WooCommerce Checkout Add-Ons: How to Use Them to Optimize Your Store and Increase Sales

WooCommerce checkout add-ons like order bumps, upsells and cross-sells are a great way to boost the average order value in your store.

Many eCommerce giants, like Amazon, eBay, Alibaba, etc., make complementary offers on the checkout page to boost their AOV.

Did you know Amazon makes 35% of its revenue through upselling and cross-selling?

That’s the impact checkout add-ons have on an online store.

In this article, you will learn how to:

  • Add one-click order bumps 
  • Suggest upsell offers

These powerful add-ons enhance your customer’s checkout experience and increase your store’s AOV at the same time.

Furthermore, we’ll also look at some of the great WooCommerce checkout add-on plugins to set up compelling add-on offers within minutes.

What are WooCommerce Checkout Add-Ons?

WooCommerce checkout add-ons are additional features or extensions that can be integrated into the checkout process of your WooCommerce store.

It helps expand your online store’s functionality during the checkout, enhance the shopping experience and provide additional customization options for shoppers.

Here are some examples of WooCommerce checkout addons:

  • Additional fields - Using the checkout add-ons, you’ll be able to add custom fields to the checkout page. This further enables you to gather specific information from your customers during the checkout process. It can include special instructions, gift messages or wrapping options, etc.
  • Upsells and cross-sells - These add-ons allow you to offer product recommendations to users before or after they finalize their purchase in the form of cross-sell and upsells. For example, it can include extended warranties, higher-priced alternatives, items that complement the items within the cart, etc.
  • Delivery date and time - Such add-ons enable the customers to select a preferred delivery date and time for their order on the checkout page. These add-ons are quite helpful for businesses that offer delivery or book appointments.
  • Payment gateways - WooCommerce checkout add-ons for payment gateways lets you integrate your store with additional payment options to provide a seamless checkout experience to your customers. It helps you provide your customers with their preferred payment methods, which further reduces cart abandonment.

Let’s look at a checkout add-on example from Z Grills:

Example of WooCommerce checkout add-ons

It has the “Upgrade to Gold Warranty” offer as their order bump. Order bumps are the pre-checkout offers that help boost your store’s AOV with a single click.

Then there are upsell offers - these are the offers made after the sale is completed. Post-purchase upsell offers perfectly complements the primary purchase, and that is what would make them hard to reject.

For example, let's say you sell online courses, and a customer is on their way to buy your "Basics of Cooking" course.

You can display an upsell offer by nudging them to buy your "Masterclass Course", which will teach them the basics along with how to make a particular type of cuisine.

Why Do You Need WooCommerce Checkout Add-Ons?

As a WooCommerce store owner, you must optimize your WooCommerce checkout page to squeeze more profits from the same sale.

WooCommerce checkout add-ons are tested and proven ways to encourage your customers to spend more at the checkout without being too salesy.

Here are a few reasons why you should add add-ons to your store’s checkout page:

1. Increase AOV by 10%-30%

An average order value (AOV) is the average amount a user spends on your site when they make a purchase.

AOV can be used to determine how much you can spend to acquire a customer and still make a profit. Also, it dictates which marketing channels to use.

According to WakeUpData, using relevant order bumps can boost your AOV by 10% – 30%!

On the other hand, a study concluded that 3 out of 4 salespeople who did upsell or cross-sell saw a 30% growth in their revenue.

2. Take advantage of the user’s attention span

A checkout page is the most important page of your online store; therefore, a user’s attention span is quite high here. So, it makes a lot of sense to present them with order bumps and upsell offers.

If the upsell offer or the order bump is declined, you can even present a cross-sell or a downsell offer.

Since the attention is at the highest, users will consider these offers seriously and might even add them to their cart.

3. Enhance the checkout experience

WooCommerce checkout add-ons enhance the customer’s checkout experience by suggesting relevant complementary items.

Another example is the mini cart checkout add-on that allows users to view or update the quantity of a product in their shopping cart before the purchase.

These add-ons will help enhance the checkout experience for your shoppers and make way for an effortless buying process.
