The Best Upsell App for Shopify

If you operate an eCommerce brand, you probably care a lot about your average order value, or AOV. If not, you should. Upsells increase AOV. They can also help move excess inventory/ Upsells can exist on product detail pages, encouraging customers to buy in quantity, add accessories, or purchase bundles instead of single products. They do so reliably, and can be implemented in ways that are non-obtrusive and organic. Done correctly, upsells increase your top-line revenue without changing your conversion rate or ad spend. The three most common upsells are:

  1. Recommending accessories for a flagship product.
  2. Recommending popular products on carts
  3. Bundle upgrades for products that happen to be a component of a larger bundle – or bundles that can be upgraded to bigger bundles.

It’s important that upsells are introduced to customers with thoughtful, deliberate optimization, especially if you operate a luxury brand. If you’re using Shopify, we really like the Rebuy app, as it allows for rule-based logic with different recommendations and positioning based on the cart contents. Using Rebuy allows you to upsell to your customers in a few places: homepage, PDP, cart, checkout. One key thing to consider when using is making sure the product recommendations load quickly, as this is one issue you see quite a lot with examples using third parties for recommendations (waiting for the Javascript to load). Ensure that your Shopify developer is experienced enough to make sure your store performance doesn't suffer as a result of adding the Rebuy app.

Other good options to consider are One Click UpsellCheckout Promotions & Upsells and Orderbump (for Shopify Plus only)

Where to Put Upsells

  1. On a product page. This is especially good for subscriptions or bundles. "Complete the look" is a great way to display this upsell on the PDP. If you're selling items that can come in a set, this will be the easiest way to cross-sell a bundle. AI generated recommendations are also a great option. Last but not least, one of the favorite feature I love from Rebuy is their AI recommendations. Based on data sets that they collect from being on your site, this widget on your website will show products that the AI thinks your customers will pick.
  2. On a cart page/drawer. This is the most common place to put upsells. When using Rebuy for our clients, we like to add a "frequently bought together" section. Rebuy is custom design-friendly, so it's easy to make it look on-brand with your cart. We’d suggest trying to really justify the up-sell within the accompanying wording, helping to make them feel more curated or personalised. Most well-optimised cart drawers will feature product recommendations and in our experience, obvious up-sells can achieve up to a 20% add to cart rate.
  3. On a checkout page. This can happen, but most of the time you want to keep the customer focused on filling out the form. Checkout pages are good for warranties or insurance, though. If you're on Shopify Plus, you're gonna love this You can add a section to cross-sell products at the checkout page. We found this to be the sweet spot to cross-sell since buyer intent is very high
  4. After checkout, and before the thank-you page. This is called a post-purchase upsell. 
  5. In an email after purchase. This will likely result in a second shipment – but it’s good for encouraging subscriptions and repeat purchases. Rebuy has a feature that is called "Smart Cart Push to Subscription". If your product can be repurchased, you can incentivize your customers to subscribe and save — increasing subscriptions can lower your CAC (customer acquisition cost). If you have a luxury website design, lowering your CAC is something that you should strive to do.


How do you pick the best products to upsell?

First, review your store's order history. What products are frequently purchased together? Are there any pairings that surprise you? Make sure that any upsells you have look familiar, that the terms are clear, and that the customer is fully aware of what they're getting and why. We hope this guide helps you understand the needs of your customers.

As a result, with post-purchase upsells, as with everything else, you should carefully evaluate their appropriateness, test their existence, and optimize them over the long term. Please be thoughtful about where you introduce upsells to your customer; you can’t put a price on your brand's long-term reputation. With these tactics in place, you should be able to make upsells a more conscious part of your optimization strategy – and create a system that promotes the right products at the right time.
