For US merchants, Shopify Payments is the best payment gateway because it is natively integrated and waives Shopify’s 0.6% to 2.0% third-party transaction surcharge. For maximum checkout conversion, pairing Shopify Payments with secondary trust options like PayPal, Shop Pay Installments, and Authorisation platforms (e.g., Stripe, Authorize.net) ensures high authorization rates and covers preferred customer payment methods.

At Pinetrix, we architect frictionless checkout stacks and optimize payment flows through our specialized e-commerce services to reduce cart abandonment and increase net revenue.

The Hidden Penalty: Understanding Shopify’s Third-Party Surcharge

The most critical factor US store owners oversee is Shopify’s third-party transaction fee structure.

If you bypass Shopify Payments and route transactions through external gateways (like Standalone Stripe, Authorize.net, or NMI), Shopify imposes an additional transaction penalty based on your monthly subscription plan:

  • Basic Plan ($39/mo): 2.0% extra surcharge per order.

  • Grow Plan ($105/mo): 1.0% extra surcharge per order.

  • Advanced Plan ($399/mo): 0.6% extra surcharge per order.

The Strategic Exception: Enabling PayPal Express Checkout or Shop Pay Alongside Shopify Payments does not trigger third-party penalty fees, allowing you to offer express wallets while keeping processing costs low.

Strategic Multi-Gateway Architecture for Higher Conversions

Relying on a single payment method leads to lost sales. High-performing US brands use a layered checkout strategy:

  1. Primary Gateway (Shopify Payments): Captures standard credit card transactions (Visa, Mastercard, Amex) and enables mobile wallets like Apple Pay and Google Pay.

  2. Accelerated One-Tap (Shop Pay): Increases conversion rates by up to 50% for returning shoppers through pre-saved shipping and payment info.

  3. Buy Now, Pay Later (BNPL): Integrating Shop Pay Installments, Affirm, or Klarna increases Average Order Value (AOV) for orders above $100.

  4. Secondary Express Trust (PayPal / Amazon Pay): Captures shoppers who prefer not to type credit card numbers directly onto new websites.
