From the customers’ perspective, it is as simple as tapping or swiping their credit card on the terminal. However, several parties are involved on the business side to facilitate the credit card transaction. The credit card transaction involves the merchant, the payment gateway or terminal, the processor, the acquiring bank, the card network, and the issuing bank.
Credit card processing involves much more than simply receiving credit card payments. It also impacts how many transactions are approved, how many are fraudulent, when funds are deposited into the business’s account, how the business creates its reports, customer chargebacks, and how much the business pays to accept credit card payments. A robust credit card processing system makes customers’ experience with the business easier and improves the business’s back-office operations. A weak credit card processing system makes it hard for the business to manage its finances and operations.
Why Businesses Need the Right Credit Card Processing Setup
In 2026, businesses have many choices for their credit card processing solutions. However, the best solution for them will include factors such as transaction speed, online and in-store transactions, transaction disputes, data security, and whether the solution is suitable for their business model.
These businesses will likely outgrow their initial credit card processing solution. At the beginning of the business, or as it begins to boom, the credit card processing company they choose will work for them. However, as they begin to process more transactions and charge higher prices for their products or services, they will likely need a more advanced credit card processing solution to run effectively.
Who This Credit Card Processing Guide Is For
This guide is most useful for business owners who are considering which of the following business types might be best suited for a credit card processing company:
- small business starting with no experience with credit cards
- ecommerce business
- retail or restaurant business
- service business
- subscription business
- finance department of a business
- business founders
- merchants that wants to understand credit card processing fees more clearly
The more dependent your business is upon credit card payments, the more important it is for you to understand the basics of how credit card processing companies work. Furthermore, even if you are not changing your current credit card processor, understanding how credit card processing companies work will allow you to better understand the various aspects of credit card processing fees and how they apply to your small business.
Types of Credit Card Transactions
Credit card payments can occur in several formats. Card-present transactions involve swiping, dipping, or tapping a physical card at a POS terminal. These typically have lower processing fees due to reduced fraud risk. Card-not-present transactions, such as those processed through online stores or over the phone, carry higher risk and costs. Some platforms also support recurring billing for subscription-based models, as well as tokenized payments that let returning customers pay with one click. High-risk industries like nutraceuticals, travel, and jewelry multi-level marketing companies often rely on card-not-present transactions, which makes fraud prevention and merchant services selection even more critical. Understanding which transaction types your business will use most frequently helps you choose the right setup and avoid service disruptions.
Credit Card Processing Options for Different Business Types
Most businesses do not need the same processing setup. A coffee shop, an online subscription company, a B2B invoicing business, and a higher-risk ecommerce brand all create different payment needs. That is why “best processor” is usually the wrong question. The better question is which model best fits the business.
| Option | Best For | Main Strength | Main Tradeoff |
|---|---|---|---|
| Flat-Rate Processor | Small businesses and simple retail | Easy pricing and fast setup | Can cost more at scale |
| Interchange-Plus Processor | Growing businesses that want more pricing transparency | Cleaner fee visibility | Statements can be more complex |
| Subscription-Pricing Processor | Higher-volume businesses | Lower effective cost in some cases | Monthly platform fee |
| Gateway + Merchant Account Stack | Online businesses needing more flexibility | Better control over checkout and billing logic | More setup than all-in-one options |
| High-Risk Merchant Account | Businesses with higher underwriting friction | Better fit for harder-to-place models | Custom pricing and more documentation |
For many businesses, the right answer changes over time. A flat-rate setup can be a strong starting point, but it may stop being the best fit once volume, complexity, or risk profile changes.
Understanding Credit Card Processing Fees
Processing fees are the costs a merchant pays for each credit card transaction. These are generally broken down into interchange fees (charged by the card networks and issuing banks), assessment fees (collected by the card networks), and processor markup (the fee your payment provider adds). You might also encounter monthly gateway fees, PCI compliance fees, or batch processing fees.
For high-risk merchants, these rates are typically higher due to a higher risk of chargebacks or fraud. Some providers offer tiered pricing, while others use interchange-plus pricing, which offers greater transparency. Merchants should request a full merchant services statement analysis to understand exactly what they’re paying for and identify opportunities for savings. Over time, even small percentage-point differences can significantly impact your revenue.
