Online payment services have become so commonplace, you may not give them much thought! Today, most banking and payments are done online— in fact, 78% of U.S. adults prefer to bank via mobile device or website.

If you’ve been manually processing payments, taking cash or cheques, you must be wondering: is there a better way? The great news is, yes! Today there are tons of options for online payment systems.

At its core, processing payments online is just about making it easier for your members, customers, or donors to support you in a way that’s convenient for them.

It is now essential to offer an online payment option, no matter your organization, if you want to be able to reach all of your potential customers, donors or members.

For example, Gary Rubens from the Ski Club of Washington DC began accepting online payments using WildApricot’s Membership Management Software this summer.

Within one month of promoting his club’s upcoming winter trip, all spots were filled and the club’s cash flow increased by $18,000, allowing Gary to cover all his deposits.

As Gary put it, “This is by FAR the earliest we have ever sold out a ski trip… Our President and Board are also tremendously impressed.”

Gary was able to reach people that may have not otherwise registered for the event had he not accepted online payments.

And he’s just one example of the thousands of organizations we work with every day that have seen incredible growth after accepting online payments.

We’ll give you the full picture about how online payment services work, why your organization needs one and the top providers for you to choose from. We’ve updated this list for 2023 so you have the freshest options!

Why are Online Payment Services Necessary?

In the digital age, almost everything is done over the Internet. Online payment services provide a number of advantages to your organization and your supporters, including:

  • Meeting standards and expectations
  • Speeding up the payment process
  • Saving you time with automation
  • Earning you more revenue
  • Keeping payment information secure

Meet expectations

People are increasingly comfortable paying online. When members, customers or supporters are ready to sign up, register for an event, or make a donation, they want to do it quickly and easily. In fact, websites that don’t support online payment can be seen as being out of step.

Speed up the process

There’s no question—online payments are faster than manual. You don’t have to wait for a check to arrive or clear with the bank! The whole process—from submitting an online payment to updating your bank account—takes a matter of seconds.

The results? Better cash flow for your organization and immediate confirmation of transactions. Prospective members won’t have to wait to join your organization and participants will know right away whether they have successfully registered for an event.

Save time with automation

Automated payments save you the trouble of depositing a check and recording the payment manually. Once you set up online payments for your website, they are automatically processed in a snap! You don’t handle or store any credit card information. Any updates to member records are handled automatically.

Earn more revenue

Having the systems in place to process payments online builds trust with your supporters—and helps you reach more people! By making your services, membership or events available to a wider audience, you’ll bring in more revenue for your organization overall.

Keep payment information secure

Speaking of trust, there’s no better way to give your supporters confidence in your organization than having a secure online payment processor. Your members get the peace of mind that their dues, event registration or donation is being tracked properly and won’t get lost or missed.

What Are Online Payments? Understanding Online Payment Terminology

There are several terms that are used almost interchangeably when describing online payments:

  • payment gateway
  • payment processor
  • payment provider
  • payment service or payment system
  • merchant account

Though they are distinct, with subtle differences, they all refer to a company, service, or application that acts as a financial middleman between your website and your customer, and between both of you and your bank accounts. Each facilitates the completion of online transactions, and the processing of online payments.

Payment gateway

A payment gateway is a service that receives the online payment request from your website and directs it to the payment processor. You can imagine the payment gateway as the digital equivalent of the point-of-sale machine you’d put your card in at the grocery store.

Payment processor

A payment processor is a service that validates the purchaser’s credit card details  (e.g., those of your member, donor, or supporter) and checks if they have sufficient funds in their account to cover the payment.

If the customer has sufficient funds, the transaction is authorized, and the funds are transferred from the customer’s account. The status of the transaction is transmitted back to the payment gateway which then sends a status message to your website. The payment processor company may also provide you with the equipment you need to accept in-person payments, such as a card swiper.

Payment provider

A payment provider (or payment service provider) is the company that operates the payment gateway or payment processor services. Some will operate both.

