6 Best WooCommerce Upsell Plugins Compared 2025

In this post, you’ll discover our picks for the six best WooCommerce upsell plugins.

Implementing WooCommerce upsells is a great way to boost your store’s sales and improve your bottom line. But as you may have noticed, WooCommerce doesn’t include much built-in functionality for implementing upsells. 

Instead, you’ll need to turn to a WooCommerce upsell plugin if you want to implement the most effective upselling strategies.

Thankfully, you’re spoiled for choice when it comes to options, which is what we’re focused on in this article.

The 6 Best WooCommerce Upsell Plugins Compared

Before digging into our picks for the six best WooCommerce upsell plugins, here’s a high-level comparison of their features, pricing, and ideal use cases:

Now, let’s see the six best WooCommerce upsell plugins in detail.

1. Merchant Pro

Merchant Pro is not just a WooCommerce upsell plugin — it’s a full WooCommerce toolkit that comes with 47+ different modules that you can use to boost your store’s revenue and create a better shopping experience for customers.

All of these different features use a 100% modular approach, which means that Merchant will only load the specific modules that you enable and won’t add code for any features that you’re not actively using.

Within those 47+ modules, you get multiple different tools that you can use for WooCommerce upselling:

• Trigger an upsell popup after a shopper adds an item to their cart – In this popup, you can showcase products that are related to the item the customer just added to their cart. By upselling these additional related products, you can encourage shoppers to increase the sizes of their orders.
• Display “Frequently Bought Together” products to encourage shoppers to add more items – You can also offer discounts to incentivize customers to purchase extra items.
• Create bulk discount deals and upsell them on the single product, Cart, Checkout, and Thank You pages – Shoppers can easily increase the sizes of their orders to get the bulk discount. The Thank You page option even lets you create post-purchase upsells.
• Add “Buy X, Get Y” upsells to the single product page, Cart, Checkout, and Thank You pages – You can create any type of deal and promote it in various places on your site. You can even use it as a post-purchase upsell after a shopper places their order, in addition to the other placement options.
• Add a Shopify-style slide-out side cart that includes upsells – Not only does the side cart create a great shopping experience, but you can also use it to promote related products and other upsell offers.

And again, beyond all the various upselling features, you can also access dozens of other features in a 100% modular manner. While these features span a range of different functions, you might be especially interested in the discounting features, as these can pair well with upsells. You can create various types of discounts such as storewide sales, free gifts, product bundles, and more.

Price: Merchant does have a free version at WordPress.org. However, many of the upselling modules require Merchant Pro. Merchant Pro starts at $79 for use on a single site and one year of support and updates.

There are also lifetime licenses available, which can reduce your long-term costs. These start at $249 for use on a single site and lifetime updates.

2. Fast Cart

Fast Cart helps you upgrade the default WooCommerce cart and checkout experience, including adding the ability to more effectively include upsells on those pages.

For example, you can display related products in users’ shopping carts, which gives you a chance to upsell those products to your customers and increase the size of their orders.

You can choose to automatically display the shopping cart as a floating box after a shopper adds an item to their cart. Or, you can trigger it with a button click instead.

Shoppers can complete their purchases directly from the floating cart. The plugin also includes other features to reduce checkout friction, such as address autocomplete.

Overall, Fast Cart can be a good option to consider if you want the ability to add upsells to the cart and checkout process. However, if you’re looking to add other types of upsells, such as an upsell popup, you might prefer a different plugin on this list.

Price: Fast Cart only comes in a premium version. Plans start at $79 for use on a single site.

3. YITH WooCommerce Frequently Bought Together

As the name suggests, YITH WooCommerce Frequently Bought Together helps you create Frequently Bought Together product upsells to encourage shoppers to purchase additional products.

You can promote these Frequently Bought Together products on the single product page. Shoppers can then easily add some or all of the products to their cart using simple product checkboxes.

The plugin also integrates with some other YITH plugins. For example, if you’re using YITH’s wishlist plugin, you can upsell products in the wishlist interface.

To control which products to promote, you get multiple options, including both manual and automatic product selection:

• Related products
• Cross-sell products
• Upsell products
• Custom product selections

You can also choose whether to show all of the products or randomly select a certain number to promote, as well as whether to offer a discount on the products.

