Best thing about this program has been it's affordability as well I mean after reading other reviews regarding difficulty with setting up, ease of use etc so far best i have seen in terms off price point for user friendly experience! Nothing but great time waster!! You must try out W-to bill if you are looking at any form or option that will make your life lot easier because its one stop shop everything right from payment gateway integration all done within single window/single app which makes work much simpler than before!! Also customer services always there when needed no matter how small queries we might be having! So nothing dislike really just need more customers feedbacks & suggestions where can add some additional features would also help us grow further. Integration issue (I guess) not related directly though our own system had problems while transferring files into database tables hence couldn't sync data I like that it lets me keep track of time spent, hours worked etc for each client or project with ease! It does take some getting used too but not much once you know how easy this program can be when using all its features (and there are many!). The fact i am able record everything in one place makes my job sooo easier especially as sometimes clients will ask questions about previous work done which they don't remember at times - therefore if we use WBI then those records stay put!!
