- Product, option and category management
- Cart, checkout and order lifecycle
- Customer accounts, wishlists and order history
- Basic admin dashboard and reports
- Multi-language and multi-currency storefronts
what you lose
- 13,000+ marketplace extensions and themes
- Cheap freelance support from developers who already know OpenCart
- Prebuilt payment and shipping modules for long-tail regional providers
- Community-tested upgrade scripts
