Our Discipline · 07 Sub-Disciplines
Legal Economics.
The Discipline Behind Every PlugLaw Engagement.
We don't apply marketing tactics or HR templates. We apply legal economics — the discipline of measuring and optimising the underlying unit economics of a law firm. Most consultancies don't name what they do. We name it because the discipline determines the result.
A Working Definition
Legal Economics Is What an Economist Would Do If They Ran Your Firm.
Every law firm has unit economics, the cost of acquiring a client, the cost of delivering a matter, the margin per practice area, the conversion rate of inquiries to retainers, the lifetime value of an average client, the break-even point on a senior hire.
Most firms do not measure any of these. They run on partner intuition and end-of-year P&L reviews. The intuition is often good. It is also often wrong, and the firm has no way to tell which.
Legal economics applies the discipline of management consulting and unit-economics analysis to the specific business of running a law firm. Not generic "consulting", a discipline with named sub-disciplines, repeatable measurement, and outcomes you can hold the analysis to.
The Seven Sub-Disciplines
What We Measure, and the Questions Each Measure Answers.
Different engagements lean on different sub-disciplines. Every engagement uses at least three.
- 01
Matter economics
What does it actually cost to deliver one matter?
Cost-to-serve per matter type, including unbilled time, partner attention, document overhead. Most firms know revenue per matter; almost none know true cost per matter, which is why low-margin work secretly subsidises the rest of the firm.
- 02
Pricing economics
Hourly, fixed, or subscription, and when does each pay?
When fixed-fee outperforms hourly. When subscriptions outperform both. When hourly is structurally superior. Most firms default to hourly because that is what they trained in, not because the math says so.
- 03
Practice-mix economics
Which practice areas earn their keep, and which subsidise others?
Margin by practice area. Cross-subsidy patterns. The 'flagship litigation that loses money to win the corporate' problem. We measure it by area, then either fix the loss-makers or kill them.
- 04
Capacity economics
How much of paid time is billable, and how much should it be?
Utilisation rates, billable conversion ratios, leverage (associates per partner). Most small firms run on assumed capacity rather than measured capacity. The gap is often 20–30% of available time.
- 05
Acquisition economics
What does each new client cost, and what is each one worth?
CAC by channel. LTV by client segment. Payback period. The metrics that determine whether marketing spend is an investment or a tax.
- 06
Hiring economics
When does a senior hire pay back, and when doesn't it?
The break-even matter count for a new associate, senior counsel, partner-track hire. The leverage that justifies a non-billable hire. The pattern of hires that quietly bleed the firm.
- 07
Geographic economics
Which markets reward expansion, and in what sequence?
Demand maps. Competitive density. Reputation transferability. The economics of opening city N+1, and the predictable failure patterns we see when firms get the sequence wrong.

A Worked Example
What an Audit Looks Like for a 5-Lawyer Firm.
CAC
₹12,400 $310
Cost per won matter
Within healthy range; LinkedIn outbound is undercutting Google Ads by 40%.
LTV
₹1.85 L $4,800
Avg client revenue, 24 months
Higher than expected, corporate retainers are quietly anchoring the book.
Utilisation
52% 52%
Billable hours / paid hours
Below the 65% benchmark for this size. Two associates have visible slack.
Margin / matter
38% 38%
After fully-loaded cost
Family-law mandates run at 12% margin and should be re-priced or referred out.
Illustrative. The actual audit covers all seven sub-disciplines and produces a one-page memo with three to five prioritised actions. Not a 60-page deck.
Why We Name It
Naming the Discipline Forces Accountability.
A "marketing consultancy" can declare success when the reports look pretty. A legal-economics practice has to defend specific numbers, CAC, LTV, payback, margin per practice area, that the partners can verify against their own books.
We name our discipline because the framing changes what the engagement gets evaluated against. You're not buying a deck. You're buying a measurable improvement in seven specific economic indicators of your firm.
And if those indicators don't move, we have nowhere to hide.
