How Small Businesses Choose and Set Up Payment Methods

What payment methods your customers expect, and why it matters

Your customers will pay you in whatever way is easiest for them—not what is easiest for you. That means you need to accept at least card payments (debit and credit), and probably a digital wallet like Apple Pay or Google Pay. Cash is still used, but fewer customers carry it. Bank transfers and checks are slower and require more work on your end. The payment methods you choose affect how fast you get paid, how much you pay in fees, and whether customers buy from you at all.

The core decision is not whether to accept cards—you almost certainly have to—but which processor handles them, what you pay per transaction, and what other methods you bundle in. A restaurant might prioritize speed and low fees on small transactions. A contractor might need invoicing and bank transfer options. A retail shop might need a physical card reader plus online checkout. The right setup depends on how your customers actually pay you.

Key Takeaways

• Card processing (debit and credit) is now the baseline expectation; most small businesses need a merchant account or a payment processor to accept them.
• You pay a percentage of each transaction (typically 2 to 3 percent) plus sometimes a per-transaction fee, and these costs vary widely between processors.
• Digital wallets (Apple Pay, Google Pay, PayPal) and bank transfers are faster for customers but may cost you more or require extra setup.
• Your payment processor handles the technical side, but you remain responsible for security, refunds, and disputes with customers.
• Choosing a processor involves comparing fee structures, the types of transactions you run most, and whether you need invoicing, recurring billing, or reporting tools.

Card processing: how fees work and what you actually pay

When a customer swipes, taps, or enters a card, three parties take a cut: the card network (Visa, Mastercard, Discover, American Express), the customer's bank, and your processor. Together, these are called the interchange fee and the processor markup. You see one number on your statement, but it is really multiple fees bundled together.

Interchange rates are set by the card networks and vary by card type (a rewards credit card costs more than a debit card) and how the transaction happens (a card present in your hand costs less than a card number typed online). Your processor then adds its own markup on top. A typical total is 2.2 to 2.9 percent for in-person debit cards, and 2.9 to 3.5 percent for credit cards. Online transactions often run higher. Some processors also charge a flat fee per transaction—$0.30 is common—on top of the percentage.

The fee structure matters because it changes what you actually pay. A processor advertising "2.9 percent" might charge 2.9 percent plus $0.30 per transaction, or might include the per-transaction fee in that 2.9 percent. A processor using interchange-plus pricing shows you the actual interchange rate plus their markup separately, which is more transparent but sometimes higher overall. Before you sign up, ask for a sample statement or run a test transaction to see the real cost.

In-person payments: card readers, terminals, and point-of-sale systems

If you take payments face-to-face, you need a way to read the card. The simplest option is a small wireless reader (like Square, Toast, or Clover) that plugs into your phone or tablet. These cost $50 to $300 upfront and work anywhere with cell service or WiFi. They are fast to set up and good for small businesses, pop-ups, or service calls. The trade-off is that fees are usually higher than a traditional merchant account, and you are locked into that processor's ecosystem.

A traditional point-of-sale terminal (a standalone device that sits on your counter) is more expensive upfront—$500 to $2,000—but often has lower per-transaction fees if you process high volume. These systems also usually include inventory tracking, employee management, and detailed reporting. They work best for retail shops, restaurants, and service businesses that run dozens of transactions a day.

A full point-of-sale system (hardware plus software) can cost $1,500 to $5,000 to set up, plus monthly software fees of $50 to $300. You get everything: payment processing, inventory, customer data, employee timecards, and reporting. This makes sense if you have multiple locations or need to track stock and staff. For a solo business or startup, a phone-based reader is usually the right starting point.

Online and remote payments: checkout pages, invoices, and links

If you sell online or send invoices, you need a way to take payment without the customer being in front of you. The most common options are a payment link (you send a unique URL, customer clicks and pays), an embedded checkout (payment form on your own website), or an invoice with a pay button (customer receives an invoice and clicks to pay).

Payment links are the simplest: you generate one in your processor's dashboard, send it via email or text, and the customer pays. No website needed. Fees are the same as in-person (or slightly higher), and the money lands in your account in 1 to 3 business days. Processors like Stripe, Square, and PayPal all offer this.

An embedded checkout means the payment form lives on your website, so customers never leave your site. This looks more professional and has slightly lower fees in some cases, but requires more technical setup. You need a website first, and you may need a developer to integrate the payment form. Stripe and Shopify are common choices here.

