Omnichannel in 2027: why a one-channel brand is now a risk, and how to add the next channel at a profit

“Omnichannel” has been on conference slides for over a decade, usually next to a picture of a happy shopper and a software logo. Most UK brands we meet have quite rightly ignored it. They sell mainly in one place, usually Amazon, and that place has worked.

For 2027 we think that changes, for reasons that have nothing to do with buzzwords. Shoppers have spread out. The AI assistants people are starting to shop with rarely cite Amazon listings. And when nearly all your sales come through one platform, that platform’s next decision is your biggest business risk. This guide sets out the evidence, what is actually live in the UK, and how to add a second channel without it costing you money.

One point first, because it matters most: omnichannel does not mean being everywhere. It means running the channels you are on as one business, and adding the next one only when it fits.

Multichannel and omnichannel are not the same thing

Multichannel means you sell in more than one place. Plenty of brands do that badly: an Amazon account, a Shopify store and a TikTok Shop, each run by someone different, with three sets of numbers and prices that undercut each other.

Omnichannel means the channels are run as one business:

• One catalogue, so every channel shows the same titles, facts and photos.
• One stock plan, so a TikTok spike never empties your Amazon stock.
• One price position, so no channel undercuts another. Amazon can withhold the Featured Offer from an offer priced above the same product elsewhere, as our Featured Offer guide explains.
• One profit and loss, with profit per order by channel, so budget follows profit.

That is how we run accounts, and our commerce flywheel page shows how the channels feed each other: TikTok creates demand, Amazon converts it, your own store keeps the customer.

Reason 1: your shoppers have already split up

The numbers that matter for a UK brand come from official sources and the platforms themselves:

• 28.8% of retail sales in Great Britain were made online in September 2026, according to the Office for National Statistics¹. Online is no longer a side channel.
• 31% of British online shoppers have bought on TikTok Shop, says TikTok, quoting NielsenIQ data². That is “almost a third”, from a platform that has only operated in the UK for five years.
• More than 300,000 small businesses now sell on TikTok Shop, and LIVE shopping has grown 55% year on year, says TikTok, citing research by Public First³.
• Amazon itself says “more than 95% of independent sellers in Amazon’s store sell across multiple channels”, and is building tools to help them do it⁴. That figure covers its sellers generally, not the UK alone, and the tools are for US sellers only, so far.

None of this means Amazon matters less. It means a growing share of your future customers first meet products somewhere else.

Reason 2: AI assistants rarely cite your Amazon listing

In June 2026 we asked ChatGPT, Claude and Perplexity 3,564 shopping questions about 99 products in 10 categories, and counted every source they cited. The full results are in our State of AI Product Visibility report.

Amazon.com came 62nd of 1,179 sites cited, with 0.3% of citations. Perplexity cited YouTube 1,472 times and never cited Amazon.com.

The lesson is uncomfortable for an Amazon-only brand. When a shopper asks ChatGPT, Claude or Perplexity “what’s the best air fryer?”, the answer is built mostly from reviewers, YouTube videos, forums and brands’ own websites, not from marketplace listings. The exception is Amazon’s own assistant, Rufus, which works inside Amazon and wasn’t part of our study. To be in those answers you need the things omnichannel gives you anyway: your own site with clear product facts, creator and video content, and products good enough for reviewers to recommend.

Three cautions about our own data. The study records the assistants’ answers as they stood in June 2026, and assistants change fast. Most of the sites cited were American, and the study wasn’t set to the UK. And we left eBay, Etsy and AliExpress out of every count. Read it as a strong signal about how assistants answer, not a permanent law.

