High-volume stores need scalable payment gateways with robust infrastructure and fast card acquiring to handle large numbers of transactions without delays. Look for providers with strong uptime guarantees and support for batch processing or webhook notifications to streamline backend workflows. Integration complexity varies by platform, but many offer APIs or plugins optimized for performance. It’s also critical to implement caching and asynchronous processing to keep your site fast during peak sales.
