I like how easy it was to use at first glance! It took some time but as soon as you get used they become very intuitive which makes this software extremely user friendly even if your not tech savvy or computer literate!! The only thing i wish would be different about BB are more options when adding new contacts from emails because sometimes its hard finding where exactly what option should go down so thats my biggest dislike. If u r looking into something simple & want ease-of-use then big bang can help solve ur problems while still keeping things organized w/o having too many tabs open up & taking forever to add stuff back after deleting. This has helped me keep track of everything pertaining to clients including client files along side other info such as invoices etc..
