Square’s credit card processing gives you a variety of transaction options along with a full suite of business management tools. The real trick is knowing how to use Square for your particular business needs. We’ll show you how to use Square for payments and how to use it to expand your sales reach and manage your entire business.

To start processing credit cards with Square, you first need to open a free Square account, which you can set up in minutes. Once that’s done, you can immediately accept what Square calls keyed-in payments using your smartphone, tablet, computer, or e-commerce website. Square also sends you a free mobile card reader when you sign up. Once you receive your reader, you can physically swipe credit cards using your smartphone or tablet, too.

Processing payments just scratches the surface of all that you can do with Square. You get a full suite of tools for inventory and sales tracking, customer and employee management, invoicing, an online store, and more in your free account. But how you use Square’s many features really depends on how you sell and accept payments.

Here’s a look at the six ways that most Square users accept and process payments. We’ll explore how each works for different business scenarios below.

How to Use Square Mobile Payments to Run Your Business

Square’s mobile POS app is a very powerful sales and inventory management tool that seamlessly ties into your online Square dashboard. With it, you can oversee many aspects of your business using just your smartphone or tablet, such as:

• Track sales – Every mobile sale is tracked in detail and you can access sales reports to help you track growth and make key business decisions. Plus, if you sell via other methods, like online or in-store, all of your sales tie together seamlessly in one system.

How to Use Square to Accept In-Store Payments

Square’s powerful, free POS software can be paired with a checkout register for in-store sales. While you can use the mobile readers covered above for in-store sales, most retail stores and eateries prefer using a checkout register with a cash drawer and receipt printer, like the setup above. For this, you need to:

1. Set up a free Square account – Sign up takes just a few minutes and it’s completely free
2. Choose a checkout register – Options include a Square Stand with iPad and card reader OR the new all-in-one Square Register
3. Add peripherals – Cash drawers, receipt printers, barcode scanners, and mobile card readers can be added as needed
4. Set up your free Square POS software – Add inventory items, tax rates, and other key information needed to create sales

Since Square’s retail POS lets you accept payments many ways, once you have the above in place, you can complete in-store sales any way you wish:

• Standard checkout sales – Use the Square POS register to physically process cards and print receipts
• Phoned-in orders – Key in payments into your POS screen for prepaid deliveries or pick-up orders
• Combine with mobile sales – Complete sales on your shop floor or at dining tables using a mobile card reader with a smartphone or tablet

However you accept payments for your in-store sales, the basic steps are the same:

1. Add items (from your Square POS inventory) to the sale, or set a custom charge amount
2. Automatically apply any taxes or discounts
3. Swipe or key in the customer’s credit card (or select the cash or check payment option)
4. Have the customer sign the screen (for in-person sales)
5. Hit Done to complete the sale
6. Print the receipt or enter the customer’s email or mobile number to send an e-receipt

Of course, the above procedure can be tailored to fit your unique business. You can add a barcode scanner to your Square POS for faster checkout, allow the customer to apply a tip if you run a dining establishment, and much more. Square supports many selling methods in your free Square POS software. See how to set them all up in Square’s in-store POS tutorial.

How to Use Square to Sell Online

Square makes it very easy to expand your existing business into online sales or launch a completely new business online. You have two options for using Square for online sales:

1. Use Square’s free online store feature – Every free Square account includes a free online store that integrates directly with your existing Square inventory list. This is the fastest, easiest, and cheapest way for Square users to start selling online.
2. Use Square with top e-commerce platforms – Top e-commerce platforms, including BigCommerce and Ecwid, integrate with Square if you need more online selling features than the free Square online store offers.

Here’s a closer look at how to use Square for your online sales:

How to Use Square’s Free Online Store

If you already use Square and have inventory items set up, you can quickly launch a free Square online store to sell some or all of your existing products online. Learn how in our Square online store set up guide.

If you’re new to Square, here are the three things you’ll need to do to launch a free Square online store:

1. Open a free Square account
2. Enter products into your Square inventory, with good product photos and product descriptions
3. Decide on a domain name for your website (you’ll create this during your Square online store setup)

How to Use Square with Other E-commerce Platforms

You can use Square as your online payment processor for other e-commerce platforms like Shopify, BigCommerce, WooCommerce, or Ecwid. If online sales are your focus, these platforms offer a stronger set of online sales features than the free Square online store. These platforms charge monthly fees, but Square charges you nothing more to go this route (you just pay credit card processing fees).

A few platforms, like BigCommerce and Ecwid, fully integrate their inventory, sales, and customer tracking data with Square. This can be a major plus if you sell online, in-store, and via mobile. This integration lets you conveniently manage all of your sales functions within Square. To learn more about this option, check out the BigCommerce and Square integration and the Ecwid and Square integration.

To use Square with one of these e-commerce platforms, you need to:

1. Open your free Square account

• Automated, secure online payment processing
• Customer tracking and management
• Inventory management for both online and in-store sales

Next, we’ll look at how to use Square to manage invoices and payments for service businesses.

How to Use Square to Manage Invoices & Recurring Payments

Square lets you create invoices and email them to your customers from both your Square dashboard and POS app. Once received, your customers can conveniently pay invoices using a credit card by clicking the Pay button on their invoice. They can even choose to save their payment information in Square’s secure payment vault Square – Card On File to use for future payments or as a recurring payment.

To use Square for invoicing, you need to:

1. Set up a free Square account – Sign up takes just a few minutes and it’s completely free
2. Generate and send invoices – Create invoices in your Square POS or using your online Square dashboard, then email to customers or print as needed; you can enter inventory items on invoices or create custom charges
3. Track payment status – Online invoice payments record automatically as customers pay; you can also enter check or cash payments, or process phone-in credit card payments within your Square dashboard or app

Recurring payments are a handy feature that Square provides. They’re ideal for automating monthly service fees, say for lawn care or housekeeping services, or monthly tuition or dues. Customers enjoy the convenience of automated payments and you enjoy a steady stream of predictable, on-time income each month.

You use Square’s invoice feature to set up and manage recurring payments. Here is a step-by-step guide that details how to use Square for recurring payments.

How to Use Square Invoice Payments to Manage Your Business

Square gives you a powerful set of invoicing tools to help you track payments and stay on top of late accounts. Best of all, if you combine invoice sales with other types of selling, such as online, in-store, and mobile sales, everything is recorded in your Square dashboard for an accurate view of your entire business.

If you use invoices, you’ll find that Square makes it easy to:

• Create and send single or batch invoices
• Track sales and payments by customer
• Track aging and late-pay accounts
• Assign inventory to sales tickets
• Charge for parts, items, and services on one invoice
• Accept invoice payments via credit card, check, and cash

What It Costs to Use Square Invoices & Recurring Payments

Square’s invoicing and recurring payments feature is free. You aren’t charged for creating or emailing any invoices or setting up recurring payments. Plus, you only pay credit card processing charges for the invoices that are paid by credit card. Cash and check payments cost you nothing.
