Fractional CMO vs agency for owner-led businesses
An owner who wants more from the marketing can engage a marketing agency or a fractional CMO, and this guide compares the two.
The two are engaged for different work, and a business can use both. The guide states what each one is suited to, including the cases where an agency is the better choice.
Firefly sells the fractional CMO engagement, so we have an interest in this comparison. Every outside price in the guide is a published figure, and each one is listed with its source.
Our guide to in-house marketing vs an agency adds a third option, which is to hire an employee.
What this comparison covers
- What each one does
The first part describes each arrangement and who does the work.
- Fractional CMO vs agency, side by side
A table sets the two side by side on nine questions.
- What each one costs
Five published guides give price ranges, and each one is linked.
- When a marketing agency is the right choice
An agency fits a business whose plan is already clear.
- When a fractional CMO is the right choice
A fractional CMO fits a business where nobody leads the marketing.
1. What each one does
The rows describe each one, and the arrangement in which a business uses both.
- A marketing agency
- A marketing agency is an outside firm that carries out marketing work such as advertising, search, content, design and public relations. It employs specialists in each kind of work. The business describes what it wants in a brief, and the agency plans and produces the work within that brief.
- A fractional CMO
- A fractional CMO is a senior marketer who leads a company’s marketing for part of the week. The fractional CMO writes the marketing plan, decides how the budget is divided and directs the people who carry out the work. Those people are your staff, your agencies or both.
- The two together
- A business can engage both at the same time. In that arrangement the fractional CMO writes the plan and the brief, and the agency carries out the work.
A fractional CMO does the job of an in-house marketing director for fewer hours a week. Our guide to what a marketing director does describes that job.
2. Fractional CMO vs agency, side by side
The table compares the two on nine questions.
It describes the usual arrangement, and the contract of a particular agency may differ.
Fractional CMO and marketing agency
| Question | Fractional CMO | Marketing agency |
|---|---|---|
| What you buy | You buy the direction of the marketing. That covers the plan, the division of the budget and the supervision of the people who do the work. | You buy the marketing work itself, such as advertising campaigns, search work, content or design. |
| Who sets the plan | The fractional CMO writes the marketing plan and sets the order of its priorities. The owner sets the revenue targets. | The business sets the brief. The agency plans the work it is engaged for within that brief. |
| Who does the daily work | Your staff and your agencies do it, and the fractional CMO directs them. | The agency’s own staff do it. |
| Who works on the account | One senior person does the work of the engagement. At Firefly that person is Saad Afsar. | A team of the agency’s specialists works on the account, and each one handles a different kind of work. |
| What the report covers | A weekly report measures the marketing as a whole against revenue, using the figures in your own systems. | The agency reports on the work it is engaged for. |
| Hours | A standard engagement with Firefly is about five hours a week. | The hours depend on the scope of work agreed in the contract. |
| How you pay | You pay a monthly fee for the hours. Firefly charges $2,000 a month. | You pay a fee for the agreed scope of work. |
| Commitment | Firefly’s agreement is monthly, and the minimum term is three months. | The agency’s contract sets a term and a notice period, and both differ from one agency to the next. |
| The business it fits | It fits a business that has a marketing budget and people to do the work, and has no senior person who decides where the budget goes. | It fits a business that has a clear plan and needs a large amount of work carried out, or needs one specialist skill. |
3. What each one costs
The two fees pay for different work, so the two prices are not directly comparable.
The published figures in this part are ranges from five guides, and none of them is a quote.
- Published fractional CMO retainers
- A guide by Rick Ramos states that most fractional CMOs charge a retainer of $5,000 to $15,000 a month. A guide by Start Some Shift gives the same range for most engagements in the United States.
- Published agency fees
- Three guides to fractional CMO pricing also give a marketing agency’s monthly fee. MarkCMO lists $3,000 to $15,000 a month for each channel, such as search or paid advertising. MarketerHire gives $5,000 to $25,000 a month, and Geisheker lists $8,000 to $25,000 a month.
