Payment gateways: What they are, what they’re not, and what they cost.

Nov 20 2020 | PayPal editorial staff

Online transactions seem so simple and quick on the surface, but there are a number of processes working together behind the scenes to move funds from buyer to seller.
A payment gateway is part of that “magic” and below we’ll dive into: what a payment gateway is and what it does, if you really need one (you do, by the way), how a payment gateway differs from a payment processor, fees, and the PayPal payment gateway solution.
 

What is a payment gateway? 

The simplest way to think of a payment gateway is the secure technology that provides a bridge between your business and your customer.
 
Once a customer hits the ‘Buy Now’ button on your website, your payment gateway takes action. It securely sends your customer's credit card information from your website to the credit card payment network for processing. It then returns the transaction details and response from the payment network back to your website to tell you if the charge is authorized, allowing the order to be completed.
In the same way a point-of-sale terminal at a brick-and-mortar cash register looks at a card's chip to ensure the card is valid, a payment gateway helps ensure a payment is legitimate. Since you can't access the physical card when processing an online order, the payment gateway helps do that work for you.


Do you need a payment gateway?

As long as you accept (or want to accept) credit card payments online or on a mobile device, you’ll need a payment gateway. Without it, you won't be able to verify a customer's credit card information, process payments, or finalize the sale.
 
If your business is brick-and-mortar only, you might not need a payment gateway. Your point-of-sale terminal will authorize the credit card payment using the chip reader. But if you plan to offer a hybrid of online and offline sales, it can make sense to incorporate a payment gateway into both your e-commerce and real-world checkout process.


What's the difference between a payment gateway and a payment processor?

You'll often hear the terms 'payment gateway' and 'payment processor' used interchangeably, but they're different.

  • payment processor passes along the customer's credit card information to the issuing bank. Once the transaction is approved, it connects the issuing bank with your merchant account to transfer the funds. While a payment processor is a requirement to process the transaction, a payment processor alone doesn't help securely authorize the transaction.
  • Like a payment processor, a payment gateway also passes along the customer's credit card information and connects accounts together. But it also securely authorizes the transaction, ensuring you'll get paid. You need both for online sales, but using a payment gateway that’s different from your payment processor can give you flexibility to go with your preferred bank. And if you ever want to change your bank, you can do so without changing your integration or backend processes.


What to look for in a payment gateway.

Not all payment gateways are created equal. If you want to accept online payments, it's worth taking the time to research your options and find one that best fits the unique needs of your business. Here's what to look for:

  • Security: As a merchant, you need to protect your customers' credit card data. If a customer doesn't trust your website with their information, they're unlikely to complete the sale. If you want to accept credit cards online, ensure your payment gateway is PCI compliant.
  • Hosted versus self-hosted: A hosted payment gateway will send customers to a different website to enter payment details. This can make it easy to get started and helps ensure PCI compliance, but doesn't allow you to control the whole customer checkout experience. A self-hosted payment gateway collects the credit card information from your site, providing a holistic customer experience. But since this option puts responsibility for security on you, you'll need a self-hosted option that can provide PCI compliance.
  • Customer experience: While security is important, you don't want your customer to go all the way through the checkout process only to realize your website won't accept their preferred payment method. You need to make sure your payment gateway lets you process the payment types your customers prefer to use so they don't get frustrated or take their business elsewhere.
  • Implementation: Your payment gateway needs to connect your website and merchant bank account together with other processors. Choose a provider that makes it simple to implement and connect everything without a lot of hassle.
  • International capabilities: When you sell online, there's no reason to limit yourself to only your local market. As e-commerce becomes more global, you need to attract, nurture, and sell to customers internationally. That means your payment gateway needs to make it simple to accept more than just your local currency.
  • Optional features: Depending on your business, you may need extra features that other merchants don't, like additional fraud protection, buyer authentication or the ability to process recurring payments like membership fees.

What are average payment gateway fees?

Average payment gateway fees can vary widely, depending on the provider and your requirements. Expect a monthly fee ranging from $0–$25 and gateway fees of about $.10 per credit card payment. Also be aware that payment gateways sometimes have hidden fees that can drive up costs.
 

Hidden payment gateway fees to watch out for include: Set-up fees, a monthly fee, processing charges that may include a percentage of the sale plus a flat charge per transaction Fees for things like early cancellation of a contract, currency conversions, or processing minimums

The easiest way to get started is to go with an all-in-one solution.

If you're starting from scratch, you can get the gateway and processor in one package. This convenience saves you the hassle of implementing and managing two different providers and by reducing complexity, you also make it easier to help ensure all your security needs are being met and that the customer experience is seamless. The PayPal Commerce Platform gives you a payment gateway and payment processor all in one, making it simple to start selling. There are no set-up or monthly fees for PayPal Commerce Platform.
