The fastest way to accept credit card payments is to open a free account with a payment aggregator like Square, Stripe, or PayPal, link a bank account, and either plug in a small card reader or send the buyer a payment link. Setup takes minutes and doesn’t require a storefront or business license. Every sale carries a fee, usually 2.3% to 2.7% plus a few cents when the card is physically present, and 2.9% to 3.5% plus roughly $0.30 when it’s keyed in or paid online.
Pick the Right Tool for How You Sell
Peer-to-Peer Apps for Occasional Sales
Selling a used couch or collecting money from friends is what apps like Venmo and Cash App are built for. The buyer can fund the payment with a credit card, and the cost lands on them: Venmo charges the sender 3% for credit-card-funded payments.1Venmo. About Venmo Fees The terms of service on personal accounts generally prohibit ongoing commercial use, so if you’re regularly selling anything, this isn’t the right lane.
Payment Aggregators for Most Small Sellers
Square, Stripe, and PayPal bundle thousands of small sellers under a single merchant relationship with the card networks. You skip underwriting, sign up online, link a bank account, and start accepting cards the same day. There’s usually no monthly fee; the processor takes a percentage plus a flat fee on each transaction.
These platforms give you options that match how you actually sell: tap-to-pay through your phone, a small plug-in reader for in-person sales, invoices by email, and payment links you can text. They handle security, batch your deposits, and show your sales on a dashboard. For anyone running less than roughly $10,000 a month through cards, the simplicity is worth more than any rate you’d negotiate elsewhere.
Merchant Accounts for Higher Volume
A dedicated merchant account is a direct relationship between your business and an acquiring bank. The bank underwrites you individually, which means a credit check, financial documentation, and sometimes a wait for approval. In return you can often negotiate lower per-transaction rates than an aggregator charges. The tradeoff is monthly fees and more administrative overhead. It starts making sense when card volume consistently clears several thousand dollars a month and the per-sale savings outweigh the fixed costs.
A Note on Restricted Businesses
Not every product can go through a standard aggregator. Cannabis, adult content, gambling, cryptocurrency sales, and some travel services sit on the restricted lists most processors publish, and running a prohibited transaction can freeze your funds without warning.2Stripe: Help & Support. Prohibited and Restricted Businesses List — FAQs If your product is in a gray area, read the acceptable use policy before your first sale.
What You Need to Sign Up
Every processor will ask for a taxpayer identification number before activating your account. That’s your Social Security Number if you’re operating as an individual, or an Employer Identification Number if you’ve set up a business entity. Federal law requires payment processors to report your gross payment volume to the IRS, and they need the tax ID to do it.3Office of the Law Revision Counsel. 26 U.S. Code 6050W – Returns Relating to Payments Made in Settlement of Payment Card and Third Party Network Transactions
You’ll also link a checking or savings account using its routing and account numbers. That’s where settled funds land, usually at the end of each business day. Expect the platform to verify your identity with your address, date of birth, and a short description of what you sell.
For hardware, many sellers start with nothing but their phone. Square and PayPal ship free basic readers, and newer phones support tap-to-pay directly through the processor’s app. A dedicated chip reader runs $30 to $60 if you take in-person payments often. Online-only sellers need no hardware at all; invoices and payment links do the work.
What Each Sale Actually Costs
Processing fees have two parts that matter to you. Interchange goes to the bank that issued the buyer’s card and is set by the card networks, not by Square or Stripe. For credit cards, interchange generally runs between 1.5% and 2.6% of the sale, and recent rates have trended toward the high end.4Mastercard. Mastercard 2025-2026 US Region Interchange Programs and Rates The processor’s markup covers fraud prevention, handling, and deposits. Aggregators combine the two into one flat rate, so you see a single number.
Typical all-in rates in 2026:
- In-person, card present: about 2.3% to 2.7% of the sale, plus $0.05 to $0.15 per transaction
- Online or manually keyed: about 2.9% to 3.5%, plus $0.30 to $0.49 per transaction
Online rates run higher because the card isn’t physically present, which raises fraud risk. Keying in a card number during an in-person sale puts you at the online rate.
In dollars, a $100 in-person charge costs about $2.75 in fees. The same $100 charged online runs closer to $3.20 to $3.99. At $1,000 in monthly sales, you’re giving up roughly $27 to $40. Fees are deducted automatically before the money hits your bank, so your deposit is always less than what the buyer paid.
