When you’re running an ecommerce business, you’re juggling a lot: designing your brand, building your website, managing inventory, processing orders, figuring out how to reach customers, and more.
But before you can tackle any of that, you need to pick your ecommerce platform. And that choice affects everything else. It determines what integrations you can use, how you access and use customer data, whether you can scale as you grow, and how much you'll pay in transaction fees and platform costs.
According to G2, there are over 500 ecommerce platforms to choose from, ranging from simple website builders to comprehensive commerce suites.
Ecommerce platforms handle product listings, inventory management, check-out, payment processing, and a lot more. And the best ones make it easy to build your website and manage your business operations together, so you can focus on growth.
What are the benefits of using an ecommerce platform?
Ecommerce platforms help you manage your day-to-day operations, maintain a top-notch customer experience, and access insights from your customer data. Here are some of the benefits of using one to grow your ecommerce business:
- You control your customer data. Unlike selling exclusively through marketplaces, running your own ecommerce store means you control customer information. This ownership gives you the freedom to use that data however you need, like sharing it with other tools to influence marketing and customer service, analyze buying patterns, build custom reports, and more.
- You can build a solid brand identity. Ecommerce platforms give you the freedom to curate everything from your storefront design and product pages to your check-out experience and post-purchase emails. When customers see consistent branding every time they interact with you, it helps build trust. And people are willing to pay for that: 87% of customers will pay more for products from brands they trust, according to Salsify’s 2025 Consumer Research Report.
- You can access user-friendly tools that help handle complex tasks. Modern ecommerce platforms have built-in AI and automation to speed up tedious tasks, optimize your marketing efforts, and keep your inventory in check. Instead of managing spreadsheets and manual processes, you can automate the operational work and focus your time on strategy, growth, and customer relationships.
19 of the best ecommerce platforms
We’ve compiled a list of 19 ecommerce platforms that integrate with Klaviyo, ranging from well-established solutions to specialized platforms built for specific industries and business models:
Shopify
Shopify is one of the most well-known ecommerce platforms, supporting shops for companies ranging from small businesses to major enterprise brands. The platform handles product listings, inventory tracking, payment processing, order fulfillment, and more.
Shopify's app ecosystem lets you add functionality across marketing, service, payments, and sales, and its built-in POS system connects your online and in-store retail operations. Connect with verified suppliers to find products to sell and use Shop Pay to let customers place orders with one tap.
Klaviyo’s Shopify integration syncs order information as it happens: placed order, product details, customer profiles, behavioral data, the works. It lets you:
- Send commerce data from Shopify into Klaviyo to create a single source of truth that personalizes email, text message, mobile, and WhatsApp messaging.
- Combine engagement and commerce data to get AI-powered insights about high-value customers and purchase intent, and deliver targeted campaigns accordingly.
- Get access to real-time dashboards with recency, frequency, and monetary (RFM) scores and retention metrics.
When meal delivery service Daily Harvest’s heavily customized tech stack became too difficult to scale, they switched to Shopify and Klaviyo. Now, they no longer need developer help to complete basic marketing tasks, like sending and updating emails. They’ve also reduced their team’s ecommerce-related developer hours by over 15% and cut their ecommerce tech costs 18%.
WooCommerce
If you’re familiar with WordPress, WooCommerce is likely already on your radar. It’s an open-source plug-in that turns your WordPress site into a fully fledged online store, and it’s the most popular ecommerce platform option for WordPress users.
People love WooCommerce for its extensive customization options. You own your code and can modify anything, which makes it a good option for developers and brands that need specific features or workflows.
