The recurring decision in multi-practice firm marketing is how much of a fixed budget each practice gets, and it is genuinely difficult rather than merely political. A practice billing hourly produces revenue that depends on matter scope. A flat fee practice produces a known amount per matter. A contingency practice produces nothing for years and then produces a great deal. A retainer practice produces recurring revenue. These are not comparable on cost per lead, cost per matter, or return on ad spend, and any single metric applied across them will systematically favor whichever practice happens to suit that metric. Meanwhile every partner believes their practice is underfunded, and without a framework the argument is settled by whoever is most persistent. This guide covers building the framework.

1Why Practices Cannot Be Compared Directly

• Revenue timing differs by years. One practice bills next month and another collects in three years, so any fixed reporting window favors the fast one.
• Revenue per matter varies by orders of magnitude. Counting matters treats a small transactional file and a major litigation as equivalent.
• Revenue certainty differs. A flat fee is known at engagement. An hourly matter depends on scope. A contingency matter may produce nothing.
• Attorney time per revenue dollar differs. A practice generating high revenue at high time cost may be less valuable than a lower-revenue practice that runs efficiently.
• Some practices produce recurring work. Ongoing matters and repeat engagements have lifetime value that a single-matter view misses entirely.
• Cost per lead comparisons are actively misleading. The cheapest leads almost always come from the lowest-value practice.

2Finding a Common Currency

Comparison requires converting each practice to something shared. The most workable is expected contribution per marketing dollar, calculated separately per practice and then compared.

1. Cost per qualified inquiry. What it costs to generate an inquiry the practice would actually want.
2. Conversion to engagement. What share of those become matters, which varies enormously across practices.
3. Expected revenue per matter. Average for that practice, with contingency practices requiring a probability-weighted figure.
4. Direct cost per matter. Attorney time at a realistic rate, plus any costs the firm fronts.
5. Expected contribution per marketing dollar. Multiply through, and now practices are comparable on one number.
6. Apply a timing discount. Revenue arriving in three years is worth less than revenue arriving next month, and making that explicit prevents endless argument about it.

The framework is imperfect and it is far better than the alternative, which is comparing incomparable metrics or deciding by seniority. Its main value is that it makes assumptions visible. When a partner disagrees with the allocation, they are arguing with a specific number rather than with a conclusion.

3The Allocation Model

• Start from the firm's practice classification. Growth, maintenance, strategic, constrained, and exit. Marketing allocation implements that decision rather than making it.
• Growth practices get majority share. Deliberately disproportionate, because that is what growth means.
• Maintenance practices get visibility budget only. Brand terms and local presence, not acquisition campaigns.
• Strategic practices funded on downstream value. If a practice feeds higher-value work, its own economics understate it, and that adjustment should be explicit.
• Constrained practices get nothing. Or brand defense only, until capacity changes.
• Reserve a firm-level allocation. Brand and recruiting funded from overhead so they do not compete with practice acquisition.
• Hold a contingency reserve. Ten to fifteen percent unallocated, for opportunities and for the partner request you will otherwise have to refuse.

4Capacity as a Hard Constraint

The fastest way to waste a firm's marketing budget is funding a practice that cannot take more work, and it happens constantly because capacity is invisible in marketing reporting.

• Capacity is attorney-specific, not firm-wide. A practice may have capacity in aggregate and none with the attorney clients actually want.
• Declined matters have a real cost. Intake time consumed, acquisition spend wasted, and a prospect who now has a poor impression of the firm.
• Review capacity monthly, allocate quarterly. Frequent enough to catch a practice filling up, stable enough to avoid constant reshuffling.
• Have a defined pause procedure. Which campaigns stop and how quickly, so a full practice can be throttled the same week rather than the next quarter.
• Hiring changes the allocation. A practice that just added an attorney should get budget before that attorney is underutilized.
• Consider referring out rather than declining. A referral relationship converts excess volume into something, subject to your state's fee division rules.
• Track declined matters by practice. The clearest evidence that budget is in the wrong place.

5The Partner Arbitration Problem

Every marketing plan at a multi-partner firm has to survive a room where each person has a practice they believe is underfunded. Plans that ignore this get undermined regardless of quality.

• Decide allocation as a partnership, in advance. Annually or semi-annually, with the practice classification agreed explicitly.
• Show the model, not just the conclusion. Assumptions visible so disagreement lands on inputs rather than on motives.
• Give every partner their own practice's numbers. Transparency removes the suspicion that another practice is being quietly favored.
• Name a single decision maker between reviews. With authority to decline requests, or the budget belongs to whoever asks most often.
• Use the reserve for genuine opportunities. Having something to allocate makes the decision maker's job possible.
• Document capacity constraints in writing. So reducing a practice's spend reads as operational rather than personal.
• Do not let monthly results trigger reallocation. Legal marketing is noisy month to month and reactive shifts destroy every practice's learning at once.

6Channel Selection by Practice

• Local Service Ads where the practice qualifies. Pay per lead with verification, and reported legal cost per lead commonly runs below standard search.
• Search for practices with existing demand. Anything people actively look for.
• Local visibility for practices searched on phones. Free traffic, though constrained by the profile category decision.
• Social direct response only where the practice suits it. Planning, transactional, and business matters rather than urgent or sensitive ones.
• Retargeting for practices with long consideration. Where a visitor is researching over weeks rather than deciding immediately.
• Brand and recruiting from firm overhead. Not from practice budgets.
• Do not run every channel for every practice. The most common source of waste in firm accounts.

7What Firm Budget Levels Support

The consistent error is spreading a modest budget across every practice, which funds none of them to a level that produces results. A firm with $3,000 monthly and five practices does better concentrating it on one than dividing it five ways, even though the latter feels fairer in the partner meeting.

8When and How to Reallocate

• Scheduled quarterly review is the default. With the model updated and the classification revisited.
• Capacity changes justify off-cycle moves. A practice filling up or an attorney joining are legitimate triggers.
• A single bad month does not. Legal marketing is noisy and monthly reactions destroy accumulated learning.
• Move budget in meaningful increments. Small adjustments produce no observable change and waste the disruption.
• Give changes a full quarter to read. Practices with long cycles need longer than that.
• Document what changed and why. So the next review has a record rather than recollection.
• Watch for permanent temporary moves. Budget shifted for a specific reason that stays shifted after the reason expires.

9Reporting That Settles Arguments

• Expected contribution per marketing dollar, by practice. The comparable number the whole model produces.
• Cost per engaged matter, by practice. Reported per practice and never averaged across them.
• Revenue from marketing-sourced matters, by practice. With the timing lag stated explicitly.
• Declined matters by practice and reason. The capacity evidence.
• Inquiry-to-engagement rate by practice. Where intake problems become visible.
• Allocation against plan. Whether the money actually went where the partnership decided it should.
• Firm-wide spend against firm-wide revenue, annually. The single blended figure worth keeping, as a check on everything else.
• Same format every period. So trends are legible and single months do not drive decisions.
