Hiring a fractional Head of Amazon is a different kind of decision than hiring an agency or a freelancer. You're not buying execution hours — you're handing one person accountability for your Amazon P&L. Get it right and you get senior judgment without a $300K salary. Get it wrong and you've given a stranger the keys to your biggest channel.
I'll be upfront: I run a fractional Amazon practice, so I have a horse in this race. But that also means I know exactly how these engagements go sideways — and the questions that separate a real operator from someone with a nice deck. This is the guide I'd want a friend to read before hiring anyone, including me.
Here's how to vet a fractional Head of Amazon without getting burned.
What Actually Matters (and What Doesn't)
Most brands vet on the wrong things — years in business, a slick portfolio, a big client logo wall. Those are proxies. The four things that actually predict whether a fractional Head of Amazon will move your P&L are more specific.
What matters less than you'd think: total years in business, agency size, and how many services they list. A five-person operation with real P&L experience will out-think a fifty-person agency running templates. For the deeper distinction between models, see Amazon agency vs. consultant.
9 Questions to Ask Before You Hire
Take these into the first call. The answers — and how comfortably they're answered — tell you almost everything.
The best answer to question 4 is contribution margin, or at least TACoS — anyone anchoring only on ACoS is optimizing a vanity metric. If you want to understand why, we broke it down in why your TACoS is lying to you.
Red Flags That Should End the Conversation
Some answers aren't yellow flags to note — they're reasons to hang up.
What It Should Cost
A fractional Head of Amazon typically runs $5,000-$25,000 per month, scaling with scope. A solo senior-strategy engagement — one leader owning direction and oversight — starts around $5,000/month. A leader-plus-team engagement, where execution is owned too, runs toward the top of the range. Either way, no percentage-of-ad-spend fees: those reward spending, not profit.
Put that against the alternative. A full-time Head of Amazon costs roughly $280,000-$340,000 fully loaded in year one once you add benefits, recruiting, and ramp — for one person's ceiling. The fractional route gives you senior leadership at a fraction of that, with no headcount risk. The cost logic mirrors the fractional CMO cost math, applied to Amazon specifically.
Before a full engagement, ask for a paid diagnostic or short trial. It's a low-risk way to see how someone actually thinks about your account. Brand GrowthIQ's Diagnostic is $3,000 flat, one-time, and rolls into your first retainer month if you continue — so you're not paying twice to test the fit.
Where to Find One
Three sources, in order of signal quality. Referrals from other brand operators are best — a warm reference from someone who's worked with the person beats any pitch. LinkedIn is next: it's where you can verify a candidate's actual work history against what they claim on a call. And Amazon's own Service Provider Network lists vetted account-management and advertising providers you can filter by reviews and specialty. Whatever the source, verify the background on LinkedIn before the first call.
Whichever channel you use, prioritize a named senior individual with real brand-side experience over a large agency or a general freelancer. The difference between "a fractional Amazon manager" and "the person who will own my P&L" is exactly the difference this guide is about — and it's covered further in what a fractional Amazon manager is and the fractional Head of Amazon overview.
Vet on the four things that matter, ask the nine questions, walk on the red flags, and you'll hire someone who owns the outcome — not someone who runs plays and reports on them. That's the whole difference between renting execution and hiring leadership.
FAQ
Start by defining the outcome you need owned — usually your Amazon P&L, advertising, and operations — then vet candidates on four things: real brand-side P&L experience (not just running ads), genuine Amazon depth (ideally ex-Amazon or ex-brand Head of Amazon), a capped client roster so you get senior attention, and verifiable references. Run a short paid Diagnostic or trial before a full engagement, and confirm the senior person — not a subordinate — will personally own your account.
Ask: Have you owned an Amazon P&L brand-side, and for which brand? How many clients do you take at once? Will you personally run my account or hand it to staff? How do you measure success — ACoS, TACoS, or contribution margin? Can you share two references from current or recent clients? What would you do in my first 30 and 90 days? What's your pricing and what's included? Reject anyone who promises guaranteed rankings or sales.
Expect $5,000-$25,000 per month depending on scope — a solo senior-strategy engagement starts around $5,000/month, while a leader-plus-team engagement runs higher. Compare that to a full-time Head of Amazon at roughly $280,000-$340,000 fully loaded in year one. Many providers also offer a paid diagnostic (Brand GrowthIQ's is $3,000 flat, one-time, and rolls into the first retainer month) so you can test the relationship before committing.
Walk away from anyone who guarantees rankings or sales, won't share references, is vague about who actually does the work, runs a large client roster (so you're one of many), reports only on ACoS while ignoring profit, or asks for your primary Seller Central password instead of delegated user permissions. Vagueness about scope and pricing is where overages and disappointment live.
The best sources are referrals from other brand operators, LinkedIn (where you can verify a candidate's actual work history), and Amazon's own vetted directory. Amazon's Service Provider Network lists qualified account-management and advertising providers you can filter by reviews and specialty. Prioritize a named senior individual with real brand-side experience over a large agency or a general freelancer.
Hire an agency when you need execution hours across many tasks and don't need a single owner of the P&L. Hire a fractional Head of Amazon when you want one senior leader accountable for strategy, profit, and results — coordinating execution rather than just delivering it. For $5M-$100M brands that have outgrown an agency but can't justify a full-time hire, the fractional leader is usually the better fit.
