What Is AI in Checkout and How Does It Enable Smarter Cross-Sells and Upsells?

In the modern retail landscape, artificial intelligence (AI) is transforming the checkout process. One of the most impactful changes is how AI enables smarter cross-sells and upsells at the moment of purchase. From e-commerce shopping carts to in-store point of sale systems, AI algorithms can analyse customer data in real time to suggest relevant add-on products or premium upgrades. The result is a more personalised shopping experience that boosts sales and average order value (AOV), all while helping customers discover items that meet their needs or interests. This deep dive will explain what AI in checkout means and how it’s revolutionising cross-selling and upselling strategies for retailers across sectors.

‍

Cross-Selling vs Upselling: The Basics

Before exploring AI’s role, it’s important to understand the difference between cross-selling and upselling. These two sales techniques are closely related but serve distinct purposes:

• Cross-selling is recommending complementary products or services that add value to the original purchase. For example, if a customer is buying a smartphone, suggesting a matching phone case or wireless earbuds would be cross-selling. The idea is to fulfill additional needs or enhance the use of the main item. In fashion retail, a cross-sell might be showing a belt or scarf to go with a dress. In grocery, it could be offering a dipping sauce when someone buys chips. Cross-sells increase the total basket size by encouraging extra, related purchases.
• Upselling is encouraging the purchase of a higher-end or upgraded version of the product originally considered. This means persuading the customer to spend a bit more for a premium model or added features. For instance, if someone plans to buy a basic coffee maker, an upsell would present a deluxe model with more functions. In electronics, an upsell might be offering the next model up of a laptop with extra storage and performance. Upselling aims to increase the value of the single item sale by moving the customer to a more expensive option.

Both strategies have long been used in retail because they benefit both the business and the customer when done correctly. Effective cross-selling can help customers by reminding them of useful add-ons (reducing the chance they get home and realise they forgot an accessory), while upselling can ensure customers are aware of all their options and possibly get a product that better fits their needs. Traditionally, these techniques might be executed by a savvy sales associate or simple prompts (“Would you like fries with that?” is a classic fast-food cross-sell). However, human-led efforts have limitations – they rely on the salesperson’s memory and timing, and in online shopping there was historically a lack of personal touch.

This is where AI comes in. AI at checkout can analyse vast amounts of customer and product data instantly and make intelligent suggestions that feel tailor-made. To appreciate how game-changing this is, consider that industry research shows cross-selling and upselling contribute significantly to revenue – in fact, cross-sells can account for roughly 10–30% of total e-commerce revenues, and upselling strategies can lift revenue per customer by an average of 10–30%. Clearly, mastering these techniques is crucial. Now, AI technologies are supercharging cross-sells and upsells, taking them from generic add-on prompts to highly targeted, smart recommendations.

‍

The Role of AI in Modern Checkout

AI in checkout refers to the use of artificial intelligence algorithms at the point of purchase – whether online or in-store – to optimise what products or upgrades are offered to each customer. Instead of static suggestions, AI uses machine learning and predictive analytics to decide in real time what a particular shopper is most likely to want. This represents a shift from one-size-fits-all marketing to dynamic personalisation during the checkout process.

How does it work? AI systems ingest data from many sources: the customer’s browsing history, past purchases, items currently in their cart, demographic information, and even contextual factors like time of day or location. The AI then compares this against patterns learned from other shoppers. For example, an AI might recognise that customers who buy item X often also buy item Y within the same month – so it can suggest item Y at checkout to a new customer purchasing X. These are essentially real-time recommendation engines operating at the moment of checkout decision.

On e-commerce sites, this often appears as sections like “You might also like…” or “Frequently bought together” on the cart or checkout page. Behind the scenes, recommendation algorithms (often using techniques like collaborative filtering or deep learning) are ranking potential products by how relevant they are to the customer. The AI can weigh a variety of factors instantly – such as complementary product pairings, price points, and the customer’s individual preferences – to choose the most enticing suggestion. Importantly, these systems continue to learn and refine suggestions as more data comes in, meaning the recommendations get smarter over time.

