It has an easy to use interface, makes invoices look great with its customizable templates as well allows you do edit them online or offline without any hassle at all! The only thing I dislike about it would be that sometimes when editing my PDFs are not saved properly so if i have made some changes but then decide later in time for example after printing out another document etc., they get lost until next save of course this can happen even while working from computer which means we need double saves (at least). But overall everything works fine otherwise no complaints whatsoever just keep up your regular updates because there's always something new coming along every now & again like adding more features here/"new" ones too :D Keep going forward guys!! Great product by far. We've been using their services since 2013 till date still nothing much improved apart form making things.
