Cross-selling

What is cross-selling?

Cross-selling is a sales strategy where you suggest additional, complementary products to a customer based on what they are already buying. The goal is to broaden the basket, not upgrade the item, helping customers discover relevant add-ons they would have wanted anyway and increasing the total order value in the process. It is one of the most common revenue tactics across ecommerce, retail, and subscription businesses.

A familiar example is Amazon’s “Frequently Bought Together” block, which suggests products other shoppers added alongside the one you are viewing.

What is the difference between upselling and cross-selling?

Both tactics aim to grow revenue per customer, but they work differently:

• Cross-selling suggests related or complementary products (e.g., “Add a cleaning kit to your lens order” or “Customers also bought a phone case”)
• Upselling suggests a higher-end version of the same product (e.g., “Upgrade to the Pro camera for $100 more”)

In short: cross-selling broadens the basket, upselling deepens a single item. Many stores use both at the same time, for example offering a higher-tier mattress (upsell) and matching pillows (cross-sell) on the same page.

Why is cross-selling important?

Cross-selling improves the shopping experience by anticipating customer needs and offering convenience. For businesses, it is one of the most reliable tactics for increasing average order value (AOV), which in turn lifts revenue and lifetime value without any additional ad spend. Selling more to an existing customer is consistently cheaper than acquiring a new one through paid channels.

What are effective cross-selling strategies?

Cross-selling works best when the recommendation is genuinely relevant and shown at the right moment:

• Display related products on the product page and inside the cart
• Use “Frequently Bought Together” recommendations and product bundles to package complementary items
• Offer add-ons or small upgrades during checkout, where purchase intent is highest
• Send personalized post-purchase emails recommending refills, accessories, or matching items
• For subscription brands, surface refills, support items, or one-time add-ons inside the customer portal so they ship with the next renewal

The recommendation should feel useful, not pushy. Personalizing offers based on past purchases or browsing behavior typically converts better than a generic add-on list.

Example of cross-selling in ecommerce:

A customer buying a shampoo subscription is shown a matching conditioner as a recommended add-on before checkout. After the order ships, a follow-up email suggests a leave-in treatment from the same line as their next shipment add-on. Both touchpoints are cross-selling: the original purchase stays intact and complementary products are added around it.

Driftcharge Tip

The strongest cross-sells feel like helpful suggestions, not interruptions. Start with two or three genuinely complementary products that share usage, occasion, or theme with what is already in the cart, then test placement (product page vs cart vs post-purchase email) to see which triggers the largest lift in average order value for your store.
