PayPal and Square are two of the most recognised consumer payment brands in the United States, but they were built to solve very different problems. PayPal began as an online wallet for sending money between people and grew into a checkout button that lives on hundreds of thousands of websites worldwide. Square started as a magstripe reader plugged into a phone and grew into a full point-of-sale operating system for retailers and restaurants. Both can technically serve online and in-person businesses today, but each retains a clear primary strength.
The Short Answer
Choose Square if you sell in person — retail, restaurants, salons, services, or pop-up events where customers pay with a card at a physical terminal. Square's integrated POS hardware, free entry-level software, and immediate next-day deposits make it the easiest path to taking card payments at a physical location. Choose PayPal if you sell online and want a wallet button that captures buyers who already have PayPal accounts, are a freelancer or small seller invoicing clients, or operate in markets where PayPal has stronger consumer recognition than alternatives. Many hybrid businesses run both — PayPal for online checkout supplementation, Square for the physical storefront.
Pricing and Fee Structures
For online card transactions, PayPal charges 3.49% + 49¢ on PayPal-wallet checkouts and around 2.9% + 30¢ on standard cards (similar to Stripe). Square charges 2.9% + 30¢ for online sales — meaningfully cheaper than PayPal-wallet checkouts. For in-person card transactions, Square charges 2.6% + 10¢ — the lowest among major mainstream processors. PayPal's in-person rate via the Zettle by PayPal device is 2.29% + 9¢, also competitive. The biggest fee gap is on PayPal wallet conversions: at 3.49% + 49¢, they cost noticeably more than card-only processing on either platform, reflecting the value of the wallet network.
Hardware and In-Person Tools
Square's hardware is its core differentiator: the free magstripe reader, $49 contactless reader, $299 Square Terminal, and the $799 Square Register make it possible to take card payments at a physical location within a day. The same Square account also handles e-commerce, invoices, and recurring billing through one dashboard. PayPal acquired iZettle in 2018 (rebranded as Zettle) to enter the in-person market, but the hardware and POS software ecosystem remains less polished than Square's. For physical retail or restaurants, Square is the more capable platform; for businesses that take occasional in-person payments alongside an online business, Zettle is acceptable.
Online Checkout and Brand Recognition
PayPal's primary advantage is brand recognition — the company reports a large global active-account base; see PayPal's investor disclosures for current figures. Many of those users specifically prefer to pay through their PayPal wallet, and adding the PayPal button to a checkout page is associated with higher conversion among buyers who already have PayPal accounts. Square's online checkout works well but lacks the wallet-network effect — customers see a standard card form. For online businesses targeting international or older buyers, offering PayPal as a secondary option alongside another processor is often associated with conversion uplift; for businesses targeting younger, mobile-first buyers, the lift is smaller.
Vertical Tools and Ecosystem
Square offers a deep set of vertical-specific products: Square for Restaurants (table management, kitchen display, online ordering), Square for Retail (inventory management, vendor management, barcoding), Square Appointments (booking software for service businesses), Square Payroll, and Square Loans. The integration is genuinely useful — running a restaurant entirely on Square is operationally simpler than stitching together separate POS, payroll, and lending tools. PayPal's ecosystem is broader in branding (Venmo, Zettle, PayPal Working Capital) but less integrated; the products feel more like a portfolio of acquisitions than a unified operating system.
Who Each Platform Is Best For
Choose Square if you run a retail store or restaurant, want POS hardware and software bundled in a single account, are a service-based business sending invoices and accepting in-person payments, or value the deep vertical-specific products (restaurants, retail, appointments). Choose PayPal if you run an online business and want to add a recognised wallet button to boost conversion, are a freelancer or small seller invoicing clients in multiple countries, or specifically benefit from PayPal's consumer brand among older buyers. The best answer for many businesses is to use both: Square for the storefront, PayPal as a secondary online checkout option.

How to Choose a Platform
- If you sell in person at a physical location: Square. The integrated hardware and software bundle is the fastest setup available.
- If you sell online and target older or international buyers: offer PayPal as a secondary option to capture conversions.
- If you run a restaurant: Square for Restaurants is purpose-built and outperforms generic alternatives.
- If you sell mainly online and want one processor: Stripe (better APIs) or Square (better dashboard) — PayPal works as a wallet button alongside.
- If you operate cross-border and need international wallet acceptance: PayPal's coverage in 200+ markets is unmatched.
Frequently Asked Questions
Are PayPal and Square fees comparable?
For online card transactions, the headline rates are similar but PayPal-wallet checkouts cost more (3.49% + 49¢ vs Square's 2.9% + 30¢). For in-person transactions, Square is meaningfully cheaper (2.6% + 10¢) than most alternatives, including PayPal's Zettle device (2.29% + 9¢, which is technically lower but with weaker hardware). The biggest cost factor is the mix of card-only vs wallet checkouts on PayPal — wallet checkouts are convenient but expensive.
Can I take in-person payments with PayPal?
Yes — PayPal owns the Zettle hardware (formerly iZettle), which charges 2.29% + 9¢ per in-person transaction. The reader costs around $79 and connects via Bluetooth to a phone or tablet. Zettle is functional but the POS software ecosystem is less mature than Square's. For occasional in-person payments alongside an online PayPal business, Zettle is convenient. For businesses where in-person sales are the primary channel, Square is the more polished platform.
Which integrates better with e-commerce platforms?
Both integrate with Shopify, WooCommerce, BigCommerce, Wix, and most major platforms. PayPal's integrations tend to be deeper and more universally available — many platforms offer PayPal as a one-click integration. Square has solid integrations but the dispute and refund workflows can feel less polished, especially on platforms outside Square's direct ecosystem. For Shopify specifically, neither is the default — Shopify Payments (powered by Stripe) is the recommended option, with PayPal and Square as common secondary methods.
Should I use both PayPal and Square?
For many businesses, yes. The most common pattern: Square as the primary processor for in-person sales (because of its hardware and POS software) and PayPal added as a secondary online checkout option to capture conversions from buyers who specifically prefer PayPal. The cost is some additional dashboard management; the benefit is conversion lift on the online side and lower in-person fees. For pure online or pure in-person businesses, picking one is usually simpler.