Overall, this plugin can be a good option to consider if your main goal is to upsell relevant products on single product pages. However, it lacks other upsell strategies, such as the ability to display upsell popups or set up post-purchase upsells.

Price: There’s a basic free version of the plugin at WordPress.org, but it lacks some important features, such as the ability to automatically suggest upsell products. If you want all of the plugin’s functionality, paid plans start at €79.99 per year for use on a single site.

4. UpsellWP

UpsellWP is a dedicated WooCommerce upselling plugin that can help you implement a variety of different upselling strategies, with some similar strategies to the Merchant Pro plugin above.

If you pay for the premium version of UpsellWP, you can access the following types of upsell tactics:

• Cart, Checkout, and Thank You Page upsells – You can display your upsell offers on these key pages to encourage shoppers to increase their order sizes.
• Frequently Bought Together deals – You can display these products on the single product page, as well as in other areas.
• One-click “Double Your Order” option – You can offer a special discount if shoppers double the size of their orders, which they can do with a single click.
• Upsell popups – You can trigger an upsell popup after a shopper adds an item to their cart or goes to the Checkout page.
• Product recommendations – You can display related or recommended products based on a variety of conditions.

The premium version also lets you run A/B tests to find which upsell offers are the most effective, which is a unique feature on this list.

Price: UpsellWP does have a “lite” version at WordPress.org. However, if you want to access all of the features, the paid version starts at $69 for use on a single site and goes up to $199 for use on up to 25 sites.

5. Sales Booster for WooCommerce

Sales Booster for WooCommerce is a premium WooCommerce upsell plugin from IconicWP, a WooCommerce development shop that was acquired by Liquid Web/StellarWP back in 2021.

It helps you implement a variety of different upsell and cross-sell strategies designed to boost your store’s revenue.

Here are some of the different tactics you can implement:

• Frequently Bought Together products – You can display these on the single product page for some or all of your store’s products.
• Add to cart popup – You can show a popup after a shopper adds an item to their cart. In this popup, you can promote other products that you manually choose.
• Checkout page cross-sells – You can display a related product on the Checkout page and let shoppers add it to their order with the check of a box.
• Post-purchase cross-sells – You can show a popup after a shopper completes their order that lets them add an item to their existing order with a single click.

For each type of upsell or cross-sell, you get a good number of options to configure which products to display and how to promote them.

Price: Sales Booster for WooCommerce only comes in a premium version (there are some similarly named free plugins at WordPress.org, but those come from different developers). The license starts at $79 per year for use on a single site and goes up to $489 per year for use on up to 30 sites.

6. FunnelKit

FunnelKit is a heavy-duty WooCommerce sales funnel builder that can also help you create upsell offers as part of its functionality.

This plugin is still based on WooCommerce, but it’s more suited to people looking to sell products via dedicated sales pages, rather than a more traditional eCommerce layout.

To start, it helps you create a standalone sales page for each product that you want to sell, either via the native WordPress editor (Gutenberg) or its page builder integrations.

Here’s an example of what it might look like, in case you’re still a bit confused about the difference between FunnelKit’s sales pages versus a “normal” eCommerce store. This screenshot also shows how there are multiple cohesive pages in the funnel:

Then, you can create sales funnels with various upselling strategies, including the following:

• One-click upsells – You can add a product upsell to the checkout flow and let shoppers upgrade their orders with a single click.
• Order bumps – You can add an “order bump” to the checkout, which essentially lets shoppers add a related item by ticking a box on the Checkout page. You can choose which product to display using rules based on the shopper’s cart items, purchase history, and more.
• Post-purchase upsell offers – You can display an upsell offer after a shopper completes their order. They can then easily add these item(s) to their order. As with order bumps, you can choose which products to display using conditional rules.

Overall, FunnelKit could be a good option if you want something that can help you create entire sales funnels, from the product sales page all the way through to the custom checkout flow.

However, if you want to use a more “standard” eCommerce layout with regular single product pages rather than sales pages, you might want to choose a different plugin.

Price: FunnelKit has a limited free version at WordPress.org, but you’ll need the paid version to access a lot of the upselling functionality. The premium version starts at $129 for use on a single site and ranges up to $599 for use on up to 30 sites. The developer also regularly runs large promotions that will discount your first year by ~50% (but your license will still renew at regular price after the first year).
