How Businesses Accept Payments: Methods, Costs, and What Happens Behind the Scenes

What payment methods your business can accept, and what each one costs you

When a customer hands you cash, swipes a card, or sends money through their phone, different things happen on the back end—and you pay different amounts for each one. Cash costs you nothing to accept but requires you to handle, count, deposit, and secure it. Credit and debit cards cost you a percentage of each sale (usually 1.5% to 3.5%) plus sometimes a flat fee per transaction, but the money lands in your account within one to three business days. Digital wallets like Apple Pay and Google Pay use the same card networks underneath, so they cost the same as card payments. Bank transfers (ACH) and checks are cheaper or free but slower—ACH takes three to five business days, and checks can take a week or more.

The method you choose affects how fast you get paid, how much you keep, and what fraud risk you carry. A coffee shop might accept only cash and cards. A contractor might ask for bank transfer to avoid card fees on large invoices. An online store might offer everything. There is no single right answer—it depends on your customers, your margins, and how much cash flow matters to you.

Key Takeaways

• Cash is free to accept but requires you to physically handle, secure, and deposit it; card payments cost 1.5% to 3.5% per transaction but arrive in your account within days.
• Credit cards, debit cards, and digital wallets all run through the same card networks and cost you roughly the same percentage, though the exact rate depends on your processor and your industry.
• Bank transfers (ACH) and checks are cheaper than cards but take longer—three to five days for ACH, a week or more for checks—and require the customer to initiate the payment.
• Your payment processor (the company that handles the transaction) sets the fee structure, so shopping around and negotiating rates can lower your costs significantly.
• Each payment method carries different fraud and chargeback risks; cards offer buyer protection that can work against you, while cash and bank transfers shift more risk to the customer.

How card payments work and why they cost what they do

When a customer swipes, taps, or enters a card number, the transaction moves through four separate companies before the money reaches your account. The customer's bank (the issuer) approves the charge. The card network (Visa, Mastercard, American Express, or Discover) routes the message and sets the rules. Your bank (the acquirer) receives the money on your behalf. And your payment processor—the company you signed up with—handles the software and takes a cut.

That cut is split three ways. The interchange fee (usually 1% to 2%) goes to the customer's bank. The assessment fee (usually 0.1% to 0.3%) goes to the card network. The processor markup (usually 0.5% to 1.5%) goes to your processor. On a $100 card sale, you might pay $2 to $3.50 total. Some processors also charge a flat fee per transaction (25 to 50 cents) on top of the percentage.

The exact rate depends on your industry, your sales volume, your average transaction size, and the type of card used. A grocery store pays less than a restaurant, which pays less than a gas station. A business processing $500,000 per month negotiates better rates than one processing $5,000. A debit card costs less than a credit card. Rewards cards cost more because the issuer pays out cash back or points. If you process a lot of transactions, it is worth calling three or four processors and asking for their rates in writing before you sign.

Digital wallets, mobile payments, and what they mean for your costs

When a customer uses Apple Pay, Google Pay, Samsung Pay, or a similar digital wallet, they are still using a credit or debit card underneath—the wallet just stores the card number and handles the tap or scan. From your perspective, the transaction looks and costs exactly like a regular card payment. You pay the same percentage and flat fees. The money arrives on the same timeline. The only difference is that the customer does not have to pull out a physical card.

Some businesses see higher sales when they accept digital wallets because the checkout is faster and feels more secure to the customer. Others see no difference. The cost to you is identical, so there is no reason not to accept them if your payment processor supports them—which most do now. A few processors charge slightly more for contactless payments, but this is rare and usually not worth paying.

Buy now, pay later services (Affirm, Klarna, Afterpay) are different. These are not wallets—they are loans. The customer borrows from the service, and you get paid immediately by the service, not by the customer. You pay a percentage fee (usually 2% to 8%) similar to a card, but the service handles the risk if the customer does not pay back the loan. These services are most common in online retail and are worth offering if your average order is large enough that the fee does not eat your margin.

Bank transfers, checks, and why they take longer

ACH transfers (Automated Clearing House) move money directly from one bank account to another. The customer initiates the transfer from their bank, and the money arrives in your account in three to five business days. You pay nothing, or sometimes a small flat fee ($0.25 to $1) if your processor handles it. The customer pays nothing either, though some banks charge their own customers for outgoing transfers.

ACH is common for business-to-business payments, subscription billing, and payroll. It is slower than cards but much cheaper, especially on large amounts. A contractor might ask a client to pay by ACH instead of card to avoid paying $300 in card fees on a $10,000 invoice. The tradeoff is that the customer has to remember to send the money, and you have to wait five days.

Checks work the same way but slower. The customer writes a check, you deposit it, and the money clears in five to ten business days depending on the bank and the amount. Checks are now rare in most industries but still common in construction, real estate, and some service businesses. They cost you nothing to accept but require you to physically deposit them, and there is a small risk the check bounces.

