Stripe: Developer-First Flat-Rate Pricing

Stripe's 2026 pricing model is flat-rate per-transaction with no platform fee, no setup fee, and an enterprise tier that unlocks 0.05-0.30 percentage point discounts at scale.

Stripe's US standard rate in 2026 is 2.9% + $0.30 for Visa, Mastercard, AmEx, and Discover cards. International cards add 1.5% on top of the base rate. ACH Direct Debit is 0.8% with a $5 cap. Stripe Billing (recurring subscriptions) adds 0.5% on top of the card fee. Stripe Connect (marketplaces) adds 0.25% on top of the standard card fee. Enterprise contracts for merchants processing above $1M per month negotiate 0.05-0.30 percentage points off the published rate through Stripe's sales team (Stripe, September 2026).

# Stripe Python SDK 2026 - create PaymentIntent
import stripe
stripe.api_key = "sk_live_..."

intent = stripe.PaymentIntent.create(
    amount=2999,  # $29.99 in cents
    currency="usd",
    payment_method_types=["card"],
    capture_method="automatic",
    metadata={"order_id": "ord_2026_001"},
)
# Charge: 2.9% + $0.30 = $0.87 + $0.30 = $1.17
# Net: $29.99 - $1.17 = $28.82

The Stripe Python SDK is one of eight first-party SDKs (Node.js, Ruby, Go, Java, PHP, .NET, iOS, Android). Stripe's API has 99.999% historical uptime, a 100ms median latency, and a 99.5%+ accuracy rate on confirmed fraud via Stripe Radar (Stripe Status, September 2026).

Adyen: Interchange-Plus for Enterprise Volume

Adyen's interchange-plus pricing is the closest to a wholesale cost model of the three processors and wins above $10M monthly volume on regulated debit and corporate card mix.

Adyen charges a published processing fee of $0.13-$0.60 per transaction on top of network interchange, with the rate decreasing at $250K, $1M, $10M, and $100M monthly volume thresholds. There is no monthly platform fee, no setup fee, and no PCI compliance fee. Adyen holds direct acquirer licenses in 37 countries, which means cross-border transactions route through local acquirers rather than a US-only acquirer. This typically saves 0.5-1.0 percentage points on cross-border card mix versus Stripe and Braintree (Adyen Sales, September 2026).

Braintree: PayPal-Owned Volume at 2.19% + $0.49

Braintree's PayPal-owned volume tier at 2.19% + $0.49 is the cheapest published rate among the three processors for merchants with heavy PayPal and Venmo mix.

Braintree's standard US card fee in 2026 is 2.59% + $0.49. Merchants processing more than $1M per month through PayPal-owned rails (PayPal, Venmo, PayPal Credit, Pay Later) qualify for the 2.19% + $0.49 tier. Braintree also offers an interchange-plus plan for merchants processing above $5M per month, with rates negotiated by PayPal's enterprise sales team. ACH Direct Debit is 0.75% with no cap, Venmo is 3.5% + $0.49, and PayPal Pay Later adds 4.99% + $0.49 (Braintree, September 2026).

Developer SDKs, Chargebacks, and Fraud Tooling

Stripe wins on developer SDK, Adyen wins on enterprise fraud customization, Braintree wins on PayPal-native fraud rails.

Stripe's developer SDK is the strongest in the industry in 2026 with first-party libraries for Node.js, Python, Ruby, Go, Java, PHP, .NET, and iOS/Android plus Drop-in UI, Elements, and Checkout pre-built components. Stripe Radar ships free with Stripe accounts and scores transactions on 100+ features with 99.5%+ accuracy on confirmed fraud. Adyen RevenueProtect is built into the platform with device fingerprinting, 3DS2, and dynamic risk scoring. Braintree's fraud tools are weaker than Stripe or Adyen because most fraud decisions are delegated to PayPal's existing rails.

Resources and Next Steps

For merchants evaluating Stripe vs Adyen vs Braintree, start with the published pricing pages for transparent rates (Stripe, Braintree) and request an enterprise quote from Adyen for interchange-plus math. Stripe's API documentation is the canonical reference for the developer experience, while Adyen's enterprise sales team provides custom integration support. Most US-based SaaS, marketplace, and DTC companies under $10M GMV default to Stripe; above $10M GMV, model interchange-plus on Adyen's published tiers.
