I am in business for 4 years and 5 months ago started use this solution to save some time for filing forms, sending invoces, completing and signing proposals.
I must to say that saved time I used for my work and it dramatically increased my productivity. And my staff.
It was not bad first time, but with new devices it became insane horrible. Nothing new, just their not fair attempts to get paid for things people are getting for free or able to have some choice.
