Marketing Agency vs In House Team: What Should a Law Firm Do?

It depends on your revenue and how mature your marketing already is. Solo and small firms under roughly $2M usually cannot justify a full-time marketing hire and are better served by a focused agency or specialist vendors. Firms over $10M should build an internal department with agencies for specialized work. In the middle, where most law firms land, the best answer is usually a third one: a fractional layer that owns strategy, builds the attribution, and holds whatever vendors you use accountable to signed cases.

Key takeaways

• Under about $2M in revenue: use an agency or specialist vendors, not a full-time hire.
• $2M to $10M: a hybrid usually wins — a coordinator plus specialist vendors with senior oversight.
• Over $10M: build an internal department and use agencies for specialized campaigns.
• A full-time marketing director runs around $150,000 fully loaded. A CMO runs $250,000 to $380,000 or more in the first year.
• The third model is fractional: senior oversight for $5,000 to $15,000 a month, no salary, no recruiting risk.

The Real Cost of Building In House

The salary is only the start. A marketing director averages around $123,000 in base pay, and once you add benefits, payroll taxes, equipment, and software, the loaded cost lands closer to $147,000 to $160,000. A true CMO is a different bracket entirely, with base pay running $245,000 to $550,000 depending on market. Add benefits, recruiting fees of 15 to 25 percent of salary, a three to five month search, and a ramp period before they are productive, and the first year all in can reach $220,000 to $380,000 or more.

Then there is the risk nobody prices in. If the hire is wrong, you pay for the salary, the benefits, the severance, the lost months, and the cost of starting the search over. For a firm doing $3M in revenue, one senior marketing salary can eat 7 to 15 percent of gross revenue on a single person.

There is also a coverage problem. One hire, however good, rarely covers SEO, paid search, web development, content, and analytics at a high level. A marketing director who is excellent at content is probably not also running your paid search auctions. So you hire the person, and then you hire vendors anyway. Now you are paying for both.

The Real Cost of an Agency

An agency is leaner and faster to start, and a good one executes specialized work better than a generalist hire ever could. The catch is structural. An agency sits outside your firm, and it optimizes, naturally, for keeping your retainer — which is not always the same thing as driving down your cost per signed case. And when you run several vendors at once, say an SEO shop, a paid search shop, and a web team, nobody is coordinating them or holding the whole picture accountable to revenue. You end up with three competent vendors and no strategy connecting them.

Agencies are a strong answer when you have a validated channel and need expert execution. They are a weak answer when what you lack is the strategy and measurement that should sit above execution.

The Third Option

Between “rent an agency” and “hire a $300,000 executive” there is a model most firm owners have never had explained to them: fractional.

A fractional marketing leader works inside your firm part time — usually somewhere from 10 to 40 hours a month — for $5,000 to $15,000 a month. They sit on your side of the table. They set strategy before anyone spends a dollar, decide which channels deserve budget, build the attribution, choose and manage the vendors, evaluate whether your current agency is performing, and report cost per signed case in plain language you can act on.

Almost nobody promotes this model, and it has nothing to do with whether it works. The incentives are simply against it. Agencies do not push it because a fractional leader reduces their control over your account and asks harder questions. Recruiters do not push it because there is no placement fee on a fractional engagement. So the model that fits a huge share of firms between $1M and $10M stays quiet while owners get pitched the two options that pay other people better.

It is not worth it in every situation. If you are spending under about $5,000 a month on marketing with no real complexity, you do not need a strategy layer yet. You need to get the basics tracked and pick one or two channels. Fractional earns its keep when you have meaningful spend, multiple moving parts, and no clear line from any of it to signed cases. That describes a significant share of Arizona law firms doing between $2M and $10M in revenue right now — and it is the model DeVere Legal runs for firms in that position.

A Simple Way to Decide

Match the model to where your firm is right now.

• Under $2M in revenue: a focused agency or a couple of specialist vendors. A full-time hire does not pencil out yet.
• $2M to $10M: a hybrid. A junior coordinator inside the firm for day to day, specialist vendors for technical work, and a fractional layer above them to own strategy and accountability if the budget allows.
• Over $10M: start building an internal department, and keep agencies on hand for specialized campaigns and surge capacity.

The mistake I see most often is hiring the right thing at the wrong time. A solo firm spending $2,000 a month hiring a full-time marketer. A $5M firm with five disconnected vendors and nobody steering. The model matters far less than whether one person is on the hook for your cost per signed case.

What I Would Do First

Before you choose any of these, get attribution in place. Call tracking, GA4, and a CRM that tags every signed case back to its source. The order matters. Without that, you cannot evaluate an agency, you cannot brief an in-house hire, and you cannot tell a fractional leader where the money is leaking. Most firms try to pick a model first and figure out measurement later. That is backwards. Measure first, then decide who runs it. The decision gets a lot easier once you can see the numbers.

Frequently Asked Questions

Is a fractional CMO cheaper than an agency?

They solve different problems, so it is not a clean comparison. A fractional leader typically runs $5,000 to $15,000 a month for senior strategy and oversight. That is usually separate from the vendors and ad spend that handle execution. It does not replace an agency. It makes the money you already spend on agencies and ads trace cleanly to signed cases.

When should a law firm hire an in-house marketing person?

Generally once you are comfortably above $2M in revenue and have a validated channel that needs a dedicated owner. Below that, the loaded cost of a hire is hard to justify against what an agency or fractional model can do for less. Over $10M, a full internal department starts to make clear sense.

Can a small law firm afford a fractional CMO?

Sometimes, but it is not automatic. The model fits best when you are spending enough on marketing — often $5,000 a month or more — that the lack of strategy and measurement is actively costing you cases. If your spend and complexity are still small, put that money into tracking and one or two channels first.

What does a fractional CMO actually do?

They set strategy, choose and manage vendors, build the attribution that connects spend to signed cases, evaluate whether your current agency is performing, and translate marketing numbers into decisions the partners understand. What they do not do is sit in every internal meeting or handle daily execution. You are paying for senior judgment, not for hours you do not need.
