Odoo standard (no cutomizations)

Odoo is a multi-tenant system: a single Odoo system may run and serve a number of database instances. It is also highly customizable, with customizations (starting from the modules being loaded) depending on the "current database"

For Odoo online(SAAS) users, you first need to migrate to the Odoo.sh platform before installing Odoo Multichannel Woocommerce Connector because Odoo restricts third-party software installations on Odoo online(SAAS)