In physical retail settings, AI at checkout can take the form of smart Point-of-Sale (POS) systems. Modern POS software may have built-in AI that alerts a cashier or sales associate with a prompt like, “Customer buying a camera – suggest the extended warranty or a camera bag.” Some stores use digital kiosks or customer-facing screens at checkout that display personalised offers (for instance, a screen by the register showing, “Add a memory card for 20% off – recommended for your camera!”). These AI-driven suggestions ensure opportunities aren’t missed just because a busy employee forgot to mention an add-on. They also help standardise upselling practices across all staff and locations by providing consistent, data-backed prompts.

A key advantage of AI is scale and speed. It can analyse millions of data points in seconds, something no human could do in a checkout line or during a short online session. This means even in a large product catalog, AI can find non-obvious connections – perhaps identifying that people who buy a certain running shoe often purchase a specific protein snack, and surfacing that cross-sell suggestion in real time. Additionally, AI doesn’t suffer from “decision fatigue.” It can juggle multiple variables (inventory levels, profit margin, user likelihood to convert on an offer) and always present an optimised suggestion without slowing down the checkout.

‍

AI-Powered Cross-Selling Strategies

AI has truly elevated cross-selling from a simple “customers who bought X also bought Y” into a sophisticated, multi-faceted strategy. Here are some of the key AI-driven cross-selling techniques being used at checkout:

• Personalised Product Recommendations: AI excels at crunching customer data to offer hyper-relevant suggestions. Instead of random or generic combos, AI recommends products that fit that specific customer’s needs and preferences. For example, an online fashion retailer’s AI might recommend a handbag that complements the dress in your cart, based on your past browsing of bohemian-style accessories. If you’re buying a laptop, the AI might suggest a compatible docking station that many others with the same laptop purchased. These recommendations feel helpful rather than pushy because they genuinely align with the shopper’s interests. Many retailers report that this level of personalisation drives significantly higher conversion rates on cross-sells – customers are more likely to add the suggested item when it truly resonates.
• Smart Bundling and “Frequently Bought Together”: Bundling is a classic cross-sell approach where related items are offered as a package, often with a small discount. AI has made bundling much smarter. By analysing purchasing patterns, AI can dynamically create bundles that make sense. For example, Amazon’s AI famously generates a huge portion of sales by bundling products; you might see a camera offered with a tripod and memory card as a bundle because data showed those items often go together. AI ensures these groupings are timely and relevant. A travel booking site’s AI might bundle a hotel, flight, and rental car suggestion in one seamless offer. This not only increases the order value but also improves convenience for the customer (one-stop shopping). Retail giants like Amazon, Walmart, and Target all use AI-driven “frequently bought together” suggestions both online and in-store, knowing that an intelligently presented bundle can encourage customers to buy the whole set of items.
• Real-Time Complementary Suggestions: AI’s ability to work in real time means cross-sell offers can be adjusted on the fly during the checkout flow. If a shopper adds a product to their cart, the site can instantly update and display a complementary item. For instance, adding a printer to the cart could trigger an immediate suggestion for printer ink or paper. If the customer removes an item or adds a different category of product, the AI can change the recommendation accordingly. This agility keeps the suggestions contextually relevant at each moment, increasing the chance of a successful cross-sell. It’s like having a sales assistant who listens and responds instantly to what the customer picks up.
• Chatbots and Virtual Shopping Assistants: Some retailers deploy AI chatbots that engage customers in conversation during the shopping or checkout process. These AI assistants can answer questions (e.g. about product details or shipping) and simultaneously recommend add-ons based on the dialogue. For example, if a customer is chatting about a new phone purchase, the chatbot might proactively suggest, “Do you have a case for your phone? We have one that matches your style.” Studies have shown that businesses using AI-driven chat engagement can see a notable uptick in cross-sell revenue (often cited in the range of 15–25% increases), because the chatbot never misses a chance to make a relevant suggestion. Unlike a static page, an interactive bot can also address any objections (“Is that case durable?”) and thus smooth the path to adding that extra item.
• Email and Retargeting AI for Post-Checkout Cross-Sells: While our focus is on checkout, it’s worth noting that AI also extends cross-selling opportunities beyond the immediate transaction. AI algorithms can trigger follow-up emails or ads featuring complementary products if a purchase is completed (or even if a cart is abandoned). For instance, if you buy a vacuum cleaner, an AI-powered system might email you a week later suggesting HEPA filter replacements or carpet cleaning solution. These communications are personalised based on what you bought and when you bought it. They keep the conversation going and can bring customers back for related items, effectively cross-selling after checkout. AI ensures these recommendations are timely and relevant rather than random spam, which in turn keeps customers engaged rather than annoyed.

