Detailed Platform Breakdown
1. Stripe: The Best Choice for SaaS, Tech, and Custom Checkouts
Stripe is the undisputed developer gold standard. If you run a software-as-a-service (SaaS) business, subscription model, or customized e-commerce experience, Stripe's API, Stripe Elements, and native recurring billing engine provide total flexibility.
Net Payout on a $100.00 Sale:
Fee = ($100.00 * 0.029) + $0.30 = $3.20
Net Payout = $100.00 - $3.20 = $96.80
2. PayPal: The High-Conversion Safety Net
While PayPal carries a higher fixed fee (49¢ vs 30¢), its consumer brand recognition is unmatched. Millions of online shoppers refuse to enter credit card numbers on unfamiliar websites, preferring the one-click security of PayPal or Venmo checkout.
Net Payout on a $100.00 Sale:
Fee = ($100.00 * 0.0299) + $0.49 = $3.48
Net Payout = $100.00 - $3.48 = $96.52 (Sellers lose an extra $0.28 per $100 order compared to Stripe).
3. Square: The Omni-Channel Retail Champion
If your business has a physical store, coffee shop, or pop-up market presence alongside your website, Square is significantly more unified than Stripe or PayPal. Square POS software is 100% free with no monthly subscription for standard hardware.
Which One Should You Choose?
- Choose Stripe if you are selling digital products, building custom web applications, or need multi-currency global settlement.
- Choose PayPal as a secondary payment option alongside Stripe to capture the 15–20% of buyers who will only checkout via PayPal balance.
- Choose Square if you sell products or services in person and want an integrated POS inventory system that syncs seamlessly with your online catalog.
