Stripe vs Square vs PayPal: Fees, Webhooks & Which to Pick in 2026

I'm in Encinitas, North County San Diego — small businesses ask me this almost every week. The real answer depends on one thing: where do you actually collect money, and do you need code or not.

Questions people actually search for

Stripe vs Square Fees (2026)

  • Stripe online: 2.9% + $0.30 per transaction
  • Square online: 2.9% + $0.30 per transaction
  • Square in-person: 2.6% + $0.10 (tap/swipe/dip)
  • Stripe in-person: 2.7% + $0.05 (Terminal)
  • Both waive monthly fees at entry level

For in-person volume the gap is small but real. On $10k/month in-person sales, Square saves you ~$20.

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

Text me the exact error message and I'll tell you the fix in under 2 minutes.