Overall, AI-powered cross-selling feels like a helpful concierge service when done correctly. The customer benefits by discovering useful add-ons or accessories they might have otherwise missed, often at an opportune moment (when they’re already in buying mode). The retailer benefits through higher revenue per transaction and improved customer satisfaction. Cross-sell suggestions powered by AI have to be finely tuned – the goal is to be relevant and welcome, not to overwhelm the shopper with too many or unrelated suggestions. When balanced right, it’s a win-win strategy.

Example: An AI-driven cross-sell on an e-commerce site – Amazon’s checkout suggests complementary items (“Customers also bought these items”) for a tablet in the cart, such as cases and accessories. These recommendations are based on buying patterns of similar customers, increasing the chance the shopper adds one to their order.

‍

AI-Powered Upselling Strategies

Just as AI enhances cross-selling, it also brings upselling strategies to the next level by identifying when and how to encourage customers toward a premium choice. Some key AI-driven upselling approaches include:

• Product Comparisons and Recommendations for Upgrades: One reason customers hesitate to choose a higher-priced option is lack of clarity on the benefits. AI can tackle this by providing smart product comparisons at checkout. For example, if you’re about to buy a standard model of a smartphone, an AI system might pop up a comparison showing the premium model’s advantages – perhaps a better camera, longer battery life, and only $100 more. These AI-generated comparisons can highlight features most relevant to the customer (based on what it knows about their usage or preferences). This helps customers make informed decisions and often demonstrates the value of upgrading. Retailers like electronics stores use AI on their websites to say, “For $20 more, upgrade to the Pro version which has X feature.” By tailoring the upsell pitch to what a customer cares about (e.g. emphasising camera quality to a photography enthusiast), AI upsells feel more convincing and less like a generic push.
• Dynamic Pricing and Special Offers for Upsells: AI can determine the optimal incentives and timing to present an upsell. Using predictive analytics, AI figures out if a customer is on the fence and what might sway them. For instance, an AI might detect that a shopper has looked at a higher-tier product multiple times but added a lower-tier one to the cart. At checkout, the system could offer a limited-time discount or bonus (like free shipping or a free accessory) if the customer upgrades to the higher-tier product. These time-sensitive upsell offers leverage AI’s ability to personalise deals: one customer might get a 10% upgrade discount, while another might be more motivated by an extended warranty thrown in – depending on what the AI predicts will work. Research by retail analysts has found that such AI-driven discounting strategies can boost upsell conversion significantly (one study by Forrester noted up to a 30% increase in conversion when AI was used to optimise the offer). The key is that AI does not blanket everyone with the same offer; it uses customer data and even broader conditions (like inventory levels or seasonal trends) to tailor the upsell proposition for maximum impact.
• Timing the Upsell Pitch with AI: Knowing when to suggest an upsell is as important as the offer itself. AI systems monitor customer behavior to pinpoint the right moment. In an online setting, AI might wait until the customer has reviewed their cart and is about to click “Place Order” – a moment of commitment – to pop up an upsell like, “Upgrade to Premium for just $X more.” In a physical store, an AI-equipped mobile POS can signal an associate when scanning an item, like “Customer buying mid-range TV – upsell to larger screen model available for $200 more.” If the associate sees the prompt at exactly the moment the customer is considering their purchase, it can be very effective. Because AI bases these prompts on data (e.g. similar customers who often chose to upgrade when prompted at this point), the retailer can capture additional sales that might otherwise be lost with poor timing.
• Personalised Upsell Messaging: AI also helps in crafting the language and framing of upsell offers in a personalised way. For instance, an AI might learn that a particular customer is very warranty-conscious (maybe they bought extended protection plans for other electronics), so at checkout it emphasises the peace of mind aspect: “Protect your investment – upgrade to the Pro model which comes with 2 years warranty included.” Another customer might value performance, so the message could highlight speed or power: “Upgrade now for a laptop with 2x the memory – ideal for heavy multitasking and work.” By speaking to the customer’s priorities (informed by their past interactions or profile), AI upsell prompts can be more persuasive than a one-size-fits-all blurb. It feels like the store understands what you value, making the upsell suggestion far more compelling.

