How this category is scored

Every platform here is scored against the same five components. The Expert Assessment component uses a rubric written specifically for e-commerce platforms.

Core Capability
How well it runs the storefront or the job it exists for.
Conversion & Checkout
Checkout quality, speed and everything that costs sales.
Cost of Ownership
Platform fees, transaction cuts, apps and the real monthly bill.
Extensibility
Themes, apps, APIs and how far it bends before it breaks.
Operations
Inventory, fulfilment, tax and the unglamorous parts.
Performance & Reliability
Speed, uptime and behaviour under a traffic spike.
Support
Access to help when the store is down.
