Bitrix24: A complete solution for most complex business needs

Bitrix 24 is one of the most complete systems I have found out there, short of full ERP implementations like Odoo, but even then, it has something, like landing page creation, that those software packages lack. It is so feature rich it can be intimidating at first, and I find it best to implement small portions of it at one time. Also, the self-hosted version is incredibly powerful, but it is imperative to have an experience channel partner if you wish to go that route, as set up and configuration is much less intuitive. The cloud version is much easier to manage yourself (and honestly many integrations seem to work better) but at the same time, you lack a lot of the power of customization.
