Key Takeaways

What Is a Credit Card Processor?

A credit card processor is a company that connects merchants with different credit card companies. They are also known as acquirers.

The biggest way these processors can help your business is to accept electronic payments from customers using their credit or debit cards. There are quite a few benefits to this. Most importantly, you get to eliminate the middleman when it comes to taking payments.

Credit card processors also offer more than just accepting consumer credit cards. They will often process debit transactions as well, including ACH and eCheck transactions.

How Do Credit Card Processors Work?

The way the credit card payment processing system works is rather complex. We won’t get into all of that here, but we do want to give you the basics of how it works, so you can better understand how credit card processors are able to help.

Here’s how it breaks down. When a customer wants to purchase something, they will swipe their card or enter their information at checkout. These machines usually have a slot for the customer to slide their card.

The first thing that’s happening is that your customer is entering their information into the machine. The machine then sends it over to the processor for processing. They are verifying that there are enough funds in your account and other details like this. Once everything checks out, the payment will be authorized. The authorization comes back from the processor and tells you that you can go ahead and collect payment from your customer.

From there, the merchant is responsible for collecting the funds. Once your customer pays their bill, they should receive a receipt with all of their information on it. At this point, the process is essentially over until it’s time to send out bills or payments.

What Does a Processor Do?

As we have already mentioned, processors help you take payments from your customers. Another important function of the credit card processor is that it will provide your business with a virtual terminal. This is where you can set up different point-of-sale transactions and check your account balance.

In addition, processors work to secure your information as well as keep it safe from fraud. As a business owner, you may not have the resources or knowledge to protect your data from hackers or other threats. By working with a credit card processor, you can rest easy knowing that they are dealing with this aspect of your business.

What Do Credit Card Processing Companies Charge?

When you’re looking into credit card processors, there are a few main fees that you will have to consider. You need to be aware of them so you know what kind of budget you’ll need.

The first is a per-transaction fee. This is a small fee that gets charged every time your customer uses their credit card to make a purchase. These are also known as an interchange fee or credit card processing fees. These can be a flat rate or tiered.

Next, there are monthly fees. These may apply even if you don’t process any transactions during a given month. Be sure to ask about this fee before you sign on with a credit card processor so that you know what these costs will be.

There are also fees that are charged when you make refunds to customers. This can be a downside for many business owners. It is important to know about the potential costs involved before starting any merchant account agreement.

Why You Need a Credit Card Processor

There are many reasons why you need a credit card company as part of your business. There are countless benefits to accepting credit cards at your point of sale. It is really the only way that you can expect to be successful in this day and age.

For starters, your customer will appreciate being able to use their card when making a purchase from you. It makes the process much simpler for them. It also increases your chances of them wanting to come back and shop with you again.

It also allows for simple record keeping. Since everything is handled electronically, it makes the job of keeping track of payments much easier. This can help you to get paid faster and work more efficiently.

Credit card payments are also very secure. This should be one of your primary concerns as a business owner. Credit card processors will keep your information locked down and protect it from hackers or other forms of data theft.

Now that you know more about processors, let's get into the list of the top ten best credit processors.
