How to Set and Track Key Performance Indicators in a Law Firm

May 18

9 min read

Law firm KPIs are the small set of measures by which a firm judges whether it is performing as intended: whether fee earners are producing billable work, whether that work is being invoiced and collected, whether matters are profitable, and whether clients are satisfied and returning. Most firms already collect some of this information, usually as a by-product of billing. Few have decided which measures matter, how each is defined, who is accountable for it and how often it is reviewed. The result is a monthly report that is read once, discussed briefly and not acted on.

A key performance indicator is useful only if it is tied to a decision. A measure that no one could act on, however interesting, is an observation rather than an indicator. A sole practitioner deciding whether to hire a paralegal, a partnership deciding whether a practice area justifies its overheads, and a managing partner deciding which clients to pursue for overdue invoices all need different measures, and a firm that tracks thirty indicators will normally give each too little attention to change anything.

This article sets out a method for choosing, defining and tracking law firm KPIs. It covers the principles of selection, the core financial and operational measures with their formulae, the client and people measures that complete the picture, the data discipline on which every measure depends, and a review rhythm. It does not provide benchmarks, because the appropriate level for any measure depends on the firm's practice areas, billing model, staffing and jurisdiction, and published averages of uncertain origin are more likely to mislead than to guide. The firm should establish its own baseline and measure improvement against it.

Principles for selecting law firm KPIs

Four principles keep a KPI framework manageable and useful.

Begin with the firm's objectives. If the firm's aim for the year is to improve cash flow, the emphasis will fall on billing speed and collection. If it is to expand a practice area, the measures will concern pipeline, matter acquisition and profitability of the new work.
Limit the number. Eight to twelve indicators, reviewed regularly, are more effective than a long list. Each should have a single owner.
Define each measure in writing. Without a precise definition, two partners will calculate "utilisation" differently and argue about the result rather than the cause.
Distinguish leading from lagging indicators. Revenue and profit are lagging; they report what has happened. Time recorded within a day of the work, number of enquiries converted to instructions and the age of unbilled work are leading, in that they signal what is likely to happen to revenue.

Core financial KPIs

The following measures form the backbone of most frameworks. Each is stated with its formula, so that the firm can adopt it consistently.

Utilisation

Utilisation measures how much of a fee earner's available time is recorded as chargeable. A common formula is chargeable hours recorded divided by available hours, where available hours are the contractual working hours less agreed leave, public holidays and any other defined exclusions. The firm must decide whether the denominator is standard hours or an adjusted figure, and must apply that choice consistently. Utilisation by itself says nothing about whether the time was billed or paid for; a fee earner with high utilisation and poor realisation is producing work that the firm is not earning from.

Realisation

Realisation compares the value of time recorded, at standard rates, with the value ultimately billed and collected. It is usefully divided into three stages.

Billing realisation: the value invoiced divided by the standard value of time recorded. A shortfall indicates write-downs before billing, discounts or fixed fee arrangements that undervalue the work.
Collection realisation: the value of cash received divided by the value invoiced. A shortfall indicates write-offs after billing, unpaid invoices or disputes.
Overall realisation: the product of the two, or equivalently cash received divided by the standard value of time recorded.

Separating the stages shows where value is lost. A firm that records its time promptly and invoices at full value, but collects poorly, has a different problem from one that discounts heavily at the billing stage.

Lock-up: work in progress and debtor days

Lock-up is the period during which the firm has done the work but not yet been paid. It has two components. Work in progress days measures the age of unbilled time and disbursements, calculated as the value of unbilled work divided by the value billed over a chosen period, multiplied by the number of days in that period. Debtor days measures the age of unpaid invoices by the same logic applied to receivables. The sum of the two is the firm's lock-up, and every day of reduction releases cash. For a small firm without large reserves, lock-up is frequently the most consequential measure in the framework.

Matter profitability

Matter profitability compares the fees collected on a matter with the cost of the time spent on it, valued at an internal cost rate rather than a billing rate. The calculation requires a reliable internal cost rate for each fee earner, derived from salary or drawings, overheads and expected hours. It is the measure most capable of changing behaviour, because it reveals that a fixed fee matter which appeared attractive at the time of quotation consumed far more time than the fee supported. The firm should compute it for each matter type rather than only for individual matters, so that pricing decisions are informed by a pattern.

An illustrative worked example

The following figures are illustrative arithmetic only, selected to show how the formulae operate. They are not market data, are not benchmarks, and should not be read as a target for any firm.

Suppose a fee earner has 1,600 available hours in a year and records 1,000 chargeable hours. Utilisation is 1,000 divided by 1,600, or 62.5 per cent. At a standard rate of 100 per hour, the standard value of time recorded is 100,000. If the firm invoices 85,000 after write-downs, billing realisation is 85,000 divided by 100,000, or 85 per cent. If it collects 76,500 of the 85,000 invoiced, collection realisation is 90 per cent, and overall realisation is 76,500 divided by 100,000, or 76.5 per cent.

Now suppose that the same fee earner holds 20,000 of unbilled work at year end and 15,000 of unpaid invoices, and that the firm billed 85,000 over the 365 days. Work in progress days is 20,000 divided by 85,000 multiplied by 365, which is about 86 days. Debtor days is 15,000 divided by 85,000 multiplied by 365, which is about 64 days. Lock-up is therefore about 150 days. The point of the example is not the figures but the diagnostic: the fee earner is recording a respectable proportion of time, but loses about a quarter of its standard value between recording and cash, and waits about five months to be paid for it. Raising utilisation would be the wrong response; the effort belongs in billing practice and credit control.

