at first it was a little frustrating and I am still having difficulty in put totals on one of the pages. How do i remove the 0, to replace my correct figure?

I feel as though I may have caused my own problem. Your service covers all the forms I need and I thank you for offering to fix my issue in such a timely manner.
cindy
The price is kind of crazy, I am a single mother of 3 and I am on a limited budget. The program itself is fantastic, but the price is hard for me to justify buying. :(

What do you like best?
The ablitiy to be able to edit documents in PDF format is great. Saving time. When we are bidding on a job i can use the form provided to us from the client. Very easy to use and has worked well ever time I have neede it. Another great feature is that the PDF filler is auto saved in your online profile... so you can take the documents with you.
What do you dislike?
some times when you go to open the PDF from my email directly... it does not up load... so then I have to down load the pdf on to my computure, open PDF fill web app then upload file..... not sure why it does this but it has happened more often lately than it did before.
Recommendations to others considering the product:
It would be great if the filler could be able to authenticate docuements, a big one for us is Bonding, When we submit a bond they require an e-bonding ( look it up) the ebond authenicates the signatures from 3 different parties and leave a digital paper trail that can be confrimed by the client. We recently had to do this and the one website mobile bonds.com has an interface that is not user freindly for set up... and we had to spend countless time with the tech on the phone for the first few bonds. If the filler is able to do this that would be great.
What problems are you solving with the product? What benefits have you realized?
Allowing us to make our bid proposals look great, avoid hand writing in documents, setting us apart from the rest. we also can share the file with my staff making it even better
Dorian Andrews
This program really provides me the opportunity to create the forms and fillable documents that can help speed up my report filling. I enjoy the different ways to sign and initial different documents that otherwise could not be sent back electronically without several steps. I also have created templates and forms for consistent reports and forms I will be using to help speed up my entries. Thank you I do enjoy the program But I only know a little about it. I wish there was a little more user friendly tutorials.
Erryn Crume
It is an amazing tool It is an amazing tool. However, it is too expensive for me right now. Maybe with an option of an annual membership of $50, I will think about keeping it. However, $30 / month I cannot afford it.
