The vital law-firm KPI is conversion of time into collected fees. Recorded hours reassure, but they do not fund the firm until invoiced and collected.
Executive Summary#
Realised hourly rate, utilisation, WIP, billing delay and collection should be read by team and matter type. Management must respect client relationship and legal-work quality.
Field Diagnostic#
| Situation | Risk | Evidence or control |
|---|---|---|
| WIP | time not converted | hours, matter phase, owner |
| Collection | cash delayed | aged receivables, reminders, disputes |
| Realised rate | fixed fee underpriced | collected fees / time |
Documents and Evidence to Gather#
- recorded time
- issued invoices
- customer ageing
- engagement letters
- disbursements by matter
Personalised Operating Method#
The review should start with WIP, because the identified risk is clear: time not converted. The evidence to produce is not a general comment but a verifiable item: hours, matter phase, owner. This first level prevents management from building a decision on commercial impressions or an overly aggregated accounting total.
The second point is Collection. Here, the risk is different: cash delayed. Management should therefore organise the file around aged receivables, reminders, disputes, then check that this evidence appears in accounts, cash and monthly reporting.
Finally, Realised rate must be isolated before closing. When fixed fee underpriced, management becomes fragile. The expected evidence, collected fees / time, turns a grey area into a documented decision.
Documentary Reading#
The most useful documents in this file are: recorded time, issued invoices, customer ageing, engagement letters, disbursements by matter. They should not only be archived; they should be reconciled with one another. An invoice without payment, a contract without flows, an export without bank matching or a decision without minutes is not enough to secure the position.
Leadership Arbitration#
Management should mainly retain three decisions: track WIP by partner, calculate realised hourly rate, create billing routine. These decisions give the firm a concrete roadmap and keep the topic from remaining an abstract recommendation.
Sector Case Study#
A firm believes it is saturated because schedules are full. Yet fixed fees consume more hours than planned and invoices go out late. The decisive KPI is WIP conversion into cash.
Our Chartered Accountant's View#
Hayot Expertise connects accounting and firm organisation. The dashboard should help choose between pricing, delegation and collection.
The Underestimated Risk#
The underestimated risk is the poorly priced fixed fee turning a good client relationship into negative margin.
What Leadership Must Decide#
- track WIP by partner
- calculate realised hourly rate
- create billing routine
- collect before critical ageing
2026 Watchpoints#
- separate disbursements
- monitor CARPA
- do not confuse hours and cash
- document client discounts

Frequently asked questions
How many KPIs should a law firm monitor?+
A few indicators read every month are better than a long dashboard. Useful KPIs trigger pricing, cost, hiring, collection or financing decisions.
law firm financial KPIs France: which source should be used?+
Use a reconciliable source: accounting, bank, invoices, payroll or business system. An unreconciled KPI quickly becomes decorative.
Is revenue enough as a KPI?+
No. It must be read with margin, cash, working capital and productivity. Uncollected or unprofitable growth can weaken the business.
How often should the dashboard be reviewed?+
Monthly in a stable business, more often when cash, inventory, jobs, matters or acquisition vary materially.
How does Hayot Expertise build a dashboard?+
We start from management decisions, then select reliable data. The dashboard must be short, actionable and reconciliable with accounts.
