I like that it lets me enter my personal information for myself, as well as all of our clients' info at once! It's very easy to use- just input your data into each section you want them in (name/address etc) then go ahead with sending out estimates or invoices; they're right there waiting when finished!! Sometimes takes awhile from entering first time through till actually seeing an invoice but not too long really-- about 1 hour maybe? Not many downsides so far.
Just be prepared if using thisβ¦
