Not all providers are created equal. When evaluating your options, consider: 

• Fees: Transaction, monthly setup, and hidden costs. 

• Integration: How well does the processor integrate with your POS, e-commerce site, or CRM? 

• Customer Support: Do you get a dedicated account manager, or just a support email? 

• Security & Compliance: Ensure PCI DSS compliance, tokenization, and fraud prevention tools are included. 

• Scalability: Can the solution grow with your business and handle multi-location or international expansion?
