Woocommerce Upsell Popup: Two Smart Ways to Increase Average Order Value

You set up your store in a solid way, but customers are not adding more items to their cart.

Yeah, we’ve all been there.

Most shoppers won’t go for add-ons unless you show them clearly.

That’s where WooCommerce upsell popups come in. 

Research from Upsell Guru shows that upselling can increase revenue by up to 30%. 

In this post, we will share how to offer a WooCommerce upsell popup that actually converts.

What is Woocommerce Upsell Popup?

A WooCommerce upsell popup is a powerful marketing strategy that boosts sales and increases order value by recommending complementary products to customers during their shopping journey. 

These popups can be strategically placed at two key moments: 

• Before checkout in the side cart 
• And after a purchase, as a one-click upsell.

Here are more details: 

1. Before checkout in the side cart

When customers add any item to their cart, you can show a pop-up upsell in a mini side cart with an option for users to add items to their cart with a single click. 

Usually, in such mini carts, users can see all the order details, including the order total, making it easier to make decisions. 

Example: When a customer adds a shirt to their cart, suggest matching pants, a stylish belt, or a coordinating cap to complete the look!

This approach highlights relevant products and enhances the shopping experience by making it easy for customers to consider add-ons.

2. After checkout as a one-click upsell

You can also display a one-click upsell offer pop-up right after checkout. This is a highly effective tactic because the users are already in the buying momentum. 

Plus, One-click upsells don’t require users to re-enter payment details, making it convenient for them to add items to their cart with just one button click. 

Example: After buying the shirt, you can offer matching pants and stylish shoes as upsells. 

Now that you understand how the WooCommerce upsells popup works, move on to the next section to learn about its benefits. 

WooCommerce upsell popups boost sales by increasing average order value, improving conversion rates, and clearing out inventory. In addition, it enhances the shopping experience with smart, personalized suggestions.

Let’s have a quick look at some of the best upsell plugins. 

Top WooCommerce Upsell Popups Plugins: Quick View

Expert's recommendations:

Experts recommend the FunnelKit plugins, both FunnelKit Cart and FunnelKit Funnel Builder. 

With these two combinations, you can offer upsells throughout the shopping journey. With FunnelKit Cart, you can offer upsells right after users add an item to their carts. Then again, with FunnelKit Funnel builder, you can offer a one-click upsell right after checkout. 

Plus, like other plugins, you can offer low-dollar upsell offers on the checkout page as well. 

And the reason why our experts recommend FunnelKit goes beyond upselling. With this tool, you can transform the default WooCommerce checkout page into a conversion-optimized one that reduces the cart abandonment rate. 

Move to the next section to find out how you can use these recommended plugins to offer WooCommerce upsell popups. 

Method 1: How to Offer WooCommerce Upsell Popup Using a Side Cart?

Here, we will show you how to recommend a WooCommerce upsell popup on a side mini cart. 

For this process, we will use FunnelKit Cart (both free and pro). You will get the pro version of FunnelKit Cart with FunnelKit Funnel Builder Plus and above.

As mentioned earlier, the FunnelKit Cart is a side cart that users can access from anywhere on the site, view their order details, and also update cart items. 

The best part is you can offer product suggestions on the side cart so users can add them to their cart with a single click. 

Ensure the FunnelKit Cart is installed and activated to follow this section.

Step 1: Turn on the slide-in cart by FunnelKit 

The first step is to enable the side-in cart. To do so, navigate to Funnelkit ⇒ Cart and turn on the  “Enable Cart” toggle button.

Step 2: Enable the upsell popup on the side cart 

Next, we need to enable an upsell pop-up on the side cart. To do this, go to the Upsells tab and turn on the “Enable Cart Upsells” option.

Step 3: Manage cart upsell settings 

Now, choose the display type. You get five different options to display your upsells. 

After choosing how you want to display your recommended products, customize the following:

• Product Recommendation Type: Recommend product upsells cross-sells, or both. 
• Heading: Provide the heading above the product recommendation section. The default option is "Frequently Bought Together".
• Show Maximum Upsells: set the maximum number of products you want to display as upsells.

Step 4: Add default upsells

Next, we will set the  “Default Upsells” that will show up as an upsell popup in case the cart items don’t have any upsell products assigned to them.

You can just search products by name and add them to the default upsell in WooCommerce.

