- U.S. consumers increasingly prefer credit card payments over cash.
- Optimizing customers’ credit card payment experience takes in-depth research.
- Card providers, equipment, costs, and fees top the list of credit card payment system priorities.
- This article is for merchants and small business owners looking for a more efficient consumer payment experience.
No matter what type of business you have, it’s important to accept credit cards payment from your customers.
Consumers prefer credit cards over cash payments by a significant margin. According to a 2020 study by the Federal Reserve, 27% of U.S. consumers opted to use credit card payments, while 19% preferred paying cash. Every year, the Federal Reserve reports, the use of bank cards over cash expands.

As you adjust to a new digital-based payment marketplace, weaning you off cash payments and pushing payment models to the credit card side of the aisle makes good sense – if, that is, you are prepared for the shift to increased plastic payments.
Job one is choosing the right credit card payment and service provider.
That choice can be problematic for your business, as there are hundreds of payment processing companies to choose from and several factors to consider before selecting a processor. You want to look for the best credit card processing company for your business, considering factors like low rates, few fees, and month-to-month contracts.
How to start accepting credit cards
If your business is new or not yet accepting credit card payments, you’re probably wondering how to accept plastic and how much it will cost. These steps will walk you through the process of setting up credit card processing for your business and provide questions to contemplate.
- Decide which type of processor will be the best fit for your business. Should you work with an aggregator, a merchant services provider, or a direct processor? How do you know which type of credit card processing service you need?
- Identify how you plan to accept credit cards, and evaluate equipment options. Do you plan to accept credit cards online or at a brick-and-mortar store, or do you prefer a mobile credit card processing solution that uses a smartphone and a card reader? Do you want to accept payments multiple ways?
- Learn about credit card processing fees and pricing models. This helps you know what to look for, and whether you’re getting a good deal or paying more than you should.
- Call three or more credit card processing companies for pricing quotes. Many service providers customize their rates for each client, so you need to figure out a good deal for your unique business. You also need to know what information you should never give a sales rep until you’re ready to sign up with a processor.
- Read the contract before you choose a processor. Find out which terms are negotiable, where to find hidden fees and when you should look for a different option.
- Apply for a credit card processing account. Once you’ve decided which payment processor you want to work with, it’s time to apply for a merchant account.
Tip: If you plan to use a point-of-sale system to accept credit cards, see our reviews and recommendations for the best POS systems.
1. Decide which type of processor will be the best fit for your business.
There are multiple ways to integrate a credit card payment service into your unique business.
For example, you’ll need to choose between a card payment service that works with individuals or opt for a provider that serves only businesses. Additionally, you’ll need to factor in the average monthly volume of credit and debit card payments that you accept.
To get the job done right, start by evaluating the following credit card payment processing solution models.
If you’re an individual who wants to accept credit cards for personal use – for example, if you want to accept credit cards at a garage sale or for freelance work, or if your business isn’t yet official – Square is a good option.
Square is one of the few payment processors that work with you individually and works with your business. You will pay a small fee each time you accept a credit card payment, and there are no monthly or annual fees. Square gives you a card swiper, or you can buy an inexpensive chip card reader from the company.
If you desire the ability to accept credit card payments from friends, family, or other people you know and trusts – such as the friends you split the bill with at dinner last night – you can use peer-to-peer payment services like PayPal, Venmo, Apple Pay Cash, Google Pay or Zelle.
Tip: You don’t want to use a P2P payment service to accept payments if you don’t know the individual. Beware that buyers can reverse transactions, such as in Venmo payment scams.
Small, monthly cash amounts
If your small business processes less than $2,500 per month or has small sales tickets, you want to work with a payment facilitator like Stripe.
Facilitators like Stripe are cheaper to use at this processing volume because you pay only a small fee – expressed as a percentage of each sale and, sometimes, a per-transaction fee – for each credit or debit card payment you accept. Even though payment facilitators charge a higher percentage than other types of payment processing rates, you save money because you don’t pay any other fees.
There’s no setup fee, the monthly fee (such as statement and payment gateway fees), or annual PCI compliance fee.
Tip: Consider PayPal alternatives if you’re looking for low-volume credit card payment processors.
Payment facilitators – also called mobile credit card processors or merchant aggregators – sponsor multiple merchants under their master merchant accounts. This makes it easier to sign up for an account, and there are fewer fees to pay, but they can be more restrictive.
