What to Look For
Total Cost of Ownership
E-commerce costs go beyond the monthly platform fee. Factor in transaction fees, payment processing rates, app/plugin costs, theme costs, and hosting. A $29/month platform with 2% transaction fees can cost more than a $79/month platform with no transaction fees at scale.
Conversion Optimization Features
Your store needs to convert visitors into buyers. Look for fast page load times, mobile-optimized checkout, abandoned cart recovery, one-click upsells, and A/B testing capabilities. Even small conversion improvements compound into significant revenue gains.
Inventory & Order Management
As you scale past a few products, inventory management becomes critical. Evaluate multi-location inventory tracking, low stock alerts, automated reorder points, and integration with fulfillment services or 3PLs.
App Ecosystem & Extensibility
No platform does everything perfectly out of the box. A strong app marketplace lets you add reviews, loyalty programs, email marketing, and specialized features without custom development. Check that key integrations exist before committing to a platform.
