Square offers a powerhouse suite of payment processing and small business management tools. With transparent fees, a full array of payment options and streamlined sell-anywhere features, it’s no wonder Square has few rivals. Thanks to its beginner-friendly design, learning how to use Square to process credit cards takes only minutes. You can start accepting payments immediately after you set up your new Square account.

What Is Square?

Square is a cloud-based service-as-a-software (SaaS) solution that packs payment processing, online and in-person sales, invoicing, business management and much more into one streamlined, economical system.

You can use Square to process credit cards, plus accept an array of other payments, including automated clearing house (ACH) check payments, Apple Pay, Google Pay and Cash App Pay to name a few. Square also lets you accept payments anywhere. Its mobile and retail point-of-sale (POS) software supports in-person and in-store sales and online tools support e-commerce stores, online service providers, online invoices, keyed-in payments and more.

Square accounts have no monthly fees or long-term contracts, and you can cancel at any time without penalty. So, for most users, the only ongoing cost of using Square is your payment processing fees.

Square does offer paid add-ons, such as payroll, email marketing, and advanced POS systems for retail and food service. These add monthly costs but are still very competitive with other small business POS systems, especially when you factor in all the free tools Square delivers.

Square’s Payment Options

Square’s versatile payment system lets you process credit cards for all types of mobile, in-store, online and virtual transactions. However, that’s one of the many payment options that Square supports.

Here’s a list of the various payment options you can offer to customers when you use Square:

How To Get Started With Square

Going from sign-up to accepting payments takes just minutes with Square. Once you’ve set up a free Square account, you can start processing payments right away using several online and keyed-in payment methods—even before your card reader arrives.

Before You Begin

Square requires the following information to open an account. Having this handy will speed up the process:

  • Full legal name: Square requires the account holder’s full legal name, adding a business name is optional.
  • Social Security number: Square requires the account holder’s Social Security number; business employee identification numbers (EIN) are optional.
  • Bank account: You’ll need a bank account to receive Square payouts. This can be a personal or business account, or you can set up a new Square bank account during registration.

Set Up Your Square Account

Square makes sign-up incredibly simple with a step-by-step wizard. In the wizard, you select an individual or business account, enter your address and the last four digits of your Social Security number and choose how you’ll sell and accept payments. You can choose to attach your bank account or open a new Square bank account to receive your payments during setup, too. These preferences can be edited in your Square dashboard Settings tab as needed.

Explore Your Square Dashboard

To start using Square to process credit cards, head to your Square dashboard, shown below. Here, you can start accepting payments right away using three tools in your dashboard—the Virtual Terminal, Invoices and Payment Link.

5 Ways To Use Square To Process Credit Cards

With your Square account set up, you’re ready to start processing credit cards and other types of payments using the tools in your Square dashboard and POS app.

1. Use Square’s Virtual Terminal To Process Credit Cards

Square’s Virtual Terminal lets you key in credit card information from phone orders or for in-person sales if you don’t have a card reader available. To process a credit card this way, click on Virtual Terminal in your Square dashboard and select Take a Payment to create a new sale.


Complete the appropriate charge amount and payment type fields and click Charge and your payment is complete.

2. Use Square Invoices To Receive Payments Online

With Square Invoices, you can accept both credit cards and ACH payments immediately upon account sign-up. To process payments using invoices, click on Invoices in your Square dashboard, complete the blanks in the invoice fields, select the available payment options for the invoice, enter your client information and email address and click Send.


Your client will receive an emailed invoice with a link to complete the payment online using one of the selected payment methods.

3. Use Square’s Payment Link To Process Credit Cards

Payment Link is another way to use Square to process credit cards. This sends a payment request to a customer via a text link. Payment Link is a payment method in the Virtual Terminal. Instead of keying in a payment directly, select Send Payment Link, enter your client’s cell phone number and click Send Link.


The text link opens the secure Square Online Checkout. There, clients can choose to pay with a credit or debit card or via Google Pay, Apple Pay or the Cash App.

4. Use the Square POS App To Process Credit Cards

Once installed on your mobile device, you can use Square’s POS app to process credit cards by keying the card information directly into the app or using a Square card reader or register to capture card data physically.

Most users pair the POS app with a card reader or use a retail register to accept credit cards physically, as shown below.

However, the versatile POS app also lets you key in card information to process mobile payments when needed, as shown below.

5. Process E-Commerce Payments

Square supports payment processing for all types of e-commerce stores. If you don’t already have an online store, you can launch a free e-commerce website using Square Online. Simply add product information to your Square dashboard, set up your Square Online shop and you’re ready to receive orders and process online payments.


If you already have your own website on WordPress, Wix, BigCommerce, Ecwid or other top ecommerce platforms, you can connect Square’s payment gateway seamlessly to process credit cards for online sales.

Drawbacks to Square

Square does have a few downsides. Payout holds, account freezes and chargeback issues top the list of complaints from Square users. If Square deems your account has too many fraudulent charges or chargebacks, it can withhold payouts or freeze your account. Essentially, this puts your business on hold until the issue is resolved.

Fee flexibility is another complaint among Square users. While Square does offer fee discounts to businesses processing more than $250,000, it still calls the shots on the fees you pay.

Square competitors can provide lower payment processing rates, especially at higher sales volumes. However, few competitors offer an equivalent suite of business management features and sales tools. The cost of piecing together services and software to duplicate Square’s toolset should be included in any price comparison.


Bottom Line

Square is a convenient and economical way to process credit cards for both in-person and online sales, but that just scratches the surface of all that Square has to offer. Square’s impressive suite of payment, sales and business management tools can be tailored to fit the needs of virtually any startup, side gig or small business. There are a few downsides to using Square, however, its reliability, ease of use and overall value make it a top contender on any list of small business payment solutions.