How the Money Moves
When the buyer taps, dips, or swipes, the processor sends an authorization request through the card network to the card’s issuing bank. The bank checks for funds and either approves or declines. The whole exchange takes a few seconds. An approved authorization doesn’t mean the money is in your account yet; the funds sit pending while the processor batches the day’s transactions and submits them for settlement. Settlement typically completes within one to three business days, at which point money moves into your linked bank account.
Void a Charge Before Settlement, Refund After
If you need to cancel a sale before the day’s batch processes, void it. A void cancels the charge before settlement, no money moves, and you generally pay no processing fee. Once the batch has settled, voiding is off the table and you have to issue a refund instead. Refunds reverse the transfer after the fact and return the money to the buyer’s card, but most processors keep their fee on a refund because the original sale already ran through their system. When you have the choice, void.
Passing Fees to the Buyer
Some sellers add a surcharge on credit card sales to offset the fee. The card networks allow it within limits. Visa caps surcharges at 3% of the transaction; Mastercard caps them at 4%.5Mastercard. What Merchant Surcharge Rules Mean to You In both cases the surcharge can’t exceed your actual cost of acceptance, so it can’t become a profit center. You have to notify the card network and your acquiring bank at least 30 days before starting, and the surcharge must be disclosed at the point of sale and printed on the receipt.
Roughly a dozen states restrict or prohibit credit card surcharges, so this isn’t universally available. Even where it’s legal, surcharges can push buyers toward cash or away from the sale. Many sellers find it less friction to build the fee into their pricing.
Chargebacks Are the Expensive Risk
A chargeback happens when a buyer contacts their card issuer to dispute a charge, and the issuer reverses it without your consent. The money is pulled from your account, and the processor adds a dispute fee on top of the lost sale. Those fees commonly range from $20 to $100 per dispute whether you win or lose.
You can fight a chargeback by submitting evidence that the transaction was legitimate. The clock starts when your acquiring bank notifies you, and you generally have 20 to 45 days to respond with documentation.6Mastercard. How Can Merchants Dispute Credit Card Chargebacks Miss the deadline and you lose by default. The full process can take up to 120 days to resolve.
Winning comes down to evidence. For card-present sales, a signed receipt or chip-read confirmation often suffices. For online sales, Visa’s Compelling Evidence 3.0 framework looks for data linking the disputed transaction to the buyer’s prior legitimate purchases.7Visa. Compelling Evidence 3.0 Merchant Readiness Save everything: delivery confirmations, email correspondence, signed contracts, screenshots of completed work. It’s your defense if a buyer later claims they never authorized the charge.
Taxes and the 1099-K
Payment processors report your gross payment volume to the IRS on Form 1099-K. The current reporting threshold, reinstated retroactively by the One, Big, Beautiful Bill, is $20,000 in gross payments and more than 200 transactions in a calendar year for third-party network transactions.8Internal Revenue Service. IRS Issues FAQs on Form 1099-K Threshold Under the One, Big, Beautiful Bill Both conditions must be met. Payment card transactions (where a buyer uses a credit or debit card) have no minimum threshold and are reported regardless of amount.9Internal Revenue Service. Publication 1099 General Instructions for Certain Information Returns (Draft for 2026)
Receiving a 1099-K doesn’t mean you owe tax on the full amount. Personal items sold at a loss and reimbursements aren’t taxable income, but the IRS sees the form and expects your return to account for it. Processing fees are deductible as a business expense if you’re accepting cards as part of a trade or business.10Internal Revenue Service. Pay Your Taxes by Debit or Credit Card or Digital Wallet Keep records of what your processor withholds so you can claim the deduction.
Keeping Card Data Safe
If you accept credit cards, you’re responsible for protecting cardholder data under the Payment Card Industry Data Security Standard (PCI DSS). All merchants are expected to comply regardless of size, and non-compliance fines start at $5,000 to $10,000 per month. Most small sellers using an aggregator are shielded from the heaviest compliance burden because the aggregator handles card data on their behalf. Your obligations are lighter, but they exist.
The core rule is simple: don’t store card data you don’t need. Never write down a full card number, email card details, or keep unencrypted payment information on your phone or computer. When you use a processor’s app or reader, the data flows through their encrypted systems and never touches yours. Smaller merchants typically self-certify by completing a short questionnaire through their processor. If you’re asked to fill it out, do it. That questionnaire is your proof of compliance if something goes wrong.
