Payment Gateway Integration: Stripe, PayPal, and Square Compared

Payment processing is the backbone of e-commerce. Choose the wrong gateway and you lose sales to failed transactions, high fees, or a clunky checkout experience. Here is an honest comparison of the three major options.

Stripe

Best for: Businesses wanting the most developer-friendly, customizable payment processing.

• Standard rate: 2.9% + $0.30 per transaction
• Supports 135+ currencies
• Recurring billing and subscription management built in
• Excellent developer documentation and API
• Fraud detection included (Stripe Radar)
• Funds available in 2 business days (Instant Payouts available for a fee)

PayPal

Best for: Businesses that want customer trust and international reach.

• Standard rate: 2.99% + $0.49 per transaction
• 400+ million active accounts worldwide
• Buyer protection increases customer confidence
• PayPal Credit offers customers financing options
• Simple integration for most platforms

Square

Best for: Businesses that sell both online and in-person.

• Online rate: 2.9% + $0.30 per transaction
• In-person rate: 2.6% + $0.10 per transaction

Our Recommendation

Use Stripe as your primary processor and offer PayPal as an alternative. This combination covers the majority of customer preferences. Add Apple Pay and Google Pay through Stripe for mobile optimization. If you have a physical location, consider Square for unified online and in-store processing.
