Do you currently process card payments?
Online payment systems include the elements required to accept online payments for goods and services. An online payment system will usually be made up of a number of 3 main components:
These individual elements can come separately or packaged as a single service so you may not realise you are receiving all three from one company offering an online payment system.
At a very high level, a payment gateway is a form of software that securely transfers information between the card network and the payment processor.
Businesses will also need a merchant bank account that allows them to accept credit and debit card payments but this is normally provided by the payment processor.
The right online payment solution for your business will depend on its size, card transaction volume, and a number of other factors.
Some specialist providers allow businesses to host their own checkout by using an API (Application Programming Interface) solution, but most SMEs will be better served by an out-of-the-box hosted solution.
Many lists of payment systems can be regarded as a list of options to accept payments online that can be combined into a single online payment system.
For example, eCommerce platforms such as WooCommerce and Shopify allow you to choose from (and even combine) multiple online payment methods including PayPal, Klarna, and Amazon Pay while using a merchant account such as WorldPay, Global Payments, or First Data to process and bank the revenue you generate.
Before deciding which route is best for your business, it’s important to understand the difference between hosted and self-hosted online payment systems.
Hosted online payment systems are easy to set up and manage, since the checkouts and infrastructure are already designed. This means that businesses can use hosted solutions without the need for extensive coding experience.
These solutions are offered by eCommerce providers such as Shopify and BigCommerce, along with numerous payment processors such as Stripe.
Self-hosted online payment systems may offer more extensive customisation options, but this comes with added complexity.
Businesses will need to have some coding capabilities to manage a solution using an API (Application Programming Interface), and this option is arguably more suitable for those with a higher turnover and the need for flexibility.
Providers of self-hosted online payment systems include Ayden, Braintree, Stripe, and Checkout.com.
Although you may be left with less control over your payment processing by using these integrated eCommerce payments, they do simplify the entire process. This is why many small businesses choose to work with an eCommerce platform that can provide them with the functionality of an online payment system without the need to create their own infrastructure.
Below are some of the best specialist online payment system providers which include:
Stripe is a major international payments platform that has become popular amongst start-ups and growing businesses of all sizes. While it can be complex to set up using its API, Stripe comes with extensive customisation options and can be customised to meet your business needs.
Transaction fees are transparent and lower than many of the other providers that publish fees (although still higher than most businesses can get by integrating with their own payment processor / merchant account which we can help with). There are no set-up fees or monthly costs. Businesses should, however, be aware that Stripe applies a reasonably expensive rate to non-European card transactions.

Below are some of the most popular online payment systems with an international focus:
2Checkout is one of the biggest names in online payment processing, and has a strong track record for providing stellar support for international payments. While the company’s rates may be higher than some providers, they do offer a transparent service that’s easy to set up and use.
As one of the original companies to offer online payment processing, 2Checkout provide a user-friendly service – but it’s worth keeping in mind that the market has expanded significantly since they first started, and other options are available.

| Best Suited To | SMEs that require international payment support and are not concerned about spending more on transaction fees. |
Authorize.net is one of the oldest names in online payments and still one of the favourite choices for online retailers around the world. Its key selling point is its robust international payments functionality and this makes it another option for retailers selling to multiple countries.

Which online payment system is right for your business will depend on a variety of factors including costs, transaction volume, and the products and customers that you deal with.
An integrated solution will suit the vast majority of SMEs, but businesses that require further customisation options may benefit from a self-hosted online payment system developed using an API.
It is often best to avoid online payment systems offered by merchant acquirers like Worldpay, Opayo etc as they don’t have the tech skills to produce the quality of online payment systems provided by the specialists.
Their merchant accounts for these online payment providers may well be worth considering due to their fees but we’d advise avoiding using their default online card payment systems and just integrate with one of the systems above or another payment gateway.
Taking online payments in the UK doesn’t have to be difficult or expensive.
