I like that it has all my accounts in one place so there isn't much for me to do when entering data into other systems or programs because everything is already set up correctly! It does exactly what you need it too without having to train someone new each time something changes which was great since we're constantly changing things around as our needs change. Everything works well together but sometimes if an error occurs while trying to log out it will freeze up the whole system which could be frustrating especially during tax season where this program handles most of our taxes. We've been able to enter invoices faster than ever before using Bis and get paid quicker by our customers.
