This article will review each payment gateway in detail – (you can click on the name of each payment gateway provider to jump to the relevant section).


In order to assess the best payment gateways, it's worth remembering what they're designed to do. A payment gateway is an online payment system which accepts customers’ card details, transmits the charges and helps you manage the payments that come in through your website. Managed by an e-commerce service provider, a payment gateway will authorise credit card or direct payments online.

Functions of a payment gateway include:

– Encryption (of data)
– Authorisation (of payment)
– Filling and processing (of the order, via the merchant website)
– Delivery address verification

1. Worldpay: The UK’s number one payment gateway

worldpay

Worldpay is the UK’s most popular payment processing company – currently processing around half of all payments taking place in the UK – and has some of the most flexible plans for small businesses.


Worldpay pros and cons:

  • Flexible price plans
  • All major cards accepted

Secure – Worldpay takes your online security very seriously, and comprehensive fraud screening protects you and your customers

Fixed monthly From £19.95 a fixed monthly payment, plus 2.75% (credit cards) & 0.75% (debit cards).

2. PayPal: Best for fast transfers

paypal

You may remember PayPal from such hit ecommerce websites as eBay, where it made checking out more pain-free than we ever thought possible. But PayPal is just as user-friendly for businesses as it is for customers.

Today, its payment gateway – named Payflow Gateway – is widely trusted, with over 220 million users worldwide. Its online payment system is also nice and budget-friendly for businesses with ambitious sales – though less so for those with smaller targets.


PayPal’s Payflow Gateway pros and cons:

  • It's easy to pay with PayPal
  • Simple setup
  • A reliable payments solution
  • Robust fraud protection
  • Mobile-optimised site
  • International cards accepted
  • High fees for low sales
  • The free version comes across as basic

What’s PayPal’s Payflow Gateway like?

Easy to use – An easy to use and flexible payments service that lets you tailor your online checkout to create the best shopping experience for your customers, including tweaking the layout to your brand’s desire

International – Sell products abroad and get paid from all over the world

Safe – An extra secure online payment solution with encryption and strict PCI compliance

Flexible – Supports all the main credit cards (including Visa, Mastercard, Discover, and even American Express)

A team player – PayPal Payments Pro integrates well with all main e-commerce platforms

Super speedy – The question on everyone’s lips – when do I get my money? – is where PayPal really is head and shoulders above the rest. Once you make a sale, you’ll be able to see the funds in your PayPal account almost instantly. By contrast, with many other payment processing providers you can expect a settlement time of two to three days


PayPal fees: What'll it cost me?

Fee type Cost
PayPal’s transaction fees 1.9% plus 20p per transaction (for sales of up to £55,000 a month), 3.4%plus 20p per transaction (for sales under £1,500 a month)
PayPal’s monthly fees Free via Web Payments Standard or Express Checkout, £20 a month via Web Payments Pro


Is PayPal for me?

PayPal’s online payments system is flexible and intuitive enough to work wonders for small businesses and start-ups, even first-timers.

And don’t worry, your customers don’t need a PayPal account to use PayPal Payments Pro – software you can integrate with Payflow Gateway to create a customisable online payment solution.

Payflow Gateway is especially perfect for international businesses (or any with their eyes set globally), as it accepts a whopping 26 currencies in over 200 markets.

3. Stripe: The best full service payment provider

stripe

Stripe is one of the most popular full service payment providers – that means it includes your payment gateway and your merchant account – and is the go-to for creating your own customised payment system.


Stripe pros and cons:

  • Clear pricing with no hidden fees
  • Intuitive platform
  • Recurrent payment option
  • Live sales reporting
  • Great fees for EU cards
  • Some tech know-how needed
  • High fees for non-EU cards
  • Up to seven-day settlement delay

What's the Stripe Online Payment System like?

Extra speedy – Digital wallets, including Apple Pay and Google Pay, give customers an extra speedy way of paying with Stripe, and you can save time with automated dispute handling too

Powerful – Stripe supports handy features like mobile payments, subscription services and one-click checkouts

Robust – Billions of pounds pass through this platform each year, in hundreds of currencies

Safe – Stripe offers secure payment processing with added authentication to protect you from fraud or costly chargebacks

User-friendly – Stripe’s handy dashboard that enables you to gain a 360 view of your payments

Clear – Even the pricing structure is as flexible as the software: you can choose to pay for the stuff you really want – and cut out any fluff

Nearly complete – You’ll just need your own website and shopping cart to get selling online


Stripe fees: What'll it cost me?

Payment method Fee per transaction
EU cards 1.4% plus 20p
Non-EU cards 2.9% plus 20p
SEPA Direct Debit Free via Web Payments Standard or Express Checkout, otherwise 1% plus 20p (minimum £5)


Is Stripe for me?

Stripe is a great online payments solution for small businesses in a range of industries – it’s already trusted by brands as diverse as Deliveroo, ASOS, Made.com, Pinterest, and Under Armour, to name just a few.

But the ultra-clear prices also make Stripe the ideal payment gateway, even for low-volume businesses who simply want to keep an eye on cashflow and avoid nasty surprises.

Plus, if you run a subscription service (like a magazine), you’ll like Stripe’s recurrent payment features.

But beware – while this platform has plenty of helpful guides, it was really designed for techie business owners who are after a suite of tools to help them build an online payment system themselves; so if you’re a total beginner it may not be for you.

Tips for choosing the right payment gateway for your business

When it comes to payment gateways, there’s a lot to consider and it can be hard to streamline your approach. To help with this, we’ve created a handy list of what to look out for when it comes to choosing the perfect payment gateway for your startup.

  • Security
    This is important for both you and your customers. Keep your eye out for PCI-compliance (crucial for accepting credit card payments)
  • Data portability
    Who owns your customer’s data if you choose to leave your gateway?Make sure you know how to download and move the data you need to sustain your merchant services without breaking GDPR
  • Hosted/integrated gatewayswhat’s the difference?

    A hosted gateway will redirect your customers to the payment processor’s platform (they’re easy to set up and ideal for new businesses)

    An integrated gateway connects to your eCommerce website via the gateway’s provided API (meaning that your customers will never leave your site to input payment information)

  • The customer journey
    Customers will be looking for convenience, clarity and security – things to avoid include too many steps and too many details required from the customer, as this will take too much time and increase the chances of the customer abandoning the purchase
  • Cards accepted
    It’s standard for payment gateways to accept all major credit and debit cards, but double check (and if the gateway accepts American Express, that’s a bonus – be sure to check the processing fees though!)
  • Mobile optimisation
    Phones are the future of e-commerce, and if your payment gateway isn’t geared up for smartphones, then you’re probably missing out on some serious sales opportunities
  • Fees
    Each payment gateway charges a different amount for credit, debit and overseas transactions – so be sure to swat up on what the charges are and make sure you’re not going over budget
  • Customer support
    If your gateway goes down, you won’t be able to accept payment for your products (which is bad news for business) so it’s important that your payment gateway provider has an efficient customer support network that can help out with any problems, any time
