Payment Processing: Stripe vs PayPal vs Square Compared
Choose the right payment processor for your business model, volume, and customer base.
Payment processing is the financial backbone of any online business. The three dominant processors — Stripe, PayPal, and Square — serve different business models and customer segments.
Stripe (2.9% + $0.30/transaction) is the developer's choice for online payments. Its API-first approach enables custom checkout experiences, subscription billing, marketplace payments, and complex billing logic. Stripe Atlas helps incorporate businesses and open bank accounts. Best for SaaS, marketplaces, and tech companies.
PayPal (2.99% + $0.49/transaction) offers the highest consumer trust. Its 400+ million active accounts mean many customers already have PayPal wallets, reducing checkout friction. PayPal's buyer protection increases consumer confidence. Best for e-commerce and international selling.
Square (2.6% + $0.10 in-person, 2.9% + $0.30 online) bridges physical and digital commerce. Its POS hardware handles in-person payments while the online platform manages e-commerce. Inventory syncs across channels automatically. Best for retail businesses with both physical and online presence.
Hidden cost comparison: Stripe charges 0.5% extra for international cards and 1% for currency conversion. PayPal's currency conversion markup is 3-4%. Square has no hidden fees but limited international support. All three charge $15 for chargebacks.
Subscription billing: Stripe Billing is the most flexible, supporting usage-based pricing, tiered plans, and prorated upgrades. PayPal Subscriptions handles basic recurring payments. Square doesn't offer native subscription billing.
Our recommendation: Choose Stripe for online-first businesses with technical resources. Choose PayPal for maximum checkout conversion with consumer audiences. Choose Square for omnichannel retail. Many businesses use Stripe + PayPal together to maximize conversion.
