Cross-selling techniques in mobile apps that actually work

One of the most profitable ways to increase revenue in e-commerce is not to attract more traffic, but to raise the average order value. Cross-selling techniques in e-commerce apps are a decisive tool for achieving this: when applied correctly, they can increase the average ticket by between 20% and 40% (McKinsey). And in mobile apps—where users buy faster, with less friction and more frequently—cross-selling works even better.

This article explores cross-selling tactics that really deliver results, how to apply them seamlessly, and what data to analyze to optimize them. We'll also look at how Inside, the clothing, shoes, and accessories store, maximizes its average ticket size and customer loyalty thanks to smart cross-selling strategies within its app.

1. Why cross-selling is more effective in apps than on the web

Mobile apps facilitate cross-selling because:

  • They offer a more personalized experience based on behavior and previous purchases.
  • Reduce friction: a single tap can add products to the cart.
  • They better capture intent: users enter the app already predisposed to buy.
  • They allow dynamic recommendations to be displayed at different points along the journey.

According to AppsFlyer, well-optimized apps achieve an average ticket price that is 28% higher than that of mobile websites.

Why cross-selling is more effective in apps than on the web

1. Additional recommendations on the product sheet

This is where the user has the strongest intent. You should display products that expand or enhance the main item:

  • "Complete your look," if you sell fashion.
  • "Compatible products" for electronics.
  • "Other customers also bought."

These recommendations increase conversion on the product page by up to 15%.

2. Cross-selling in the shopping cart

The user has already made a decision. This is the area with the highest conversion rate for recommendations:

  • Accessories in the same style.
  • Care or maintenance products.
  • Recurring items: socks, basics, accessories.

The shopping cart is where cross-selling generates the greatest increase in average ticket size.

3. Smart packs and combo deals

Packs are one of the most effective tactics in the retention and activation cluster because they encourage the purchase of additional categories.

  • Complete look package.
  • Discount for adding a second related item.
  • 3-for-2 promotions within the app.

Combined offers can increase AOV by between 12% and 30%.

4. Personalized cross-selling with behavioral intelligence

Using browsing data, previous purchases, and favorite categories, the app can display hyper-relevant recommendations without the user feeling intruded upon.

According to Segment, advanced personalization can increase revenue by 40%.

5. Push notifications designed for cross-selling

Push notifications are key when applied with intention and segmentation. Examples:

  • "You just saw this jacket. Would you like to see the sneakers that go best with it?"
  • Return to your wishlist: new combination available.

The CTR for these push notifications can exceed 20%.

6. Cross-selling through micro-interactions

Microinteractions facilitate action:

  • Quick buttons to "add to pack."
  • Animations highlighting recommended combinations.
  • Contextual messages such as "This product is often sold with..."

They reduce friction and increase the acceptance rate of recommendations.

7. Recommendations for onboarding new users

A rarely used but highly effective tactic: displaying complete sets or categories that introduce the user to the world of products.

This strategy accelerates retention and increases the likelihood of repeat purchases.

3. How to implement frictionless cross-selling

The goal is not to force more sales, but to offer real value. For cross-selling to work, it must meet the following criteria:

  • Relevance: recommendations based on data.
  • Appropriate time: do not interrupt browsing.
  • Clarity: demonstrate concrete benefits.
  • Fluidity: add with a touch, no extra steps.

When these rules are followed, cross-selling increases conversions and improves the overall experience.

5. Metrics you should measure to optimize cross-selling

  • AOV (average order value): primary indicator.
  • CTR for product and cart recommendations.
  • Conversion rate of suggested products.
  • Impact on recurrence after activating cross-selling.
  • Pack acceptance rate.

Apps that optimize these metrics on a monthly basis achieve sustained improvements and a notable increase in their digital profitability.
