Square’s services: Why small businesses love it
Square is the original mobile payment processing app and card reader. It had high adoption rates when it first launched because it allowed businesses to accept card payments anywhere instead of relying on cash or peer-to-peer payment apps. It also did away with the complex contracts and long-term commitments required by many merchant services.
Unlike most credit card processing companies, Square does not require an application or approval process and has no monthly fees or minimum requirements. Every free Square account has three main functions: payments, POS software, and online ordering.
How does Square work?
Square starts with simple, flat-rate payment processing that includes credit cards, contactless payments, and ACH transfers. Then, it offers various products within its ecosystem that all work together to form a complete small business management solution. However, some solutions, like Payroll, can stand alone.
Square continues to add to its offerings for small businesses, from improvements to the software to new systems. More on what’s new below, but first, let’s dive into Square’s core features.
Easy, flat-rate payment processing
You can use Square to complete credit card transactions online, in your brick-and-mortar store, and on your mobile device when you’re on the go.
Square charges a flat rate price per credit card transaction. This means that the credit card company, customer’s bank, and merchant account processor fees are all wrapped up into one flat-rate fee. This is regardless of the type of card you are processing. The only difference in rates is whether you have to key in the numbers.
Square payment processing fees
Payment Type | Transaction Fee |
|---|---|
In-person, mobile, and gift card payments | 2.6% + 15 cents per transaction |
Online payments | 2.9% + 30 cents per transaction |
Recurring billing and card-on-file transactions | 3.5% + 15 cents per transaction |
Keyed-in payments (virtual terminal) transactions | |
ACH Bank Transfers | 1% with a $1 minimum transaction |
Invoiced payments | 3.3% + 30 cents per transaction |
The advantage of this pricing model is its simplicity. You don’t have to worry about figuring out how much you are paying in credit card processing fees because you know in advance exactly how much you will pay. It’s the same flat rate, no matter what type of card your customer uses.

Top-rated merchant services
Square’s affordable and user-friendly payment processing is one of the best merchant services available for small businesses. In addition to mobile and in-store payments, every free Square account has a virtual terminal, invoicing, online payments, and tools to monitor and dispute chargebacks.

Square drawbacks
While Square has a lot to offer, it is not perfect. Here are the biggest drawbacks of using Square and the most common reasons businesses choose to use an alternative:
- Limited support hours: For certain plans, Square only offers phone support from 6 a.m.–6 p.m. PST, Monday–Friday. If you operate outside of these hours, you may need to wait to get support.
- Inconsistent support quality: The level of support you receive and general product knowledge highly depends on the representative you come into contact with, which we have experienced first-hand in our calls to Square support.
- Payment processing fees: While Square’s fees are transparent and average, they aren’t the lowest on the market. As you can see in our alternatives above, PayPal and Clover offer lower rates, as do some other payment processors.
Frequently Asked Questions (FAQs)
These are some of the most common questions we get about Square.
Square offers a complete point-of-sale system solution. It provides POS software with built-in payments and an ecommerce platform that makes it easy for merchants to set up a business platform and start selling in minutes. Square also provides an array of POS hardware to fit any type of budget.
Yes, Square has no monthly fees and offers a month-to-month contract, so you can use Square even if you only sell occasionally, are a solopreneur, or are a member of an organization. The application process will allow you to specify that you are an individual using Square, and you can also choose a business type to specify the type of product or service you offer.
Once your Square POS is up and running, you will need to pay for the monthly use of the system. If you stay with the free POS software without any add-on services, you only have to pay for the transaction fees that would cost roughly around $250 per month for businesses that process below $10,000 in monthly credit card sales.
Both Square and PayPal offer POS software. However, Square is considered one of the top POS systems in the industry. Both also provide payment processing services, but Square supports more features for in-person and mobile payments. PayPal, on the other hand, offers stronger online payments and is better for international transactions.
The Square POS system comes with its built-in payment processing service, Square Payments. It allows Square businesses to accept credit and debit card transactions, as well as ACH. The beauty of Square Payments is that merchants do not need to apply for the service separately.
Bottom Line
Square has become the go-to solution for pay-as-you-go flat-rate payment processing. Every year, Square continues to enhance the features of its free POS software, including solutions specifically designed for retail, restaurants, and appointment-based businesses like salons, in addition to its generic small business POS. Even more, it offers business tools from payroll and marketing to banking. Overall, we highly recommend Square for small businesses. Visit Square to create a free account.
