the next associate, the annual rate letter, get modeled here.

Annually. Budget, comp, and structure: next year's budget by practice area, the comp model refreshed with the year's actual data, rate increases priced against realization history, and the year-end handoff to the tax side, closed books, draw and distribution records by partner, and the capital account picture, so the firm's and partners' returns start from agreement rather than archaeology.

• A draw got skipped or clawed back. The moment partner income becomes unpredictable, the partnership wants a system, immediately.
• The comp conversation broke down. A partner vote on origination rules stalled because nobody trusted the data underneath the proposal.
• The contingency docket got serious. One or two potential seven-figure fees turned cash planning from a nuisance into a fiduciary matter.
• The line of credit stopped going to zero. What began as a bridge became a balance, and the bank started asking better questions than the firm could answer.
• A growth decision is pending. A lateral with a book, a merger conversation, or a second office needs a model, not a gut call.

For what the engagement should cost and how to compare proposals, see the fractional CFO cost guide. If the real question is whether to hire in-house instead, the fractional vs full-time CFO comparison covers that decision directly.

• Trust accounting done correctly: client funds segregated, three-way reconciliation monthly, and advanced fees held in trust until earned per the applicable state's rules.
• Matter-level cost tracking, so advanced case costs are recorded as what they are and recovered at resolution instead of leaking into overhead.
• Billing system data tied to the general ledger: production, realization, and collections reconciled to the books, monthly, so the KPI pack and the financials agree.
• A monthly close on a schedule, every account reconciled, because the forecast starts from verified balances.
• Partner equity and draw records maintained through the year, not reconstructed at tax time.

When this layer is missing or shaky, we scope cleanup first through our law firm bookkeeping service, then start the CFO cadence. Forecasts built on unreconciled legal books are not conservative or aggressive, they are fictional.

The mechanism is unglamorous: a probability-weighted pipeline, a reserve policy, and a written draw formula. Firms do not lack the intelligence for this; they lack a neutral party whose job is to hold the line when the big deposit lands and everyone has a boat in mind.
