What is an ecommerce shopping cart?

An ecommerce shopping cart is a type of software that allows customers to purchase items from your shop or store a list of the items they wish to purchase in the future.

There are two main types of ecommerce shopping carts:

  1. Hosted/self-hosted shopping cart. This type of ecommerce shopping cart is provided by a third party. Typically, it’s easy to set up and integrate with other business tools and platforms. Hosted shopping carts are great options for new businesses and businesses with limited technical resources.
  2. Licensed shopping cart. A licensed ecommerce shopping cart is completely custom. While you have more control over the functionality and design, it requires more technical resources for implementation and maintenance. Typically, licensed shopping carts are good for enterprise businesses or merchants with complex tech stacks.

Why is choosing the right ecommerce shopping cart important?

Picking the best software will make the shopping cart experience seamless and customers more likely to buy. This is the last place a customer visits before they make a purchase. You don’t want to lose them here to shopping cart abandonment.

The average cart abandonment rate is almost 70%. As a result, ecommerce stores lose as much as $18 billion in sales revenue each year to abandoned shopping carts. When you choose the right ecommerce shopping cart for your online store, you can salvage many of these lost sales and boost your conversion rate.

Plus, you actually need an ecommerce shopping cart to convert online sales, accept payments, and process transactions. Without it, online shoppers would have no way of choosing items and paying for them. Your ecommerce site would be simply a website without ecommerce functionality.

Modern online shopping carts also store important data you can use for other purposes, including marketing, forecasting, and pricing strategies.

How to choose the right ecommerce shopping cart for your website

Consider the following factors when researching options for your online store’s shopping cart:


All merchants need to consider budget when selecting an online shopping cart. And this goes beyond simply looking for the best price. Sometimes, the cheapest option isn’t the best option.

Typically, self-hosted ecommerce shopping carts are more affordable, but they’re not always the best. They have more limited functionality when compared to a full-featured option like Shopify, and you also need to invest in technical resources to build and maintain it.

When looking at pricing, consider the following:

  • Monthly fees
  • Payment processing fees
  • Minimum transaction volume requirements
  • Transfer fees
  • Cancellation or early termination fees


You’ll want to look for an online shopping cart that offers not only integrations with your existing ecommerce platform and tech stack but additional options as well. Chances are, your online business will grow over time—and you need business tools and ecommerce solutions that can adapt and grow with you.

Accepted payment types

It’s important to select an online shopping cart that works with a variety of payment methods, including credit and debit card, mobile wallets, PayPal, and buy now,, pay later services, among others. About 7% of people abandoned their shopping cart because aa merchant didn’t provide enough payment method options.

Additional payment options can boost not only conversions but also average order value (AOV). One in four merchants using Shop Pay Installments double AOV when allowing customers to spread the cost over monthly payments, for example. Flexible payment options increase consumer spending power.

You want to be able to adjust the look and feel of your online shopping cart to both match your branding and optimize the user experience for the most sales. An estimated $260 billion worth of lost orders are recoverable solely through a better checkout flow and design. With some improvements to the checkout design, a large ecommerce business has the potential to drive a 35.26% increase in conversion rate.

This might involve reducing the number of steps in your checkout flow to reduce friction. The average US checkout flow contains 23 form elements by default—that’s a lot of data to input. With an ecommerce shopping cart like Shop Pay’s 1-click checkout, you can simplify the flow and make it easier for shoppers to convert.

Shipping options

High shipping costs are a leading cause of cart abandonment. Find an ecommerce shopping cart that allows you to customize shipping options and even letlet customers select how they want their orders shipped.

More importantly, ensure the shopping cart experience makes these costs transparent. As many as 17% of shoppers abandon their cart because they can’t calculate the total order cost upfront. It’s your job to do this for them.

Weebly is a basic online store builder with affordable pricing options. It’s owned by Square, so it integrates seamlessly with other Square-owned platforms. If you don’t have the technical know-how or resources, Weebly is a friendly entry-level online shopping cart to use.


However, it has its limitations. Weebly is more restricted than other online shopping carts when it comes to functionality and customization. Because it’s so affordable, it also scales back on features.

However, merchants can post store return and shipping policies, allow customers to add notes in a dedicated field in the checkout flow, and grow your email marketing list.

The Weebly online shopping cart at a glance:

  • Pricing: Free basic account; Personal: $9/month ($6/month billed annually); Professional: $16/month ($12/month billed annually); Performance: $29/month, ($26/month billed annually).
  • Payment types: Credit and debit card; Square; Stripe; PayPal; Apple Pay; Android Pay.
  • International payments: Depends on payment gateway.
  • Ecommerce integrations: n/a (Weebly is an ecommerce platform) 
  • Other business tool integrations: Square suite of tools and integrations.
  • Shipping options: Automatically calculate and display shipping costs based on weight, number of products, location, and carrier.
  • Customization: User-friendly drag-and-drop editing; add field for customer notes; automatic sales tax calculator; security badges; abandoned cart.


Ecwid is a bit different from other options on this list because while it offers a dedicated online store builder, its main purpose is to turn a portfolio of websites into ecommerce sites. Essentially you add Ecwid to your existing websites, landing pages, or digital entities and that allows users to add products to a shopping cart and then buy them.


Like Weebly, Ecwid is user-friendly, and you don’t need technical coding skills to start selling online. Once you add it to your various digital properties, Ecwid syncs and centralizes all your order data to avoid discrepancies.

You can certainly use Ecwid’s online store builder, but it lacks the depth of features growing brands need.

Ecwid online shopping cart at a glance:

  • Pricing: Free to build and launch your store with up to 10 products; monthly business plans start at $15 ( $12.50/month if paid annually); no additional transaction fees.
