GREAT product!
Nothing negative! I draw up a lot of contracts for my job and this website makes it much easier.
This is very easy to use, the interface is very clean.
I wish there was an app to support this product. A lot of times I am on the go and I need to fill out PDFs. It would be nice to have an app.

Very helpful
The support system is excellent. I was allowed to converse with an agent within a few seconds. The agent also resolved my query immediately along with suggesting a few options. It was a very good experience.

Sign it!
In general is a very good option to fill and sign documents. I did not buy the paid version because I was in need at the moment and it worked perfect for me.
I like the easy to follow process of this software. You dont need to know how to use it. As soon as you start filling any document everything march along the way
I did not see any cons because I was able to resolve my needs with the free trial. I would hesitate to pay for this software if I need again.

What do you like best?
I love that I can fax items as well as the W-2/1099 features that are integrated into the IRS system! It makes my roles as a small business owner much easier with these tools.
What do you dislike?
I wish more features, such as sending documents for signatures, were added. Even just 1-2 documents a month would be helpful for my small business. A fax number included would also be helpful. I have been able to get a fax number for virtual faxing for much cheaper elsewhere. It would be nice to have an all in one for less than $25 a month or so.
Recommendations to others considering the product:
Great way to keep costs low while still running with the bigger companies and their larger budgets. From creating my own documents to faxing things for clients- great investment for virtual tools in your business!
What problems are you solving with the product? What benefits have you realized?
The IRS integration have helped me navigate some of the tax paperwork I need to do for my employees. The fax feature is super helpful for getting paperwork out for our clients.
