It's pretty good, but some repeat items don't load, and a couple times it would not let me add a 3rd line in a box. It would be nice if columns of numbers could add up.

I was a little disappointed when i realized it was $20.00 a month on month to month plan. i intend to cancel after the cycle has ended.
Other then that i have been very satisfied.

I had difficult printing what i had written on a PDF. Although customer service was EXELLENT I still could not fully implement their detailed instructions.

I had a very complicated question pertaining to a credit card charge, (I didn't know which account within our company had incurred the charge, and therefore, couldn't track down a receipt) **** helped me reverse engineer the charge to find out where it came from. My company provides Customer Support for the Video Gaming industry, so I know the value of a positive CS experience. Way to Go, ****!

This PDF filler works like a charm
This PDF filler works like a charm. Comes in handy when you need it. Nice to have on hand. Price could be cheaper as it's not something that's needed often

I mislead them on my intentions for the service level that I required. Once I brought it to their attention, I answered 3 questions; and the matter was immediately resolved. Outstanding customer service comms. !!!

Unparalleled time-efficiency
In contrast to lots of our competitors, we value your time and want you to be as productive as you can. Generate templates for your most often utilized documents to prevent retyping data, fill out up to 1,000 uniform documents at a time, or extract information from forms in bulk.

Is form stack confidential?
Privacy Policy We take the privacy of your forms and data very seriously. Your form data will never be sold or distributed to a 3rd party, and we will never view or access your data unless you specifically request it for support reasons.
How secure is form stack?
All data and documents stored in Form stack are protected with powerful encryption. No merged data is saved in our system. All information is sent over an SSL (Secure Sockets Layer) connection to prevent data breaches and man-in-the-middle attacks.
Are online forms safe?
Unfortunately, securing a Web page with an SSL Certificate is often where the security ends, but it shouldn't. Security is most likely to break down after the form information is securely transmitted to the server, where it is completely invisible to the user.
How do I password protect a form?
You can password protect your forms if you would like to prevent just anyone from accessing them. Only those with the password you set will be able to view, fill out, and submit the form. To do this go to Settings > Security > Choose 'Password' from the 'Form Password' dropdown.
Is form stack encrypted?
Form stack Documents uses 256-bit and TLS encryption by default to protect your documents. There is no need to enable or set up encryption yourself. If you need to generate documents that contain healthcare data, you can add an extra layer of protection with our HIPAA compliance options.
How does form stack store data?
Maintain your peace of mind Any information stored in Form stack Documents is encrypted using 256-bit encryption. By default, we do not save merged data in our system. Any information that is used to populate your documents is immediately deleted after the merge happens.
