What is Cross-Selling? A Complete Guide

Cross-selling is an approach used to encourage a customer who's already buying from you to add something complementary to their order.

Let’s consider an example you might be familiar with: You’re at your favourite burger joint, eagerly anticipating a slightly indulgent hamburger. The cashier offers you a tempting choice: “Would you like fries and a drink with that?”

Seems like a no-brainer, right? Of course you’d like some crispy, salty fries and an ice-cold drink. Just like that, you’ve been introduced to cross-selling. The beauty of it is that your meal has become more satisfying, and your favourite burger joint has also increased its sales.

Here's how I recommend leveraging this proven sales approach to make existing customers even happier and get you to quota faster.

Cross-selling is a sales strategy where you offer complementary products or services to an existing customer, delivering more value for them while also increasing revenue for your business. It’s a win-win situation for everyone involved, but to get that win, first you have to identify additional customer needs and propose products or services that meet those needs.

Cross-selling refers to selling complementary products after an initial sale. Upselling refers to selling a more expensive version of a product than a prospect originally envisioned, leaning into additional value and ROI as the main selling points.

In the fast-food example, adding chips and a drink to a burger order is the cross-sell. Upselling, however, would be asking the customer if they want to pay more for a double-patty burger instead of a single-patty burger.

As the burger example above shows, cross-selling enables sales teams to bring in sales quickly, while increasing customer satisfaction. That leads to loyalty and long-term, trust-based relationships. When you have these in place, future sales become easier. Here's a closer look at the benefits:

While sellers spend considerable time prospecting for new business, most will agree that it’s a real slog. Plus, the effort often doesn’t pay off. One study reveals that cold calling alone only yields a conversion rate of about 2.7%.

Cross-selling, by contrast, can result in far greater gains. McKinsey , for example, found that cross-selling and category-penetration techniques helped one online retailer increase its yearly sales by 20% and its profits by 30%.

Depending on the contract, product, or business model, customers may cancel without notice, causing revenue fluctuations. In some cases, companies may respond to revenue loss by implementing aggressive sales tactics, which could include heavy discounting or increased prospect outreach.

However, these tactics, if not carefully managed, can potentially harm the brand's reputation. On the other hand, regular cross-selling provides an alternative revenue source, allowing companies to maintain financial stability without resorting to price reductions, all whilst pursuing new customer acquisition strategies.

Traditionally, sales reps viewed a closed deal as the end of the road, but that’s no longer the case. Maintaining a strong relationship with customers is how you build loyalty and recurring sales, and cross-selling can play a central role in that.

It’s important to understand that cross-selling isn’t just about the bottom line; it’s also about empowering customers with a wider array of solutions. By providing them with complementary products or services that align with their needs, you can continue to build trust and show you’re interested in helping them succeed.

Cross-selling isn't just about pitching other products in your portfolio. To make sure you're delivering value to your customer, uncover their motivations and needs in the moment, then match these to products that amplify the impact of past purchases for each customer.

As with any sale, surfacing cross-sell opportunities depends on regular customer interaction and attentive listening. After a sale is complete, be sure to reach out to your customers periodically to ask how the new product is working. This opens the door to new conversations and, ideally, opportunities to cross-sell complementary products.

To cross-sell effectively, treat your customers as people, not cash cows. Demonstrate genuine interest in their success by offering insights, service, and support that earn you the right to suggest relevant cross-selling solutions when the time is right.

This might involve proposing revenue-generating ideas, sharing competitor insights, identifying growth opportunities, or suggesting fresh marketing strategies. Also, if a past customer reaches out with a question or issue, respond quickly. This builds rapport and shows you’re interested in them beyond just making a sale.

Sales pitches often centre around stating a new product's features and price. I've heard this too many times: “We have a new product with X amazing features for just $49. Are you interested?" However, the key should be demonstrating how the product will deliver tangible value and make the customer's life easier. To do this effectively, provide concrete examples of how the solution you're offering will significantly increase ROI and help them hit their goals.

Buying signals are communication cues that signal a customer’s interest in your product or service. Sometimes they surface in casual conversations, but they can also show up in buyer behaviours like “add to cart” actions, online reviews, email engagement, pricing or demo inquiries, and requests for information or support. Pay close attention to these signals to uncover needs and motivations ripe for cross-selling.

Here are a few tactics to get you started:

• Start with an open-ended question: Take a deep dive into the customer’s experience with your product by asking them how it’s working. Avoid yes or no questions so you can gather as much information as possible. For example, if you just sold a piece of software, you might ask: “How did the onboarding of the product go? What were the biggest challenges you faced getting it up and running?”
• Explore ways to make your prospect's life easier: Follow up with specific questions to get to the heart of any ongoing issues, problems, or needs. For example, they may note that onboarding went smoothly except for integration with other tools. You could ask about how much time they have spent on attempting manual integrations and what the impacts have been. This will help you make a case for a cross-sell.
• Identify and present the cross-sell opportunity: With knowledge of the problem in hand, identify a cross-sell solution from your product portfolio and present it to the customer. Keep in mind the value you're trying to offer. In the example above, you'd want a solution that automates integrations and saves the customer time. Emphasise that value when you suggest your solution.

Cross-selling isn't limited to burgers and software. It can be valuable in any industry, with any product.

Case in point: As a sales consultant, my clients sometimes need more than a basic training course or hour-long coaching session. Cross-selling books, additional training, or sales resources is almost always an option — and to make sure the door is open for those cross-sells, I continuously deliver valuable articles or insights to build trust. Then, when an opportunity presents itself, I go for the cross-sell.

This happened recently, shortly after the launch of my third book on sales. I had a few clients at the time who showed some interest in additional training for their sales teams, but I didn't know exactly what they were looking for. So, I asked open-ended questions like, “What industry-specific insights or examples would be helpful?" and “What's the best learning modality for your team?”

Eventually, I uncovered a good fit: a few clients with smaller sales teams that wanted resources sellers could use on their own time. I confidently proposed a cross-sell in our regular check-in conversations, offering bulk copies of my book at a discounted rate. Happily, they accepted, and many have noted since that the book has made their training more impactful.