In practice, AI-driven upselling aims to ensure the customer truly sees the added value in spending a bit more. It’s not about tricking anyone into something unnecessary – the best upsells satisfy the customer by delivering a better solution to their problem, while also increasing revenue. With AI, retailers have observed higher average transaction values and higher customer satisfaction (because the upsell often does align better with needs). However, as with cross-selling, moderation is key. The upsell should be presented as a helpful option, not a pressure tactic. AI can even gauge customer sentiment (through clicks or responses) and back off if it senses disinterest, ensuring the upsell attempt doesn’t sour the shopping experience.

‍

Benefits for Retailers and Customers

Implementing AI in the checkout process for cross-sells and upsells brings significant benefits to both retailers and customers:

• Increased Revenue and Average Order Value: The most obvious benefit for retailers is a boost in sales. By intelligently suggesting additional products or upgrades, retailers can capture extra revenue that might have been left on the table. Even small increases per transaction add up dramatically at scale. Many businesses report double-digit percentage increases in average order value after rolling out AI recommendation systems. For example, if upselling and cross-selling techniques contribute an extra 15% in sales overall (a figure in line with industry benchmarks), that’s a massive gain without needing to acquire new customers. AI essentially helps retailers maximise the value of each customer interaction. This is especially crucial in competitive markets where margins are thin – getting that add-on sale or premium upgrade can be the difference to hitting profit targets.
• Improved Customer Experience and Satisfaction: When done right, AI-driven suggestions actually make the shopping experience more convenient and satisfying for customers. Shoppers often appreciate relevant recommendations that save them time or remind them of something they need. For instance, a customer buying a baby stroller might genuinely find it helpful that the site suggests a compatible rain cover or car seat adapter – it saves them from searching separately. Upselling to a better product can lead to the customer being happier in the long run (imagine realising later you needed the larger capacity fridge – an AI upsell at purchase time could have guided you to that initially). Personalised offers also make customers feel understood by the brand. Rather than bombarding everyone with the same promotion, the AI is curating options that fit the individual. This personal touch can foster loyalty; in fact, surveys have found that a majority of consumers (well over 60%) are more likely to return to retailers that provide personalised experiences. By helping customers discover more value and relevant products, AI can increase customer satisfaction and repeat business.
• Reduced Decision Fatigue: Shoppers today face an overload of choices. One subtle but important benefit of AI suggestions is that they can simplify decision-making. When a customer is on the fence about what else they might need, a well-placed recommendation can provide clarity. It’s like having a knowledgeable assistant guiding you: “Many people who bought this also liked this accessory; it might be useful for you.” This reduces the mental effort for customers to manually browse or research complementary items. Instead of viewing AI recommendations as ads, customers often see them as tips or advice, especially if they clearly align with their needs. This streamlined experience – fewer clicks to find what you want – makes shopping less tiring and more enjoyable.
• Higher Conversion Rates & Lower Cart Abandonment: Intelligent cross-sells and upsells can also have a positive effect on overall conversion. When customers see useful add-ons or upgrades, it can increase their confidence in the purchase (the logic being, “others bought these, so it must be a good idea” or “this premium option might suit me better, and I feel good about buying the right one”). Additionally, some AI systems tailor the checkout page with messaging that emphasises value, which can reassure customers and push them to complete the order. For example, showing how the bundle saves money compared to buying items separately can be the nudge that finalises the sale. By making the cart seem more valuable and the process more personalised, AI can subtly decrease the chance of a customer abandoning their cart.
• Optimised Inventory and Marketing Strategy: On the retailer’s back-end, the data collected and actions taken by AI at checkout provide valuable insights. Retailers can see which cross-sell pairings are most popular, which upsells are often accepted, or which customer segments respond to what offers. This information can inform inventory decisions (e.g. stock more of the high-attach accessory items) and broader marketing strategies (perhaps bundle certain products in promotions because AI found they naturally go together). In this way, AI at checkout not only drives immediate sales but also helps optimise operations, aligning product bundles, pricing, and promotions with real consumer behavior patterns.

