Once you are generating a steady volume of orders month over month, you are going to hit a wall where the baseline systems and out-of-the-box functionality that your eCommerce platform provides is no longer enough.

In order to have a unified, frictionless frontend experience for customers, you need more customization on the backend to handle all of the complexity. 

All of the major eCommerce platforms realize this. They have their own app stores filled with third-party apps and integrations. 

In this post, we are taking a look at some of the best eCommerce integrations to help you convert more browsers into buyers, including: 

Why Do You Need eCommerce Integrations? 

As your business scales, you’ll likely find that you need additional eCommerce integrations to support the following aspects of your business:

  • Checkout & Payments
  • Inventory
  • Order Management
  • Shipping 
  • Analytics 
  • Customer Reviews 
  • Marketing Automation
  • Social Media
  • Website Optimization
  • Customer Support 
  • Accounting & Finance 
  • Point of Sale System (POS) 
  • Enterprise Resource Planning (ERP) 

For example, if you are looking to increase average order value with post-purchase offers, you might use an eCommerce app like CartHook.

Or, if you are looking to streamline the process of returns management, you might use an app, such as Happy Returns.

And, if you are looking for an easier way to handle the complicated task of collecting and reporting sales tax in the U.S., you might use an app like TaxJar.

16 of the Top eCommerce Integrations 

With thousands of third-party eCommerce integrations available in just these four app stores, we curated a list of the top integrations from a couple dozen eCommerce marketers.

Note: Our list skews heavily towards Shopify apps and WooCommerce plugins, as that’s what the majority of the marketers we surveyed are using. 

  1. Magento 2 Amasty Out of Stock Notifications
  2. AutomateWoo
  3. Candy Rack
  4. EcoCart
  5. FenixCommerce
  6. Free Shipping Bar
  7. Google Analytics
  8. Honeycomb
  9. Klaviyo
  10. Lucky Orange
  11. MailChimp
  12. Segment
  13. Stamped
  14. Sticky Bar
  15. Tawk.to
  16. TRUST

1. Magento 2 Amasty Out of Stock Notifications 

“We integrated with the Amasty Out of Stock Notifications extension on the Mitchell & Ness website to allow customers to sign up to be notified when certain high demand products have been restocked in their size,” says Kevin Dugan of DMi Partners. “Since launching this functionality in September, we have generated 60,000 signups for notifications and generated over $300,000 in revenue from the back-in-stock emails that this extension sends.

We built the functionality to only allow an out of stock signup on certain “evergreen” products – primarily our authentic jerseys. When a customer’s size isn’t available, instead of seeing an “Add to cart” button, they see “Out of stock. Get notified, which brings them to a page to sign up for notifications for when their size is restocked.” 

2. AutomateWoo

AutomateWoo is a marketing workflow plugin for WooCommerce,” says Peter Jay of Inline Host Blogger. “It takes over repetitive tasks such as emailing reminders or sending abandoned cart emails. This frees your mind to grow your business. 

You can configure various types of popular marketing emails each with a custom subject, texts, etc. Each email-type follows the same workflow: Once configured and activated, the plugin then awaits the trigger (for example, a shopping cart being inactive for a few hours), loads the pre-configured text, replaces the placeholder with the customer information, and sends it off. Emails with custom coupon codes allow for tracking of the success as well.”

3. Candy Rack 

Candy Rack offers customers an upsell/cross-sell with promotions, so when they add an item to cart, they are offered relevant products or accessories they may like,” says David Reichmann of Rawrycat Pet Products. This has increased my conversion value by more than %80 on average.” 

4. EcoCart 

Austin Hirsh of The 2050 Co says, EcoCart is an app that plugs directly into any eCommerce store and offers your customers carbon-neutral orders by adding a few extra cents, which funds certified carbon offset projects.” 

5. FenixCommerce 

FenixCommerce uses your own data, shipping data, and even weather data to accurately predict the landed date of your products,” says Derric Haynie of EcommerceTech.io.

“Similar to Amazon’s Get it by X functionality, you can now tell customers exactly when they will get the product, especially crucial for Christmas-time. It’s been proven to increase conversion rate by over 15%. And it makes sense because if you know when you’re going to get it, you’re more likely to buy.” 

6. Free Shipping Bar 

Free shipping is a big motivator, and if you have a threshold at which you offer free shipping, making that salient can increase average order value as well as conversion rates,” says Alex Birkett of Everything But The Plant. “It’s quite simple: if you have a $50 threshold, above which you offer free shipping, then you can create a banner that nudges the user to add $X to their cart to reach that number.” 

7. Google Analytics 

Google Analytics is the most powerful tool you can use in eCommerce, whilst it doesn’t affect your conversion rate directly it gives you information on exactly where in your PDP->checkout prospects are dropping out and therefore guidance in what part of your funnel needs fixing to improve your conversion rate,” says Joshua Hill of Soseas. “If you aren’t looking at google analytics regularly you’re not measuring performance and what can’t be measured can’t be improved.”

