Stripe vs Alternatives: What Recruiters Should Know

Understanding the payment landscape helps you evaluate transferable skills and make informed decisions.

Payment Processor Comparison

When Companies Choose Stripe

• Developer velocity: Best-in-class documentation and SDKs
• Subscription complexity: Native support for trials, prorations, metered billing
• Marketplace needs: Connect handles complex multi-party payments
• Modern stack: Webhooks, idempotency keys, and API-first design
• Global expansion: Single integration for 135+ currencies

When Companies Choose Alternatives

• Existing PayPal users: Consumer trust in PayPal checkout button
• Retail/in-person: Square's hardware integration
• Enterprise scale: Adyen's negotiated rates and account management
• Specific markets: Local processors for regulatory requirements

Skill Transfer Between Platforms

The core concepts transfer across payment platforms:

• Idempotency: All platforms require handling duplicate requests
• Webhooks: Event-driven architecture is universal
• PCI compliance: Data handling rules apply everywhere
• Fraud prevention: Similar patterns across processors
• Subscription logic: Billing cycles, prorations, dunning

A senior Braintree developer can become productive with Stripe quickly. The fundamentals matter more than the specific API.

Payment Integration Patterns: Beyond Basic Checkout

Most tutorials show simple checkout integration. Production systems require much more:

The Reliable Webhook Pattern

Webhooks are how Stripe notifies your system about events (successful payments, failed charges, subscription changes). They're also the most common source of payment bugs.

The Problem:

• Webhooks can arrive out of order
• Your server might be down when Stripe sends an event
• The same event might be sent multiple times
• Your database write might fail after processing

What Senior Developers Do:

1. Verify webhook signature (prevent spoofing)
2. Check if event was already processed (idempotency)
3. Process in a transaction with rollback capability
4. Return 200 immediately, process async if slow
5. Implement reconciliation jobs to catch missed events

Interview Signal: Ask candidates what happens if your webhook endpoint returns 500. Senior developers know Stripe retries for up to 3 days with exponential backoff.

Idempotency: The Non-Negotiable Pattern

Idempotency ensures that retrying a failed request doesn't create duplicate charges. This is critical for payment systems.

The Problem:

1. Customer clicks "Pay" button
2. Request sent to your server
3. Your server calls Stripe
4. Stripe charges the card successfully
5. Network timeout before response reaches you
6. Customer clicks "Pay" again
7. Without idempotency: customer charged twice

The Solution:

// Generate idempotency key from order ID or unique identifier
const idempotencyKey = `order_${orderId}_attempt_${timestamp}`;

const paymentIntent = await stripe.paymentIntents.create({
  amount: 2000,
  currency: 'usd',
}, {
  idempotencyKey,
});

Interview Signal: Ask candidates how they'd handle a user clicking the payment button twice. Senior developers immediately mention idempotency keys and client-side button disabling.

The Subscription Lifecycle

Subscription billing has more edge cases than most developers expect:

State Transitions:

• Trialing → Active → Past Due → Canceled
• Active → Paused → Active
• Monthly → Annual (proration)
• Individual → Team (seat changes)

Common Gotchas:

• Prorating upgrades mid-billing cycle
• Handling failed renewal attempts (dunning)
• Tax calculation for different jurisdictions
• Invoice generation timing
• Credit application for downgrades

PCI Compliance: What Non-Experts Need to Know

PCI DSS (Payment Card Industry Data Security Standard) governs how cardholder data is handled. Stripe simplifies compliance, but developers must understand the boundaries.

Stripe's Compliance Model

Stripe Elements / Checkout (Recommended):

• Card details entered in Stripe's iframe
• Your server never sees card numbers
• Simplest compliance: SAQ-A (self-assessment questionnaire)
• No cardholder data touches your infrastructure

Stripe.js with Custom Forms:

• Card details tokenized client-side before submission
• Your server receives tokens, not card numbers
• Requires SAQ-A-EP (slightly more involved)
• More design flexibility

Direct API with Card Numbers:

• Your server handles raw card data
• Full PCI DSS compliance required
• Annual audits, penetration testing, extensive controls
• Almost never appropriate for most companies

What This Means for Hiring

Most Stripe integrations should use Elements or Checkout. Candidates who suggest handling card numbers directly either:

1. Don't understand PCI implications
2. Are working on legitimate edge cases (rare)

Interview Signal: Ask candidates how they'd build a payment form. If they suggest storing card numbers in their database, that's a red flag. If they mention Stripe Elements or Checkout, they understand the compliance landscape.

Recruiter's Cheat Sheet: Spotting Great Candidates

Conversation Starters That Reveal Skill Level

Resume Signals That Matter

✅ Look for:

• Specific transaction volumes ("Processed $2M monthly in subscription payments")
• Failure handling mentions ("Reduced payment failures by 40% through retry logic")
• Compliance awareness ("Maintained PCI SAQ-A compliance")

• Banking/Financial services: Understanding of financial regulations
• Other payment processors: Braintree, Square, Adyen experience transfers

Common Hiring Mistakes

1. Treating Stripe as "Just API Integration"

Payment systems are business-critical. A bug doesn't just cause a 500 error—it causes lost revenue, duplicate charges, or compliance violations. Hire for reliability engineering, not just feature building.

Better approach: Ask about failure modes and recovery strategies, not just happy-path implementation.

2. Not Testing for Webhook Understanding

Webhooks are where most payment bugs live. Many developers have only built synchronous checkout flows and don't understand event-driven payment architectures.

Better approach: Ask candidates to design a subscription renewal system. If they don't mention webhooks, they haven't built production billing.

3. Ignoring Compliance Knowledge

Developers who don't understand PCI compliance might build insecure systems. At minimum, they should know why Stripe Elements exists and when direct API usage is inappropriate.

Better approach: Ask how they'd build a payment form. The answer reveals compliance awareness.

4. Over-Valuing Stripe-Specific Experience

The concepts (webhooks, idempotency, subscriptions, compliance) matter more than Stripe's specific API. A senior PayPal/Braintree developer will learn Stripe's API quickly.

Better approach: Test for payment patterns and reliability thinking, not API memorization.

5. Underestimating Subscription Complexity

Subscription billing seems simple until you handle prorations, dunning, seat changes, annual-to-monthly switches, and tax calculations. This complexity requires experienced developers.

Better approach: Describe your actual billing scenarios and ask how they'd implement them.
