When to Pick Stripe
- You sell primarily online
- You need webhooks or API integrations
- You're building subscriptions or recurring billing
- You need Connect for marketplace/platform payments
- Your developer prefers Stripe's docs (they're the best in the industry)
Stripe is the default for any dev-heavy setup. If you're writing code, use Stripe.
When to Pick Square
- You take payments mostly in person
- You want free hardware (Square Reader)
- You run a food truck, salon, or retail shop
- You want a built-in POS app with no setup
- You don't want to write a line of code
Square is the faster start for brick-and-mortar. Zero setup cost, solid mobile POS app.
Stripe vs Square vs PayPal
- PayPal invoices: 3.49% + $0.49 — usually the most expensive
- PayPal checkout: 3.49% + $0.49 for card, less for PayPal balance
- PayPal makes sense only if your buyers already expect it
- Neither Stripe nor Square offer a "Pay with PayPal" button natively
Default to Stripe or Square. Add PayPal only if customers specifically ask for it.
Webhooks & Integration
- Stripe webhooks: best-in-class retry logic, event logs, CLI testing tools
- Square webhooks: functional but fewer events, less tooling
- Both use HTTPS endpoints and signature verification
- Common Stripe webhook issue: wrong secret (test vs. live mode have different secrets)
- Common fix: Dashboard → Developers → Webhooks → Signing secret
If your Stripe integration isn't firing, check that your endpoint URL is HTTPS and returning 200.
Twilio Export Not Working (2026)
- Most common cause: API key expired or wrong account SID
- Check Console → API Keys for revoked credentials
- CSV exports from Twilio Console time out on large date ranges — narrow the window
- Webhook timeouts: Twilio requires a response in under 15 seconds or it retries
- If your webhook is receiving duplicate messages, add idempotency tracking
