Business Model

As an open-source organization, PrestaShop is faced with the challenge of generating revenues. By leveraging the size and international scope of its open-source community, the company established two main sources of revenue:

• PrestaShop Addons, a marketplace through which merchants purchase custom addons and themes for their stores
• Strategic partnerships with e-commerce industry leaders such as PayPal or Google

Features

PrestaShop has more than three hundred built-in features for managing product listing, payments, shipping, manufacturers and suppliers. PrestaShop uses a web template system which allows users to customize store themes and add new features through add-on modules. The PrestaShop Addons marketplace provides a platform for third-party developers to sell themes and modules to merchants.

Themes

PrestaShop provides a basic responsive theme by default. Users can install or develop their own themes which change the display of the website without altering its content.

Modules

Add-on modules extends the software built-in functionalities. Users may install modules directly within the software administration panel or develop their own.
