What do you like best?
I love the way I can insert my signature without the need to print out a document, sign it, then scan it before emailing it. I save myself a trip to FedEx (as I don't own a printer), where I would spend a few cents or dollars on a paper which needed to be signed, then scanning it onto my thumb drive (which would cost more money), then returning to my home office to upload and email the signed documents (as I would not want to spend any more money at FedEx). In short, it's free for the first three documents per month (a limit I've yet to exceed), which saves me time and money sending signed documents to every concerned party who needs them. Also saves a few trees and paper, too.
What do you dislike?
I'm not too thrilled that I would need to pay in order to sign more than three documents a month. Thankfully, I've yet to reach that point.
Recommendations to others considering the product
Inexpensive, especially if you only need to sign documents three times or less per month. Simply scan your signature, upload it to HelloSign, then drop it onto the document in need of signing. No printers needed, no paper wasted, no trees needlessly cut down.
What business problems are you solving with the product? What benefits have you realized?
I needed to sign and email contracts and W-9s with my freelance clients. HelloSign takes care of the signature issue, saving me a trip to FedEx (I don't own a printer).