Fraud Prevention in Credit Card Processing
As credit card fraud continues to rise—especially for card-not-present transactions—merchants must proactively secure their systems. That means using PCI-compliant software, deploying address verification (AVS) and CVV checks, and enabling tokenization for repeat payments. Providers may offer machine learning fraud detection tools, real-time transaction monitoring, or manual review workflows for high-ticket items. You’ll also want to verify whether your merchant account provider includes chargeback mitigation services, especially if you’re selling in regulated categories. Fraud doesn’t just cost you money—it can cost you your merchant account entirely. Understanding your processor’s risk tools, how often they update their algorithms, and what you’re liable for in a disputed transaction is essential to long-term success.
Understanding BIN and Non-VBV Concerns
A lesser-known but important factor in credit card processing is the Bank Identification Number (BIN) and whether a card is enrolled in Verified by Visa (VBV) or Mastercard SecureCode. Non-VBV cards may be easier to use in global eCommerce but carry higher fraud risks and may be flagged by more conservative payment providers. Merchants processing high volumes of international transactions should be aware of how their processor handles BIN routing, whether they allow non-VBV cards, and how they mitigate associated fraud risks. In certain industries, a high rate of non-VBV transactions can lead to elevated decline rates or even account termination. Understanding these nuances helps you protect your merchant account while serving a broader customer base.
Best Credit Card Processing Companies (2026)
The best credit card processing company for your business depends on what kind of fit you are looking for in your payment processing software.
- Payment Nerds is best for people who need help finding the right payment solution for their business, especially if their business is growing or particularly complex.
- Square is best for retail and service businesses that want a lot of features and don’t want to worry too much about the payment details.
- Stripe is best for people who work with e-commerce or have an online business with high levels of complexity.
- Helcim is best for people who want to see interchange-plus pricing options rather than a more complex, custom pricing structure.
These are fit-based recommendations, not universal rankings. The right processor depends on how you sell, how customers pay, how much control you need, and how much complexity your business creates for the payment stack.
Credit Card Processing Costs Explained
There are three components to credit card processing fees: interchange fees, assessment or network fees, and the processor markup. Interchange fees go to the card issuer. Assessment or network fees go to the card brands. The processor markup goes to the companies that process the cards.
Credit card processing fees can be confusing at first. Some companies use a flat-rate pricing model. Other companies use interchange-plus pricing, where the interchange and assessment fees are passed through to the merchants, and the company adds its processing fees on top. The best model for credit card processing fees depends on the nature of the business. A flat-rate pricing model is easier to understand, while an interchange-plus model offers better visibility and economics for credit card processing fees.
Common Credit Card Processing Mistakes to Avoid
The most common mistake when selecting a credit card processing company is basing the decision on only the headline rate. There are several other aspects of the processing company that will ultimately affect its total cost over time.
Another common mistake is not understanding how the processing company fits into the business model. Not all processing companies are a good fit for every type of business. Some have better features for handling subscriptions, while others may be a better fit for higher ticket sizes. Additionally, many businesses get into trouble by ignoring the company’s PCI responsibilities, not understanding fraud settings, or failing to understand the impact of certain actions on the account.
Key Parts Of How Credit Card Processing Works
The Customer Starts The Transaction
Every transaction begins when the customer presents their payment credentials. Whether they are using their chip card, using contactless technology to pay, using their mobile wallet, or manually entering their card information online, they have initiated a transaction and the payment information has been captured by the merchant’s system. This very first step in the process is important. How the customer completes their purchase will have an impact on many aspects of the transaction, including how much the merchant will pay for the transaction and the risk of fraud with that transaction.
The Gateway Or Terminal Sends The Data
Once the customer has begun the transaction, the business’s payment terminal or gateway will send that transaction to the processor. This technology will transmit the transaction information from the business to the processor. For in-person businesses, the customer will typically interact with a countertop terminal. For online businesses, the transaction will go through a payment gateway. In either case, the organization that sends the transaction data to the processor is essential to ensuring that the customer’s transaction is processed successfully.
