Law Firm Budgeting: Building a Twelve-Month Financial Plan

Jun 5

11 min read

A law firm budget is the written expression of what the principals expect the practice to earn, spend and retain over the coming year, together with the assumptions that support those expectations. Many small and medium-sized firms operate without one. They monitor the bank balance, pay bills when funds permit, and learn the true position when the annual accounts are prepared or the tax authority sends a demand. That approach tolerates good years and fails in lean ones, because a legal practice has an unusual financial profile: revenue is lumpy and delayed, costs are largely fixed, and the most valuable asset, the time of fee earners, perishes each day it is not billed.

A twelve-month plan converts these characteristics from hazards into variables that can be managed. It forces the firm to decide how many hours its fee earners can realistically bill, what it will charge for them, how long clients take to pay, which costs are committed and which are discretionary, and how much the principals can draw without starving the business. It also gives the firm a benchmark against which to compare actual results each month, so that deviations are noticed while there is still time to act.

This article describes how to build a law firm budget in a sequence of practical steps, with a worked illustration, a template of the principal lines, guidance on cash flow and client money, and a discipline for monthly review. The figures used are invented to demonstrate method and are not benchmarks. Firms should substitute their own data, and should take accounting and tax advice appropriate to their jurisdiction.

Why a law firm budget differs from an ordinary business budget

A budget for a manufacturing or retail business can be built around units sold and unit margins. A law firm sells time and judgement, and several features of that model shape the plan.

Revenue is capacity-constrained. A fee earner has a finite number of working hours. Revenue cannot exceed the product of available hours, the proportion that can be billed, the rate, and the proportion eventually collected. Growth therefore requires more people, higher rates, better utilisation or fixed-fee products with greater leverage.
There is a long gap between work and cash. Time is recorded, a bill is raised, the client considers it and pays. In litigation and transactional work this chain may take months. A firm can be profitable on paper and short of cash.
Costs precede revenue. Salaries, rent, insurance, regulatory fees and software subscriptions fall due regardless of whether the work has been billed.
Client money is not firm money. Funds held for clients, and in many jurisdictions money held on account of costs or disbursements, must be kept separate under the applicable accounting rules. A budget must never treat them as available working capital.
Partners are both owners and workers. The principals' drawings, and the notional salary for the work they do, are easily confused with profit, which distorts the picture of the firm's real performance.

Recognising these features at the outset prevents the commonest error, which is to project revenue as a smooth, steadily growing line when in practice it arrives in uneven pulses.

Step one: gather the baseline data for the law firm budget

A credible budget starts with the past twelve to twenty-four months of actual results. The firm should assemble the following material before making any projection.

Monthly profit and loss statements, or a reconstruction from the bank and ledger records if none were prepared.
A schedule of fees billed and fees collected by month, so that the true collection pattern can be seen.
Time records by fee earner, showing hours recorded, hours billed and hours written off or discounted.
A schedule of unbilled work in progress and outstanding invoices, aged by how long they have been unpaid.
A list of all recurring commitments, with renewal dates: premises, professional indemnity insurance, practising certificates and regulatory subscriptions, library and research services, software, telecommunications and loan repayments.
A record of the principals' drawings and of tax paid or accrued.

If the firm has not recorded time consistently, the first year of budgeting will rest on weaker data. That is itself an important finding, because it indicates where the firm needs to improve its records before it can plan properly.

Step two: model revenue from its drivers

The principal error in a legal budget is to enter a revenue total chosen because it feels achievable. A defensible revenue line is built from the following drivers for each fee earner.

The utilisation chain

Available hours. Start with the working days in the year, and deduct public holidays, planned leave, training and expected sickness. The result is the fee earner's available working time.
Target recorded hours. Not all available time can be spent on client work. Administration, business development, supervision and training consume a share, which differs substantially between a principal and a junior.
Billable proportion. Some recorded time will be written down or written off. The firm's own history is the only reliable guide to the realisation rate.
Billing rate. The expected average rate achieved, taking account of fixed-fee work, discounts and any rate increase planned for the year.
Collection rate. The proportion of billed fees that is paid, and when.

Illustrative arithmetic: one fee earner

The following is illustrative arithmetic only and is not market data. Assume a fee earner has 220 working days after holidays and leave, and works seven productive hours on an average day, giving 1,540 available hours. Assume the firm plans for 60 per cent of those hours to be recorded as client work, which gives 924 hours. If 90 per cent of recorded time is billed after write-downs, billed hours are 831.6. If the average realised rate is 100 currency units an hour, billed fees are 83,160 units. If 95 per cent of that is eventually collected, expected collections are 79,002 units. Changing any one assumption changes the answer in a predictable way: a five-point improvement in the proportion of hours recorded raises billed hours by roughly eight per cent, and a rate increase of ten units raises billed fees by ten per cent, provided that clients accept it.

