PrestaShop Enterprise is a Platform as a Service (PaaS), and not a traditional Software as a Service (SaaS). This means that PrestaShop and the partner agency provide and manage the cloud infrastructure, updates, security, and maintenance of the platform, while the merchants retain full ownership and control of their store and their data.
Merchants are responsible for managing their business operations, configuring their store, and overseeing e-commerce activities on a daily basis.
The PaaS model offers greater flexibility and customization than typical SaaS solutions, without the constraints of vendor lock-in.
