The learning curve to getting familiar can be steep, as it's functions and use case are very much determined by a user's role and department. Once you understand the Sage Intacct environment, it's pretty easy to complete your specific tasks quickly, however navigating to new or unfamiliar functions of Intacct often requires additional training or time.
Take your time to understand how to navigate between the different menus and be sure to "star" your most heavily used items so you can quickly get to what you need.
I'd also like to point out that our instance of Intacct, and I'm sure most, require you to fill in three different fields to sign in, all of which are case sensitive. Due to the sign in being three different fields, saving your password may not always work, or may experience issues whenever you opt to update your password. If your organization utilizes Single Sign On (SSO) you won't experience this issue as often.
