PayPal vs Square: Complete Comparison
Fee Comparison
Square charges 2.9% + 30 cents for online payments, 2.6% + 10 cents for in-person tap and chip payments, and 3.5% + 15 cents for manually keyed transactions. There are no monthly fees on the basic plan. Square's pricing is flat-rate and consistent, which makes cost prediction straightforward.
PayPal charges 3.49% + 49 cents for standard PayPal Checkout transactions, 2.99% + 49 cents for Advanced Credit and Debit Card payments, and 2.29% + 9 cents for in-person QR code payments. PayPal Zettle (their in-person card reader) charges 2.29% + 9 cents for tap and chip. PayPal's pricing varies significantly depending on which product and checkout method the customer uses, making actual costs harder to predict.
On a $50 online sale, Square costs $1.75 and PayPal Checkout costs $2.24, a difference of $0.49. On a $100 in-person sale, Square costs $2.70 and PayPal Zettle costs $2.38. PayPal is actually cheaper for in-person transactions through Zettle, but Square's in-person experience is substantially better. Most businesses prioritize the overall experience over a few cents per transaction when choosing an in-person payment solution.
In-Person Payment Experience
Square built its business around in-person payments and it shows. The Square POS app runs on any iPhone, iPad, or Android device and handles sales, returns, inventory, customer profiles, and employee management. The hardware is affordable and reliable: the free magstripe reader gets you started, and the $49 contactless reader handles tap-to-pay, Apple Pay, and Google Pay. For permanent retail setups, the Square Stand ($149) and Square Terminal ($299) provide professional countertop solutions.
Square's POS app tracks inventory in real time across online and in-person channels. Sell an item at your market booth, and it immediately updates your online store's stock count. Customer purchases are tracked automatically, building profiles with purchase history that feeds your marketing. Employee clock-in, tip management, and basic scheduling are included free.
PayPal Zettle is PayPal's in-person payment solution, acquired when PayPal bought iZettle in 2018. The Zettle card reader costs $29 for your first device and accepts tap, chip, and swipe payments. The Zettle POS app is functional but less polished than Square's. Inventory management is basic, reporting is limited, and the integration between your PayPal online payments and Zettle in-person payments is not as seamless as Square's unified system.
If in-person sales are a significant part of your business, Square is the clear winner. The hardware ecosystem is deeper, the POS software is more mature, and the unified reporting across channels is better implemented.
Online Payment Experience
PayPal has the advantage for online payments because of consumer adoption. More than 430 million people have PayPal accounts, and many have their payment details, shipping address, and preferred card saved. A customer who clicks "Pay with PayPal" can complete their purchase in two clicks without typing anything. This convenience drives measurably higher conversion rates, especially on mobile devices where form filling is cumbersome.
PayPal also carries a trust signal that matters for smaller or newer online stores. Consumers who have never heard of your brand may hesitate to enter their card number directly on your site, but they trust PayPal as an intermediary. Multiple studies have shown that adding a PayPal button increases checkout conversion by 5% to 15% for stores without strong brand recognition.
Square Online provides a basic but functional ecommerce website builder that is included free with every Square account. You can build a simple online store, accept orders for pickup or delivery, and process payments through Square. The designs are clean but limited, and the feature set is basic compared to Shopify, WooCommerce, or BigCommerce. Square Online works well as a complement to a brick-and-mortar business, but it is not competitive as a standalone ecommerce platform.
Invoicing
Both platforms offer free invoicing, and both do it well. Square Invoices lets you create and send invoices from the app or web dashboard, accept card payments on invoices, set up recurring invoices, and track payment status. The interface is clean and takes about two minutes to create and send an invoice. Processing fees on invoice payments are 3.3% + 30 cents.
PayPal Invoicing has been a core PayPal product for years and is widely used by freelancers, consultants, and service businesses. Creating and sending invoices is straightforward, customers can pay with PayPal or a credit card, and the system supports recurring invoices, partial payments, and estimates. Processing fees on invoice payments are 3.49% + 49 cents, making PayPal's invoicing meaningfully more expensive than Square's per transaction.
For businesses that invoice regularly, Square's lower fees add up. On $5,000 in monthly invoice payments, Square costs $195 and PayPal costs $199. The gap is not enormous, but it grows with volume. The experience of creating and managing invoices is comparable on both platforms.
International Capabilities
PayPal dominates international payments. It operates in over 200 markets, supports 25 currencies, and is a recognized payment brand globally. If you sell physical or digital products to customers outside the United States, offering PayPal as a payment option captures buyers in markets where local card payment infrastructure is limited but PayPal adoption is high.
Square is primarily a US-focused company. It operates in the United States, Canada, the United Kingdom, Australia, Japan, Ireland, France, and Spain. Multi-currency processing is not available for most merchants. If your business sells internationally or plans to expand beyond the US, Square's geographic limitations are a significant constraint.
Business Tools Beyond Payments
Square has expanded into a full business management platform. Beyond payments and POS, Square offers Square Appointments (scheduling and booking), Square Loyalty (rewards program), Square Marketing (email and text campaigns), Square Payroll (employee payroll processing), Square Banking (business checking and savings), and Square Loans (business financing). These tools integrate with the POS and payment data, creating a unified small business ecosystem.
PayPal's business tools are more focused on payments and money movement. PayPal Working Capital and PayPal Business Loan offer financing based on your PayPal sales history. PayPal Business Debit Mastercard lets you spend your PayPal balance directly. PayPal's ecosystem is deeper on the financial side but lacks the operational tools (scheduling, loyalty, marketing, payroll) that Square provides.
Account Stability and Support
Both PayPal and Square have reputations for sudden account freezes and fund holds. PayPal's holds are particularly well-documented: new merchants, merchants with sudden sales spikes, and merchants in certain product categories routinely report funds frozen for 21 days or more. Square's account terminations tend to happen with less warning, sometimes shutting down accounts with a form letter and holding funds for up to 90 days.
Support quality favors Square slightly. Square offers phone, email, and chat support during business hours, and the support team is generally knowledgeable about the full product suite. PayPal's support is available by phone and chat, but wait times are often long and the support representatives sometimes struggle with complex merchant account issues. Both platforms have extensive self-service documentation and community forums.
When to Choose Square
Choose Square if you have a physical retail location, sell at markets or events, need POS hardware, want unified online and in-person reporting, or need operational tools like scheduling, loyalty, and payroll. Square is the right choice for restaurants, retail stores, salons, fitness studios, service businesses with physical locations, and food trucks.
When to Choose PayPal
Choose PayPal if you sell primarily online, want the checkout conversion boost from the PayPal brand, sell internationally to markets where PayPal has strong consumer adoption, or run a freelance or consulting business that invoices clients regularly. PayPal is also the right choice as a secondary payment option alongside another processor like Stripe or Square.
The Bottom Line
Square and PayPal serve different core strengths. Square is a commerce platform built around in-person selling that added online capabilities. PayPal is an online payment platform that added in-person hardware. The best choice depends on where your customers are: if they are standing in front of you, choose Square. If they are on their phones and laptops, PayPal (or Stripe with PayPal as a secondary option) is the stronger play.