The value of this exercise is not the final figure but the visibility of the assumptions. A principal who proposes a figure that requires 80 per cent of available time to be billed can see at once that it is aspirational rather than planned.

Separating types of work

Firms with a mixed practice should model each stream separately, because their patterns differ.

Hourly matters are modelled on the utilisation chain above.
Fixed-fee work, such as conveyancing completions, company incorporations and standard agreements, is modelled by volume multiplied by fee, with an adjustment for the time each unit actually consumes. If the fixed fee is not covering the time spent, the budget should expose that.
Retainer and subscription work provides predictable monthly income and should be shown as a distinct and relatively reliable line.
Contingency and success-fee matters, where permitted by the rules of the jurisdiction, should be budgeted conservatively and timed by reference to realistic hearing and settlement dates, since the income is uncertain and delayed.

It is prudent to treat unsigned or speculative work as upside rather than as budget. A pipeline list with an honest probability for each opportunity may be useful, but the budget should rest principally on instructions in hand and on recurring work.

Step three: classify and forecast costs

Costs in a law firm divide into those that are committed, those that vary with activity and those that are discretionary. A sound budget identifies each.

Fixed and committed costs

These include salaries and employer contributions for all staff, rent or the costs of premises, professional indemnity insurance, practising certificate and regulatory fees, accounting and audit fees where required, core software and telecommunications, and loan or lease repayments. They must be paid whether or not revenue arrives, and they constitute the firm's break-even obligation. A firm should calculate the monthly total of these costs and keep it visible, because it measures how much revenue must be collected each month for the firm to survive.

Variable costs

Some costs rise and fall with work. Court fees and similar disbursements are generally recoverable from clients, but they are paid first and recovered later, which affects cash flow. Counsel's fees, expert reports, travel, couriers, search fees and registry charges fall into this class. The budget should show disbursements gross, the expected recovery, and the timing of recovery, and should flag any category in which the firm habitually absorbs the cost.

Discretionary costs

Marketing, training beyond what is mandatory, office improvements, hardware replacement and some subscriptions can be deferred if revenue falls short. Separating them in the budget allows the principals to decide in advance which expenditure will be suspended if a trigger point is reached, rather than deciding under pressure.

Technology costs deserve particular scrutiny

Software expenditure has a tendency to accumulate in small subscriptions that are never reviewed. The firm should list every subscription, its cost, its renewal date and the person who uses it. Where pricing is per user, the cost grows with every addition to headcount, which should be modelled if hiring is planned. Pricing that is per firm with unlimited users makes the cost of adding a locum, a paralegal or an administrator predictable, which is a legitimate consideration when forecasting staffing changes.

Step four: construct the cash-flow forecast

A law firm budget that stops at the profit and loss account is incomplete. The cash-flow forecast translates billed fees into the months in which money is actually received, and shows whether the firm can pay its commitments as they fall due.

The simplest method is a monthly grid with the following lines.

Line	Basis of forecast
Opening cash (office account)	Closing balance of the previous month, excluding all client money
Collections from fees	Fees billed in earlier months, timed by the firm's actual average days to payment
Recoveries of disbursements	Amounts paid out earlier and billed to clients
Other receipts	Interest permitted to the firm, sundry income, capital introduced
Payroll and related costs	Contractual salaries, statutory contributions, bonuses when payable
Premises and overheads	Rent, utilities, insurance instalments, subscriptions on due dates
Disbursements paid	Court fees, counsel and other third-party costs
Tax and statutory payments	Income tax instalments, value added tax or equivalent where applicable, payroll taxes
Principals' drawings	Planned monthly amount, subject to the trigger rules below
Closing cash	Opening cash plus receipts less payments

Illustrative arithmetic: the effect of collection delay

The following is illustrative arithmetic and not market data. Suppose a firm bills 40,000 currency units each month, evenly, and its clients on average pay in 75 days, which is roughly two and a half months. At any moment the firm will have roughly 100,000 units tied up in unpaid invoices. If it can reduce the average to 45 days through earlier billing and firmer follow-up, the amount tied up falls to roughly 60,000 units, releasing around 40,000 units of working capital without a single additional hour being worked. This is why billing promptness and credit control belong in the budget as explicit assumptions.

Keeping client money out of the forecast

Money held in a client account, or paid on account of costs, belongs to the client or is held on trust until it is properly applied under the accounting rules of the relevant jurisdiction. It must not be used to fund overheads, even temporarily. The forecast should therefore be prepared for the office account only. Where a transfer of earned fees from the client account to the office account is permitted, it should appear as a receipt at the date it will properly occur. Practitioners should consult the accounting and trust-account rules of their own regulator for the permitted timing and documentation.