- Firefly’s fee
- Firefly charges $100 an hour. Its standard engagement is about five hours a week, which comes to $2,000 a month, and the minimum term is three months.
- The daily work is paid for separately
- A fractional CMO’s fee pays for the plan and the direction. The business also pays the people who carry out the daily work, whether they are its own staff or an agency.
Other guides give somewhat different ranges for a fractional CMO. Our page on what a fractional CMO costs lists each one with its source, and the published salary figures for a full-time CMO.

4. When a marketing agency is the right choice
A marketing agency is the better choice in three situations.
In each one the business needs work carried out and already knows what that work should be.
- A clear plan, and a large amount of work
- The business knows who its customers are and which channels reach them. It needs advertising run, content produced or search work done in volume. An agency has the specialists and the capacity for that work, and a fractional CMO who works about five hours a week does not.
- One specialist skill is missing
- The business needs search work, public relations or video production, and nobody on its staff does that work. An agency that specialises in the skill is the right choice.
- Tasks to carry out, and no wider plan to act on
- A business that only needs tasks carried out does not need a fractional CMO. That work is better given to an agency or to a marketing coordinator.
An owner in any of these situations can engage an agency directly, without a fractional CMO.
5. When a fractional CMO is the right choice
A fractional CMO is the better choice in three situations.
In each one the business has people to do the marketing work and no senior person directing them.
- Staff or agencies, and nobody directing them
- The business pays for marketing staff, for one or more agencies, or for both. No one senior decides how the budget is divided or answers for the result. A fractional CMO takes that role and gives the staff and the agencies one brief.
- The work does not fill a full-time role
- The business needs a senior marketer to set the plan and the budget, and that work does not fill forty hours a week. A fractional CMO does it in a few hours a week. A business that needs a marketing head present all week needs a full-time hire.
- The marketing head has left
- The role is empty while the owner replaces the person or decides whether to fill the role again. A fractional CMO can lead the marketing for a few hours a week during the gap.
Our page on the part-time interim CMO describes how Firefly covers a gap, and what a full-time interim executive would add.
A business with one location and a small marketing budget is usually too early for a fractional CMO. Our page Too early for a fractional CMO? lists five free things to do first.
Firefly’s fractional CMO engagement
The fractional CMO at Firefly is Saad Afsar. He writes the marketing plan, decides how the budget is divided and directs your staff and your agencies.
The engagement does not replace an agency. Saad directs the agencies you already use and judges their work by its results.
The work can start with a free audit. A senior marketer reviews how customers reach the business and sends back the three largest gaps within two business days, and our page on the marketing audit describes it.

Questions and answers
Is a fractional CMO better than a marketing agency?
Neither is better in every case, because the two are engaged for different work. An agency fits a business that has a clear plan and needs the work carried out. A fractional CMO fits a business that has people to do the work and no senior person directing them.
How much does a fractional CMO cost versus an agency?
Rick Ramos and Start Some Shift each give $5,000 to $15,000 a month for most fractional CMO retainers. Three published guides put a marketing agency’s fee between $3,000 and $25,000 a month. Firefly charges $2,000 a month for about five hours a week. The two fees pay for different work, so the prices are not directly comparable.
When should you hire an agency instead of a fractional CMO?
An agency is the right choice when the business has a clear plan and needs the work carried out in volume, or when it lacks one specialist skill such as search or public relations. An agency or a marketing coordinator is also the better choice for a business that only needs tasks carried out.
When is a fractional CMO the better choice?
A fractional CMO is the better choice when the business pays for staff or agencies and no senior person decides where the budget goes. It also fits a business whose marketing leadership does not fill a full-time role, and a business whose marketing head has left.
Can you use both a fractional CMO and an agency?
Yes, a business can engage both. In that arrangement the fractional CMO writes the plan and the brief, and the agency carries out the work. At Firefly, Saad Afsar directs the agencies a client already uses and judges their work by its results.
Who does the work in each arrangement?
In a fractional CMO engagement one senior person writes the plan and directs the work, and your staff and agencies do the daily work. In an agency engagement the agency’s own staff do the work, each in a specialist role.
