What is a Payment Processor?
- Payment Processor
A payment processor is a company that facilitates credit card payments on behalf of a merchant by receiving, communicating, and relaying the cardholder’s information between issuing and acquiring banks.
[noun]/* ˈpā • mənt • prä • se • sər/
Processors work as a “middle man” to conduct payments. As long as the customer has the necessary funds available for the transaction and has been verified by their issuing bank, the transaction can be processed quickly.
Here’s how payment processors work:
Customers present their card to a merchant to pay for goods or services. Once those details are entered via online form or physical POS terminal, the information is submitted through a payment gateway. This is often included with the merchant’s payment processing account.
The customer’s payment credentials and transaction information are sent to the payment processor via the payment gateway. The processor then sends that information to the card network for approval.
The card network will notify the payment processor whether or not the payment request is approved or denied.
The merchant finishes the transaction with the customer.
After the transaction is completed, the payment processor requests that the issuing bank send the funds from the transaction to the acquiring bank.
The merchant receives access to the funds from the sale. Depending on the processor and type of account, the transfer could occur instantly or within a few business days.

Payment processing can be relatively swift if the processors and networks they work with have a streamlined payment gateway. However, if a third-party payment processor like PayPal or Venmo is used, it would be the third party who communicates with the network to facilitate payments. This extra step could cause delayed responses and fund transfers that could take several business days.
Determining the Best Pricing Model for Your Needs
First, you want to choose the company that best suits your budget. Pricing structures for payment processors tend to vary according to your industry, sales volume, and merchant status (standard versus high-risk processing). The three most common pricing models are:
#1 | Interchange-Plus Pricing
This pricing method includes the interchange rate plus a markup, which can either be a fixed amount or percentage-based.
This method can be less costly than the others, especially for businesses that process a large number of transactions.
Interchange rates can vary from transaction to transaction, making it difficult to predict costs month to month.
#2 | Flat-Rate Pricing
This pricing method ensures a single rate for all transactions through a given method, regardless of interchange rates and fees. This would mean you’d pay a set percentage on top of your transaction rate; for example, 3% of the total plus $0.25 for every transaction.
Flat-rates aren’t subject to fluctuation. You know what you’re getting into.
It could be more expensive than the other tiers if a company processes many transactions annually.
#3 | Tiered Pricing
This pricing method combines both interchange-plus and flat-rate pricing by sorting rates into grouped categories. To illustrate this, let’s say that you might pay 2% plus $0.15 for debit transactions and 3% plus $0.10 for credit card transactions. These rates and fees are variable, following a predetermined ruleset.
Tiered pricing offers predictability combined with competitive pricing.
If you are a high-risk merchant, or process a large number of payments overall, the costs associated with a tiered pricing scale could be very high.
Additional pricing details to think over:
- Most payment processors list their pricing details on their websites. Some will require that you contact them for an individualized quote.
- Some processors offer more than one payment method according to your industry, vertical, etc.
- Online transactions carry higher fees due to the increased fraud risk, as compared to brick-and-mortar sellers.
- The actual POS terminal can get expensive. If up-front costs are a concern, some processors allow you to take payments from a tablet or other device.
Other Things to Consider Before Choosing a Payment Processor
With few exceptions, there’s simply no way you can operate a profitable business without taking credit card payments. Which service provider should you choose, though? How can you tell which is best suited for your needs, though?
Beyond the pricing model, here are a few other things to consider before you choose a payment processor:
What About Processing Payments Online?
As mentioned above, online payments are similar to POS terminal payments but are not quite the same. To process payments online, your processor must expressly state that they handle online transactions and supply methods to facilitate those transactions through an online portal.
For instance, if you strictly take online payments, it might be worth taking payments through an aggregator like Square, which provides instant-payout options and increased security.
Otherwise, payment processing mostly look like this:
- The cardholder uses the online portal to make a payment.
- The merchant sends the secured transaction to the processor through the payment gateway.
- The processor verifies the cardholder and approves the transaction.
- The processor takes payment from the cardholder’s account and sends it to the merchant’s bank.
- A payment approval message is sent to the merchant.
- The merchant receives payment.

Many payment platforms like Etsy and Shopify support a ton of payment gateways and processors. If you want to use a single platform to manage both online payments and POS terminal payments, a third-party gateway may be required. If this is your situation, we recommend ascertaining your online presence ahead of your payment processing choice and factor dual capacity into your selection.
If you already have a brick-and-mortar shop to which you’re looking to add eCommerce (or vice-versa), you may need to consider switching processors.

Are There Alternatives to Payment Processing?
What if you don’t use a payment processor? How can you process payments?
It’s technically possible to run a business without a payment processor. However, you’d be limiting your business to just three payment options: cash, check, or money order.
Credit cards are the currency of our new digitized age. The majority of merchants today are aware that to turn a stable profit, they must follow consumer trends…meaning they must take credit and debit card payments to thrive.
Payment processing is just another cog in the commerce machine that can help propel your business to the next level. Choosing your processor based on the factors listed above will dramatically improve your chances of achieving a symbiotic relationship with processors and banks.