For customers and retailers alike, the bottom line is that AI in checkout makes the sales process smarter and more efficient. Customers get more value with less effort, and retailers increase sales and learn more about consumer preferences. It’s a virtuous cycle that, when managed ethically and thoughtfully, builds a better shopping relationship on both sides.

Mobile POS and Omnichannel Integration

A standout feature of AI in retail is how it supports an omnichannel retail tech strategy – blending in-store and online channels into one seamless experience. An important component here is the rise of mobile POS systems and how AI integrates with them for cross-selling and upselling.

Mobile POS (Point of Sale) refers to equipping store staff with handheld devices or tablets that can ring up sales from anywhere in the store, rather than relying only on a fixed checkout counter. These devices often have access to the retailer’s customer and product databases. When combined with AI, mobile POS becomes a powerful tool for personalised selling on the shop floor. For example, imagine a customer is trying on shoes in a store and decides to purchase. A sales associate with a tablet can check the customer out on the spot. If that tablet has an AI assistant, it might prompt the associate with a cross-sell: “This customer bought running shoes; recommend running socks or a water bottle.” The associate, armed with that insight, can casually suggest, “We have cushioned running socks that go well with those shoes – would you like to take a look?” Because the recommendation is data-driven (perhaps based on common combinations or the customer’s past purchases), it’s likely to be on-target. This empowers store staff to deliver knowledgeable, tailored service without needing to personally remember every complementary item for every product.

Omnichannel integration means the AI can use data from all channels. If a shopper is logged into a loyalty account, a store associate’s mobile POS might show what items the customer browsed online or left in their online cart. This allows for an informed conversation: “I saw you were looking at our sustainable fashion line online – we have a jacket in store that matches the style you liked.” Here we see AI bridging channels to create a unified experience. Whether the customer is online or in a physical location, the recommendations adapt but remain consistent in understanding the customer. In fact, retailers aiming for true omnichannel personalisation rely on AI to synthesise data from e-commerce, mobile apps, and in-store interactions. The AI can, for instance, recognise that a customer frequently buys eco-friendly products and then ensure that in-store, the POS suggests a sustainable fashion item as an upsell (aligning with that customer’s values and likely interests).

Another aspect is how AI aids checkout-free or self-checkout experiences. In some high-tech stores, customers might scan items with their phone or at a kiosk. AI can still play the cross-sell role here by suggesting, on the screen, additional products before the customer confirms payment. Because there’s no human cashier to verbally upsell, the AI’s on-screen recommendation is crucial to capture that extra sale. For example, at a self-checkout for a grocery store, the screen might display: “Don’t forget the dip for your chips! - Add to order with one tap.” This is driven by AI predicting what goes well with what’s being bought. Mobile checkout apps also send push notifications – an AI might trigger a message like “You’re $5 away from free shipping, consider adding one of these popular items” to encourage adding another product, effectively upselling the order size.

