Fractional CMO vs marketing agency: which one does your business need?

/ 01The short answer

A marketing agency and a fractional CMO do different jobs. An agency is execution capacity and specialised knowledge: campaigns built, media bought, content produced, usually by channel specialists. A fractional CMO is senior leadership of the marketing function: strategy, budget, priorities, measurement, and direction of everyone doing the executing, agencies included.

So the comparison is not really “which is better”. It is “which job does my business need done”. A useful test: if you already have an agency and your frustration is that you cannot tell whether the money is working, hiring a second agency will not fix it. The missing layer is leadership, not more production. If instead you know exactly what needs doing and simply lack the hands to do it, an agency (or a freelancer) is exactly the right purchase.

Declared interest, as always: Codify is a fractional marketing leadership practice, so we sit on one side of this question. We also refer execution out to specialist agencies, so when we say a good agency is part of the answer, we mean it.

/ 02What a marketing agency is actually for

An agency gives you access to a team of specialists without hiring them full time: media buyers, SEO practitioners, designers, content producers, developers. Most businesses are unlikely to need, or be able to afford, full-time in-house roles to cover every channel, and that is why the agency model works so well. You get access to specialised knowledge (like SEO) without the full-time cost.

For most Australian SMEs that capability arrives as a monthly retainer, typically $3,000 to $10,000 a month depending on how many channels are covered, with larger multi-channel programs running well beyond that.

Good agencies are genuinely good at this. Execution quality, channel depth and production speed are things most businesses cannot easily build in-house, and do not need to. Marketing channels have fragmented to the point where few in-house teams, even good ones, can cover everything without agency support.

What an agency is not built to do is lead your marketing function. Three reasons, and three gaps that could be hurting your business.

They see a channel, not the business. An SEO agency thinks about search. A social agency thinks about social. Nobody inside the retainer is paid to ask whether the budget should move from one to the other, whether the pricing is right, whether the distribution strategy is right, or whether the proposition itself is the problem. Those are the questions that decide results, and they sit above every channel.

They are briefed, not accountable. An agency delivers what was asked for. If what was asked for was the wrong thing, the work can be executed beautifully and still do nothing for the business. The quality of an agency’s output is capped by the quality of the direction it receives, and in many SMEs nobody senior is providing that direction.

Their scope is communications. Marketing is product, pricing, distribution and communications. Agencies work in the last of the four. If your growth problem lives in the other three, no retainer will reach it.

/ 03What a fractional CMO is actually for

A fractional CMO is an experienced marketing executive who leads your marketing function part-time: typically two to eight days a month, at $4,000 to $16,000 a month in the Australian market. We have covered the pricing in detail in what a fractional CMO costs in Australia.

A fractional CMO is typically someone who has run marketing functions and sat on senior executive teams across multiple businesses, with tertiary qualifications in marketing behind them. The title is not protected, so check for both. Plenty of people offer marketing leadership without ever having carried it, and running a function is a different job from working in one.

The job is the leadership layer: setting the strategy and getting it in writing, sizing and allocating the budget, deciding what gets done and in what order, briefing and managing the doers (in-house team members and agencies), building measurement the owner can read, and answering to you for the result.

The output is different in kind from an agency’s. An agency’s output is work: campaigns, content, media. A fractional CMO’s output is decisions: what to do, what not to do, what to spend, how to know if it worked. Businesses generally do not lack work. They lack the decisions that make the work add up to something.

/ 04Side by side

The last two comparisons carry the most weight. Whoever holds the thinking holds the value. When an agency engagement ends, the strategy (such as it was) usually walks out the door inside the agency’s slide deck. Leadership done properly builds the system inside your business, where it stays.

/ 05The structural problem with agency-led marketing

Many SMEs run marketing with no senior marketer at all: the owner, the CEO or a marketing coordinator briefs an agency directly, and the agency effectively sets its own strategy. This is where “the agency is burning money and I cannot tell if it is working” comes from. Be precise about why it happens, because it is not usually the agency’s fault. It is the structure.

An agency paid to run a channel will recommend more of that channel. Not out of dishonesty, but because that is the tool they hold and the team they staff, and with more money in the channel they can usually get more of a result. The same structure also has agencies reporting on their own performance. However good the intent, that is a conflict of interest baked into the arrangement, and it is unfair on both parties: the owner cannot evaluate the work, and the agency cannot get the strategic direction that would let it do its best work.

The fix is not firing the agency. It is putting someone on your side of the table who can set the direction, brief them properly, and read the results independently. Agencies mostly do sharper work under a strong client-side brief, and the good ones will tell you exactly that.

/ 06When each is the right call

An agency (or freelancer) is the right call when:

• The strategy is genuinely settled and written down, and what is missing is hands
• The need is single-channel and specific: a website build, an SEO program, media buying
• Someone senior inside the business is directing marketing and can brief and evaluate the work
• The budget is under roughly $3,000 a month, at which point buying leadership makes little sense; put the money into one channel done well

A fractional CMO is the right call when:

• Nobody in the business can say what the marketing strategy is, in one sentence, out loud
• You are spending real money with an agency and cannot tell whether it is working
• Marketing activity keeps happening but revenue does not move
• You are about to make a big marketing decision (first hire, agency selection, budget jump) and want it made once, properly
• The board or your accountant has started asking marketing questions you cannot answer

Neither is the right call when the business is too small to fund either properly. Under about $2 million in revenue, most businesses are better served by a one-off strategy project or diagnostic than by any monthly retainer, ours included.

/ 07The combination that usually wins

For most businesses between $5 million and $100 million, the answer to “agency or fractional CMO” is eventually both, in the right order and the right roles: a fractional CMO owning strategy, budget and measurement, directing one or two specialist agencies who execute the channels they are best at.

The sequencing matters. Direction first, then execution. Buying execution before strategy means paying professionals to do the wrong things faster. It is also why we suggest being wary of any single provider offering to be both: to set the strategy, execute it, and mark their own results. However capable, that arrangement removes the independent layer whose whole point is to evaluate the work. Keep the referee and the players separate.

Run this way, the economics usually improve rather than worsen. A leadership layer at $7,600 a month routinely pays for itself out of the waste it removes from an unexamined retainer and an unallocated budget: channels that should never have been funded, spend that belonged elsewhere, work that was never going to move revenue.

/ 08The bottom line

Agencies sell execution. A fractional CMO sells direction. If you know what needs doing and need hands, hire the agency. If you cannot confidently say what your marketing is doing and why, no amount of execution will fix that, and the leadership layer comes first. And if you already have both layers, keep them separate: the person setting the strategy and reading the results should not be the one selling you the execution.