“Woo’s ecommerce platform comes with customizable and scalable features that empower stores of all sizes to launch, adapt, and grow their businesses,” says Joe Franger, former director of strategic partnerships at Automattic, the company that owns WooCommerce and WordPress.
“Open-source extension architecture enables users to add free or paid functionality from Woo’s marketplace or any compatible extension developed by the global Woo/WordPress community,” Franger adds.
With Klaviyo’s WooCommerce integration, you can:
- Sync real-time customer and order data easily from WooCommerce to Klaviyo, like browsing habits, purchases, and preferences.
- Send tailored marketing messages across channels that feel personal and relevant with dynamic product recommendations and coupons.
- Use pre-built templates for cart abandonment, welcome messages, and more.
One of the reasons eco-friendly cleaning brand Force of Nature switched to Klaviyo was its WooCommerce integration. “Klaviyo has a more seamless integration with WooCommerce than other platforms that I’ve seen,” says Andrea Jordan Kattan, lifecycle marketing strategist at Power Digital, Force of Nature’s agency.
BigCommerce
BigCommerce is designed to help high-volume stores and brands build, manage, and scale their online stores. It offers a range of features, including product management, inventory control, SEO tools, and marketing capabilities, to help you drive more traffic to your ecommerce store.
With Klaviyo’s BigCommerce integration, you can:
- Create and deliver marketing emails, text messages, and on-site sign-up forms, including pop-ups and fly-outs.
- Segment by products purchased in specific timeframes using historical data, website browsing behavior, order value, and more.
- Use AI and machine learning to benchmark your performance, generate subject lines and texts, and personalize using predictive analytics.
Mitch McKay, former manager of marketing technology partnerships at BigCommerce, praises Klaviyo’s BigCommerce integration for its wealth of customer data: “It’s truly improving customer shopping experiences, and creating a relationship between that customer and your brand.”
Agentforce Commerce
Agentforce Commerce (formerly Salesforce Commerce Cloud) connects your entire business on one unified platform, from ecommerce and POS to order management. It's got AI baked in to proactively help your team with merchandising and guide customers through their buying journey.
Klaviyo's Agentforce Commerce integration uses a cartridge, or a pixel, that tracks website behavior in real time. The set-up is streamlined with out-of-the-box event tracking, pre-built flows for abandonment and order confirmation, and cart rebuild links that send shoppers directly back to their cart. You can also add consent checkboxes during check-out to grow your email and text message lists.
Adobe Commerce
Adobe Commerce (formerly Magento 2) is flexible and customizable, allowing you to create custom themes and templates. It includes out-of-the-box features like inventory management, integrated check-out, and more, and also offers a page builder so you can create the personalized storefront experiences you want.
Integrate Adobe Commerce with Klaviyo to:
- Grow your subscriber lists with web forms that don’t need code.
- Get a unified view of your customers’ actions in your Adobe Commerce store, including placed, refunded, canceled, and fulfilled orders.
- Segment products purchased in specific timeframes using historical data like website browsing behavior, order value, and an unlimited number of custom attributes.
- Use built-in flows for ecommerce use cases across the lifecycle that can be triggered by event-level data.
Justin Ragsdale, VP of strategy at full-service digital agency IM Digital, calls Adobe Commerce the “Rolls-Royce of ecommerce platforms.” Most of the agency’s Klaviyo clients, whether B2C or B2B, use Adobe Commerce as their ecommerce platform.
“They’re using Klaviyo for everything because it’s so incredibly easy to use,” Ragsdale says. “With everything else that’s going on, Klaviyo requires a relatively small investment of time and money to get powerful automations up and running. Klaviyo’s Adobe Commerce integration affords you the opportunity to monetize all of that data that you’ve been gathering this whole time.”
Shopware 6
Shopware 6 is a European open-source ecommerce platform that gives brands full control over their code. It's a favorite for companies selling everywhere (their website, marketplaces, social media) who need customization that cookie-cutter platforms can't provide.

