Hey everyone, our current online store is struggling to handle our growing sales volume and we need a complete upgrade—moving beyond basic platforms to something custom and scalable. I’m looking specifically for a dedicated ecommerce website agency. Someone suggested a particular firm, but I want to make sure I hire a true expert in high-volume e-commerce.

What are the critical things I should look for in their case studies to ensure they can deliver on complex inventory management, advanced payment gateways, and serious speed optimization? If you’ve had a great experience with an agency specializing in conversion-focused e-commerce builds, please share your thoughts and recommendations!
