You can use Alexion CRM online from (almost) anywhere in the world as long as you have an internet connection.
After all, the database is in the Cloud, allowing you to use Alexion CRM everywhere.
Attention: Older versions of Alexion CRM are so-called client-server applications. They function in the local network, so with PCs and a server, or with just PCs. If you want to access it from various locations, you can for example use External Worktop.
