PayPal is for consumer purchases. Stripe is for SaaS.
For subscription billing, usage-based pricing, trials, and the complex billing logic that SaaS requires, Stripe is the clear choice. PayPal's subscription API is limited and its developer experience is a decade behind. The comparison matters when investors or customers ask about it.
Payment platform selection for a SaaS application — or explaining to a customer why you use Stripe instead of PayPal
PayPal is the payment method consumers trust for one-time purchases. Stripe is the infrastructure that developers use to build billing systems.
The specific Stripe advantages for SaaS:
Subscription billing. Stripe's subscription API handles trial periods, proration, plan upgrades/downgrades, billing cycles, and invoice generation. PayPal's subscription API exists but is significantly less capable.
Metered billing. Usage-based pricing where the customer pays per API call, per seat, or per GB — Stripe's meters and subscriptionItems handle this. PayPal has no equivalent.
Billing Portal. Stripe's customer portal is a hosted page where customers can update payment methods, view invoices, and manage subscriptions — with no custom development. PayPal has no equivalent.
Webhooks. Stripe's webhook reliability and the event types available (40+ subscription-related events) make it possible to build subscription state machines that respond to billing events. PayPal's webhooks are less reliable.
Developer experience. Stripe's API documentation, test mode, Stripe CLI, and dashboard are the industry benchmark. PayPal's developer tools are significantly behind.
When PayPal makes sense: B2C e-commerce where PayPal checkout is a customer-preferred payment method. Many SaaS applications support PayPal as an additional payment option alongside Stripe — Stripe processes the card, PayPal processes PayPal wallet. This is different from using PayPal as the billing infrastructure.

B2C customers sometimes expect PayPal. B2B SaaS customers rarely require it. Add PayPal as a secondary option if churn or conversion data shows it matters.
Standard pricing is similar: Stripe 2.9% + $0.30; PayPal 3.49% + $0.49 for most transaction types. For volume pricing, both offer negotiated rates.