Make sure to carefully read the user agreement to ensure the goods or services you provide aren’t prohibited. Additionally, be aware that processing irregularities – such as abnormally large transactions or a sudden spike in monthly volume – may cause your card processor to freeze your funds, which can restrict cash flow.
Key takeaway: If you have small sales tickets, you can save money by choosing a credit card processing company that charges only a percentage of each sale. Some also charge a small per-transaction fee – usually 10 to 30 cents – but this adds up quickly if your sales tickets are small.

Larger monthly sums
If your small business processes more than $3,000 per month or has large sales tickets, consider a processor with lower rates like Payment Depot. These payment processing companies can install a merchant account for you.
Even though these processors may charge fees that the aggregators don’t, they offer lower rates, which saves you money when you’re processing larger sums of money every month.
ISOs and MSPs
Independent sales organizations (ISOs) and merchant service providers (MSPs) that resell merchant accounts from direct processors offer credit card payment options for your small business, too. Because you’re still processing a lower payment volume than large businesses, you’re not likely to get better rates from direct processors. Even so, you’ll want to shop around to find low rates, few fees, and a month-to-month contract.
Tip: If you process a low volume of credit cards each month, look for a payment processor that doesn’t impose a monthly minimum – a minimum dollar amount of credit card processing fees you must generate each month.
If you process a high volume of sales each month, you could also consider working with a direct processor like First Data, Wells Fargo Merchant Services, or Bank of America Merchant Services. These companies tend to be better suited for large businesses, but they will also work with your small company.
Direct processors provide merchant accounts and have relationships with banks and credit card brands. Again, you’ll want to compare shops for favorable rates, fees, and contracts.
If you are looking for a point-of-sale system (POS), check with the company to find out which credit card processors the POS system is compatible with, as that may limit your options. Some require you to use their in-house processing services, but the best credit card merchants allow you to work with third-party payment processors so you can shop around for low rates and fees.
2. Identify how you plan to accept credit cards and evaluate equipment options.
You’ll want to accept credit card payments wherever and however, customers want to pay. That’s the case no matter what type of credit card transaction you accept, including: in person at your business or another location, online, over the phone, and through mobile apps.
Once you decide how to accept credit cards, address what kind of credit card processing equipment you’ll need. The best processing equipment will meet these standards.
EMV chip cards
All card readers can accept magnetic stripe cards, but you want a model that can accept EMV chip cards (Europay, Mastercard, and Visa microchip card payments). EMV card technology protects you from liability for fraud occurring at the point of sale. EMV card readers also allow you to skip signature authentication, which can speed up the checkout process.
Ideally, the card reader will also have NFC technology, which allows you to accept mobile wallets like Google Pay and Apple Pay. This way, you won’t have to upgrade your equipment again as this payment method becomes more popular.
Nearly every credit card processor sells processing equipment, and in most cases, you’ll get at least your card reader from the company. If you already own a terminal, the processor may be able to reprogram it, though there is sometimes a fee for this service. If you want to buy peripherals from a third-party vendor, you’ll need to check with the processor for compatibility.
Upfront payment methods
Plan to buy your credit card payment processing equipment upfront, as installment plan payment models can escalate in price. One merchant signed a lease for $99 per month with a 48-month term for a machine – in effect, paying $4,800 for a machine that costs $300 to purchase. The FTC cautions against leasing credit card processing equipment for the same high-cost reason.
Be wary of free credit card processing equipment, as you may be charged higher rates and additional fees – such as an insurance fee or some sort of equipment maintenance fee. Most payment providers also require you to return the equipment when you close your account.
With those tips in mind, let’s examine several solid credit card payment processing hardware and technology options.
Mobile credit card reader
This is a portable device you use with a smartphone or tablet and a credit card payment app. Some models plug into the headphone jack or lightning connector on your phone or tablet, but many newer models connect via Bluetooth. Many processors give customers a free credit card swiper, but you should upgrade to a model that accepts EMV chip cards and NFC contactless payments. These usually cost less than $100.
Mobile card readers can be used as stand-alone devices or as part of a larger system. You could utilize these if your company accepts credit cards on the go. They’re also useful to process transactions from anywhere in the store during busy seasons, or if your company only runs a few transactions each day.
