What Is Cross-Selling?

Cross-selling is all about offering complementary products that enhance the customer’s main purchase.
Think of it as helping customers get the most complete experience from what they’ve already decided to buy.
👉 Example:
When someone orders a burger and the cashier asks, “Many customers enjoy a pastry with their drink. Would you like to try one?” — that’s a cross-sell.
The fries and drink make the meal better — they don’t replace the burger, they add value to it.
In eCommerce, this might look like:
- Suggesting a phone case when someone buys a phone.
- Recommending a laptop stand when someone adds a MacBook to their cart.
- Showing “frequently bought together” bundles on a product page.
Cross-selling increases the number of items per order, and when done right, it improves both your sales and the customer’s satisfaction.
What Is Upselling?

Upselling, on the other hand, is about encouraging customers to buy a better or upgraded version of what they already want.
It’s not about adding something new — it’s about offering more value in the same product line.
👉 Example:
When the cashier asks, ““You can go for a Grande instead of Tall — it’s only a small extra charge” — that’s an upsell. The product doesn’t change — it’s just a bigger, more premium version.
In online stores, upselling looks like:
- Suggesting a 256GB iPhone instead of the 128GB model.
- Recommending a Pro plan instead of a Basic subscription.
- Highlighting a premium fabric or exclusive edition for a small price increase.
2- Key Differences Between Upselling and Cross-Selling
| Upselling | Cross-Selling | |
| Focus | Upselling promotes a pricier or upgraded version of the chosen product | Cross-selling proposes complementary items. |
| Objective | Upselling raises profit by shifting customers to premium options | Cross-selling raises profit by expanding the cart with relevant add-ons. |
| Product Relationship | Upselling stays within the same product line | Cross-selling spans related but distinct products. |
Upselling enhances the product; cross-selling enhances the overall shopping experience.
3- Use Cases of Upselling and Cross-Selling at Starbucks
1️⃣ Make Offers Obvious and Valuable
Starbucks doesn’t suggest random items — they recommend products that naturally complement the customer’s order.
- Cross-sell example: When a customer orders a latte, the barista may suggest a pastry or cookie.
- Upsell example: Suggest upgrading a medium drink to a venti or adding an extra espresso shot.
💡 Lesson: Choose items that enhance the main purchase, making the offer an easy “yes.”
2️⃣ Price Strategically
Starbucks keeps cross-sell and upsell items affordable relative to the main purchase, reducing decision friction.
- Cross-sell items (like pastries) are usually less than 30% of the drink price.
- Upsells (like size upgrades) are small incremental costs, making the upgrade feel low-risk.
💡 Lesson: Pricing should feel like a small step for a meaningful gain.
3️⃣ Keep It Simple
Starbucks knows that too many choices = no choice at all. That’s why they only suggest one or two add-on items when you order.
What this means for you:
- Show 1–3 cross-sell or upsell items at a time — never more.
- Pick the items that are most relevant and most likely to convert.
- Avoid overwhelming customers with long lists of extras.
💡 Lesson: A simple, focused offer makes the decision easy — and easy decisions convert better.
4️⃣ Timing Is Everything
Starbucks recommends add-ons after the main product is selected, not before.
- In-store: The barista asks about pastries or upgrades after the drink order is confirmed.
- Mobile app: Suggestions for syrups, toppings, or size upgrades appear during checkout.
💡 Lesson: Present offers when customers are committed to purchase — they’re more likely to accept.
5️⃣ Personalize the Experience
Starbucks uses both in-store insights and mobile app data to make offers relevant.
- Loyalty program data suggests favorite items, seasonal favorites, or commonly paired products.
- Personalization helps customers feel the offer is custom-tailored to them, not random.
💡 Lesson: The more relevant the upsell or cross-sell, the higher the acceptance rate.
Conclusion
Cross-selling and upselling are simple ideas, but their impact on customer experience and revenue is huge when executed well. The key is relevance, timing, and clarity. When you offer customers only what truly enhances their purchase—whether it’s a better version of what they already want or a complementary item that improves their outcome—you increase satisfaction and conversion.
Businesses that keep their offers focused, helpful, and easy to understand consistently outperform those that overload customers with choices. In the end, effective cross-sell and upsell strategies aren’t about selling more—they’re about helping customers get more value, and the sales naturally follow.
