7 Ways AI in Retail Buying Transforms Demand Forecasting

Balancing the right product, place, time and price has always been at the heart of retail—but it’s rarely straightforward. Now, AI in retail is making that challenge easier to navigate. From smarter planning to faster decision-making, AI in the retail industry is helping teams work more efficiently while keeping creativity and instinct front and centre. 

With tools now emerging in everything from forecasting to personalisation, AI in retail stores is already making an impact. And as generative AI in retail opens up new ways to create, plan and adapt, it’s an exciting time to explore how this technology can support more agile, collaborative and inspired ways of working. 

 

The Evolution of Retail Buying 

Retail buying has always been part science, part art. It’s a role that blends analytics with creativity, requiring buyers to spot opportunities, predict demand, and curate ranges that resonate. However, with shifting consumer behaviours and an overwhelming amount of data to sift through, making confident decisions has become increasingly complex. This is where AI is beginning to offer real clarity and support. 

Customers are more unpredictable. Trends can go viral in a matter of hours. Supply chains are more complex, and consumer expectations are sky-high. In this dynamic environment, reactive buying is no longer sufficient—retailers need to be proactive, predictive, and agile. 

That’s where AI steps in. Not to replace the buyer’s brain, but to supercharge it. 

 

AI in Retail Buying: The Smart Assistant  

At its core, AI in retail buying is about using machine learning algorithms and data analytics to turn massive volumes of information into actionable insights. Think of AI as a super-assistant with the power to sift through millions of data points at lightning speed and present you with the clearest path forward. 

AI can help retail buyers answer crucial questions like: 

• What will our customers want next season? 

• How much stock should we order, and when? 

• Which products are likely to become slow movers or bestsellers? 

• How should we price our items to optimise margin and demand? 

Here are some key ways AI is shaping smarter merchandising. 

 

1. Demand Forecasting Gets a Crystal Ball 

Accurate demand forecasting is the holy grail of merchandising. Too little stock and you miss sales. Too much and you risk markdowns and wasted inventory. 

AI uses predictive analytics to forecast demand more accurately than ever. It analyses historical sales data, seasonal trends, regional variations, weather patterns, online behaviour and even social media buzz. Crucially, it can adapt forecasts in real time as new data comes in. 

For instance, if there’s an unexpected heatwave in April, AI can detect a spike in searches and purchases for summer dresses and recommend adjusting stock levels accordingly. Or if a celebrity is spotted in a certain brand of trainers, AI can anticipate a surge in demand before it’s obvious to everyone else. 

This is no longer just guesswork—it’s science, with a hint of magic. 

 

2. Smarter Assortment Planning 

Retailers can’t stock everything. Choosing the right assortment (products, colours, sizes and price points) is critical. AI supports smarter assortment planning by helping buyers understand which combinations are most likely to succeed in each store or region. 

By analysing customer preferences, transaction histories and demographic data, AI can suggest assortments that are tailored to each store’s local audience. That way, your shop in Brighton might stock slightly different styles and sizes than the one in Birmingham, even if they’re part of the same chain. 

This level of precision leads to higher sell-through rates, fewer returns, and happier customers. And for buyers, it means less trial and error and more strategic control. 

 

3. Price Optimisation in a Dynamic World 

Pricing is more competitive than ever, and customers can compare options in seconds, so getting your pricing strategy right is crucial. 

AI can simulate different pricing scenarios and predict their impact on sales, margin, and inventory. It considers seasonality, competitor pricing, promotional calendars, and customer behaviour to recommend optimal prices for every SKU, at every stage of its lifecycle. 

This includes markdown optimisation too. Rather than slashing prices uniformly at the end of a season, AI can identify which items should be discounted more aggressively, and which can hold their price. The result? More margin retained and less reliance on blanket sales. 

 

 

 

 

4. Personalised Buying for the Customer of One 

Shoppers increasingly expect tailored experiences, so why should buying decisions be any different? 

AI enables a deeper understanding of customer segments and individual preferences. By mapping customer journeys and preferences, AI can help buyers select products that better match their core audiences. 

This is especially powerful in e-commerce, where AI can help recommend bundles, upsell products, or personalise promotions for different customer types. For example, if data shows that a segment of shoppers tends to buy neutral-toned basics and activewear, the buying team can lean into those categories with confidence. 

 

5. Agile Inventory and Replenishment 

Gone are the days of static inventory systems. Today’s retail environment demands agility. 

AI-powered inventory management tools can track product movement in real time and trigger automatic reorders or redistributions. If a product is flying off the shelves in one region but sitting still in another, AI can recommend moving stock to meet demand and avoid lost sales or overstocking. 

And when integrated with supply chain systems, AI can anticipate potential delays and suggest workarounds, giving buyers a crucial head start on problems before they escalate. 

 

6. Trendspotting and Product Development 

Buyers are constantly on the lookout for the next big thing. But manually tracking emerging trends across Instagram, TikTok, Pinterest, and runway shows? It’s exhausting. 

AI can scan vast digital landscapes to spot trending styles, colours, patterns, and influencers—far faster than any human could. Tools powered by natural language processing (NLP) and computer vision can detect when certain keywords, images, or products start gaining traction. 

For instance, if 'cottagecore cardigans' suddenly spike in conversation, AI tools can flag it early—giving buyers a chance to react ahead of the curve. For private label brands or in-house product development teams, this insight is gold dust. 

 

7. Reducing Waste and Boosting Sustainability 

By improving demand forecasting and reducing overstock, AI helps retailers lower the volume of unsold goods, thereby reducing waste. Additionally, it can support sustainable sourcing by evaluating supplier performance, lead times, and environmental credentials. 

Some platforms even help trace product origins and carbon footprints, offering transparency that buyers can use to make more ethical decisions. In a world where consumers increasingly value sustainability, AI becomes a partner in both profit and purpose. 

 

The Human + AI Partnership 

Let’s be clear: AI isn’t here to take over the art of retail buying. It doesn’t dream up fresh trends, build supplier relationships, or visit showrooms. What it does is free up the buyer’s time and mental bandwidth so they can focus on what they do best—strategy, creativity, and collaboration. 

Think of AI as your digital co-pilot. It’s like having a trusted colleague who’s brilliant with data, never sleeps, and always has your back. And when used thoughtfully, it can transform the buying process into something not only more effective, but more enjoyable. 

 

So, What’s Next? 

As AI continues to evolve, we’re likely to see even more sophisticated tools entering the retail buying space. Think generative AI that can help design products based on trend data. Think deeper integration between buying, supply chain, and marketing—all linked by real-time AI intelligence. 

We’re also likely to see more democratisation of AI. No longer just for the biggest players, cloud-based AI tools are becoming accessible to smaller retailers, giving them the same advantages once reserved for the giants. 

And with the rise of no-code platforms, even buyers with limited technical knowledge can start exploring AI tools and building solutions tailored to their needs. 

 

 

The beauty of AI in retail buying is that it’s not about replacing humans—it’s about augmenting human potential. It’s about collaboration, not competition. 

For buyers, this is an invitation to explore, experiment, and embrace new tools. It’s a chance to combine the best of art and science, instinct and insight, passion and precision. 

Now’s the time to get curious. AI may spark debate, but one thing’s clear—it’s already reshaping retail in powerful ways. With the right approach, the future of smarter merchandising looks not just bright, but brilliant.