Credit card terminal
This type of card reader often has a built-in receipt printer and keypad for PIN debit transactions. Countertop models connect via dial-up or Ethernet. Wireless models connect via Bluetooth, Wi-Fi, 3G or GPRS. All new models are EMV compliant so that you can accept chip cards, and most have NFC technology to accept mobile payments. Credit card terminals usually cost between $150 and $600.
Payment terminals are the most common type of processing equipment. They would be ideal for your business should your firm need a card reader to connect to or work alongside a POS system, or if you don’t need the credit card processing system to do anything but accept payments.
This is a complete checkout station that typically includes software, a tablet or touchscreen, a card reader, cash drawer and a receipt printer. Some systems have built-in card readers, while others connect to or are used alongside a credit card terminal or mobile credit card reader. You can add barcode scanners and other peripherals.
Available for purchase from merchant account providers or POS companies, POS systems’ pricing depends on the type of system you choose. Tablet-based systems that work with third-party hardware are usually the least expensive. These systems are best for your company’s physical location, particularly if you want to connect to other business software. Review our best accounting solutions for software recommendations to consider.
If you want to accept credit cards online – for example, if you sell goods or services through your website or an e-commerce platform – you need a payment gateway. Most credit card processors can set you up with this technology and help you connect it to your site. Some processors have proprietary payment gateways, and others set you up with a third-party gateway like Authorize.Net.
There’s usually an additional monthly fee for this service, and some processors charge a gateway setup fee and another per-transaction fee.

3. Learn about credit card processing fees and pricing models.
Credit card processing fees can be confusing, and it’s beneficial to fully understand credit card payment fees. This will help you negotiate the best transaction rates for this type of service.
These are the three common types of credit card processing fees: transaction, service, and incidental fees.
- Transaction fees (or rates): These are the fees you pay for every transaction. They’re usually expressed as a percentage of the sale plus a flat fee for each exchange. For clarity, we refer to these fees as rates. Processors have different methods of calculating and charging these rates – also known as pricing models – which can make it tricky to figure out what you’ll actually pay and whether or not you’re getting a good deal.
- Service fees: These are monthly and annual accounts maintenance fees, such as statement fees and PCI compliance fees. They can also be standard fees, but the best credit card processors don’t charge service fees.
- Incidental fees: These are fees that you’re charged on a per-occurrence basis; they’re triggered by certain actions on your account, such as chargebacks. These are also standard, but some credit card processing services may not include them.
The three most common pricing models are flat-rate, interchange-plus, and tiered pricing. Here’s how each option works, along with information on which pricing model is best for your business type and size.
Flat-rate pricing is usually charged by payment facilitators like Square and PayPal. There are different rates based on how you accept your customers’ credit and debit cards. This is the simplest pricing model.
Here’s an example of flat-rate pricing using PayPal’s transaction fees:
- Card present: For cards that you accept in person using a chip card reader or a magstripe card reader – either in-store or on mobile – you pay 2.7% of the transaction. This is the lowest rate because this payment method has the lowest risk of fraud.
- Card keyed in: If your customer’s card doesn’t work and you have to key it in, or if you accept a payment over the phone and key in the card info, you pay 3.5% plus 15 cents for the transaction. This method is more expensive because you don’t use the physical card to process the transaction, so there’s an increased risk of fraud.
- Card online: When you accept an online payment – through your website, a payment page linked to your website, or an electronic invoice – you pay 2.9% plus 30 cents. This method costs more than the card-present method because it’s a remote transaction. However, this method is cheaper than the keyed-in rate because it requires your customer to supply additional verification information – such as the CSV number and their address.
Interchange-plus may be the best option for your business. Industry experts recommend interchange-plus pricing because it’s more transparent than the other pricing models: it reveals exactly how much of a markup you’re paying the service provider.
Interchange fees are set by the card associations – or card networks – that pay the banks involved in the transaction for moving money from your customer’s credit card account to your company’s bank account. There are hundreds of interchange rates, depending on the type of card and the brand. The card networks charge a small fee for each transaction. These rates are the same for every processor – regardless of whether they’re a payment facilitator, ISO or MSP, or direct processor – and they’re non-negotiable. The only debatable part of a transaction rate is the processor’s markup.