Both ACH and checks shift the burden to the customer—they have to remember to pay you, and they have to initiate the payment. This is fine if you have a long-standing relationship with the customer or if the payment is large enough that they will not forget. For retail or one-time sales, card payments are better because the customer pays immediately and you do not have to chase them.

Cash: the cost you do not see

Cash is free to accept in the sense that no processor takes a cut. But it has hidden costs. You have to count it, secure it (safe, lock, or armored car), deposit it at the bank, and reconcile it against your records. If you are robbed or if money goes missing, that is your loss. If you deposit it late, you do not get paid until the deposit clears. If you deposit a large amount, the bank may flag it for reporting purposes.

For a small retail business, these costs are usually worth it because most customers expect to pay cash and you avoid card fees. For a business that processes large amounts of cash, the costs add up—you may need to hire someone to count and deposit it, rent a safe, or pay for armored car service. Many businesses now discourage cash by offering discounts for card payments or by simply not accepting it.

One more thing: if you accept cash, you are responsible for reporting it to the IRS. Large cash deposits (over $10,000) trigger a Currency Transaction Report, which is routine and not a problem if your income is legitimate. But you still have to file it, and the IRS expects your reported income to match your deposits.

Chargebacks, fraud, and who pays when something goes wrong

A chargeback happens when a customer disputes a card charge with their bank and the bank reverses the payment. The customer gets their money back, and you lose the money plus a chargeback fee (usually $15 to $100). Chargebacks are common when a customer claims they did not authorize the charge, did not receive the product, or received something different from what they ordered.

Card networks offer buyer protection, which is good for customers but can hurt you. If a customer claims they never got their order, the card network often sides with them and reverses the charge, even if you have proof you shipped it. This is why many online businesses require signature confirmation on delivery and keep detailed records of what was ordered and when it shipped.

ACH transfers and checks do not have the same chargeback protection. If a customer disputes an ACH transfer, the process is slower and the bank is less likely to reverse it without strong evidence. This makes ACH safer for you but riskier for the customer, which is why customers are more cautious about sending ACH payments to unfamiliar businesses.

Fraud (a criminal using a stolen card) is handled differently. If a stolen card is used on your account, the card network investigates. If fraud is confirmed, the charge is reversed and you lose the money. You are not liable if you followed the card network's rules (checking the CVV, matching the address, etc.), but you still lose the sale. This is why some businesses ask for extra verification on large or unusual orders.

Choosing a payment processor and negotiating rates

Your payment processor is the company you sign a contract with to accept payments. Common processors include Square, Stripe, PayPal, Toast, and Clover. Each one charges different rates, has different features, and serves different types of businesses. A retail store might use Square or Clover because they offer point-of-sale hardware. An online store might use Stripe because it integrates with shopping carts. A restaurant might use Toast because it handles both payments and orders.

Before you sign up, ask each processor for their rate sheet in writing. The rate sheet should show the percentage fee, any flat per-transaction fees, monthly minimums (if any), and fees for chargebacks, refunds, and other services. Do not rely on their website—rates vary by industry and by individual negotiation. If you process a significant amount of money, call and ask to speak to a sales representative. They have room to negotiate, especially if you are switching from another processor.

Watch out for hidden fees. Some processors charge extra for things like batch fees (a fee to close out your day), gateway fees (a fee to connect to their system), PCI compliance fees (a fee for security certification), or early termination fees (a penalty if you cancel before your contract ends). Read the contract carefully, or ask an accountant to review it before you sign.

Frequently Asked Questions

Why do I pay more for credit cards than debit cards?

Credit card issuers pay out rewards (cash back, points, travel miles) to their customers, and they recover that cost by charging merchants higher interchange fees. Debit cards do not offer rewards, so the fees are lower. The difference is usually 0.5% to 1%, which adds up on high-volume businesses.

Can I refuse to accept certain payment methods?

Yes. You can accept only cash, only cards, only ACH, or any combination you choose. There is no law requiring you to accept a specific payment method. Some businesses refuse cards to avoid fees, and some refuse cash to reduce theft and handling. The only exception is if you receive government contracts or subsidies—those often require you to accept certain methods.

What happens if a customer's card is declined?

The transaction stops and no money changes hands. The customer's bank declined it, usually because of insufficient funds, a fraud block, or an expired card. You can ask the customer to try a different card or payment method. You do not pay a fee for a declined transaction, though some processors charge a small fee if declines happen frequently.

Do I have to accept digital wallets if I accept cards?

No. You can accept Visa and Mastercard but not Apple Pay, for example. In practice, most payment processors bundle digital wallets with card acceptance at no extra cost, so there is no reason to refuse them. But you are not required to.

How much should I charge customers to use a payment method?

You can pass card fees to customers in some states and industries, but not all. Some states prohibit surcharges on credit cards. Some card networks prohibit it in their contracts. The safest approach is to absorb the cost and build it into your prices. If you do pass fees to customers, disclose them clearly before they pay, and make sure it is legal in your state and complies with your processor's contract.
