The Quick Answer
Use Stripe if you are building or customizing an online store, API integration is important, or you need subscription billing. Use Square if you primarily sell in-person and want hardware that works out of the box with a free POS app. Use PayPal as a secondary option when customers request it — its trust recognition is high — but do not use it as your primary processor due to higher fees and chargeback risks.
Side-by-Side Breakdown
Stripe: 2.9% + 30 cents per online transaction, 2.7% + 5 cents in-person, no monthly fee, best developer API in the industry, instant setup, strong subscription and recurring billing tools. Square: 2.6% + 10 cents in-person, 2.9% + 30 cents online, free card reader on signup, integrated POS app and inventory management, strong for retail and food service. PayPal: 3.49% + 49 cents for standard checkout, 2.29% + 9 cents with PayPal Here card reader, widely recognized by customers, higher dispute rates than Stripe or Square, monthly fee for advanced features.
When to Choose Stripe
Stripe is the right choice if your store is built on a platform that integrates with Stripe (Shopify, Squarespace, Webflow, almost everything), if you need subscription or recurring billing, or if you want maximum developer flexibility to build a custom checkout. Stripe Radar (included) has strong fraud detection. The API is genuinely best-in-class — if you have a developer, Stripe gives you more control than any other processor.
When to Choose Square or PayPal
Choose Square when in-person sales are your primary channel and you want an all-in-one POS, inventory, and payment system with free hardware to start. Square's free terminal, POS app, and basic inventory management make it the most accessible entry point for retail and food service. Add PayPal as a checkout option on your website in addition to Stripe or Shopify Payments — some customers specifically look for the PayPal button and will abandon checkout without it.
The Verdict
For online businesses: Stripe. For in-person or retail: Square. Offer PayPal as a secondary checkout option regardless of your primary processor. Do not use PayPal as your only payment method — the fee structure and account hold policies create unnecessary risk for a growing business.
How to Get Started
1. Stripe: create a free account at stripe.com, connect it to your website platform (Shopify, Squarespace, WordPress, etc.), and verify your business details. Payouts typically begin within 2–7 days of your first transaction. 2. Square: create a free account at squareup.com, order the free magstripe card reader, and download the Square POS app. 3. PayPal: add a PayPal checkout button to your existing Stripe or Shopify store via the PayPal app or plugin — you do not need to make it your primary processor.
FREQUENTLY ASKED QUESTIONS
Can Stripe or Square hold my funds?
Yes, both can hold funds during account verification, in response to elevated chargeback rates, or when your processing volume increases suddenly. Stripe holds are typically resolved within 7 days. Maintain low chargeback rates and accurate business information to avoid holds.
What is the difference between a payment processor and a merchant account?
Traditional merchant accounts (from a bank or acquiring bank) separate the underwriting from the processing. Stripe, Square, and PayPal are aggregated processors — they bundle merchant account services into one product, which enables instant setup but gives you less control in dispute situations than a dedicated merchant account.
Do I need a business bank account to use Stripe or Square?
Yes. Both Stripe and Square require a bank account for payouts. Using a personal account is technically allowed in many cases but creates tax and liability complications. Open a dedicated business checking account before accepting your first payment.
