Having used Sage 50 for years being introduced to Sage Intacct in my new job was a rollercoaster. It isn't as easy to use or straight forward as Sage 50 was, nor other cloud based accounting systems I have used in previous employments (such as Xero). It has taken a mountain of time to train on and still isn't very easy to navigate 6 months down the line. It has its uses such as multi-entity accounting which is the only bonus of it at my current job.
