Stripe API vs Paddle Billing API

Compare a mature payments-and-billing platform with a merchant-of-record billing API for SaaS subscriptions.

Bottom line: Use Stripe when you own the payments stack and need broad payment-method and platform coverage; use Paddle when you want a merchant of record to absorb global sales-tax and compliance handling for SaaS subscriptions.

Integration shape

Stripe authenticates with a secret key over HTTP Basic auth and versions behavior per account or request; Paddle uses a bearer API key and positions itself as the merchant of record, which shifts tax and compliance responsibility away from the seller. Both sign their webhooks and expect idempotent event handling.

Where Stripe API wins

Breadth: checkout, payment intents, invoicing, and Connect for marketplaces and platforms, with one of the widest SDK and payment-method surfaces in the industry. You keep full control of the payments stack and how pricing is presented.

Where Paddle Billing API wins

The merchant-of-record model absorbs sales-tax collection, remittance, and much of global subscription compliance — the part SaaS teams most often underestimate. Subscription lifecycle concepts (products, prices, adjustments) are the native vocabulary rather than an add-on.

Verify money movement twice

Payments integrations fail most often at webhooks and retries, not on the happy path. Verify webhook signatures on both providers, use idempotency keys for safely retried writes, keep sandbox and live credentials separate (Paddle documents them as distinct), and recheck commercial terms at purchase time — this catalog deliberately avoids encoding prices that change.
