Square pros and cons

  • Transaction fees cut into profit
  • Customers have complained about difficulties contacting customer service

Square pros explained

Offers multiple ways to pay

The Square POS system allows merchants to enter customers' cards in multiple ways to process their payments. Customers can pay by:

  • Inserting a chip card
  • Manually entering the card information into the system
  • Tapping a contactless card
  • Swiping a card
  • Using split-pay to split the bill between a group of customers
  • Using online pay and a checkout link you can send via text or email

Square accepts Visa, Mastercard, American Express, Discover, JCB and UnionPay. These can be credit, corporate, debit, prepaid, or rewards cards.

Afterpay is available via Square Online or with Square hardware (registers, stands, terminals). Google Pay, Apple Pay and Samsung Pay are also accepted. Merchants can accept checks with Square POS, too.

Excellent easy-to-use inventory management system

Square lets merchants manage their inventory from any computer. It allows for uploading, downloading and updating inventory data in bulk, which is useful when managing new inventory.

Merchants can also receive a daily stock alert email informing them when items are out of stock or running low.

Additionally, Square POS lets merchants manage inventory at multiple locations and get reports on the cost of goods sold and projected profit reporting.

Wide variety of features

Square POS comes with many available features, including:

  • Magstripe reader that merchants can plug into their iOS or Android phones
  • Tap-to-pay on iPhone, which allows customers to hold their cards or their iPhone near the merchant's phone to pay
  • Contactless and chip reader
  • Square terminal, a hand-held Square POS device that accepts card dips, swipes and taps, and prints receipts
  • iPad swivel stand with a built-in contactless-payment reader
  • Square register, which has a touchscreen for the merchant/cashier and a smaller touchscreen for the customer

Square POS integration is extensive and includes many of the most popular apps and services that small business owners use. Integrations include WooCommerce, Mailchimp, Wix, Acuity Scheduling, Linktree, Groupon, Chowly and SKU IQ.

Square’s integration with some of the best accounting software for small businesses — including QuickBooks, FreshBooks, Zoho and Xero — is especially helpful.

Square cons explained

Square POS does come with cons, however, which are worth taking into account when considering whether this POS system is best for your small business.

Can be slow

Review sites such as Trustpilot, G2 and Capterra show complaints from customers about Square’s POS software slowing down when there are a lot of transactions. During those times, there's sometimes a delay when selecting an item to add to the cart. Other processes can lag, too, such as editing a customer profile or searching for an item. Finally, checkout can be slow, and sometimes the card reader has difficulty reading a customer's card, requiring multiple card swipes to get it to work.

Transaction fees cut into profit

POS providers like Square tend to make the bulk of their money by charging transaction fees. While Square POS fees are comparable to those of other POS systems on the market, it’s worth noting that the transaction fees cut into merchants’ profits.

Hard to contact customer service

Customers indicate through reviews on Trustpilot, G2 and Capterra that it's difficult to get live support and direct customer assistance. Even though Square offers multiple support channels on its website, in practice, it can be time-consuming and complicated to reach a customer representative.

When merchants do get through, customer service sometimes offers unrealistic timelines for resolution. For example, customer service might promise a one- to two-day response, only for it to take days or weeks in reality. Merchants have also cited discrepancies in information from agents when troubleshooting problems.

One of the most frequent complaints merchants have about Square is that it's unpredictable about holding merchants’ funds and suspending accounts. Because Square’s signup process is accelerated, some standard security processes are skipped. Your account could later be flagged in situations of suspected fraud, such as a sudden increase in sales volume or many keyed-in, “card-not-present” transactions. Square can legally hold funds until you complete a form with questions about your business.

Square plans/offerings

Square offers a large lineup of plans, including the key offerings below. Merchants looking for a Square POS bundle can select from several options, allowing them to choose the ideal combination of devices for their business.

Square chip for magstripe

Square's magstripe product is one of the company's most recognizable offerings, having been around for over a decade. This device plugs into a smartphone or tablet audio jack or lightning port, and the Square mobile POS allows merchants to accept card payments anywhere, as long as they have their phone on them. Square provides one magstripe card reader to merchants for free, with a fee for every transaction.

Square reader for contactless cards

Square's contactless and chip reader allows merchants to accept contactless payment, chip cards, Google Pay and Apple Pay. The wireless reader connects to Android and Apple devices via Bluetooth. The cost for the Square Reader for contactless and chip is $49.

Square stand with reader

Square's iPad stand with reader lets you turn an iPad into a POS, and the newest version has tap-to-pay and chip card readers built in. (The previous version required a separate reader to take payments from a phone or card.) Merchant reviews from G2, Capterra and Trustpilot mention that it's easy for customers to figure out how to order for themselves and pay on the iPad even when they haven't used the system before.

Business owners also like being able to add different types of items, discounts and sales using the iPad. The stand is priced at $149.

Square POS terminal

Square's POS terminal comes with a magstripe reader, built-in display, chip reader and receipt printer. Merchants can accept many types of cards using the terminal, including gift cards, rewards cards and prepaid cards for the same transaction fee.

The terminal also allows for the management of cash drawers, a feature that isn't available on smartphones. There's no minimum sales volume required to use the terminal and no contract to lock merchants in. The Square POS terminal is priced at $299. (Financing options are offered at checkout.)

Square pricing

Square’s service pricing is transparent and easy to understand. Every transaction completed through Square POS will have a payment processing fee:

  • 2.6% plus 10 cents for payments in person (Retail Plus plan is 2.5% plus 10 cents)
  • 2.9% plus 30 cents for online transactions or invoices without a customer card on file
  • 3.5% plus 15 cents for manually entered transactions or card-on-file invoices

Merchants receive funds in their bank accounts the next business day or can choose to receive funds instantly for a 1.5% fee. While we wouldn’t rate the Square Checking account among the best business checking accounts, it is free and lets merchants get instant funds transfer for free.
