What are apps or modules in Odoo 8?
There are several versions of Odoo, currently it is 11, but I particularly use 8 due to the availability of some specific modules for my business model, however, it is recommended to use that version where the technologies and modules are more adapted to your needs , as well as its ability to update.
In all versions of Odoo 8 there is a marketplace of modules that allow to increase or improve the functionalities of the Erp, many of these modules are free and open source, others are private and with different values. Regardless of the nature of the module, these can be installed and activated in a simple way, directly affecting ERP transactions and all related modules.
Odoo modules or apps ( which the organization recognizes as stable ) can be found in Odoo Apps , where you can filter them by the version they are compatible with, their area of ​​impact, their price, and other features that will allow you to find modules that solve the needs of your business.
