Best Companies For Payment Gateways — How to Choose

Why Your Payment Gateway Choice Matters

Your payment gateway is the backbone of your online sales. For US e-commerce businesses, it needs to support popular payment methods including cards, Apple Pay, Google Pay, PayPal, and ACH transfers — while maintaining full PCI DSS and CCPA compliance. A poorly chosen gateway can lead to abandoned carts, security breaches, and lost revenue.

Essential Features to Look For

When evaluating payment gateways for your US business, prioritise these features.

• ACH payment support — Bank-to-bank transfers offer lower fees than card payments, ideal for B2B and recurring billing.
• Multi-state tax handling — Sales tax varies by state and even by city. Your gateway should integrate with tax calculation services.
• Fraud prevention — Advanced fraud detection with machine learning and customisable risk rules.
• Mobile optimisation — Over 55% of US e-commerce transactions now happen on mobile devices.
• CCPA-compliant data handling — California's privacy law applies to businesses serving California consumers regardless of location.

Pricing Models Compared

US payment gateway pricing typically falls into three models: flat-rate (e.g., 2.9% + $0.30 per transaction), interchange-plus (e.g., interchange + 0.15% + $0.10), and tiered pricing. For most US businesses processing under $100,000 annually, flat-rate offers simplicity. Above that threshold, interchange-plus usually delivers better value.

Integration and Support

Consider how the gateway integrates with your existing e-commerce platform (Shopify, BigCommerce, WooCommerce), accounting software (QuickBooks, FreshBooks), and CRM. US-based customer support with 24/7 availability is increasingly standard among top providers.