Invoicing with a pay button is useful if you bill customers regularly or after work is done. You create an invoice in your processor's system (or accounting software), it includes a "Pay Now" button, and the customer clicks to pay. This works well for contractors, consultants, and service businesses. Some processors charge extra for invoicing features; others include it.

Digital wallets and alternative payment methods

Apple Pay, Google Pay, and PayPal are now expected by many customers, especially younger ones. These are not separate payment methods you need to set up—they are tokenized card payments. When a customer uses Apple Pay, they are really sending their card information securely to your processor. You do not need a separate account or approval; if your processor accepts cards, it accepts digital wallets.

Bank transfers (ACH in the United States) are slower but cheaper. A customer authorizes you to pull money from their bank account, and it takes 3 to 5 business days. Your fees are lower—often $0.25 to $1.00 per transaction instead of 2 to 3 percent—but the delay means this works better for invoices than for immediate sales. Some processors charge extra to offer ACH; others include it.

Buy now, pay later services (Affirm, Klarna, Afterpay) let customers split a purchase into installments. You get paid immediately, but you pay a higher fee (4 to 8 percent). These are useful if you sell higher-ticket items and want to remove price barriers, but they are not necessary for most small businesses.

Choosing a processor: what to compare and what questions to ask

Start by listing how you actually take payments. Do you run mostly in-person transactions? Invoices? Online orders? A mix? Then compare processors on three things: fee structure (what you pay per transaction), features (do you need invoicing, recurring billing, inventory tracking?), and support (can you reach someone by phone if something breaks?).

For fee structure, get a written quote or sample statement from at least two processors. Do not rely on their website; ask them to show you what a $100 transaction costs, a $1,000 transaction, and a refund. Ask whether they charge monthly minimums, setup fees, or early termination fees. Ask what happens if you process less than expected in a month.

For features, make a list of what you actually need right now, not what you might need someday. Do you need invoicing? Recurring billing? Employee access? Detailed reporting? Inventory tracking? Some processors bundle these in; others charge extra. Starting simple is fine—you can add features later.

For support, call their customer service line and see how long you wait and whether a human answers. Read recent reviews on independent sites (not their own website). Ask existing customers if you can. A processor with slightly higher fees but reliable support is usually worth it.

Security, disputes, and your responsibilities

Your processor handles the technical security of the payment, but you are responsible for protecting customer data and following the rules. If you store card information, you must comply with PCI DSS (Payment Card Industry Data Security Standard), which means your systems must meet certain security standards. Most small businesses avoid this by not storing card data themselves—they let the processor handle it.

When a customer disputes a charge (calls their bank and says they did not authorize it or the product was not as described), the processor investigates and either sides with you or refunds the customer. You can fight back with evidence—a signed receipt, an email confirmation, proof of delivery—but the burden is on you. Keep records of every transaction for at least a year.

Refunds are your responsibility. If a customer returns something or you make a mistake, you process the refund through your processor. It takes 3 to 5 business days to reach their account. Some processors charge a small fee to process a refund; most do not.

Frequently Asked Questions

Do I have to accept credit cards?

No law requires it, but practically speaking, yes. Most customers expect it, and refusing cards will cost you sales. The fees are real, but they are a cost of doing business, like rent or utilities. Budget 2 to 3 percent of your revenue for payment processing.

What is the difference between a merchant account and a payment processor?

A merchant account is a bank account that holds the money from card sales before it moves to your regular business account. A payment processor is the company that handles the technical side—reading the card, checking with the bank, moving the money. Many companies now do both, so the distinction is blurry. What matters is what you pay and how fast you get the money.

How long does it take to get paid after a customer pays?

Usually 1 to 3 business days, depending on your processor and your bank. Some processors offer next-day deposits for a higher fee. Weekend and holiday deposits may take longer. Ask your processor for their standard timeline before you sign up.

Can I use the same processor for in-person and online payments?

Yes, most processors handle both. You may pay different fees for each (in-person is usually cheaper), but you use the same account and the money goes to the same place. This simplifies accounting and reporting.

What happens if my processor goes out of business?

Your money in the merchant account is yours and will be transferred to your bank account or a new processor. Your customer data and transaction history may or may not transfer, depending on the processor. This is rare, but it is worth asking a new processor what their backup plan is.