The Processor And Acquirer Route The Request
The payment processor receives the transaction data from the terminal. The processor then routes the transaction to the acquiring bank so that the transaction can be made. This bank accepts the merchant’s payments and allows their cards to be used by the merchant. It is also during this phase that the processor performs many of their functions for the merchant, such as formatting the transaction data and managing their risk settings. The fit between the merchant and its merchant account is important for this step. The functions performed by the processor and acquiring bank are part of the risk and funding relationship between the merchant and acquiring bank.
The Card Network Passes It To The Issuer
After the transaction is routed by the acquiring bank to the payment processor, the transaction goes through the card network. The card network is the organization that sends the transaction from the acquiring bank to the cardholder’s issuing bank. The different card brands do not necessarily perform the same functions. Mastercard, Visa, American Express and Discover all have slightly different functions during this step in the transaction process.
The Issuer Approves Or Declines
The issuing bank receives the transaction and either approves or declines the transaction. This decision is made based on the customer’s available funds and credit, any signals of potential fraud, and the customer account status. When the issuing bank approves the transaction, the customer will see their payment reflected on their purchase. However, their payment to the merchant has not yet been made at this point.
Clearing, Settlement, And Funding Happen Afterward
Now that the transaction has been authorized, it must be cleared and settled so that the merchant is appropriately funded for that transaction. While many merchants are unaware of this process until they see that their bank deposit is not reflecting their sales figures, there are two crucial steps to complete. Clearing of transactions occurs between the merchant and the bank, during which transaction details are exchanged between the two and the fees for that transaction are calculated. Following this step is the settlement of the transaction, which is when the funds are sent to the merchant’s account so that they can be paid to the merchant. This is also when many of the issues with transaction deposits begin. Sales figures for the merchant will not necessarily reflect the funds that are deposited into their bank account due to various factors. Understanding how transactions are settled is one of the easiest ways for merchants to increase their proficiency in accounting and reconciling their books.
How to Choose the Right Payment Processor
When comparing credit card processors, start with your sales model. If you’re a retail store doing in-person sales only, you need something different from a business that stores its cards on file online. Both of these models are going to be completely different from a company that sends out invoices for services provided or a company that receives recurring bills for a subscription model.
Look at the factors that will have the most influence on your business operations when it comes to credit card processing companies. These factors include credit card processing pricing model, deposit timing, reporting, recurring billing software, ecommerce and POS compatibility, fraud software, and provider transparency.
FAQs About Credit Card Processing
Q: How does credit card processing work?
A: Credit card processing companies receive the payment request from the merchant’s point-of-sale (POS) system. The payment is sent to the processor, then to the credit card network (Visa, Mastercard, etc.), and finally to the customer’s bank to authorize the transaction. Once authorized, the transaction is cleared and settled with the merchant.
Q: What are credit card processing fees?
A: Processing companies charge merchants fees for processing credit card transactions. The fees include the interchange fee, the network fee, and the processor’s markup on the transaction. Some companies include all of these fees in a flat rate, while others list them separately.
Q: What is the difference between a payment processor and a merchant account?
A: A payment processor handles credit card transactions for merchants. A merchant account enables merchants to accept credit card payments from customers. These two services can be bundled or offered separately.
Q: What is interchange?
A: The portion of the credit card transaction fee that goes to the merchant’s card issuing company is known as the interchange fee. The interchange rate is set by each credit card company and can vary based on the type of card, the way the transaction is processed (over the phone, in person with a POS terminal, etc.), and the type of merchant.
Q: Is flat-rate pricing for credit card processing companies better than interchange-plus pricing?
A: Flat-rate pricing models are easier to understand and implement than interchange-plus models. However, interchange-plus pricing may be better for merchants looking for more detailed pricing and processing a high volume of credit card transactions.
Q: Why does PCI compliance matter for credit card processing companies?
A: Any business that accepts credit card payments is responsible for helping to protect the data associated with those payments. While credit card companies and processing companies usually handle the majority of data security for a merchant, the merchant must still be aware of its role in protecting that data.
