excentos provides you two environments so that you can effectively test and optimize one version of the Product Guide, even while you already productively use another one.
Stage Environment
The Stage environment should be used for testing the Product Guide in your stage or test system. Publishing to the Stage allows you to test and preview your changes in a similar setup as your shop or website. If everything works as expected you can publish the "ready-to-use" Product Guide to the Live (Service) environment.
Live Environment
The Live or (internal use: Service) environment is used for the finished version of the Product Guide that you want to use productively in your shop or website.