Operational and client KPIs

Financial measures report outcomes. Operational and client measures explain them.

Measure	Definition	Why it matters
Time recording lag	Average days between work done and time entry	Late recording leads to under-recording and later write-offs
Billing cycle time	Days from matter milestone to invoice issued	Governs work in progress days
Enquiry conversion	Instructions accepted divided by enquiries received	Shows the effectiveness of intake and fee quotations
Matter turnaround	Days from instruction to completion by matter type	Indicates efficiency and sets client expectations
Client retention	Clients who instruct again within a defined period	Repeat work is typically cheaper to win than new work
Client concentration	Share of fees from the largest clients	Reveals dependence on a few relationships
Complaints and file reviews	Number of complaints and issues found on review	Quality and risk indicator
Overdue deadlines or limitation diary exceptions	Count of missed or near-missed critical dates	Risk indicator, with potential professional negligence implications

Client concentration and risk measures are often neglected because they do not appear in the billing report. A firm that derives most of its fees from one client is exposed in a way that a profit figure does not show, and a firm that does not track critical date exceptions will be informed of a problem only when a claim is intimated.

People measures

Staffing is the largest cost in most firms, and the framework should include at least a small number of people measures: the proportion of time spent by qualified staff on tasks that could be delegated, staff turnover, and leverage, meaning the ratio of fee earners to supervising attorneys-at-law. These must be handled with care and never used as a mechanical basis for assessing individuals. A lawyer who devotes time to training a junior colleague or to pro bono work will show lower utilisation, and the firm should decide expressly how such work is to be recognised.

Data discipline: the condition for reliable KPIs

Every indicator is only as reliable as the data that feeds it. Several common weaknesses undermine KPI frameworks and should be addressed before the numbers are trusted.

Inconsistent time recording, with some fee earners entering time daily and others at month end, distorts utilisation and prevents meaningful comparison.
Matters without a defined type, fee arrangement or responsible attorney cannot be analysed. The matter opening process should require these fields.
Rates and cost rates that have not been updated render profitability calculations unreliable.
Write-offs recorded without a reason cannot be analysed. A short list of reasons, such as client dispute, error, excess time or goodwill, makes the information usable.
Manual spreadsheets maintained outside the practice management system create competing versions of the truth.

It follows that the first step in any KPI project is often not to choose measures but to repair the processes that supply the data. A firm that cannot say reliably how many hours were recorded last month should not yet be arguing about a utilisation target.

Setting targets without false precision

A target should be derived from the firm's own history and objectives. The firm should compute the current baseline for each measure over at least a full financial year, identify the portion of any shortfall that is within the firm's control, and set a target that represents a realistic improvement over that baseline. Targets copied from a published survey or a conference presentation reflect a different firm in a different market, and may be unattainable or, worse, too undemanding.

Targets should also take account of the nature of the work. A litigation department with long cycles and lumpy billing will show higher lock-up than a conveyancing department with predictable completions. A single firm-wide target for each measure will either be too easy for one department or too hard for another, and departmental or matter-type targets are generally more useful.

Presenting and reviewing the results

A dashboard should be short enough to be read in a few minutes and should show each measure against the baseline and the target, with a simple indication of trend. Colour coding assists, but the underlying figures should always be available. A rhythm of review helps to convert information into action.

Weekly: time recording lag, unbilled work approaching billing thresholds and the oldest overdue invoices. This is a short working review conducted by the responsible partner or practice manager.
Monthly: utilisation, realisation, lock-up, enquiry conversion and matter turnaround, discussed in a management meeting, with each exception allocated an owner and a date.
Quarterly: matter profitability by type, client concentration, retention and risk indicators, with decisions on pricing, staffing and client selection.
Annually: a review of the framework itself, retiring measures that have not prompted any action and adding those that the firm now needs.

The meeting should record decisions rather than merely discuss numbers. If a measure is off target for several periods and no one has changed anything, either the measure is unimportant or the firm is not managing.

Avoiding the misuse of KPIs

Measures change behaviour, and not always as intended. A firm that rewards hours recorded may find that time is inflated or that work is prolonged. A firm that penalises write-offs may find that fee earners refuse to concede reasonable adjustments to clients, to the detriment of relationships. A firm that rewards speed of billing may find that invoices are issued without proper review. The professional obligations of attorneys-at-law, including those concerning the fairness of fees and the quality of service, must remain the governing constraint, and the framework should include quality and risk indicators precisely so that financial pressure does not displace them.

Confidentiality and employment considerations also apply. Individual performance data is personal data, and the firm should be clear with its staff about what is measured, why, who sees it and how it is used.

Practical next steps

State the firm's three main objectives for the coming year, in terms that can be tied to measures.
Select no more than ten indicators, with at least one each for productivity, cash, profitability, client and risk.
Write a definition for each, including its formula, its source data and its owner, and circulate it to partners and managers.
Audit the quality of time recording, matter opening data and write-off reasons, and correct the weaknesses before relying on the figures.
Compute a twelve month baseline for each measure and set targets as improvements on that baseline, by department where appropriate.
Establish the weekly, monthly and quarterly review rhythm, and record decisions and actions at each.
Review the framework annually and retire any measure that has not led to a decision.

How practice management software supports KPI tracking

Reliable indicators depend on time, billing, matter and client data being captured once, in the same place, with consistent fields. Legalytech provides matters, billing and reporting within a single practice management platform for law firms, so that the data on which these measures depend is held together rather than reconciled from separate spreadsheets.