You can add as many upsell products as you want, but the “show maximum upsells” option will limit the number of items on the front end.

Step 5: Set up individual upsells and cross-sells

FunnelKit Cart provides a sleek interface that allows you to add upsells and cross-sells from the cart setup page. This way, you don’t have to go back and forth to each WooCommerce product. 

To add upsell or cross to any product from the Funnel Cart page. Expand any of the products, then hit “Add Upsell”. Then, search and add the product. Repeat the same process to add cross-sell products. 

If you are looking for products that are not on the list shown, click on the “View All Products” link.

After that, you will find a sleek interface where you can either scroll down to find the product or search for the product using the search option. After that, expand the product section to add more upsells.

Once you set the upsell popup design and upsell offers, make sure to Save the changes.

That's it. That is how you can offer upsells on a side popup to boost AOV. Move to the next section to find out how to offer an upsell after checkout.

Method 2: How to Offer WooCommerce Upsell Popup Right After Checkout?

We are going to use FunnelKit Funnel Builder today to offer a one-click upsell right after checkout in WooCommerce. 

Before we create a WooCommerce one-click upsell funnel, let’s install and activate FunnelKit Funnel Builder. 

FunnelKit has two versions: Free and Pro. You need to install both.

Step 1: Create a store checkout 

Navigate to FunnelKit ⇒ Store Checkout from the WordPress admin panel and click the ‘Create Store Checkout’ button.

Now, choose your favorite page builder. From the list of funnels, hover over the one you like and click on Preview.

 We are going with Elementor and Shoppe here. 

After choosing the template,  select the type of checkout you want: one-step or multi-step. To import the funnel, click on the “Import This Funnel” button and provide a name.

Finally, clicking on ‘Done’ will import your sales funnel with the upsell template.

Now, you can customize the checkout page according to your preferences and also optimize it to reduce cart abandonment. 

Step 2: Customize the one-click upsell template 

To add a product as a one-click upsell, click on the "Offer" step.

No, you can hit the “Edit Elementor Template” option to customize the upsell template.

Step 3: Add your one-click upsell offer 

Next, to add the upsell offer, move to the Products tab, then click on “Add” product, and like you added products to the checkout page, add the product as an upsell.

Offering discounts on your upsell offers is a good marketing strategy, as it will make the offer more tempting to users. 

You can offer multiple upsells or downsells if you want. 

Step 4: Add conditions to make the upsell offer more relevant 

Another trick to make people buy upsell offers is to ensure the upsell offers are super relevant. You can make a one-click upsell relevant by applying different conditions using FunnelKit Funnel Builder. 

For this, hit the Upsells option.

Then, hit “Add New Rule” and set different rules based on product item, order details, customer details, etc, to make the offer relevant. 

For example, here, we set a condition to offer the upsell only if the customer purchased any item from the beauty category. 

For more details, check our documentation on upsell rules or watch this video

Make sure to save the offer after setting it up. 

Step 5: Enable store checkout 

The final and last step is to enable the store checkout, so it replaces your default checkout with a custom one and offers an upsell right after the checkout. 

Here is a preview of the WooCommerce upsell pop-up offer after checkout.

That’s how easily you can offer a WooCommerce upsell pop-up after a successful checkout.

5 Best Practices of Upsell Popup in WooCommerce 

To make sure your WooCommerce upsell popups are successful, follow these tips: 

• Target relevant product

Make your upsell offers relevant to the items in the customer’s cart. For example, if someone adds a laptop, suggest a sleeve or an extended warranty as an upsell. You can use FunnelKit’s rules feature to ensure your offers are always relevant.

• Use clear messages and images for attention

Keep your message short and direct. Use a compelling image to draw attention. FunnelKit Cart’s upsell templates help you place these offers right, and with one-click upsells, you can customize the design using your preferred page builder.

• Give customers enough upsell options

Don’t just offer one or two products. Present multiple relevant upsells across different price points. One-click upsells and downsells let you show alternatives if the first offer is declined.

• Offer milestone-based rewards

Use milestone-based rewards in your side cart upsells to increase order value. Encourage users to spend more to unlock a reward. FunnelKit Cart lets you offer free shipping, discounts, or free gifts as rewards.

• Add urgency with limited-time offers

Create urgency with countdown timers and limited-time discounts. FunnelKit Funnel Builder includes upsell templates with timers to boost conversions.
