By Gary Carlile, EVP at nShift AI is rapidly becoming the new front door to commerce. In the UK, the shift is already visible. Search is becoming more conversational; AI-generated overviews are reshaping how consumers evaluate options, and tools like ChatGPT are becoming part of the path to purchase. According to Ofcom, Google Search is used by 82% of UK adults, around 30% of searches now show AI overviews, and ChatGPT recorded 1.8 billion UK visits in the first eight months of 2025, up sharply from 368 million in the same period a year earlier. This matters because ecommerce is highly important for the UK economy. According to the Office for National Statistics, online sales accounted for 28.3% of total retail spend in December 2025, with online sales values up 11.1% year over year. So, the question for retailers now isnt whether AI will influence shopping. It already is. The harder question is whether the delivery operation supporting the customer experience is strong enough to support the expectations AI is helping create. As Jurgen Leijdekker, CEO of nShift, explains, AI will reshape ecommerce, but it will not remove the operational realities underneath it. If anything, it will make them more visible. The retailers that benefit most from AI will be the ones with the strongest delivery foundations, connected data, and platforms that can turn intelligence into execution fast.

AI is changing commerce from the start of search and down

The shift is much more than improved search. McKinseys 2025 work on agentic commerce argues that AI agents are beginning to move from answering questions to shaping and executing transactions, estimating that agentic commerce could mediate as much as $1 trillion in US B2C retail revenue by 2030, with global potential reaching $3 trillion to $5 trillion. For retailers, this is both exciting and uncomfortable. Exciting because AI can compress discovery timelines, reduce browsing friction, and help consumers make decisions faster. Uncomfortable because smarter discovery does not remove the operational burden that follows the click. It raises the stakes. Why? Commerce is not won when a customer finds a product. It is won when the retailer keeps the promise. And that promise depends on delivery options, carrier performance, tracking visibility, exception handling, and returns.

AI can improve the promise, but it cannot fulfil it

This is where the next wave of AI adoption is likely to separate the strong operators from weaker ones. AI can make the top of the funnel search feel cleaner and more intelligent. It can improve recommendations, merchandising, service interactions, and even parts of checkout. But it cannot make a fragmented delivery operation reliable. It cannot connect disconnected carrier data by itself. It cannot make poor returns processes feel seamless. If the weaknesses already exist, AI wont eliminate them. It will make them more obvious. This is a particularly important point for UK ecommerce leaders. As the buying journey gets shorter and smarter, customer tolerance for friction does not expand with it. It contracts. So while AI may improve how shoppers arrive at a purchase decision, it will not change the basic physics of delivery. If the promise at checkout is disconnected from reality in execution, the gap becomes visible faster. If post-purchase communication is poor, if the experience breaks in places that customers will remember, if returns are clumsy, the intelligence at the front end starts to look cosmetic.
