Company Background

Founded by Twitter founder Jack Dorsey and tech entrepreneur Jim McKelvey in 2009, Square offers billing, invoicing, POS, and merchant services tools for small businesses. Square started as a simple POS solution but has since evolved to cover the wide range of services it now provides. Check out our Square merchant services review for more about its payment processing and other merchant services.

Plans & Pricing

Square doesn’t charge one-time or monthly fees — you merely pay per transaction. Thus, you don’t have to be as cautious about signing up for Square. If you don’t like it, you can cancel their services without paying anything. Square has a few different fee structures depending on the way you take payments. Each one is pretty inexpensive, making Square suitable for smaller, low-volume businesses.

2.6% + $0.10/transaction
2.9% + $0.30/transaction
3.5% + $0.15/transaction


Square’s fee per in-person transaction is 2.6% + $0.10 per transaction. You pay this when your client swipes, chips, or taps to pay with their card. This is a bit lower than average, which, as mentioned, makes Square a good option for small businesses that don’t do a lot of volume.


Square bumps the fee to 2.9% + $0.30 per transaction for online payments. Square counts any purchases through Square Online, Square Online Checkout, and the eCommerce API as “online” payments. Additionally, in-app payments and invoice payments count as online payments.


Whether your customer’s card isn’t working when swiping, or they didn’t bring it because their card is on file, you’ll pay 3.5% + $0.15 per transaction. Of course, you pay this higher rate in exchange for the card not needing to be present. Square charges more because stored cards add uncertainty — the card doesn’t need to be there, which is inherently riskier.

Features & Functionality
General Features

Multiple Ways to Get Paid
Square offers a ton of ways to get paid. You can get some hardware from Square for in-person swipe, chip, tap, or manual payments. You can accept payments in-app, via digital invoice creation, online payments through your website, and even through shareable checkout links.

Recurring Invoices
Do you have any regular clients? Perhaps you’re on retainer with a few, providing regular services in exchange for a fixed monthly fee? With Square, you can store your clients’ credit or debit cards and set up automated recurring invoicing. Square automatically charges your client’s card, making it so that neither party needs to remember to pay or get paid.

Payment Reminders
Square offers payment reminders as another automation to help you collect on customer accounts and maximize cash flows. When you create an invoice in Square, you can schedule these reminders ahead of time so you can get back to working on more important matters.

Need some cash for your business to invest in new projects? Square offers merchant cash advances (although they call them loans) through their Square Capital division, so you can exchange a slice of future credit sales for some quick cash.

Square Business Debit Card
Square gives you more control over your business’s income by offering a free business debit card. The moment you make a sale, your debit card becomes loaded with that money. That way, you can quickly and easily spend the money on your business needs.

Alternatively, however, Square lets you transfer funds to your bank account in as little as one business day for free (or instantly for a small fee).
