TikTok Shop vs Amazon: which channel should a UK brand start with?

“TikTok Shop or Amazon?” sounds like a choice between two marketplaces. It is really a choice between two kinds of shopper. One arrives on Amazon already looking for something like your product. The other is scrolling TikTok and had no plan to buy anything until a video changed their mind. Mr. Prime runs accounts on both, so this guide compares them on the things that decide profit for a UK brand: demand, fees, content, fulfilment, returns and cash flow. If you have already chosen TikTok, start with our guide to how to sell on TikTok Shop in the UK.

Two kinds of demand

Amazon is a search engine with a checkout. Shoppers type what they need, compare listings, read reviews and buy. Your job is to be the best answer to searches that already happen. That favours products people look for by name or type: replacements, refills, supplements, tools, household essentials, anything bought after comparison.

TikTok Shop is discovery. Nobody opens TikTok to buy a specific product. People are shown a video by a creator, or by you, and the purchase happens in the same scroll. That favours products that show their value in seconds: a visible before and after, a satisfying demonstration, a clever design, a gift.

Neither is better in general. The question is which one matches how your product is bought today, and which kind of work your team can do every week.

The comparison at a glance

Fees: the headline rate is not the cost

Amazon. The referral fee is 15% for “everything else” and most mainstream categories. Since January 2026 several categories charge less on cheaper items, such as 8% on Home Products up to £20 and 5% on Vitamins, Minerals and Supplements up to £10¹⁰. Add FBA fees if Amazon fulfils for you, and a 2% digital services fee on Amazon’s selling and FBA fees for UK sales¹⁰. Our guide to Amazon selling fees in the UK lists every fee, and the FBA calculator for the UK works them out for your product.

TikTok Shop. TikTok’s UK policy sets the commission at 9%, “inclusive of applicable taxes, including but not limited to Value Added Tax"². Products in specified Electronics and Beauty & Personal Care categories get a 4-point reduction, which keeps them at an effective 5%¹. The commission is charged on the order total including customer-paid shipping and any platform-funded discount, less refunds³. The policy page we checked is dated 18 September 2025, and we found no change to the UK rate in 2026 on TikTok’s seller pages as at 30 September 2026. TikTok runs frequent incentives for new sellers and for some ad campaigns, so check Seller Center for what applies to you. Our guide to TikTok Shop fees in the UK goes through each fee in detail.

Creator commission is the big one. Most TikTok Shop sales for a new brand come through affiliate creators. You set the commission rate per product, and creators are paid on revenue minus refunds⁴. TikTok’s own UK playbook suggests 10% to 15% as an average rate⁵. Add free samples, and often a fee for guaranteed content from larger creators, and the cost of selling through creators usually exceeds TikTok’s platform commission.

A worked example: one £20 product on each channel

The fee rules below are Amazon’s and TikTok’s published UK rates¹⁰². Everything else is illustrative, so use your own numbers.

Two things stand out. TikTok’s lower platform fee is outweighed as soon as a creator takes 15%. And the TikTok sale made through your own content is the most profitable line in the table. The brands that do well on TikTok Shop usually build both: creators for reach, and their own content, which gets cheaper per sale the longer they keep making it.

Fulfilment: FBA and FBT

Amazon FBA stores your stock and picks, packs and ships orders, and provides customer service for those products¹¹. Our guide to what Amazon FBA is explains how it works and what it costs.

Fulfilled by TikTok Shop (FBT) is available in the UK. You send stock to a TikTok-run warehouse and pay storage, per-item handling and shipping fees; TikTok charges receiving fees only for loose-loaded containers⁷. If you would rather keep stock yourself, Shipped via Platform, TikTok’s own shipping service, charges from a published rate card; a new card applies to parcels delivered from 1 November 2026⁸.

In practice, many brands keep one stock pool and use Amazon’s Multi-Channel Fulfilment, a 3PL or FBT depending on volume. Whatever you choose, plan buffers for TikTok spikes: a video that takes off can empty a month’s stock in days.

Returns

On paper the two channels are similar. Amazon.co.uk and many of its sellers accept returns of most items within 30 days of delivery¹³, and TikTok Shop UK customers can request a return or refund for up to 30 days from delivery⁹.

In practice, return rates depend on how the product was bought. In the accounts we run, impulse-led lines on TikTok can see more “changed my mind” returns than the same product bought after a search on Amazon, especially in fashion and sizing-sensitive categories. That is our experience, not a published figure, so measure return rates per product on each channel before you commit budget.

Cash flow: when you actually get paid

This is the difference new brands most often underestimate.

• Amazon holds funds until seven days after delivery as standard (“DD+7”), after which they can be paid out on your settlement cycle or on request¹².
• TikTok Shop UK puts newly onboarded sellers, and sellers in a probation period, on a 31-day introductory settlement period, counted from delivery. The standard period after that is 8 days, and sellers who meet TikTok’s performance criteria can move to 3-day or 1-day settlement⁶.

So in your first months on TikTok Shop, you pay for stock, samples, shipping and content, and wait more than a month after delivery for the sales income. If a video takes off in week three, you need the cash to restock before the money from those orders arrives. Plan the working capital before you launch.

Content: the cost that never stops

On Amazon, most of the content cost comes at the start: photography, a clear title and bullet points, A+ Content and a Brand Store. It then needs upkeep, not constant renewal. Our guides to Amazon listing optimisation and A+ Content design cover what good looks like.

TikTok Shop needs new content every week. Videos wear out in days, creators need briefing, samples and follow-up, and live selling needs presenters and planning. If nobody in the business can own that rhythm, either budget for someone who can or start on Amazon.

How the two channels work together

The strongest position is usually both, with each doing the job it is best at: TikTok creating demand, Amazon capturing it.

We have seen this pattern in accounts we manage. A UK brand we work with had a TikTok video take off with no advertising behind it, and over the following days its Amazon sales rose sharply while its Amazon advertising stayed unchanged. Comments under the video asked where to buy, and many viewers went to Amazon, where they already had an account and Prime delivery. That is our observation, not a published statistic, and it does not happen for every video or product.

It is also invisible in TikTok Shop’s own reports, which only count sales made in the app. To measure it:

• Track branded searches on Amazon in the Search Query Performance dashboard in Brand Analytics, which shows search volume, impressions, clicks, basket adds and purchases for queries related to your brand¹⁴. Compare the weeks before and after a TikTok push.
• Judge both channels on combined profit, not each channel’s return on ad spend. Cutting TikTok because its in-app return looks weak can quietly cut Amazon sales too.
• Keep pricing coherent across channels. Different pack sizes or bundles per channel reduce direct price comparisons.

Once both are running, our guide to running Amazon, TikTok Shop and your own site together covers channel roles, pricing, shared stock and profit per channel.

Decision table: where to start

Adding the second channel

Whichever channel you start with, add the second once the first is profitable and running without the founder doing everything. From Amazon, bring your best-reviewed product to TikTok with a creator brief built around what reviewers praise. From TikTok, bring your proven hero product to Amazon, with a listing written for the searches your videos have started, and put a small amount of advertising behind your brand terms.

If you are also weighing up how to sell on Amazon itself, our guide to Vendor Central vs Seller Central applies the same product-by-product thinking.

Channel choice is downstream of unit economics. Pick the channel where the margin is strongest and commit to it properly.
