PrestaShop

PrestaShop is an open-source eCommerce application for creating and operating online stores. It provides a back office to manage catalog, orders, customers, and storefront presentation, and it can be extended through a large ecosystem of themes and modules.

Key Features

• Storefront + back office for managing products, categories, attributes/variants, pricing, and inventory
• Order lifecycle management (carts, checkout, payments, invoices/credit slips, returns/RMA depending on configuration)
• Customer management with groups, addresses, and account features
• Multi-store support to run multiple shops from one back office
• Multilingual and multi-currency capabilities with localization for taxes and regions
• Shipping and carrier configuration, taxes, and promotions (vouchers/discount rules)
• Extensible architecture via modules/add-ons and theme system
• REST/Webservice API for integrating products, orders, and customers

Use Cases

• Small-to-mid sized retail store needing full control of catalog, checkout, and operations
• Multi-brand operator managing several storefronts from one admin
• Merchants integrating an eCommerce backend with external ERP/PIM/fulfillment via API

Limitations and Considerations

• Many advanced capabilities (specific payment providers, marketplace connectors, SEO tools) are typically provided by modules and may be paid
• Major upgrades can require careful planning due to theme/module compatibility

PrestaShop is a mature, widely-used eCommerce stack with a feature-rich admin and a strong extension ecosystem. It fits teams that want a customizable PHP-based storefront and operational tooling without relying on a hosted commerce provider.