8. Honeycomb 

Honeycomb upsells have been great,” says Daniel Chang of Z Group Digital. “Super easy to set up and a great dashboard for management. It increases the average order value by adding upsells, cross-sells, and down-sells. Some of our clients are generating $1k+ a week just by adding this plugin.”  

9. Klaviyo 

Klaviyo, a popular email marketing platform, has to be, by far, our top eCommerce integration for converting leads and customers,” says Carley Hanna of Supplement Warehouse. “Klaviyo is a tool that allows you to completely customize promotional and non-promotional emails to your entire customer base, or to select segments in your customer base.

Klaviyo also allows you to set up easy templates for automated emails to be sent.

For example, a company may want to send an automated follow-up email right after a customer has placed an order, 30 days after a customer has placed an order, or sent out sign-up sheets with more specific leads, etc. I’d recommend Klaviyo, or an email marketing integration of some sort to any eCommerce business. It’s a great and essential way to engage and connect with your customer base.”

10. Lucky Orange 

Lucky Orange is a conversion optimization platform,” says Jeff Stripp of Zogics. “It allows us to peek behind the digital curtain so we can see how prospective customers found our store, understand the actions they took once they landed on our website, and learn why they’re not converting.

We rely on Lucky Orange because it combines qualitative information (e.g. heat maps, live recordings, etc.) with quantitative insights (e.g. behavior tags, abandonment reports, etc.). This granular information allows us to turn our data into actionable steps to take in order to improve our conversion funnel and the user experience on our website.” 

11. MailChimp 

“One eCommerce integration we feel works best is MailChimp,” says Andrew Ruditser of Maxburst, Inc. “MailChimp is what we typically recommend to clients when they would like to easily grow their email marketing efforts. The reason why we feel Mailchimp works best is that you can simply connect your lists and create email opt-in forms.

It works great with eCommerce checkouts that will automatically add users to your mailing lists for future sale promotions.

Purchasing the premium is not necessary to use Mailchimp, but doing so will allow you to use other beneficial functionalities that will make it more worth it. This includes the ability to tag users based on the items they purchase, allowing you to create more personalized emails that spark their interest and hopefully continue to purchase more.” 

12. Segment 

“There are various ways through which you can integrate your eCommerce stores and one way to do so includes Segment that collects user events from your web & mobile apps and provides a complete data toolkit to every team in your company,” says Jennifer Willy of Etia.

“Use one API to collect analytics data, across any platform. We have SDKs for Javascript, iOS, Android, and 20+ server-side languages. It helps define the journey for a customer as they browse your store, click on promotions, view products, add those products to a cart, and complete a purchase.” 

13. Stamped 

“I recommend Stamped to all my clients and use it on my own stores too,” says Nicolas Fradet of Eestrad. “It’s bar down the best reviews integration for lifting sales, and I’ve seen double-digit conversion rate increases with it. Reviews are by far the #1 lever for more sales, yet most marketers are happy with Shopify’s default system, which is ok but falls short in many ways. 

Stamped lets buyers rate multiple features of your product so others can find the most relevant reviews for their needs, as well as send videos and photos for great user-generated content.” 

14. Sticky Bar

“We implemented the Sticky Bar WooCommerce plugin to display a highly visible banner at the top of our website to all new visitors only,” says Alexis Dollé of Mailbird. “We used it as a way to generate a welcome offer to encourage new visitors to buy our product. By offering them a promo for only one time and for only 3 hours, we were able to increase sales by 45% instantly.” 

15. Tawk.to

Tawk.to is a free live chat application that allows you to engage with customers in real-time,” says Bruce Hogan of SoftwarePundit. “This real-time support allows you to answer customer questions and build trust with shoppers – both of which improve conversion rates.” 

16. TRUST 

“I know that web users are wary about giving their credit card number and personal details to websites,” says Nikola Roza of Nikola Roza- SEO for the Poor and Determined. “And I know that if I want to get sales for my Shopify store I must dispel their fears completely.

I achieve that with TRUST app (Silver plan). Yes, it’s a bit expensive with a price tag of $60/month, but it gives me everything I need to show that my shop is a legit and safe business.

The features I use the most are importing reviews from other sites, having trust seals next to checkout buttons and on the checkout page, and showing social proof throughout the entire site via footer and also more prominently on the checkout page.

The key to shopping online is to let potential consumers know that other people have had a great experience with your product that they bought from your shop, and then sales will naturally follow.

Because users generally want to buy and only a strong reason (like lack of trust signals) would compel them not to.” 


In sum, as your eCommerce store grows, the systems and processes you need to keep everything running on the backend will become more complex.

All of the eCommerce integrations we shared above allow you to provide a great experience for customers while handling all of the complexity on the backend to fulfill and manage your orders.
