Marketing has three kinds of outside help, and buyers confuse them. An agency executes: it runs the ads, writes the content, builds the site. A consultant advises: it produces a strategy, an audit or a brand study. A fractional CMO leads: it owns the plan and the people who carry it out. This page is about the second and third.
What a marketing consultant delivers
A consultant is hired for a deliverable with an end date. Typical projects are a marketing audit, a positioning and messaging framework, a go-to-market plan for a new product, a pricing study, customer research or a review of the agency roster. Fees are fixed or hourly; a solid audit with a 90-day plan runs roughly $8,000 to $25,000, and positioning work with customer interviews $10,000 to $40,000. When the deck is delivered, the engagement ends.
What a fractional CMO owns
A fractional CMO is hired for the outcome the deck describes. They own the marketing plan and update it as results come in. They hold the budget and move money between channels. They brief, review and replace agencies. They report pipeline and cost per acquisition to the CEO every month and answer for the number. Retainers run about $4,000 to $15,000 a month, and engagements run a year or more.
Who signs off
The difference that matters most in practice is decision rights. A consultant’s recommendation goes to the CEO, who decides whether to act and who will do the acting. In many companies the strategy sits in a shared folder because nobody owned the follow-through.
A fractional CMO decides within the budget and authority the CEO delegates. They can cancel an agency contract, approve a campaign, hire a freelancer or shift $20,000 from paid social to events without a meeting. Write those limits into the agreement: the budget the CMO controls, the vendors they can hire and fire, and what needs the CEO’s approval.
When a consultant is enough
A consultant is enough when you have someone to carry out the work. A company with a capable marketing manager who lacks a strategy can buy a strategy and execute it. A company launching one product into one new market can buy a go-to-market plan. A company that needs an outside view before a big decision, such as a rebrand or an agency change, can buy that view.
When you need a fractional CMO
You need a fractional CMO when the problem is ownership. Signs: you have bought two strategies in three years and implemented neither; your agencies report to the founder, who does not have time to manage them; nobody can say which channel produced last quarter’s customers; or the marketing manager keeps asking what to prioritize.
Watch for agency-owned CMOs
Some agencies sell a fractional CMO as part of a retainer. That can work, but the CMO’s employer also sells the execution, which affects how objectively they judge it. Ask whether the CMO will recommend cutting their own firm’s services if the numbers say so, and look for fractional CMOs who manage agencies they do not own.
A common path
Many engagements start as a consulting project, usually an audit, and convert to a fractional retainer when the founder decides they want the auditor to run the plan. If you expect that, agree the retainer price before the audit starts.