Klaviyo’s Shopware 6 integration syncs data in real time and backfills historical records via webhooks and APIs. Customer actions like registrations, orders, and refunds are pushed to Klaviyo as they happen, so you can send relevant and timely messages when customers need or want them most.

JMango360
According to a recent Bryj survey, 64% of respondents prefer to use a brand’s mobile app rather than visiting its website through a mobile browser. Mobile apps are an easy (and preferred) way for customers to connect and transact with your ecommerce business.
JMango360 turns your online store into an iOS and Android app, with features like push notifications and mobile-optimized check-out. It uses push notifications, in-app experiences, and loyalty features to increase customer lifetime value without relying on third-party cookies or rented channels.
You can use Klaviyo’s JMango360 integration to engage with customers on mobile and drive more revenue by:

Spree
Spree is an open-source ecommerce framework that gives developers complete control over store functionality and is highly customizable for unique business needs.
Klaviyo’s Spree integration tracks everything: product view, product added to or removed from cart, coupon entered or removed, newsletter unsubscribes, order completed, order cancelled, and so much more.
Each of these events populates in Klaviyo, where you can view and track each customer’s activity and properties. Use this information to personalize marketing messages based on what each person actually bought and did on your site.
Vanik
Vanik helps Shopify merchants manage wholesale operations more efficiently, using wholesale data to anticipate and automate ordering. According to the platform’s website, “We didn’t think that it was fair that brands selling DTC have software solutions to help automate the ordering process, but brands selling wholesale don’t.”
With Vanik, retailers can place orders in as little as two clicks, right from an email, and sellers can send predictive reorder reminders.
Klaviyo’s Vanik integration empowers you to better manage your wholesale relationships, with:
- Automated wholesale reorder reminders based on retailer sales information, so you're reaching out when they actually need to restock

Fourthwall
According to data from Clutch, 87% of Gen Z, 78% of millennials, and 77% of Gen X are open to buying products based on influencer recommendations.
Fourthwall is an ecommerce platform specifically for content creators—like YouTubers, Twitch streamers, and podcasters—who want to sell merch and digital products to their communities.
Klaviyo's Fourthwall integration syncs your supporters' order contact information, like email addresses and phone numbers. You can segment fans by what they've purchased and send targeted marketing messages for new product drops, limited releases, and exclusive offers.
Shift4Shop
Shift4Shop includes built-in features that other ecommerce platforms typically require third-party apps to handle, including marketing, inventory management, SEO, and customer tools. It also offers a large selection of website themes, which you can customize with built-in tools or edit the code directly.
Klaviyo’s Shift4Shop integration syncs customer data for targeting and tracks live site activity like product views and navigation patterns. You can use that data to personalize email and text messaging based on what people actually do on your site.
OpenCart
OpenCart is a free, open-source ecommerce platform that gives you complete control over your store's design and functionality. Because it’s open-source, you only pay for hosting, the extensions you choose, and development work.

commercetools
commercetools lets brands easily customize code to fit their business needs and create unique shopping experiences. With their set-up, you can create unique customer experiences—custom storefronts, app-based commerce, voice shopping, or any other interface—while the commercetools platform manages the logic behind the scenes.

- Manage complex product data, customer history, and past orders through an AI-ready interface for easy set-up.
- Segment customers to target groups with hyper-personalized pricing and promotions.
- Track system changes and user actions with a centralized audit log.
CommentSold
The shopping world is becoming more and more visual: a study from Kantar and Google found that 45% of respondents prefer watching videos when doing research that helps them make a decision.
CommentSold capitalizes on this trend by enabling live video commerce and social selling. Sellers broadcast live shopping shows on Facebook and Instagram, and customers can purchase by commenting on the video. What was once a simple way to engage on social is now a direct line to completing a transaction.
This format works particularly well with beauty, fashion, and lifestyle products, where showing people using products makes other people want them. And live selling creates community, where regular viewers turn into loyal customers who tune in for each “show.”
When you integrate Klaviyo with CommentSold, you can meet shoppers where they prefer to buy and collect customer data from live sales and social commerce transactions. Use this data to segment customers by which live shows they've purchased from and send follow-up messaging announcing new shows and exclusive offers.
