Stripe — The Default Choice (For Good Reason)
If you're a SaaS startup processing under $1M/year, just use Stripe. I'm not being lazy — it's genuinely the best option for most teams.
Why it wins:
- The API documentation is the gold standard. Every endpoint is well-documented with examples in multiple languages.
- Stripe Billing handles subscription logic — trials, proration, metered billing, dunning — so you don't have to build it.
- Radar (fraud detection) is included and actually good out of the box.
- Webhooks are reliable and well-designed. The event system makes async payment handling straightforward.
Where it falls short:
- Pricing is flat-rate. At high volume, you're overpaying compared to interchange-plus pricing.
- Payouts in some countries are slow (3-7 business days).
- If you need deep customization of the authorization flow, you'll hit walls.
From experience: Stripe's test mode is the best in the industry. You can simulate almost any scenario — failed payments, disputes, 3D Secure challenges. This alone saves weeks of development time.
Adyen — When You've Outgrown Stripe
Adyen is what you graduate to when you're processing serious volume and need global coverage. They're the payment backbone behind Netflix, Uber, and Spotify.
Why consider it:
- Interchange-plus pricing. At $5M+/year, you'll save significantly compared to Stripe's flat rate.
- True global acquiring — they have acquiring licenses in most major markets, meaning better authorization rates for international transactions.
- Single integration for cards, wallets (Apple Pay, Google Pay), local payment methods (iDEAL, Boleto, Alipay), and BNPL.
The catch:
- Minimum processing volume. They won't talk to you if you're doing less than ~$1M/year.
- Integration takes weeks, not hours. The API is good but not Stripe-level polished.
- Their subscription billing is basic. You'll likely need a separate tool like Chargebee or Recurly.
Braintree — The PayPal Play
Braintree is owned by PayPal, and that's both its strength and its identity. If PayPal is a significant payment method for your customers, Braintree gives you the tightest integration.
Good for:
- Marketplaces that need split payments (Braintree Marketplace)
- Products where PayPal/Venmo adoption is high (US consumer market)
- Companies already in the PayPal ecosystem
Skip it if:
- You're primarily B2B SaaS (PayPal is less relevant)
- You need cutting-edge API design (Braintree's API feels dated compared to Stripe)
- You're expanding into Asia-Pacific (limited local payment method support)
Checkout.com — The Dark Horse
Checkout.com has been gaining ground fast, especially in Europe and the Middle East. They offer competitive pricing and a modern API.
Stands out for:
- Competitive interchange-plus pricing at lower volume thresholds than Adyen
- Strong in MENA and European markets
- Good API with modern design patterns
- Flexible — they'll customize more than Stripe will
Watch out for:
- Smaller ecosystem. Fewer third-party integrations and plugins compared to Stripe.
- Documentation is improving but still has gaps.
- Support quality varies. Enterprise accounts get dedicated support; smaller accounts may wait.
How to Actually Decide
Forget feature matrices. Answer these three questions:
$1-5M → Stripe is fine
>$5M → Get quotes
SEA → Check local methods
MENA → Checkout.com
No → Any works
Complex → Add Chargebee
- What's your annual processing volume? Under $1M → Stripe. Over $5M → talk to Adyen and Checkout.com for pricing. In between → Stripe is still fine, but start getting quotes.
- Where are your customers? Mostly US/EU → any of these work. Southeast Asia → check local payment method support carefully. MENA → Checkout.com has an edge.
- Do you need subscription billing? Yes → Stripe or Braintree have it built in. Others require a separate billing layer.
My recommendation for most SaaS startups: Start with Stripe. Build your payment infrastructure with clean abstractions so you can add a second gateway later. When you hit $3-5M in annual volume, evaluate Adyen or Checkout.com for better rates. Multi-gateway setups also improve reliability — if one goes down, you route to the other.
One More Thing: Don't Build a Payment Abstraction Layer Too Early
I've seen teams spend months building a "gateway-agnostic" payment layer before they even have product-market fit. Don't do this. Use Stripe's SDK directly. When you actually need a second gateway, then build the abstraction. Premature abstraction in payments is expensive because every gateway has different edge cases around refunds, disputes, and webhooks that a generic interface can't capture well.
Build for today, architect for tomorrow. Your payment integration should be reliable and simple — not clever.