Payment service or payment system

Where a payment provider offers multiple types of payment gateways – with different features and pricing – each type is referred to as a payment service or payment system. For example, PayPal is a payment service provider that offers a number of payment services or payment systems such as PayPal Payflow Pro and PayPal Express Checkout (and here’s a great list if you’re looking for a Paypal alternative, or keep reading to see our review of various online payment systems at the bottom of this post).

Merchant account

A merchant account is another important term to understand. When an online transaction is successfully completed, the funds are transferred from the purchaser’s account to your merchant account, a special kind of bank account used exclusively to hold funds received from credit and debit card transactions. To accept online payments, you usually need to set up a merchant account with your payment provider. Funds accumulating in your merchant account are transferred to your organization’s bank account on a regular basis.

Payment gateway vs payment processor: what’s the difference?

Although the terms payment gateway and payment processor are sometimes used interchangeably, they actually refer to different parts of the payments process.

In an online transaction, the payment gateway is what authenticates the customer’s payment, whereas the payment processor is the mechanism that communicates the transaction between the bank and the merchant.

This distinction is important because, in a physical transaction, only the payment processor is needed. In a virtual transaction, however, an extra layer of authentication is necessary.

However, to make it even more confusing, the payment gateway and payment processor are sometimes combined into a single service known by either name. Some companies will manage both sides of the process, whereas others only handle one.

So, as you read through our list of payment processors, keep this simple but vital distinction in mind.

How the Online Payment Process Works

To fully understand how online payments work, let’s follow a transaction from start to finish. In this way, you can see how your website, your member or donor, and your payment service provider all interact.

To get started with online payment processing, you typically need:

  • a merchant account – though some payment systems (such as PayPal) do not require a merchant account or can provide you with one
  • an account with a payment service provider
  • a web page with a button (e.g. Join, Donate, Buy) that initiates the transaction process – you can use code provided by your service provider or specialized shopping cart software

Once you’ve set up your web page and connected it to an online payment system, visitors to your site will be able to pay online for products or services. The online payment process begins when the visitor clicks the button to pay online for membership fees or an event registration, or to make a donation or purchase something from your online store.

On the online payment form that appears, the visitor enters their credit card information and submits the transaction request. Depending on your online payment service provider, the form may appear on your website, or your purchaser may be redirected to a form on your service provider’s website.

The transaction request, along with the credit card information entered by the purchaser, is securely transmitted to the payment gateway operated by your payment service provider. The information is encrypted so that no one – including you – can view the purchaser’s personal and financial information.

Your payment service provider will then use a secure payment processing service – either their own or one provided by another company – to verify the purchaser’s credit card details and confirm whether the purchaser has sufficient funds to complete the transaction.

If the purchaser’s credentials are valid and there are sufficient funds to complete the transaction, your payment service provider will initiate a transfer of funds from the purchaser’s bank account to the merchant account associated with your website, and notify your website that the transaction has been approved. Depending on how your website is set up, that information can be used to automatically update records on your site (e.g., update your membership management or event registration database).

If the transaction is declined for any reason – such as invalid credentials or insufficient funds – no funds will be transferred, but status information will still be sent to your website.

The Top 11 Best Online Payment Systems For Your Organization

Now that we’ve gone through the anatomy of an online transaction, here are a few payment systems that you can use for your organization’s online payment processing needs.

We’ve included reasons why you might choose one processor over another, as well as an overview of the fees they charge per transaction.

(Note that this may not be exact for all providers, as some credit card companies will pass through additional fees, as will transactions that come through from outside your country, so it’s meant only as a comparison.)

With that in mind, here are the top eleven online payment systems for all your payment processing needs (and if you’re a nonprofit, check out our full guide to nonprofit payment processors here).

“As a small non-profit and an all volunteer board, we do not have the capability to run our membership sign ups and training registrations, by hand. We now have automated payments, registrations, renewals and are able to communicate in an instant with our membership. It is also very nice to have all of this with a user-friendly website in one place!”
