# General ## What are products? Products summarize an activity with all its characteristics. *(For example an overnight stay at the Hotel Schweizerhof Lucerne with all the detail information)* Products consist of [product templates](https://help.advatra.com/books/knowledge-base/page/product-templates "Product templates") and [subproduct templates](https://help.advatra.com/books/knowledge-base/page/subproduct-template "Subproduct template"). The following properties are attached to a product: 1. **Supplier** *(Attached to the hotel night is the supplier: Hotel Schweizerhof Luzern AG)* 2. **Product category**: *(Category: 5-star Hotels)* 3. **Location** *(Large: Switzerland, Medium: Lucerne)* A trip consists of several products. Products are therefore the basis for a trip. In order to use products, services (main service and/or additional service) have to be assigned. Products can be created in the administrator area and added to documents.

You can also create a new offer, add the elements and prices you like there and save the product to your library!
