The best thing about this tool was its user friendly interface which helped me manage my business easily without any issues at all! Also it has an option to add multiple locations for easy tracking as well so that I never felt alone in managing them properly from one place itself!! It also helps us send out our invoices automatically too but you can't do anything if your internet connection drops or goes down during sending invoice process because we receive emails only when there's no connectivity otherwise nothing happens.
So be very careful while using such tools online even though they are free services provided by their providers always go through few trials first before committing yourself into long term contracts. !
