E-commerce 101: an essential guide to the sector

Choosing from the multitude of e-commerce options for your business can seem like an intimidating task. From plugins to online stores, finding the right choice for your particular needs can be a challenge.

The great thing about having lots of options is that you can be confident in eventually deciding on the perfect solution. To help you get started, we’ve put together an ‘e-commerce 101.’ This blog post will explain everything you need to know about e-commerce, as well as highlighting the best e-commerce platforms and letting you know how to get started.

What is e-commerce?

Breaking down what e-commerce–or electronic commerce–actually is can help to unwrap some of the questions around choosing the right platform and site. According to the Cambridge Dictionary, e-commerce can be defined as “the buying and selling of goods and services over the internet.”

Simply put, anytime a transaction takes place over the internet, e-commerce is happening. e-commerce is also sometimes referred to as e-business or internet commerce and it can include many different types of transactions, including the transfer of data and goods.

Why is e-commerce so important?

The importance of e-commerce is easy to understand when you think about the world of today. The internet has become the focal point or at least the location of a huge portion of our lives. From entertainment and dating to food deliveries to banking, our lives have gone online.

That’s why it makes sense for business owners to look into how their product or offerings can be translated online. As of 2020, around 59% of the world’s entire population were online–that’s a huge 4.45 billion people. You should aim to target and showcase your services to where potential customers are, and, as these numbers prove, they are highly likely to be online. According to Nasdaq, it’s thought that by 2040, 95% of shopping in the UK will be facilitated by e-commerce.

What to consider when choosing an e-commerce platform

In the next section of this blog post, we’ll break down different e-commerce websites for you to consider and select from. But first, let’s take a look at the features of an e-commerce site and the things you should think about to guide your choice.

Site design

The style and themes that an e-commerce platform can offer are important to consider when choosing which site or plugin is for you. Different options allow you different levels of customisation when it comes to things like logos, colours, product catalogues and individual designs.

If you’re just about to begin your e-commerce journey a more simple interface would be ideal for you. Having limited design choices might sound negative, but it’ll actually allow you to focus on the important tasks that come with adapting your products or services to suit being sold online.

On the other hand, if you’ve already started selling online or you have a bit more experience in web design, then a more complex plugin integration could be a great option as it’ll allow you to tailor the interface to match your brand and style.


Especially if you’re just starting out in the e-commerce world with your first online store, it’s crucial that you choose an e-commerce option that gives you good support should you have questions.

Whether that means a technical support team to help if things go wrong, or a dedicated key account manager to keep an eye on how your business is doing and offer advice when it’s needed, check the level of support you’ll receive before selecting an e-commerce site.

Mobile suitability

With your audience viewing your products and looking to make purchases on the small screens of their mobile devices, it’s important to consider which e-commerce site will give them the best experience.

Look into how mobile-friendly the e-comm platform will make your online store. Does the design work? Are the pages easy to follow? Is it simple to select products, order and pay? All of these questions need to be answered when choosing your e-comm solution.


When you’re asking your customers to trust your website and to hand over their financial details to make orders and payments, you need to make sure you protect these details safely and securely.

You need to make sure that how you choose to take payments is fully compliant with legal regulations and that how you store data is in line with GDPR requirements.

Where to start

As previously mentioned, there are a lot of options available for business owners who want to move into the e-commerce space. To begin with let’s take a look at SumUp’s own solution…

Online Store

A great place to start with e-commerce is with the SumUp Online Store. This option is fantastic, especially for small business owners and people who are already using social media to promote and advertise their products.

With the Online Store you can start selling your products online in a matter of minutes with your SumUp profile. The plan allows you to easily create an online store where you can add your products, social media links, and shipping details. It can be enabled on the SumUp app to enable you start transacting online quickly and securely.

Depending on the nature of your business, you might want to look into alternative options. For example, you might have already launched an online store but want to explore payment opportunities, or maybe you fancy yourself as a coder, so building a website from scratch might be more up your street.

With SumUp’s integration products, partners can use our e-comm API to accept customer card payments from within their own platform, creating a rounded and connected omnichannel experience. Some of our e-comm partners that you should consider are:


If you’ve already set up an online store using the WordPress CRM system, then taking advantage of SumUp’s plugin with WooCommerce is ideal for you. WooCommerce is a WordPress e-commerce plugin available to download. SumUp’s Payment Gateway for WooCommerce will give your website the option to accept payments in your online store. The plugin is a lightweight option that enables quick and easy integration with limited technical expertise.

This option enables customisation and provides your customers the convenience of securely buying products from your website without being redirected to other pages. Transactions are processed through the SumUp payment platform, allowing you to track your transaction history through the SumUp dashboard.


Wix is a great, all-in-one e-commerce option. Its simplicity and easy to use drag and drop style interface makes it the perfect option for beginners and people who don’t have any coding experience. While WooCommerce requires some prior developer knowledge in order to make significant modifications, Wix has fixed templates and a dedicated team to introduce new features and fixes.

Wix does have a few more restrictions when it comes to customisation in comparison to WooCommerce, but it’s been designed and set up in a specific way which makes it perfect for non-developers to use. You can find templates, plugins (including the SumUp integration), security and technology all housed within one system, making setting up a professional e-commerce website simple and easy.


If you’ve got some experience with web development, another great option is the OpenSource e-commerce solution, PrestaShop. Given the nature of the OpenSource software, PrestaShop allows users to make completely customisable e-comm stores, with no restrictions or limits. There are also training materials and a support team on hand to help with any technicalities.

PrestaShop is integrated with SumUp as a payment provider for transactions on your site, meaning you can trust that your e-comm finances are 100% secure and reliable. The interface is simple and easy-to-navigate so your customers can select and then pay for their items quickly and smoothly.