Crucially, these AI-powered suggestions across channels need to feel cohesive. Consistency is key in omnichannel retail tech. If an online platform knows a customer’s preferences, the store should too. AI helps by acting as the brain that all channels tap into. The benefit is a customer can start a journey in one channel and finish in another, with intelligent recommendations following along. Perhaps a customer added a high-end coffee maker to their online cart but didn’t check out. When they walk into the store, an associate’s tablet (via AI) might alert them that this customer showed interest in that coffee maker, enabling the associate to upsell to it or a similar model in person. This creates a smooth experience rather than a disjointed one.

In summary, mobile POS and AI together transform how cross-sells and upsells are delivered in brick-and-mortar settings, making them as personalised as online experiences. And by integrating data across online and offline, AI ensures customers receive a unified, convenient journey. Retail executives often view this as the future: a customer-centric approach where no matter how or where the shopper chooses to buy, the AI-driven checkout experience will intelligently enhance the sale.

‍

Challenges and Considerations

While AI-powered cross-selling and upselling offer many advantages, retailers must navigate several challenges and ethical considerations to implement them successfully:

• Data Privacy and Security: AI’s effectiveness comes from using customer data – purchase history, browsing behavior, preferences, etc. However, handling this data responsibly is paramount. Customers are increasingly aware of privacy issues and expect transparency. Retailers must ensure that their AI systems comply with privacy laws (like GDPR or other regional regulations) and that data is stored securely. There’s a fine line between helpful personalisation and feeling like “Big Brother” is watching. For instance, a recommendation that is too eerily specific might make a customer wonder if their privacy has been invaded. Companies should be clear about data policies and possibly allow customers to opt out of personalised suggestions if they choose. Building trust is essential; otherwise, even the smartest AI suggestion will be met with suspicion rather than conversion.
• Avoiding Over-Personalisation (Being Too Pushy): More is not always better when it comes to recommendations. One risk is overloading the customer with suggestions, which can come across as aggressive and actually deter the sale. If every time a customer adds something to the cart they face a barrage of pop-ups for extras, it may frustrate them. AI systems should be tuned to strike a balance – offering the most relevant one or two suggestions, not ten irrelevant ones. Also, the AI should recognise cues if a customer isn’t interested (for example, if they consistently ignore or close recommendations). Blatantly repeating the same upsell after a customer has dismissed it can harm the experience. Essentially, retailers must calibrate the AI to be helpful, not annoying. Sometimes less is more; a subtle prompt can be more effective than an in-your-face upsell, especially with savvy consumers who might rebel against a hard sell.
• Integration with Existing Systems: Introducing AI into checkout requires technical integration with POS systems, e-commerce platforms, inventory databases, etc. Many retailers face the challenge of making new AI tools work with legacy systems. A poorly executed integration could slow down the checkout process (a big no-no, since speed is crucial at purchase time) or cause glitches in what is displayed to customers. Businesses need to invest in robust integration and testing. This might involve retraining staff to work with AI-driven interfaces too. For example, store associates must learn to trust and use tablet prompts effectively in conversation with customers. There can be a learning curve, and it’s important to manage that change so the technology truly augments the process rather than complicating it. Choosing the right AI solution that is compatible with your tech stack, or custom-developing with good support, is an important decision.
• Algorithm Bias and Fairness: AI models can inadvertently develop biases based on the data they’re trained on. In a retail context, this might mean the AI overly promotes certain brands or always upsells higher-priced items in a way that doesn’t actually suit the customer’s budget or needs. It could also systematically recommend items that have higher margins for the company but are of lower relevance, which might short-term boost sales but hurt customer trust long-term. Retailers have to regularly monitor and tune their recommendation algorithms to ensure they are aligning with genuine customer interest and not introducing unfair bias (for instance, not marginalising certain products or categories unintentionally). Transparency is helpful: some advanced AI systems provide explanations (e.g. “We suggested this because…”) which can help teams audit why the AI is making certain suggestions and adjust if necessary.
• Maintaining Human Touch: There’s a consideration about how AI and human salesmanship interplay. In physical stores especially, an over-reliance on AI prompts could make interactions feel robotic if associates just parrot whatever the tablet says. Training is needed so staff can incorporate AI suggestions naturally, adding their personal touch and judgement. The human element remains vital – some customers will always respond better to a friendly, empathetic suggestion than a purely algorithmic one. Retailers should use AI as a tool to assist humans, not to replace the relational aspect of sales.
• Measuring Effectiveness and Adjusting: Finally, a practical consideration is setting up the right KPIs and feedback loops. Retailers need to measure the impact of AI-driven upsells/cross-sells (conversion rates on recommendations, average order value changes, etc.) and listen to customer feedback. If certain suggestions are frequently ignored or if customers provide feedback that something felt off, the strategy should be tweaked. AI is not a set-and-forget solution – it requires continuous improvement. The good news is AI itself can help in optimisation: A/B testing different recommendation approaches can be done at scale, and the AI can learn from the results. The team behind it should be actively managing the AI, almost like a member of the sales team that needs guidance and evaluation.

