I love how easy it is to use for both my team at work as well as our clients! It's so simple that many of them don't even realize they're using an automation tool until after we've been working together awhile!! The only thing about emersion i dislike is sometimes when sending files back to clients if something changes in between uploads or edits then there isn;t any way to go backwards through previous versions without having to start over from scratch again which can be very time consuming especially since most projects are done by word count.
Make sure you give yourself enough time while testing out new modules/features before going live because some things take longer than expected to get implemented properly (and others will have bugs). We started doing client billing via this software last year and haven't looked back once!
