Take Payments Online with WooCommerce and SumUp: A Guide for Small Businesses

If you’re a small business owner looking to take your products or services online, WooCommerce and SumUp make an excellent pairing. Together, they offer a streamlined, secure, and affordable way to accept card payments directly on your WordPress website — perfect for businesses just starting out or looking to expand their online presence.

What is WooCommerce?

WooCommerce is a free, open-source eCommerce plugin for WordPress that transforms your website into a fully functional online store. It’s flexible, scalable, and customisable — whether you’re selling handmade crafts or offering professional services. It also supports thousands of plugins and themes, making it easy to extend its functionality as your business grows.

You can learn more about WooCommerce on their official website.

Why Use SumUp with WooCommerce?

SumUp is a well-known payment solution provider that enables businesses to accept card payments both in person and online. By using the SumUp Payment Gateway for WooCommerce, you can offer a secure checkout experience that’s fully integrated into your website — no need to send your customers to an external site to complete payment.

This integration allows you to accept all major debit and credit cards, including Visa, Mastercard, American Express, Diners, Discover, and more. You can also accept digital wallets like Apple Pay and Google Pay, depending on your setup.

Benefits for Small Businesses

One of the best things about using SumUp with WooCommerce is the low barrier to entry. There are no monthly fees, no lengthy contracts, and no setup costs — just a small transaction fee when a customer makes a purchase. This makes it ideal for startups and small businesses that want to keep costs predictable.

Payments are processed securely and funds are typically deposited into your bank account within 1–3 business days. You can view all your transactions — both online and in-store — via the SumUp Dashboard, which helps keep everything in one place for easy management.

How to Set It Up

To get started, log in to your WordPress site and go to Plugins → Add New. Search for “SumUp Payment Gateway for WooCommerce”, then install and activate the plugin.

Once installed, connect your SumUp account using the secure OAuth setup. You’ll be redirected to SumUp’s login page where you can authorise the connection, and the plugin will take care of the rest.

After connecting your account, head to the plugin settings in WooCommerce to enable the payment method, customise how it appears to your customers at checkout, and fine-tune options like currency and logging.

Make sure your site is compliant with eCommerce best practices. This includes having a clear refund policy, contact information, terms and conditions, and product descriptions with visible pricing. WooCommerce makes managing all this straightforward — and if you need a hand, that’s what we’re here for.

What to Watch Out For

While the SumUp plugin is relatively easy to use, there are a few limitations to be aware of. It currently only handles payment processing — it doesn’t sync your WooCommerce product list or customer data with SumUp’s in-person point-of-sale system. Also, depending on your hosting environment, some users may encounter compatibility issues that require a dedicated IP address or updated PHP settings.

That said, for most small business owners using standard hosting setups (like the ones we provide here at O’Brien Media), it works brilliantly out of the box.

Let’s Get You Selling Online

Combining WooCommerce and SumUp gives small businesses the tools they need to start selling online quickly and affordably — all while maintaining control over the customer journey. Whether you’re launching a new business or adding an online shop to your existing setup, it’s a smart move.
