Just a few years ago, it would have cost you a fortune to make an eCommerce website. Luckily with the rise of eCommerce, you can now build a beautiful and robust online store in a wink. Some eCommerce platforms are bundled with content management systems while others are stand-alone platforms that include only what is needed to sell.

Whether you’re a startup or looking for a solution to expand, an eCommerce platform has a huge impact on the stability and profitability of your business. This article compares the 4 most popular and best eCommerce platforms in 2021 to help retailers choose the most suitable solution for your online business.

What is an eCommerce platform?

An eCommerce platform is a solution for online businesses to handle the process of selling and buying online on your website. This includes sales, marketing, and operations with 3 basics features:

  • Search: to find desired products
  • Shopping cart: to manage orders
  • Checkout: to complete the purchase

Since online customers can’t touch and feel products, the best eCommerce platform will make it easy to:

  • Return the search results related to your website to customers
  • Present products in clear and attractive ways
  • Assist customers in finding products more quickly

It should be able to grab your customers’ attention from a wide selection of vendors on the market and deliver a great customer experience.

Types of eCommerce platform

Based on the type of deployments, there are 3 main eCommerce platform options:

  • SaaS (software-as-a-service): an on-demand platform that is centrally hosted and licensed on a subscription basis
  • Open source: a platform whose license includes the open source code for further customization
  • Headless commerce: an architecture in which the interface of the user end (head) is separated from the functionality of the commercial end. Therefore, you can edit and update it without interfering with the frontend.

Key things to consider with an eCommerce platform

Determining the criteria before choosing the best eCommerce platform for your business is very important. If you choose wrongly, the conversion will cost you a lot of effort, time, and money, and service disruption for your customers. Before committing to a certain platform, you should do some research in advance based on the following 7 factors:

1. Pricing vs. your budget

Cheap options often cost you extra for advanced features and functionality. However, paying more doesn’t always lead to a better experience. Even with the best eCommerce platform packages, you still need to understand what you’re really getting to see if they’re cost-effective. Merchants should figure out the desired budget for:

  • Licensing
  • Monthly hosting
  • Maintenance
  • Programming and functionality
  • Web design
  • Security

If you choose independent web hosting, you will need extra fees for services from other providers. But if you choose an all-in-one host, you’ll often have the option of a premium plan that includes all the features. Whichever option you choose, compare the total cost with your budget.

2. Payment processing

Having a variety of payment options increases the likelihood that customers complete their purchase and reduces the hassle of the checkout process. If your website is international, the best eCommerce platform should accept or be able to integrate with local payment gateways in addition to popular options like Stripe, PayPal, and Apple Pay.

3. Analytics

To know if your website is performing well, you should choose the best online platform with built-in analytics. That helps you easily track important eCommerce metrics to your business such as churn rate, sales conversion rate, average order value, and customer lifetime value. At the very least, the platform you choose should be able to integrate with third-party eCommerce analytics.

4. SEO-friendly

Not every customer knows about the existence of your eCommerce store. To increase discovery, your website needs to appear in search results not only for your brand name but also keywords related to your products and services. To achieve this, you should find the most SEO-friendly eCommerce platform to:

  • Add content or blog to drive organic traffic
  • Have the ability to customize your domain name
  • Allow and publish visitors reviews

5. Mobile-friendly

Customers are increasingly using mobile devices to make purchases. It’s important to create a mobile-friendly eCommerce store so that customers can easily browse and purchase from their mobile devices. You can read more in our article Understanding mobile commerce: What, why, and how.

6. Integrations and apps

Integration and application capabilities are important factors when looking for the best eCommerce platform. They help to extend the functionality of the eCommerce platform at any time as the business expands in the future. Additionally, you’ll want to make sure your eCommerce platform works with the solutions you already use, like inventory management, email marketing, and accounting tools.

7. Support

You’ll sometimes still need technical support even with the easiest-to-use eCommerce platform. Here we consider the availability of support options and the quick resolution time. In addition to self-help channels like community forum or knowledge base, your eCommerce provider should have many options like email, phone, and live support.
