Stripe vs Square vs PayPal: Which One Should You Use?
All three charge similar fees. The real difference is setup friction, hardware ecosystems, and what happens when something goes wrong. Most businesses end up using two of these — one for in-person, one for online. Here's how to pick without wasting three weeks testing all of them.
⚡ 30-Second Decision Tree
You run a physical store/restaurant/service business: Start with Square. Free hardware, built-in POS, zero monthly fee.
You sell online or run a subscription business: Use Stripe. Best API, cleanest checkout, supports every payment method.
You sell on eBay or to international buyers who don't trust you yet: Add PayPal as a checkout option. Buyers trust the logo.
You do high-volume B2B invoicing: Stripe or PayPal. Square's invoicing is weak.

The Honest Truth About All Three
Stripe has the best developer experience but requires someone technical to set up custom flows. If you just want a "buy now" button, Stripe Checkout works fine — but you're paying for flexibility you may not use.
Square wins for physical businesses because the hardware "just works" and the POS is included. But their customer service is harder to reach than Stripe's, and account holds happen with little warning.
PayPal is trusted by buyers but hated by sellers. Frequent account freezes, opaque dispute processes, and slow fund releases make it painful for anyone doing volume. Use it as a checkout option, not your primary processor.
Most San Diego businesses I talk to end up using two: Square for in-person + Stripe for online, or Stripe for everything + PayPal as an optional button for paranoid buyers.
When Each One Causes Problems
Stripe Headaches
Issue: Account flagged for "high risk" with no clear explanation. Fix: Call support immediately — they're responsive. Provide business docs and transaction history.
Issue: Radar (fraud detection) blocks real customers. Fix: Tune Radar rules manually. Too strict = lost sales.
Square Headaches
Issue: Account limited or closed suddenly (common for new accounts doing $10K+ weeks). Fix: Risk team review takes 3-5 days. Have backup processor ready.
Issue: Chargebacks auto-deducted from your account before you respond. Fix: None. Square sides with buyers by default.
PayPal Headaches
Issue: Funds held for 21 days on new accounts. Fix: Deliver tracking numbers, wait it out, or switch processors entirely.
Issue: Business verification stuck or documents rejected. Fix: See our PayPal troubleshooting guide.
Common Questions
Which has the lowest fees: Stripe, Square, or PayPal?
All three charge 2.9% + 30¢ for online card transactions. Square and Stripe offer slightly lower in-person rates (2.6-2.7%). Differences show up in monthly fees, chargeback costs, and volume discounts. PayPal's international fees are often higher (up to 4.4%).
Can I use all three at the same time?
Yes. Many businesses use Square for in-person (hardware ecosystem), Stripe for online/subscriptions (API flexibility), and PayPal as a checkout option (buyer trust). They can all feed into QuickBooks or Xero for unified accounting.
Which is fastest to set up?
Square wins for speed — 15 minutes to first payment. PayPal Business takes 1-3 days for verification (longer if documents are rejected). Stripe is fast for basic setup but requires more configuration for custom payment flows.
Which is best for international payments?
Stripe supports 135+ currencies and has the cleanest multi-currency handling. PayPal works globally but conversion fees are high (3-4%). Square is primarily US/Canada/UK/Australia focused.
Do I need a business bank account for all three?
Not technically. You can link personal accounts to all three, but PayPal Business and Stripe strongly prefer business checking for verification. Square is more flexible. For tax and liability reasons, use a business account once you're doing real volume.
Which has the best fraud protection?
Stripe's Radar is industry-leading and uses machine learning. Square has decent built-in fraud detection. PayPal protects buyers aggressively but sellers less so — expect to lose disputes even with tracking proof.
