How Much Can US Businesses Save?

Based on our analysis, US businesses processing $50,000–$500,000 annually could save between $2,500 and $12,500 per year by switching to a more competitive provider. The biggest savings typically come from moving away from flat-rate pricing to interchange-plus models as your volume grows. Understanding state-specific sales tax implications on processing fees is also critical.

Compliance and Regulation

US payment processors must comply with federal regulations including the FCRA for fair credit practices and PCI DSS for card data security. In California, the CCPA adds additional requirements for consumer data protection. State-specific regulations may also apply depending on where your business operates, making it important to choose a provider that handles multi-state compliance.