With this model, the processor passes on to you the interchange rates and card association fees charged by the credit card networks – Visa, Mastercard, Discover, and American Express – and adds a markup percentage and per-transaction fee.
When you receive a quote for this pricing model, it’s only the processor’s markup percentage and per-transaction fee that you’ll be charged. So, for each transaction, you’ll pay this amount on top of the interchange rate.
Here’s an example of interchange-plus pricing, using Helcim’s transaction fees. When you accept a credit card payment in person using an EMV chip card reader or a swiper, these are the rates you’ll pay:
- Processor’s markup: 0.25% plus 8 cents. This is the rate you’re quoted when you ask for interchange-plus pricing. This is the only negotiable portion of this rate.
- Interchange rate: 1.65% plus 10 cents. This is an example of what it might cost to process a retail transaction using a Visa Rewards credit card.
- Card association fee: 0.15% plus 2 cents. This is the fee that Visa charges for credit card transactions.
Consequently, for this transaction example, the full rate would be 2.05% plus 20 cents.
Did you know? The best processors offer interchange-plus pricing to all their customers and post their rates online. But most of the time, you have to specifically ask for it, and you may need to jump through hoops to qualify for it – such as processing a certain volume of sales each month or working with the company over an extended period.
Tiered pricing can be a good option if your customers typically pay in person using regular debit cards, though it can be expensive if they prefer to use premium rewards, and corporate or international credit cards. Most processors prefer this pricing model, but industry experts advise against it, as it’s less transparent than others.
- There’s no way to know exactly what the processor’s markup is, as each processor sets its own tiers and decides which interchange rates fall into each tier.
- Most processors don’t post tiered rates in full online. Instead, they advertise teaser rates that apply only to regular debit cards accepted in person. Many sales reps don’t disclose how many tiers, the pricing for each tier, or what types of cards and transactions are included in each tier unless you specifically ask for this information – leaving you with a surprise when you get your first bill.
- Transactions can be downgraded for various reasons, resulting in higher rates than those you were quoted. When you call for a quote, ask which actions can cause a transaction to be downgraded.
This list of credit card payment processors was made from Business News Daily’s best credit card processing providers:
|Merchant One review||Best for easy approval|
|Clover review||Best for POS|
|National Processing||Best for low transaction rates|
|ProMerchant review||Best for high-risk businesses|
|Payment Depot||Best for high transaction volumes|
|Square review||Best for growing businesses|
|Flagship Merchant Services||Best for flexible terms|
|Helcim review||Best for established businesses|
Tip: When you call for a quote, ask for interchange-plus rates. Otherwise, be sure to ask how many tiers there are, the rate for each tier, and which types of cards and acceptance methods are grouped into each tier. There are usually three tiers: qualified, mid-qualified and nonqualified. Some only have two, though, and there may be separate tiers for debit and credit cards.
In addition to processing rates, most full-service credit card processors charge an assortment of fees to maintain your account and provide customer support. Payment facilitators don’t typically charge these fees. Before you sign a processing contract, be sure to read it and make sure you’re aware of all the fees that the processor charges so you won’t be shocked when you get your first bill. Here are the most common service fees:
- Monthly fee: Also called a statement fee, this covers the processor’s cost of preparing monthly statements and customer service. It usually costs $5 to $15. It may be higher if it includes a gateway fee and a PCI compliance fee. If you choose to receive paper statements by mail, there may be an additional cost.
- PCI compliance: This fee is usually charged annually and costs around $100, though some processors either include it with the monthly fee or charge it quarterly. For this cost, service providers help you certify that your business complies with PCI guidelines. If you fail to establish your compliance, you’re charged an expensive PCI noncompliance fee each month until you are certified. Some processors offer to waive this fee for the first year when you sign up for an account. Payment facilitators are PCI compliant, so their clients don’t have to certify and pay this fee.
- Gateway fee: If you accept payments online, you need access to a payment gateway. Usually, this fee is charged monthly and costs about as much as the monthly fee, but some processors also tack on a small per-transaction fee.
- Monthly minimum: If you process a low volume of transactions each month, you want to look for a provider that doesn’t charge this fee, as it’s normally calculated against the processing fees you generate – not the full dollar value of each transaction. Usually, this minimum is $25, though some processors set it higher. Be sure to ask the dollar amount that you need to process each month to satisfy this requirement.
