Amazon agency vs freelancer vs in-house: how should sellers choose?
Below roughly £20k a month on Amazon, a freelancer or a one-off project usually returns more than a retainer. Between £20k and £150k, an agency generally wins on breadth of skill for the money. Above that, an in-house hire supported by specialists becomes the cheaper option per hour.
How do the three options actually compare?
| Criterion | Freelancer | Agency | In-house |
|---|---|---|---|
| Typical UK cost | £25–£75/hr, or £400–£1,200/mo | £750–£6,000/mo | £32k–£55k salary plus employer costs |
| Breadth of skill | One or two disciplines | All of them, at some depth | Whatever that person knows |
| Time to productive | Days | 2–4 weeks | 2–4 months including hiring |
| Key-person risk | High | Low | High |
| Institutional knowledge | Leaves with them | Leaves with them | Stays with you |
| Category experience | Variable | Across many accounts | Yours only |
| Exit cost | Low | Notice period | Redundancy |
When is a freelancer the right answer?
When the work is narrow, defined and finite. A freelance copywriter rewriting twelve listings is often better value than an agency doing the same job, because you are paying for one skill rather than a team.
Choose a freelancer if: you are under about £20k a month on Amazon, you know specifically what needs doing, you have someone internally who can brief and review, and you can tolerate the work stopping if that person becomes unavailable.
Avoid if: you need several disciplines at once, or if nobody in your business can tell good Amazon work from bad. A freelancer needs a competent client to be effective.
When does an agency make sense?
When you need four or five skills and cannot justify four or five hires. A retainer buys keyword research, copywriting, advertising, design direction and compliance monitoring from one contract.
Choose an agency if: you are between roughly £20k and £150k a month, advertising is running and needs weekly attention, you want one accountable party, and you value not carrying the recruitment risk.
Avoid if: your budget only stretches to the bottom of the market. Under about £500 a month you are usually buying one person managing many accounts to a template, and a good freelancer at the same price will do more.
When is in-house cheaper?
Later than most people think. A £40,000 salary is roughly £48,000 once employer National Insurance and pension are included — about £4,000 a month for one person's knowledge.
That is more than most agency retainers, and it buys one skill set rather than several. The advantage is that the knowledge stays in the business, which compounds.
Choose in-house if: Amazon is above roughly £150k a month, it is strategic rather than a channel, and you can give that person enough work to fill a week. Most in-house Amazon hires under that threshold end up doing something else half the time.
Is a hybrid better than any of the three?
Frequently, and it is the arrangement we see working best above about £100k a month: one in-house person who owns the account and the relationships, with specialist support bought in for advertising, listing rebuilds or launches.
The in-house person keeps the knowledge and the context. The specialists bring the pattern recognition that only comes from seeing many accounts. It costs more than either alone and usually returns more than both.
The split that works most often puts advertising and listing rebuilds outside and everything else inside, because those two are the most technical and the most time-hungry. Our PPC management and listing optimisation are sold separately for exactly this arrangement, and the pricing page shows what each costs on its own rather than only as part of a full retainer.
What are the failure modes of each option?
Each of the three fails in a predictable way, and knowing which failure you can least afford is often a better basis for the decision than the cost comparison.
| Option | How it usually fails | The early warning sign | What reduces the risk |
|---|---|---|---|
| Freelancer | Single point of failure — illness, a bigger client, or simply moving on | Replies slow down before the work does | Documented processes, and Brand Registry plus Amazon Ads in your own name, not theirs |
| Agency | The person who sold it is not the person doing it; the account drifts to a template | Reports become descriptions rather than decisions | Named people, a written scope, and a review point at ninety days |
| In-house | One person cannot cover keywords, copy, advertising, creative and compliance — see the seven disciplines | Advertising is tuned weekly, listings untouched for months | Buy in the specialisms the role cannot cover |
Two of these are cheap to insure against and worth doing in every case. Keep Seller Central, Amazon Ads and Brand Registry in your own company's name whoever runs them — there is more on why in what an Amazon agency actually does. And keep a written record of what changed and when, because that log is the only thing that survives a handover intact.
The third risk is the one nobody quotes for: the cost of a bad month going unnoticed. A freelancer on holiday and an agency mid-handover both look the same from the outside, which is a suppressed listing or a policy warning sitting unattended. Whatever you choose, make sure someone is named as responsible for account health notifications — that is the failure that turns expensive fastest, as the suspension guide sets out.
A decision guide by monthly revenue
| Monthly Amazon revenue | Usually the best fit | Why |
|---|---|---|
| Under £10k | One-off project, or DIY with tools | No ongoing fee can pay for itself at this base |
| £10k – £20k | Freelancer, or a small entry retainer | Narrow, well-defined work returns most |
| £20k – £75k | Agency retainer | Several disciplines needed at once; breadth wins |
| £75k – £150k | Agency, or first in-house hire plus specialists | Depends on whether Amazon is strategic for you |
| £150k+ | In-house team plus specialist support | Cheaper per hour and the knowledge compounds |
These are starting points, not rules. A complex catalogue at £30k a month can need more help than a simple one at £100k. If you want a read on your own account before deciding, the free audit will tell you which of the three we would actually recommend — including when the answer is none of them.
Questions people also ask
Is an Amazon agency better than a freelancer?
Not universally. A freelancer is better for narrow, well-defined work and for sellers under roughly £20k a month. An agency is better when several disciplines are needed at once — keyword research, copywriting, advertising and compliance — and you want one accountable party.
How much does an in-house Amazon manager cost in the UK?
A salary of roughly £32,000 to £55,000 depending on experience, which is about £38,000 to £66,000 once employer National Insurance and pension are included. That is more than most agency retainers, for one skill set rather than several.
At what revenue should I hire an Amazon agency?
Around £20k a month is where a retainer typically starts paying for itself, because the same percentage improvement is applied to a large enough base. Below roughly £10k a month, a one-off project usually returns more than any ongoing fee.
Can I do Amazon marketing myself?
Yes, and plenty of sellers do it well up to a point. The constraint is usually time rather than knowledge. Free tools handle the calculations; what an agency adds is the weekly attention and the pattern recognition from other accounts.
What is the biggest risk of hiring a freelancer for Amazon?
A single point of failure. Illness, a larger client or a change of direction leaves the account unattended, and the usual early sign is replies slowing down before the work does. Keep Seller Central, Amazon Ads and Brand Registry in your own company's name, insist on a written record of changes, and name someone responsible for account health notifications.
Should I keep my Amazon account access if an agency runs it?
Always. Whoever does the work, the Seller Central account, the Amazon Ads account and the Brand Registry enrolment should be in your company's name, with the agency or freelancer added as a user. Access can be granted and revoked in minutes; rebuilding advertising history or re-enrolling a brand cannot.
