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


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:

  • Ultra-secure payments
  • 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 £49.99 a month all-in (transaction and authorisation fees included)

2. PayPal: Best for fast transfers


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 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?

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

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,, 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.
