What Square Credit Card Processing Actually Is
Square is a payment processor that lets you accept credit and debit cards in person, online, or by phone. You don't get a credit card from Square — instead, Square handles the transaction when a customer swipes, taps, or enters their card details. Square takes a small cut of each sale and deposits the rest into your bank account, usually within one to two business days.
The service is designed for small businesses, freelancers, and anyone else who needs to take card payments without a traditional merchant account. You can start with just a phone or tablet and Square's free app. The hardware — a card reader that plugs into your device — costs money upfront, but the software itself is free to read.
Key Takeaways
- Square charges a percentage of each transaction (called a rate) plus a small flat fee per swipe, with rates varying by card type and how the payment is processed.
- You need a business bank account and a device (phone or tablet) to use Square, and you'll receive payouts to that account on a set schedule.
- Square's hardware — the card reader — costs between $10 and $50 depending on which model you choose, and some readers are free with certain plans.
- Transactions appear in your Square account in real time, and you can track sales, refunds, and payouts through the same dashboard.
- Square also offers invoicing, online store creation, and point-of-sale features, so you can grow beyond card processing as your business does.
How Much Square Charges Per Transaction
Square's pricing depends on how the card is processed. For in-person payments where the customer's card is physically present, Square charges 2.6% plus 10 cents per transaction. If you key in the card number manually (called a card-not-present transaction), the rate is 3.6% plus 10 cents. Online payments through Square's checkout tool also run 2.9% plus 30 cents.
These rates explore to most standard credit and debit cards. Some premium cards (like American Express or certain rewards cards) may have slightly higher rates, but Square publishes its full rate card on its website so you can see the exact cost for each card type before you sign up. There are no monthly fees, no setup fees, and no hidden charges — you only pay when you process a transaction.
If you want a flat monthly fee instead of per-transaction rates, Square offers a subscription plan called Square Plus for $99 per month, which includes lower rates on in-person transactions (2.2% plus 10 cents) and some additional features like advanced reporting. The math works out in your favor only if you process more than about $8,000 in cards per month, so calculate your own volume before switching.
What Hardware You Need and What It Costs
Square's most popular reader is the Square Reader for contactless and chip, which costs $29 and works with any phone or tablet. It reads chip cards, tap payments, and mobile wallets like Apple Pay. If you want to accept magnetic stripe cards (older cards with just a stripe), you need the Square Reader for magstripe, which costs $10. Many newer cards don't use magstripe, so this is less common now.
For a full point-of-sale system — a standalone device that doesn't need a phone or tablet — Square offers the Square Terminal, which costs $399 upfront. It's a dedicated device with a built-in card reader, receipt printer, and screen. You pay the same per-transaction rates as with the mobile readers, so the extra cost is purely for the hardware and convenience of a standalone system.
Some of Square's subscription plans include a free reader, so if you sign up for Square Plus, you get a contactless reader at no extra charge. Check the current promotion when you sign up, because Square sometimes offers free hardware to new customers.
How Payouts Work and When You Get Your Money
When a customer pays you with a card, Square deposits the money into your business bank account on a schedule you choose during setup. Most accounts receive payouts once per business day, usually by 9 a.m. the next day. Some newer accounts or those with higher risk profiles may have a longer hold period — up to seven days — but Square will tell you your payout schedule before you process your first transaction.
You can see the full breakdown of each transaction in your Square Dashboard: the sale amount, the fee Square took, and the net amount you received. Refunds appear there too, and if you refund a customer, the money comes out of your next payout. Square doesn't charge an extra fee to process a refund — it just reverses the original transaction.
If you need access to your money faster, Square offers when ready Transfer, which moves funds to your bank account within minutes instead of waiting for the next scheduled payout. when ready Transfer costs 1% of the amount transferred (with a 25-cent minimum), so it's useful for emergencies but not something you'd use for every transaction.
Setting Up Your Square Account
You'll need a business bank account, a phone number, and a valid government ID to create a Square account. The signup process takes about 10 minutes on Square's website or through the mobile app. Square asks for basic business information — your name, address, and what you sell — and then verifies your identity.
Once your account is approved, you can read the Square app, pair it with a card reader, and start processing payments when ready. There's no waiting period or approval process for transactions; you can take your first payment the same day you sign up. Square does monitor accounts for fraud, so if you see unusual activity, Square may freeze your account temporarily while it investigates, but this is rare for legitimate businesses.
If you already have a Square account for one business, you can create additional accounts for other businesses or locations. Each account has its own bank account connection and its own transaction history, so you can keep your finances separate.
What Square Doesn't Do (And What You Might Need Instead)
Square processes card payments, but it doesn't provide a business loan, a line of credit, or any form of financing. If you're looking to borrow money to grow your business, you'd need to look at a separate lender — though Square does offer a cash advance product called Square Loans that you can explore separately.
Square also doesn't handle invoicing or accounting on its own, though it integrates with accounting software like QuickBooks. If you need to send invoices to customers who pay you later (not by card), you can use Square Invoices, which is included free with your account. For full bookkeeping, you'd connect Square to your accounting software so transactions sync automatically.
If you need to accept payments in person but don't have a smartphone or tablet, the Square Terminal is your option. If you need to accept payments by mail or check, Square doesn't handle that — you'd deposit checks at your bank the traditional way.
Comparing Square to Other Payment Processors
Square's main competitors are Stripe, PayPal, Toast, and Clover. Stripe charges similar rates (2.9% plus 30 cents for online, 2.7% plus 5 cents for in-person) but doesn't offer in-person hardware as easily — you have to buy a reader separately. PayPal's in-person rates are similar to Square's, but PayPal's online checkout is more expensive at 3.49% plus 49 cents. Toast and Clover are designed more for restaurants and retail, with higher upfront costs but more specialized features.
The real difference between these services is usually the ecosystem. Square is strongest if you want one tool that handles in-person payments, online checkout, invoicing, and a basic online store. If you only need online payments or only need in-person payments, a simpler processor might save you money. If you run a restaurant or retail store with complex inventory needs, Toast or Clover might fit better even though they cost more.
Frequently Asked Questions
Can I use Square if I don't have a business license?
Yes. Square doesn't require a business license to sign up, though you do need a valid ID and a business bank account. Many freelancers and sole proprietors use Square without formal business registration. If you operate under a business name, you may want to register it with your state, but that's a separate step from opening a Square account.
What happens if a customer disputes a charge?
The customer's bank investigates the dispute, and Square notifies you. You can respond with proof of the transaction (a receipt, email confirmation, or shipping tracking). If the bank sides with the customer, the money is reversed from your account. Square doesn't charge you a dispute fee, but you do lose the sale and the processing fee you already paid.
Can I use Square for online payments only?
Yes. You don't need a card reader to use Square Checkout on your website. You can create a free online store, send payment links to customers, or embed a checkout form on your site. You'll pay the online rate (2.9% plus 30 cents) instead of the in-person rate, but you won't need any hardware.
Does Square report my sales to the IRS?
Yes. Square reports your card transaction volume to the IRS on Form 1099-K if you process more than $20,000 in a year. You'll receive a copy of the form for your tax records. This is true for all payment processors, not just Square. Keep your own records of expenses and income so you can file your taxes accurately.
What if I want to cancel my Square account?
You can cancel anytime with no penalty or cancellation fee. Your account closes, and you stop receiving payouts. Any pending transactions still process, and you'll receive a final payout for those. If you bought hardware like the Square Terminal, that's yours to keep — Square doesn't ask for it back.
