It has made access control very easy. We don't need to share the actual account credentials with any employee. They can work through HootSuite. 

We can also manage all our social media in one interface with personalization. It has improved efficiency and security and has delivered significant cost savings. In the enterprise edition, there is also an option to manage user access, and you can limit or grant access, depending on the business needs. For example, marketing can be given access to analytics, customer support to messages, and social teams to the postings. Also, you can have levels for approvals. 

The main improvement HootSuite offers is allowing my organization to run social media campaigns. Also, it has a social media presence outside of the hours people are able to devote to an organization.

It saves me time.