- Incidental fees: Some fees are only charged when certain actions have taken place. For instance, if a customer initiates a chargeback, you will need to pay a chargeback fee. If you use the processor’s address verification service (AVS) or call its voice authorization center for fraud-prevention checks before you process a transaction, you pay a small fee. Again, be sure to read the contract in full before signing up with a processing company, so you know precisely what fees to expect.
4. Call three or more credit card processing companies for pricing quotes.
The best credit card processor for your business is the one that offers you the best value – with low and transparent rates, no hidden fees, and either a month-to-month contract or pay-as-you-go service. Though many of the best credit card service providers post their pricing online, some don’t, preferring to customize their rates for each client. You should plan on calling at least three processors, and requesting price quotes and a contract to review, so that you can compare rates and fees for your specific business.
Even if all top credit card processors on your list post their pricing online, it’s a good idea to call and speak with a sales rep because there may be a promotion available, or you may be able to negotiate a better deal. It also gives you a taste of the company’s customer service quality, which can be an important consideration as you’re choosing a service provider.
5. Read the contract before you choose a processor.
No one wants to read the contract before signing up for a service, but with this industry it’s necessary. If you sign up with a full-service processor, you risk being locked into its services for several years, paying more than you expected. If you sign up with a payment facilitator, you may find out too late that it has certain processing limits or doesn’t support businesses in your industry, resulting in frozen funds or a closed account.
The best credit card processing companies provide their services on a month-to-month or pay-as-you-go basis, and don’t charge any early termination fees.
Used by ISOs, MSPs, and direct processors, standard contracts typically have three parts: the application, the terms of service and the program guide. Some applications have links to the terms and guide, but most often, you’ll need to ask the sales rep to send these documents to you separately.
- Application: Usually, this form includes credit card processing rates and some fees. It asks for your bank information, Social Security number and signature. Don’t provide personal information until you’re ready to sign up for an account, have read the contract in full, and have verified that the rates and terms are correct. Most contracts include a personal guarantee that allows the processor to collect money from you directly if your business can’t pay its processing bills, and allows it to perform credit checks on you.
- Terms and conditions: This document describes the length of the term and additional fees that your company may incur. Most have three-year terms, and automatically renew for one or two additional years if you don’t cancel in writing within a 30- to 90-day window. One clause to watch out for is “Additional Services.” Note that it doesn’t explain exactly what these additional services are or what they cost, but does mention that you have a short window – usually 30 days – to opt out if you don’t want these mystery services and fees.
- Program guide: This is where you’ll find cancellation instructions and the fees that apply if you decide to close your account. Sometimes processors don’t provide the program guide up front, and if you don’t ask for it, it will be tucked in with the processing hardware you order. If you sign a standard contract and then need to cancel your account before the end of the term, you will be charged a steep early termination fee for hundreds of dollars. Some long-term contracts also have liquidated damages clauses that can cost you even more money. Sneaky processors may claim not to charge early cancellation fees, but instead charge early termination fees (ETFs), early deconversion fees (EDFs), exit fees or lost profit fees.
Key takeaway: If the processor you are considering has a lengthy contract, ask your sales rep if month-to-month terms are available. Also, request to waive the early termination fee and any liquidated damages.
Most payment facilitators have user agreements instead of contracts. These are much shorter, but still important to thoroughly read. You want to check the list of prohibited goods and services to ensure the processor will work with your business. You also want to read the processing contract terms to find out if there are any processing limits, to make sure they won’t affect your business. One factor to keep in mind is that aggregators are very risk-averse and will freeze your funds if there’s anything about your transactions that looks suspicious, such as a sudden spike in volume or transaction size.
6. Apply for a credit card processing account.
This is the easy part! Once you’ve decided which payment processor you want to work with, and have read the contract to verify that the rates and fees match what you were quoted, it’s time to apply for an account.
When you sign up for a merchant account with an ISO, MSP, or direct processor, you fill out the application portion of the contract. This is often online, but many sales reps are happy to walk you through the application over the phone. You provide details about both your business and yourself, including your employer ID, Social Security number, and bank account information.
The processor then reviews your application and sets up your account. This usually takes up to two days; some processors can get it done the same day you apply, while others take up to a week. Your sales rep can help you decide what processing equipment you need and if any extra features – like gift cards and loyalty programs – are needed. Once your equipment arrives, the processor will help you set it up and test it to make sure it works properly, and ensure you know how to use it.
If you sign up with a payment facilitator instead, the process is very easy. You fill out an online form to create your account by entering some brief information about yourself and your business. Then, you can order processing equipment and download the app onto your phone or tablet.
Frequently asked questions about credit card processing
What is credit card processing?
Credit card processing is a series of actions that securely move money from a customer’s credit card account to your company’s bank account. It takes multiple parties to do this – credit card companies, banks and processors – and each of them takes a portion of the transaction fees you pay the processor in exchange for their services.
How does credit card processing help my business?
Credit card processing helps your business by offering your customers more payment options. With it, you can accept all major credit cards and debit cards. With a new credit card reader, your business can accept payments using contactless cards and mobile wallets, such as Apple Pay and Google Pay.
What are the benefits of credit card processing? Can’t I just accept cash?
You could just accept cash – and some businesses do – but you risk losing business from customers who prefer to pay with credit and debit cards. According to the Federal Reserve’s 2018 report on the Diary of Consumer Payment Choice, 30% of all transactions are paid in cash, 27% use debit cards, and 21% credit cards. Of course, these numbers shift depending on the dollar amount of the transaction, the type of business you have, and your customers’ age.
What is a merchant account? Do I need one?
ISO, MSPs, and direct processors can set you up with a merchant account and a merchant ID (MID). They then act as the liaison between your business and your customer’s credit card company or bank. They process payments and make sure the money is appropriately withdrawn from a credit card account. Once the money clears all of the processing protocols, it can be transferred to your company’s bank account.
Payment facilitators set you up as a submerchant under their merchant account. The pros of this arrangement are that it’s very easy to set up your account, the company takes care of PCI compliance, and there are usually no monthly or annual fees. The cons are that there are more restrictions on your account, the processor won’t work with certain business types and there are limits on how much you can process. If you process more than $100,000 a year, you’ll be required to get your own merchant account.
How does credit card processing work?
When your customer inserts a card into the credit card reader, the data on the card and a request for payment are securely transmitted between the processor, the credit card network, and the bank that issued the card. The bank that issued the card authorizes or denies the payment request, and the information is transmitted back through the credit card network, the processor, and the merchant bank. At the end of the day, the merchant batches its transactions and the data again travels through these channels to debit the customer’s credit card for the amount of the transaction and deposit the funds into your business bank account.
What are the best ways to use credit card processing?
The best way to use credit card processing is to accept payments across every channel your customers want to use – whether that’s in person at your physical business location, using a mobile device if you’re working offsite, or taking payments online through your website or electronic invoices. Depending on how your business works with customers, you may need to utilize multiple acceptance methods.
What kind of cost should you expect for credit card processing?
No matter which type of processor you work with, you’ll pay transaction fees for every card payment you accept. If you work with a full-service processor, you’ll also pay a variety of other fees.
What is the average fee for credit card processing? What kinds of fees come with credit card processing?
For each transaction, you’ll pay a percentage of the sale (usually 2% to 4%) and often a per-transaction fee (usually 10 to 30 cents). If you work with a payment facilitator, there usually aren’t any other fees. But if you want your own merchant account, you’ll have account service fees – such as a monthly fee, gateway fee, and an annual PCI compliance fee.
How much are credit card fees for merchants? For customers?
It depends on several factors, such as the types of cards your customers use and how you accept them, the processor you work with, and the model it uses to calculate your fees.
Most processors prefer to use the tiered pricing model to calculate your processing costs, but industry experts recommend the interchange-plus pricing model, as it’s more transparent. You’ll want to ask which pricing model the company uses when you call for a quote.
Customers don’t usually pay credit card fees directly. Most of the time, you can include this expense in the prices you charge customers. Although it’s legal in most states to add a surcharge when customers pay by credit card, or to set a minimum purchase requirement, it annoys customers.
What kind of equipment do you need for credit card processing?
The type of equipment you need depends on how you plan to accept cards. If you have a countertop checkout station in your brick-and-mortar location, you’ll need a credit card terminal. If you plan on using a POS system, check with that provider before choosing a processor to make sure you choose one that’s compatible. If you want a mobile credit card processing solution, you’ll need a credit card reader that either plugs into your phone or tablet or connects via Bluetooth.
