Most Popular Payment Gateways for US Ecommerce
Stripe, PayPal, Square, Authorize.Net, Braintree, Apple Pay — fees, integration cost, and which one fits your Tampa WooCommerce store.
For US WooCommerce stores, Stripe and PayPal are the two essentials — offer both and you’ll process 90%+ of transactions. Stripe charges 2.9% + 30¢. PayPal charges 3.49% + 49¢. Add Apple Pay and Google Pay (free overlays on Stripe) to lift mobile conversions 15-30%. Klarna or Affirm makes sense for AOVs over $200. Square works if you also have a physical Tampa storefront.
The six gateways that matter
You don’t need to integrate every payment method — you need the ones your buyers actually use. In the US, six cover almost everything:
- Stripe — the default for most modern WooCommerce stores
- PayPal — required because 25-30% of US buyers prefer it
- Apple Pay / Google Pay — free wallets that ride on Stripe
- Square — strong if you have a physical Tampa retail location
- Authorize.Net — older, more expensive, sometimes required by legacy merchant accounts
- Klarna / Affirm / Afterpay — buy-now-pay-later for higher AOV
Fee comparison at a glance
| Gateway | Per-transaction fee | Monthly fee | Best for | |—|—|—|—| | Stripe | 2.9% + 30¢ | $0 | Default WooCommerce stack | | PayPal | 3.49% + 49¢ | $0 | Required as second option | | Apple Pay / Google Pay | (rides on Stripe at 2.9% + 30¢) | $0 | Mobile conversion lift | | Square | 2.6% + 10¢ in-person; 2.9% + 30¢ online | $0 | Online + brick-and-mortar | | Authorize.Net | 2.9% + 30¢ + $25/mo + $0.10/transaction | $25 | Legacy merchant accounts | | Klarna / Affirm | 3-6% (paid by merchant) | $0 | AOV $200+ |
The breakdown
Stripe is the cleanest integration for WooCommerce. The official Stripe plugin handles cards, Apple Pay, Google Pay, ACH debits, and increasingly buy-now-pay-later. Settlement is 2 business days. Dispute handling is good. Stripe is the right default for 80% of Tampa ecommerce stores.
PayPal isn’t optional. Roughly 25-30% of US online shoppers prefer PayPal — especially older buyers and anyone wary of entering card numbers. Offering PayPal alongside Stripe lifts checkout completion 8-15%. PayPal’s fees are higher but you don’t pay them if buyers don’t use it. The PayPal WooCommerce plugin is free.
Apple Pay and Google Pay are wallet overlays — they don’t replace Stripe, they ride on top. The conversion lift is real: stores enabling Apple Pay on iOS see 15-30% higher mobile checkout completion. Both are free to enable through Stripe.
Square is worth it only if you also operate a physical Tampa location. Square’s edge is unified online + in-person inventory and customer data. The WooCommerce Square plugin syncs both. If you’re online-only, Stripe beats it.
Authorize.Net is older infrastructure. It’s required if your bank has a legacy merchant account agreement. Otherwise, skip it — the monthly fee and per-transaction surcharge add up.
Klarna, Affirm, and Afterpay let buyers split payments into 4 installments or pay over months. They cost you 3-6% per transaction but lift AOV 20-50% on stores with carts over $200. Worth it for furniture, jewelry, electronics, premium apparel.
Florida-specific considerations
A few things to know for Tampa stores:
- Florida sales tax must be calculated at checkout (6% state + Hillsborough’s 1.5% discretionary). Your gateway doesn’t calculate tax — your store does. See Florida ecommerce sales tax.
- Hurricane-season fraud spikes after major storms — disaster-related charity fraud and stolen-card testing both increase. Stripe Radar and PayPal’s fraud tools both flag this well.
- Chargeback rates for storm-affected shipments require clear shipping policies during named storms. We recommend a shipping holiday banner during NOAA-named storm watches.
What this means for your Tampa store
Default WooCommerce stack for 90% of Tampa SMBs:
- Stripe as primary, with Apple Pay and Google Pay enabled
- PayPal as secondary
- Klarna or Affirm if your AOV is over $200
- Square if you have a physical Tampa storefront
Three things not to do:
- Don’t skip PayPal. You’ll lose 8-15% of completions.
- Don’t pile on every BNPL option. Pick one (Affirm or Klarna) — too many choices kills conversion.
- Don’t run Authorize.Net unless your bank requires it. The fees are obsolete.
If you’re switching from Shopify, note that Shopify Payments locks you in — moving to WooCommerce means setting up Stripe and PayPal separately, but you avoid Shopify’s 0.5%-2% transaction surcharge. Over a $30K/month store, that’s $1,800-$7,200 per year back in your pocket.