In tackling these challenges, retailers can ensure that their AI-enhanced checkout remains customer-friendly, trustworthy, and effective. It’s about using AI’s power responsibly. When customers feel that recommendations genuinely help them (and their data isn’t misused), they will embrace the experience. On the other hand, any breach of trust or poor execution can lead to backlash. Therefore, thoughtful implementation is as important as the technology itself.

Key Statistics: AI in Cross-Selling and Upselling

• Cross-Selling Revenue Impact: Cross-selling techniques contribute an estimated 10% to 30% of e-commerce revenues on average. Brands that excel at cross-selling have reported roughly 20% increases in profits driven by those additional item sales. This highlights how much of a retailer’s income can come from smart add-on suggestions rather than new customer acquisitions.
• Upselling Increases Order Value: Effective upselling can boost revenue per customer by around 10% to 30%. By encouraging shoppers to opt for premium options or add upgrades, companies significantly raise their average order value (AOV). For example, research by Accenture and others found upselling to be one of the most effective tactics to improve profit margins without increasing marketing spend.
• Amazon’s AI Recommendation Success: Industry examples show the power of AI – Amazon attributes roughly 35% of its sales to AI-powered product recommendations (including cross-sells and upsells). These personalised suggestions (“Customers who bought this also bought…” and “Frequently Bought Together”) driven by AI have become a cornerstone of Amazon’s revenue strategy.
• Adoption of AI by Retailers: Companies are rapidly embracing AI for sales. By 2025, it’s predicted that about 75% of retailers will be using AI to identify and drive upsell/cross-sell opportunities. In surveys, over 60% of businesses say that AI-driven personalisation is crucial for staying competitive, showing a strong belief that these tools are now essential in modern retail.
• Conversion Uplift from Personalisation: Personalised recommendations not only increase immediate sales but also loyalty. Studies indicate that 61% of consumers are more likely to return to a website that offers personalised product suggestions. Additionally, businesses implementing AI-powered upselling and cross-selling report on average around 15% higher sales revenue compared to those that don’t use AI, due to better conversion rates and customer retention.
• Impact of AI on Upsell Conversion: AI-driven strategies can make upsell offers more tempting. For instance, analytics have shown that using AI to tailor discounts or timing for upsells can improve upsell conversion rates by up to 30%. A well-targeted upsell (e.g. limited-time upgrade offer generated by AI insight) converts significantly better than a generic upsell message.

These stats underscore the transformative effect AI is having on retail sales strategies. Companies leveraging AI at checkout are seeing substantial gains in revenue and customer engagement, validating the investment in these technologies. As adoption grows, these numbers may climb even higher, making AI-driven cross-selling and upselling a standard best practice in retail.
