Cross Sell

A cross-sell is an offer that suggests a related product to go with what a shopper is already buying. A phone case with a new phone is the classic example. It adds items to the order and helps customers get everything they need in one purchase.

How cross-selling works

You pair products that are used together and show the pairing while the shopper is buying. Good cross-sells are:

• Complementary. The add-on makes the main product more useful.
• Lower in price than the item already in the cart.
• Easy to add, ideally in one click.

Cross-sell vs. upsell

A cross-sell adds a different product. An upsell offers a better or bigger version of the same one. Our upsell and cross-sell guide explains when to use each.

Where to show cross-sells

• Product page. "Frequently bought together" and "pairs well with" sections.
• Cart. Small add-ons, especially ones that help reach free shipping.
• Checkout and post-purchase. One relevant extra.
• Follow-up email. A refill or accessory after the first order arrives.

The Rebuy Smart Cart shows personalized cross-sells inside the cart, based on what each shopper has added.

How to choose what to cross-sell

Start with your order data: which products do customers already buy together? With a small catalog you can set pairings by hand. With a large one, AI recommendations do the matching for you.

Cross-sell FAQs

What is an example of cross-selling?

A shopper buying running shoes is offered socks and insoles. A shopper buying a coffee maker is offered filters.

What is the difference between cross-selling and bundling?

A cross-sell is a suggestion the shopper can add. A bundle packages the products into one offer, usually at a combined price.

How many cross-sells should I show?

One to three. More choices make it less likely a shopper picks any.