Step five: plan the principals' remuneration and tax

Principals' drawings are not an expense in the way that salaries are, but they are a call on the firm's cash and a source of recurrent tension. The budget should show them explicitly, and should distinguish between two different things: a notional salary for the work each principal does, which represents the cost of the labour that would otherwise have to be bought, and the residual profit, which is the return on the principals' capital and risk. A firm that reports a healthy profit before deducting any value for the principals' own work may be reporting something quite different from an economically sound business.

Tax must also be provided for. In many jurisdictions principals in partnership or sole practice are taxed on profits whether or not they have been withdrawn, and tax is payable in instalments or after the year end. If the budget omits a tax reserve, the demand will arrive when cash has already been spent. The firm should set aside a fixed proportion of monthly profit, determined with its accountant, into a separate tax account. Value added tax or its equivalent, where applicable, should likewise be treated as money collected for the revenue authority and not as income.

Drawings rules

A written rule prevents arguments. For example, the principals may agree to draw a fixed monthly amount and a further distribution only when the office account balance exceeds the next two months of committed costs plus the tax reserve. The precise formula should reflect the firm's own volatility, but the principle is that drawings follow cash, not billing.

Step six: build scenarios and trigger points

A single set of numbers assumes a single future. The practitioner knows that a large matter may settle early, that a major client may delay payment, or that a fee earner may leave. A budget is more useful if it contains three versions.

Base case. The expected outcome on realistic assumptions.
Downside case. Utilisation, realisation or collections materially below plan, with the effect on cash month by month.
Upside case. Additional instructions or faster payment, with the staffing and cost consequences that would follow, so that growth does not outrun capacity.

The point of the downside case is to establish trigger points in advance. For example, the firm may resolve that if the closing office-account balance falls below one month of committed costs, discretionary spending will be suspended and drawings reduced; and if it falls below half a month, the principals will review staffing and bank facilities. Decisions made calmly in advance are better than those made under strain.

Step seven: monthly variance review

A budget that is filed and forgotten has no value. Within the first two weeks of each month, the principals should review a one-page report comparing actual results with the budget.

Hours recorded and billed per fee earner against target, with explanations for material shortfalls.
Fees billed and fees collected against forecast.
Unbilled work in progress, and its age. Rising unbilled time is an early warning of delayed billing.
Aged debtors, listing every invoice unpaid beyond the firm's payment terms and the action taken.
Costs against budget, by category, with attention to disbursements paid but not yet recovered.
Closing cash and the forecast for the next three months, updated with what is now known.
Tax and statutory payments due in the coming quarter and the reserve held against them.

Many firms find that a rolling forecast works better than a fixed annual budget. At each month end the completed month is replaced by actual figures and a new month is added at the far end, so that the firm always looks twelve months ahead. The original budget remains as the benchmark, but the rolling forecast is the working document.

Common law firm budget errors

Treating billed fees as cash. A bill is a claim, not money. The cash-flow forecast should rely on collection history.
Ignoring write-offs. The gap between recorded time and billed time is a cost, and it is often largest on fixed-fee work and on matters taken on without a clear engagement letter.
Over-estimating principals' billable time. Principals spend substantial time on management, supervision and business development. Budgets that assume a principal bills at the level of a junior rarely survive contact with the year.
Forgetting step costs. A new hire is not merely a salary. It involves recruitment, equipment, supervision time, insurance and a ramp-up period before billing reaches target.
Neglecting seasonal and procedural patterns. Court vacations, holiday periods and the timing of regulatory renewals affect both revenue and costs.
Mixing client money with operating cash. This is both a budgeting error and, potentially, a serious professional breach.
Setting the budget once and not revisiting it. A plan that is not compared with reality teaches nothing.

Practical next steps

Collect the last twelve to twenty-four months of profit and loss statements, billing and collection data, and time records, and note any gaps in the records.
Calculate each fee earner's available hours and agree a target for recorded and billed time that the firm can defend with its own history.
List all committed costs with renewal dates, and compute the monthly break-even figure.
Build a month-by-month cash-flow grid for the office account only, timing collections by the firm's actual average days to payment.
Agree with the firm's accountant the tax reserve and the dates of statutory payments, and put them in the grid.
Write down a drawings rule and two or three trigger points for the downside case.
Prepare the one-page monthly variance report and diarise the review meeting for the first fortnight of each month.
Reassess the budget at mid-year and after any significant change in staffing, caseload or fee structure.

How practice management software supports financial planning

A budget depends on reliable time, billing and collection data, and those are most dependable when they are captured in the same system that manages matters and documents. Legalytech provides cloud practice management with time recording, billing and matter reporting, which allows a firm to obtain utilisation, unbilled work and outstanding invoices from its own records instead of reconstructing them each month for the review.