Reason 3: AI checkout is coming, and it arrives in the US first

Shopping inside AI assistants is real, but most of it isn’t live in the UK yet. This is what each company says on its own pages, as of 25 October 2026:

So nobody can tell you exactly when these reach UK shoppers, and the checkout itself may well happen on your own site rather than inside the assistant. What we can tell you is what they will run on. Shopify says AI-driven traffic to its stores grew eight times year on year in the first quarter of 2026, and orders from AI-powered searches nearly 13 times⁵. Every one of these systems reads product data from somewhere: your Shopify catalogue, your Google Merchant Center feed, your Amazon listing.

Our view for 2027, and it is a view, not a vendor’s promise: at least some of these features will reach UK shoppers during the year. The brands that benefit will be the ones whose product facts are clean and identical on every channel before that happens. That is an omnichannel job.

Reason 4: one channel is one point of failure

The fourth reason is the oldest, and the one owners feel most. If 90% of your sales come through one platform, its rules, fees and algorithms set your profit, and one problem on your account can stop most of your income.

We see this on our calls. A brand we spoke to this year lost its best-seller for months over an authenticity complaint, starting just before Black Friday. When it came back, the ads had to relearn from scratch, and ran expensively while they did. Our account suspension guide covers what to do if it happens to you.

Fees move too, in both directions, and always by someone else’s decision. In 2026 Amazon cut some UK fees: the referral fee on Home Products up to £20 fell “from 15% to 8%“¹¹, which on a £20 item is £3.00 down to £1.60, a saving of £1.40 a sale. From 2 November 2026 its fuel and logistics surcharge on fulfilment fees rises “from 1.5% to 2%”, and festive peak fulfilment fees apply to selected FBA orders in the UK from 15 October 2026 to 14 January 2027¹². Good or bad, a one-channel brand takes each change in full.

What omnichannel is not

Every channel added in a hurry costs money. We have seen each of these:

• The wrong product for the channel. We once pitched TikTok Shop to a brand whose products were, honestly, a long shot for short video. They didn’t go ahead with TikTok, and Amazon turned out to be the right channel for them.
• A channel nobody runs. One brand’s unmanaged TikTok Shop was flooded with free-sample requests from creators with few followers. It cost product and produced little.
• A cheaper price on your own site. If your website undercuts your Amazon price, Amazon can stop featuring your offer, so it drops off the main “Add to basket” button on your best channel. Check Pricing Health before you run a website sale.
• Three teams and three dashboards. Each channel looks good on its own report while the business as a whole stands still.

Which channel to add next

Add one channel at a time, chosen for where you are strong today.

Our guide to TikTok Shop versus Amazon works through that choice in detail.

Whichever you choose, give the new channel two jobs to pass: it must make a profit on its own numbers, and it must not damage the others. Measure the second one against a baseline. Compare branded searches and total sales on your main channel before and after, rather than trusting each channel’s own report. Our three-channel guide shows how to measure that, and how to keep pricing and stock in step, including sharing one pool of stock through Amazon’s Multi-Channel Fulfilment.

The profit test for the new channel

Work out profit per order on the new channel before you launch, from your own costs:

Our two worked examples, on different products, show how differently the costs fall. A £20 Amazon sale left £5.14 after VAT, fees, stock and advertising, at October 2026 rates outside peak; there, fulfilment and stock were the big costs (Amazon fees guide). A £24.99 TikTok Shop order left £5.30; there, creators and ads together cost more than TikTok’s own commission (TikTok Shop fees guide). On your own website there is no marketplace fee, but you pay card fees and postage, and you pay to bring every visitor, through ads, email or creators. Run the sum with your own figures. If the new channel’s profit per order is thin and it doesn’t lift the old one, it isn’t worth the stock and the hours.

A 90-day plan for 2027

Treat week 12 as a first read, not a verdict. New TikTok Shop sellers are paid 31 days after delivery, as our TikTok Shop fees guide explains, and a fair baseline for your main channel needs a comparable period. If someone else has to approve the spend, our one-page business case turns this plan into the numbers a finance director will sign.

Whether a second channel would pay for your products, and which one, is one of the questions a Profit Audit answers. How we measure shows how we work out every £.
