I like that this is an easy way for my staff (and myself) who are busy with multiple tasks in our day-to-, it's nice having everything one place so we don't have time lost searching around from site A or B etc..
It also helps keep track where things need doing when you're not there physically working! Nothing really - but if i had any complaints about fast manager they would be minor ones only e g; sometimes slow loading times could take longer than expected which does get frustrating especially during peak hours / rush hour traffic however rest assured once logged into your account its quick & nd efficient :) Definitely recommend getting yourself set up using their free trial option first before committing too much money just see how useful/efficiently used system works out best after testing different features over several days then make final determination what.
