I like that it provides all my reports in one place which is really helpful for me as an accountant who has access from home or when travelling! It can be slow sometimes but this depends if you have lots going through at once so don't worry about being slowed down too much by other users using their accounts simultaneously with yours - just keep working away until everything loads up again (it will).
Sometimes there's not enough space available depending how many people are logged into our account; however we've found ways around these problems where possible such as downloading files onto external devices before logging back online etc., otherwise its great though!! We're able to pull information quickly without having multiple spreadsheets open/being out-of date because they update regularly throughout each day.
