3. Shopify Payments - Best for Shopify Stores ($0 extra, 2.9% + $0.30)

Zero additional transaction fees (third-party gateways add 0.5-2% on top of processing). Native integration eliminates configuration. Shop Pay checkout converts 1.72x better than regular checkout.

4. Adyen - Best for Enterprise ($0/mo, Interchange++)

Custom pricing for high-volume merchants. Single integration for 250+ payment methods globally. Powers Uber, Spotify, Microsoft. Overkill for small stores but excellent for $1M+ annual volume.

5. Square Online - Best for Omnichannel ($0/mo, 2.9% + $0.30)

Unified in-store + online inventory and payments. Free online store builder. Best for businesses selling both online and in-person.

Checkout Optimization Tips

1. Offer guest checkout: 34% of abandoned carts are due to forced account creation
2. Show multiple payment options: Card + PayPal + Apple Pay increases conversion 12%
3. Display trust badges: SSL seal, money-back guarantee, security logos
4. Minimize form fields: Name, card number, expiry, CVC. Thats it.
5. Enable one-click checkout: Stripe Link, Shop Pay, or Amazon Pay

The best gateway depends on your platform. Shopify stores should always use Shopify Payments. Everyone else should default to Stripe.
