Does Integration Count Actually Matter in a Payment Gateway?

The short answer is yes, integrations matter, but not in the way most comparison charts suggest. What really counts is whether your payment gateway has deep, reliable connections to the specific POS, e-commerce, ERP, and CRM tools you already run, and whether its API can support where your business is heading next.
