I love that it can be used for quick documents, as well or long-form reports which are more professional looking than other online options! It's also very easy of use - you don't need any technical knowledge at all (although there may come times when something does not work quite right).
There was some lag time between uploading my document from our computer into an email address in order send out copies with signatures attached etc., but this has been sorted now so no problems since then :) Definitely recommend using if your business needs good quality printing/document production services without having too much hassle doing them yourself!! We have saved money by reducing paper costs compared against what we would spend going through traditional methods such as faxes / post mailings & photocopies sent around internally.
