I would prefer that the fill in templates be free of charge. The one used is great and I would hope to find another one as such. Easy to use formatting and site.

What do you like best?
The hosted forms and e-signatures are an awesome add-on
What do you dislike?
Not a big deal if you're not a developer, but the price of using their API is kind of ridiculous! $149 a month, seriously? Why don't don't you offer a reasonable smaller plan developers trying to accomplish minor things.
Recommendations to others considering the product:
Make it possible in Zapier to send contracts for signing to Send Now, looks more legitimate to clients in my opinion for signing.
What problems are you solving with the product? What benefits have you realized?
Helps me get contracts signed much quicker

It's a great service that operates smoothly and is good value for money (especially when deals are applied) compared to Adobe. I prefer the interface and the amount of options is comprehensive.

Able to change words on documents-So helpful I was unable to find a pdf editor that allowed me to change the words already provided on the forms. This has been a God send. Thank you for creating this program for people to use. The charge for using this program is a little expensive but I am extremely grateful for a 30 day trial. Thank you again.

Just what I was looking for! Just what I was looking for! Affordable. Easy to use website because it's user-friendly. I went ahead and got the year subscription because I was very satisfied. The only issue I had was enlarging my signature to use it. But that might be my own human error.

It works well in that you can fill out the form, but... It works well in that you can fill out the form, but it would be great if you could move the text box once you've started. I was unable to do that and had to start over in some cases because alignment was off.
