The leading payment gateways
When choosing a payment gateway, you’ll need to evaluate how many transactions you’ll be processing. PayPal and Stripe are appropriate for low-volume sales. They use aggregator processing, so they’re cheap and easy to set up.
For heavier-volume sales, payment gateways like Authorize.Net and PayPal Payflow Pro work better. These payment gateways also make auto-billing and storing credit card numbers possible.
Authorize.Net is the payment gateway industry leader. It has a £35 setup fee, costs £19 per month plus £0.10 per transaction. These costs are applicable only without the merchant account – other fees apply if you use both their payment gateway and merchant account.
Worldpay, the leading payment provider in the UK, offers different payment plans that include the payment gateway and other features. They have plans suitable for low-to-high-volume businesses and monthly fees of either £19.95 or £49.99 depending on the package. Gateway transaction fees and different fees specific to each package also apply.
Other major players offering both payment gateway and merchant account include Amazon Pay, Sage Pay and Braintree.
