It’s now easier and more affordable than ever to set up an ecommerce website and start taking payments online.
You can create a website and reach millions of customers, who can then make a purchase at the click of a button.
But what exactly do you need to take payments online? How do you set up online payment systems? And what are the online credit card processing fees?
There’s a dizzying variety of ways you could accept online payments, due to the countless combinations of platforms and processors you could use. To make things easier, we’ve decided to focus on what we think are the easiest and most affordable options for small businesses.
How to take payments on a website: payment processors
In order to take payments on a website, you need to either be registered with a payment gateway and a merchant account, or to be registered with an all-in-one online payment processing solution like PayPal, Stripe, or Square.
As a small business, for ease, we’d recommend using an online payment gateway. This avoids you having to go through the application and approval processes, and negotiating fees, with separate payment gateway and merchant account providers.
To sign up with a payment processor, just visit their website, create an account, provide some basic info about your business, and (pending approval) you’re ready to go. Unlike the payment gateway and merchant account option, you generally won’t be tied into a long-term contract with a or be charged monthly fees.
Take payments online using a website builder
Taking payments on Squarespace, Wix, Shopify or any other website builder couldn’t be easier. Website builders generally have payment processing and checkout functionality built in, and integrate with numerous payment gateways. All you have to do is:
- Step 1 – sign up for an ecommerce plan with your website builder of choice
- Step 2 – create your online store using a template with product listings and a checkout page
- Step 3 – enter ‘settings’ and connect a compatible payment processor (e.g. Stripe, PayPal, Square)
- Step 4 – start taking payments
Alternatively, Shopify has its own fully integrated payment gateway, Shopify Payments, which eliminates transaction fees from third-party providers.
Commerce plans for the likes of Wix (£13-£22 per month) and Squarespace (£12-£79 per month) are much cheaper than Shopify (£19-£1,800 per month), though the latter does distinguish itself with more advanced sales features.
Taking payments on a WordPress website
The easiest way to take payments online if you set up your website using a content management system (CMS) like WordPress is to use one of WP’s own e-commerce plugins, such as WooCommerce.
Like Shopify, the WooCommerce payment gateway’s fully integrated into the CMS, and allows you to accept payments in more than 135 currencies. You can download and install WooCommerce Payments for free and at no monthly cost.
Using a CMS to take payments
Using a CMS like Adobe Commerce or OpenCart is another popular way to build an ecommerce site.
These open source platforms are excellent if you want the freedom to create a bespoke online store, but they do require serious time, energy and coding skills, and you (or a developer) will have to manually create the checkout and payments functionality.
Online credit card processing fees
Fees vary between payment processors and website builders, so it’s worth shopping around for the most competitive rates. To help you understand how your fees might break down, we’ll look at a variety of examples.
GoCardless
GoCardless provides a cost-effective way to accept one-off or recurring payments online, via direct debit. Automating the payment collection process avoids the high fees, complexity and failure rates of cards, and gives you more control than a standing order.
GoCardless currently supports collections from more than 30+ countries at the real market exchange rate. Features like Success+ automatically retry failed payments—recovering 70% on average—while Protect+ monitors transactions to protect you and your customers from fraud.
GoCardless fees:
- Domestic UK – 1% + 20p (capped at £4)

Squarespace and third party payment processor
As a Squarespace user, you can either use the platform’s native payments solution or connect to a third-party processor like Stripe or PayPal (for an additional fee). Squarespace doesn’t charge transaction fees for the sale of physical, download, or service products on most of its premium plans, but Basic plan customers pay 2%, and Business plan users pay 3%.
However, you are still charged payment processing fees, which are currently:
- Domestic personal debit or credit cards – 2% + £0.25
- Domestic business/corporate debit or credit cards – 3% + £0.25
- International personal debit or credit cards – 3% + £0.25
- International business/corporate debit or credit cards – 4% + £0.25
Shopify Payments
Shopify is a full-featured ecommerce platform designed to help small businesses get the most out of selling online. It allows you to accept local and global payment methods, and to promote and sell across multiple channels, including Instagram, TikTok and Google. You can also accept crypto, Klarna and other alternative payment types.
You can use third-party payment providers with Shopify for an additional fee. However, if you use Shopify Payments, you avoid those fees and pay a single processing fee per transaction, which varies by plan. Prices start from £5 per month to sell through social media and messaging apps.
Shopify online card rates by plan:
