How to Accept Credit Cards

A Business News Daily Buyer's Guide

Product and service reviews are conducted independently by our editorial team, but we sometimes make money when you click on links. Learn more.

No matter what type of business you have, you need to be able to accept credit card payments from your customers. Sure, it's easier just to accept cash, but you also want to accept credit and debit cards, since so many people prefer to pay for things this way.

But to do this, you need to choose a service provider – which can be challenging, because there are hundreds of payment processing companies to choose from and several factors to consider before selecting a processor. To find the most convenient and least expensive route from your customer's credit card to your bank account, you want to look for credit card processing companies that have low rates, few fees and month-to-month contracts.

If your business is new or not yet accepting credit card payments, you're probably wondering, "How do you accept credit cards?" and "How much does it cost to accept credit cards?" These steps will walk you through the process of setting up credit card processing for your business. Scroll down or click on the links to learn more about each step.

Here's what you need to do to accept credit cards:

  1. 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?
  2. Identify how you plan on accepting credit cards and evaluate equipment options. Do you plan to accept credit cards online, at a countertop checkout station in a brick-and-mortar store, or do you prefer a mobile credit card processing solution that uses a smartphone and a card reader? Or do you want to accept payments multiple ways?
  3. 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.
  4. 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 what a good deal is for your specific 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.
  5. Read the contract before you choose a processor. Find out which terms are negotiable, where to find sneaky hidden fees and when you should look for a different option.
  6. 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.

If you're ready to choose a service provider, check out our credit card processor recommendations and reviews. If you plan to use a point-of-sale system to accept credit cards, we have POS system recommendations and reviews for those as well.

The first thing to consider is whether you need a service that works with individuals or if you can work with those that only serve businesses. The second thing you'll need to factor in is the average monthly volume of credit and debit card payments that you accept. Here are four use cases to help you find the right payment processing solution.

If you're an individual wanting 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. It's one of the few payment processors that works with both individuals and businesses, and all you pay is a small fee each time you accept a credit card payment – there are no monthly and annual fees. Square gives you a card swiper, or you can buy an inexpensive chip card reader from the company.

If you simply want to be able to accept credit card payments from friends, family or other people you know and trust – such as the friends you split the bill with at dinner last night – you can use PayPal or peer-to-peer payment services like Venmo, Apple Pay Cash, Google Pay Send or Zelle.

Tip: You don't want to use a P2P payment service to accept payments if you don't know and trust the individual, as buyers can reverse transactions.

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 PayPal, Square or Stripe. These are cheaper to use at this processing volume because you only pay 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, monthly fee (such as statement and payment gateway fees) or annual PCI compliance fee.

Payment facilitators, also called mobile credit card processors, are sometimes referred to as merchant aggregators, as they 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. You should carefully read the user agreement to make sure the goods or services you provide aren't prohibited. Also be aware that if there are irregularities with your processing, such as abnormally large transactions or a sudden spike in monthly volume, the processor may freeze your funds – which can be hard on your cash flow.

Tip: If you have small sales tickets, save money by choosing a credit card processing company that only charges 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.

If your small business processes more than $3,000 per month or has large sales tickets, you want to work with an ISO/MSP like Helcim, Flagship Merchant Services, Fattmerchant or Payline. These payment processing companies can set you up with a merchant account, and even though they charge fees that the aggregators don't, they have lower rates, which saves you money when you're processing at this volume or higher.

ISO/MSPs are independent sales organizations (ISO) and merchant service providers (MSP) that resell merchant accounts from direct processors. Because you're still processing a lower volume than big businesses, you're not likely to get better rates from direct processors. 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 charge a monthly minimum fee, which is the minimum dollar amount of credit card processing fees you must generate each month. If you don't generate enough in fees, you pay a fee to make up the difference. When you call for quotes, be sure to ask what the monthly minimum is and the dollar amount of sales you'll need to process each month to meet it.

If you process a high volume of sales each month, you could also consider working with a direct processor like First Data, Chase Merchant Services, Elavon, TSYS or Worldpay. These companies tend to be better suited to large businesses, but they work with small businesses as well.

Direct processors provide merchant accounts and have relationships with the banks and credit card brands. Again, you'll want to comparison shop for favorable rates, fees and contract.

If you plan to use a point-of-sale system, you want to 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 allow you to work with third-party payment processors so you can shop around for low rates and fees. 

You want to be able to accept credit card payments wherever and however your customers want to pay, whether that's in person at your business or another location, online through your website or electronic invoices (including both one-time and recurring payments), over the phone, or across multiple channels.

Once you decide how you'll accept credit cards, you need to think about what kind of credit card processing equipment you'll need. All card readers can accept magnetic stripe cards, but you want a model that can accept EMV chip cards as well, because it 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 that allows you to accept mobile wallets like Google Pay and Apple Pay so 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 them. 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 to check for compatibly.

You should plan to buy your credit card processing equipment upfront. Payment Depot explains in a blog post why you should never lease a credit card processing terminal. 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 also cautions against leasing credit card processing equipment.

Also be wary of "free" equipment, as you may be charged higher rates and additional fees (such as an "insurance fee" or some sort of equipment maintenance fee), and most companies require you to return the equipment when you close your account.

Here are some of your processing hardware and technology options.

This is a portable device that 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 are very affordable, usually costing less than $100.

Mobile card readers can be used as stand-alone devices or as part of a larger system. Though popular with small business owners who accept credit cards on the go or in the field, they're also useful for businesses that want to process transactions from anywhere in the store or those that only run a few transactions each day at a physical location.

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 you can accept chip cards, and most also have NFC technology so you can accept mobile payments. Credit card terminals usually cost $150 to $600.

Payment terminals are the most common type of processing equipment and are best for businesses that need a card reader to connect to or work alongside a POS system, or those that don't need the credit card processing system to do anything but accept payments. [See our related article: Credit Card Machines: Answers to Frequently Asked Questions]

This is a complete checkout station that typically includes software, a tablet or touchscreen, a card reader, a 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. Barcode scanners and other peripherals may also be added.

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 businesses with a physical location, particularly those that want to connect to other business software, such as accounting or inventory programs. [Check out our POS systems recommendations and reviews.]

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 also charge a gateway setup fee and another per-transaction fee.

Tip: If you already accept cards at a physical location, check with your processor before signing up with another service to take credit cards online, as some contracts have exclusivity clauses that prevent you from working with multiple payment processors.

Credit card processing fees are confusing, but you need to understand what they are and what they're for so you can negotiate the best transaction rates and avoid paying more than you have to for this type of service.

The three common types of credit card processing fees are as follows. Scroll down or click on the links to learn more about them.

  • 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 transaction. For clarity, we refer to these fees as rates. Processors have different methods of calculating and charging these rates – we refer to these 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 account maintenance fees, such as statement fees and PCI compliance fees. Some of these are standard fees, but others aren't charged by the best credit card processors.
  • Incidental fees: These are fees that you're charged for on a per-occurrence basis, and are triggered by certain actions on your account, such as chargebacks. Again, some of these are standard fees, but others aren't charged by the best credit card processing services.

Transaction rates are calculated differently, depending on the pricing models the processors use. 

The three most common pricing models are interchange-plus, tiered and flat-rate pricing. Here's how each option works, along with information on which pricing model is best for different business types and sizes.

Flat-rate pricing is usually charged by payment facilitators such as 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 mobile, you pay 2.7% of the transaction. This is the lowest rate, because this payment method has the lowest risk of fraud.
  • Card not present: 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 not present: 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, but it's lower than the keyed-in rate because it requires your customer to supply additional verification information (like your address and the CSV number on the back of the card).

Tip: There's usually no rate difference based on the type of card you accept, which is both a pro and a con, depending on the cards your customers favor. It's a benefit if you accept a lot of rewards credit cards or American Express cards, as you don't pay a higher rate. (Other processors charge more for these cards – around 3.5% isn't uncommon for a card-present transaction using a premium rewards card.) However, if most of your customers pay in person using PIN debit cards, you're paying more than you would with other pricing models.

Interchange-plus is the best option for most businesses. Industry experts recommend interchange-plus pricing because it's more transparent than the other pricing models, showing you 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 business bank account. There are hundreds of interchange rates, depending on the type of card and the brand. The card networks also charge small for each transaction. These rates are the same for every processor – regardless of whether they're a payment facilitator, ISO/MSP or direct processor – and they're non-negotiable. The only negotiable 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 receive, 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.

So, for this transaction example, the full rate would be 2.05% plus 20 cents.

Tip: The best processors offer this type of pricing to all their customers and post their rates online. But most of the time, you have to specifically ask for it, and there may be hoops you need to jump through to qualify for it, such as processing a certain volume of sales each month or processing with the company for a specified amount of time, such as six months to a year.

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, 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 merchants with an unhappy surprise when they get their first bill.
  • Transactions can be "downgraded" for various reasons, resulting in higher rates than those you were quoted. When you call for a quote, you'll want to ask which actions can cause a transaction to be downgraded.

Tip: When you call for a quote, you should 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 non-qualified. Some only have two, though, and there may also 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, it 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 include it with the monthly fee or charge it quarterly. For this fee, 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 non-compliance fee each month until you get 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 merchants 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. 

Some fees are only charged when certain actions have taken place. For instance, if a customer initiates a chargeback, you would need to pay a chargeback fee. If you use the processor's address verification service (AVS) or call its voice authorization center as 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 exactly what fees to expect.

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 services. 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, allowing you to evaluate how prompt, helpful and knowledgeable the rep you speak with is – which can be an important consideration as you're choosing a service provider, especially if the rep will be your account manager.

Tip: Never give a sales rep your bank account information or Social Security number until you're ready to sign up with that company. Likewise, never sign anything or provide any documents that carry your signature until you're ready to sign up with that company. (That "application" they want you to sign is actually part of the contract. If you sign it, you've signed up for an account.) If you look at online complaints for this industry, numerous merchants report being signed up for a credit card processing account without their consent, which is why you should take these precautions.

If you already know what you need and just want to see our recommendations for the best credit card processing services, visit our best picks page here.

No one wants to read the contract before signing up for a service, but with this industry, it's just something that you need to do. 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 ISO/MSPs and direct processors, these typically have three parts: the application, the terms of service and the program guide. Some applications have links to the other two documents in the fine print, but usually you'll need to ask the sales rep to send each of them to you separately.

  • Application: Usually this document includes credit card processing rates and some fees. It asks for your bank information, Social Security number and signature – again, don't fill out this 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 and waivers have been noted. 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 also lets it perform credit checks on you.
  • Terms and conditions: This document describes the length of the term and additional fees that you 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 for "Additional Services." You'll note that it doesn't explain exactly what these additional services are or what they cost, but does note 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 upfront, and if you don't ask for it, it will be tucked in with the processing hardware you order – which is a little late, since by that time, you've already signed up for the processing service. 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 that costs 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 (ETF)," "early deconversion fees (EDF)," "exit fees" or "lost profit fees."

Tip: If the processor you want to work with has a lengthy contract, ask your sales rep if month-to-month terms are available and if they can waive the early termination fee and any liquidated damages. Most companies want your business and are willing to give you more favorable terms.

Most payment facilitators have user agreements instead of contracts. These are much shorter, but still important to read. You want to check the list of prohibited goods and services to make sure the processor will work with your business. You also want to read the 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.

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 and any waivers are noted, 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 the 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, but 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 as well as any extra features, like gift cards and loyalty programs. Once your equipment arrives, the processor will help you set it up and test it to make sure it works properly and 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, entering some brief information about your business and yourself. Then, you can order processing equipment and download the app onto your phone or tablet.

Credit card processing is a series of actions that securely moves money from a customer's credit card account to a merchant'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.

Credit card processing helps businesses give their customers more payment options. With it, you can accept all major credit cards – Visa, Mastercard, Discover and American Express – as well as debit cards. With a new credit card reader, your business can also accept payments made using contactless cards and mobile wallets like Apple Pay and Google Pay.

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% are paid using debit cards, and 21% are paid using credit cards. Of course, these numbers shift depending on the dollar amount of the transaction, the type of business you have and the average age of your customers.

Both ISO/MSPs and direct processors can set you up with a merchant account and a merchant ID (MID). They then act as middlemen 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 business bank account. [See our pick for best credit card processor for small business here.]

Payment facilitators set you up as a sub-merchant 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.

When your customer inserts a card into the credit card reader, the data on the card and a request for payment is 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 their 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.

The best way to use credit card processing is to accept payments across every channel your customers want to use to pay you, 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 use multiple acceptance methods.

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. See step three above for more information about pricing.

For each transaction, you'll pay a percentage of the sale (usually 2% to 4%) and often a per-transaction fee as well (usually 10-30 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.

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, merchants include this expense in the prices they charge their customers. Although it's legal in most states for merchants to add a surcharge when customers pay by credit card or to set a minimum purchase requirement, most merchants don't, as there are certain rules you must follow – and it annoys customers.

The type of equipment you need depends on how you plan to accept cards. If you have a brick-and-mortar location and a countertop checkout station, you'll need a credit card terminal. If you plan on using a POS system, you'll 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. See step two above for more information on credit card processing hardware.
