Thousands of online stores use various ecommerce apps to optimize several functions of their business, including shipping, marketing, and customer relationship management. For example, many apps can help your business enhance your customers’ experience; this is crucial because 76% of people will stop working with an organization after only two bad experiences. So, you can probably see how these apps can help improve your business.

The “Big 4” ecommerce platforms consist of Shopify, WooCommerce, BigCommerce, and Adobe Commerce (Magento), and it’s safe to assume that you’re using one of them to operate your business. You can implement many apps and plug-ins in your online store to help you automate and enhance your ecommerce presence and increase efficiency. If you’re searching for ways to grow your business, keep reading because I have some of the top ecommerce applications that are worth checking out.

How I Selected the Best Ecommerce Apps

Perhaps you're wondering how I selected the best ecommerce apps for this list? To build this top 10 list, I evaluated and compared a wide range of ecommerce apps with positive user ratings.

After determining my long list of top choices, I further honed my list by using the selection criteria below to see how each platform stacked up against the next one. I also drew on my years of ecommerce experience to pinpoint the features that add a lot of value.

If you have general questions about ecommerce apps or how to pick the best ecommerce apps for your organization, take a look at our frequently asked questions section below. Or, you can skip directly to my detailed software summaries, if that's what you need the most.

Selection Criteria

Here’s a short summary of the main selection and evaluation criteria I used to develop my list of the best ecommerce apps for this article:

Usability:

Usability all boils down to your experience when using an ecommerce app. An application that provides you with an excellent experience can be the deciding factor on whether you want to use the app again. I look for ecommerce apps that are easy to navigate when searching for specific functions or information.

Mobile Friendly: 

You or your team members might need to access your ecommerce store through a mobile device. So, a mobile-friendly application will be crucial to allow everyone to access the app’s vital functions from whatever device they use. I look for ecommerce apps that work on any mobile device so you can understand what’s going on and make any necessary adjustments while on the go.

Customer Service: 

If you ever have difficulties using any of these ecommerce applications, it’s good to know that the vendor has a customer service team to help solve them. I look for applications with a customer service team working behind the scenes to help online stores like yours and ensure you have all the information you need to properly use the app. It’s also helpful if the customer service team can respond to your questions immediately.

Software Integrations: 

Ecommerce apps should work well with the current systems you’re using to manage the storefront from outside the platform. For example, you might already use software such as HubSpot to manage customer relations. It’s beneficial to use an ecommerce app that can send vital customer information to your HubSpot platform to save you and your team from entering the data manually.

Pricing:

The price you could pay to use an ecommerce app should reflect the value you gain from using it in your store. Some might have a “free forever” subscription tier or a free trial to help you see the value for yourself and convince you to continue as a paid customer. I look for apps that have reasonable subscriptions and low or no setup fees.

Yotpo has strategic partnerships with Facebook and Google to make it simple for your business to include star ratings from Google AdWords and Product Listing Ads.

Amazon Pay works on all the Big 4 ecommerce platforms, and it’s very easy to sign up and integrate the app into your online store.
