PayPal Merchant Accounts
While PayPal personal accounts are free to use and free of charge to send receive payments, this is not the same for business users. PayPal charges business users on transactions made similar to all other payment gateways and processors. Detailed fees are available from PayPal in the UK but you should expect prices as high as 2.9% plus a small fixed fee per transaction (£0.30). You may not find this not to be the cheapest option on the market, but PayPal is one of the leading options due to the ease of integrating a fast and secure payment solution.
Setting up a pro solution will also require a degree of development skills to deploy successfully, though detailed documentation is readily available. It should also worth noting that Payments Pro customisation of the more advanced Payments Pro checkout will compromise PCI Compliance, and regular checks are needed to maintain conformity.
