Boosting Sales: The Ultimate Guide to Upselling and Cross-Selling in eCommerce

Have you ever browsed for a new t-shirt online and found yourself adding a pair of socks or a matching cap to your cart?

Maybe you spotted a premium version of the item you were about to buy and decided to upgrade?

This is the power of upselling and cross-selling. Which are two highly effective strategies that not only boost sales but also enhance the customer shopping experience!

Let’s take a look at the key differences between these techniques and how you can use them to maximise revenue while building customer loyalty.



Upselling vs. Cross-Selling: So, what’s the Difference? 

Upselling is Encouraging Premium Choices:

Upselling is about guiding customers toward a higher-value version of the product they’re considering.

🛍 For Example: Think of a trip to the cinema to watch a movie. The cinema will offer a large popcorn for just £1 more than a medium. Many people will choose the bigger size because it feels like a better deal.

Similarly, an online store might highlight the benefits of a deluxe edition, extra features, or a subscription plan to encourage a more valuable purchase.

Cross-selling is Complementing the Purchase:

Cross-selling, on the other hand, involves suggesting related or complementary products to increase the order’s total value.

🛍 An example is: A customer buying a new phone and being offered a screen protector and a stylish phone case at checkout.

Both upselling and cross-selling work best when customers feel natural rather than pushy, ultimately improving the shopping experience and increasing customer satisfaction, retention, and loyalty.

Why Upselling and Cross-Selling Matter:

These tactics are game-changers for eCommerce businesses of all sizes.

Here’s why:

Higher Average Order Value (AOV):

Customers spend more per transaction when presented with relevant upsell and cross-sell opportunities.
Increased Customer Lifetime Value (LTV):

Satisfied customers return for future purchases, increasing their long-term value.
Better Customer Experience:

Smart recommendations create a personalised shopping journey, strengthening brand loyalty.
More Brand Advocates:

Happy customers are more likely to share positive experiences and recommend your business.

According to industry research, upselling and cross-selling can increase sales by 10% to 30%, making them essential for any eCommerce strategy.

7 Proven Ways to Upsell and Cross-Sell in eCommerce

1. Display a “Related Products” Gallery:

One of the simplest ways to encourage additional purchases is by showcasing related items on product pages.

💡For example, a fashion brand might include a “Complete Your Look” section, featuring accessories that pair well with a selected dress. Similarly, a kitchenware store could suggest complementary utensils when a customer buys a chef’s knife.

By making recommendations at the right moment, you can increase order sizes effortlessly.

2. Offer Bundles and Multipacks:

Product bundling is a classic cross-selling tactic that offers a better deal for customers while increasing overall sales.

💡 Example: A grooming brand may offer a bundle containing shaving cream, razors, and aftershave, providing a discount when purchased together instead of separately.

Multipacks work similarly, encouraging customers to buy in bulk at a lower per-unit price. This tactic works especially well for consumable products like skincare, supplements, or coffee.

3. Use Incentives and Rewards to Drive Larger Purchases:

A strategic incentive can make upselling and cross-selling even more effective. Consider offering:

✔ Free shipping for orders over a certain amount
✔ Loyalty points that reward larger purchases
✔ Exclusive discounts on premium versions of products

💡For instance, a fashion store might offer 10% off purchases over £100, subtly encouraging shoppers to add one more item to their carts.

4. Highlight Premium Versions of Products

A side-by-side comparison of basic vs. premium versions of a product can nudge customers toward the higher-value option.

📌 Example: A laptop retailer can display a performance comparison between standard and pro models, making it easier for buyers to justify upgrading to a more powerful device.

This strategy works across industries, from electronics and furniture to beauty and fitness, where premium choices offer better features, durability, or long-term savings.

5. Introduce Subscription Options

Subscription models turn one-time purchases into recurring revenue streams while adding convenience for customers.

💡Example: A pet supply brand could offer monthly deliveries of dog food, ensuring pet owners never run out.

By automating reorders, subscriptions increase customer retention and provide predictable revenue.

6. Offer Free Samples to Encourage Future Purchases

Including free samples in shipments can entice customers to try new products they wouldn’t have considered otherwise.

🛍 Example: A skincare company could include a travel-sized moisturiser with a customer’s order. If they love it, they’re likely to return for a full-sized version later.

Some brands even allow customers to choose their free samples at checkout, making the experience feel even more personalised.

7. Use Coupons and Discounts to Drive Repeat Sales

Offering a limited-time discount on future purchases can encourage customers to return sooner.

🛍 For example, after a successful purchase, send an email with a 10% off coupon valid for the next 14 days. This creates urgency and capitalises on the “shopper’s high," the excitement customers feel after making a great purchase.

Best Practices for Upselling and Cross-Selling Success

Once you’ve integrated these strategies into your online store, focus on fine-tuning your approach for maximum impact.

Know Your Customers:

Analyse customer behaviour, past purchases, and preferences to offer the most relevant recommendations.

Follow the 25% Rule:

When upselling, keep the price increase within 25% of the original item to avoid overwhelming customers.

Clearly Communicate Value:

Make sure customers see the benefits of upgrading or bundling, whether it's cost savings, better quality, or extra features.

Leverage Live Chat for Personalised Suggestions:

A live chat feature allows real-time interaction, where you can offer tailored recommendations based on customer needs.

Encourage User-Generated Content (UGC):

Showcase customer photos, testimonials, and social media posts to reinforce the value of related products.

Gather and Act on Customer Feedback:

Monitor customer reviews and feedback to refine your upselling and cross-selling strategy over time.

Final Thoughts:

Build Stronger Customer Relationships Through Smart Selling

The best eCommerce strategies go beyond just making a sale; they focus on building long-term customer relationships.

By mastering upselling and cross-selling, you can:
✔ Boost revenue without acquiring new customers
✔ Enhance the shopping experience through personalization
✔ Strengthen brand loyalty and advocacy

When done with integrity and customer-centricity, these techniques will help transform one-time buyers into lifelong supporters of your brand.
