On the first day of use, I thought I had lost all the data I entered. I received help via a chat and verified my data was intact. This is going to be an extremely useful product for me as a consultant.

It meets my needs very well. If I could get my own fax number for less than $10/month I would add that. As it is now, I have a fax separate from this but only pay $8/month so will keep and use separately. Disappointed it was so much for the add on. Also, for the edit option. Many things to do but all as add ons. For now, I like what I can do, though.

First time, so experiencing a few problems learning your system. Need to spend time learning how to make it work best for me. Will just have to figure it out for myself.

I love that I am able to correct and hold prior to sending out my file for signature. I wish I could however have a authorization statement from the Calyx Point file to use more of there forms.

it's a little bit too expensive for me. I will not have to use it very often, maybe only once or twice a month for work, but i do require the premium package for all of the features that i need to have. so it just seems crazy to me to pay almost $200 a year for something im only going to use 24 times the whole year. other than the too high price, i think its a great program!

The form was fairly easy to alter and print. However, I did have a lot of difficulty inserting text into the box below the name of my company. I was not able to make the font different sizes for highlighted text which was even on different lines. I did not make the form the way I would have preferred but I am overall satisfied.

I think PDFfiller is a good product. They have so many features, it just take you a little while to get around. I will recommend this product to anyone.

Easy PDF
PDF filler is undoubtedly among the best software I have used for manipulating PDF documents. Easy to use, it offers many features and is less expensive than other software competitors. The only real flaw in my opinion is the lack of clarity about the free trial. The user can modify his document and only when downloading it he is asked to register with a payment method. This can be confusing and irritating if you don't know it beforehand.
easy to use
accessible from anywhere
includes many features
there are often problems with payments
there is no clarity on the 30-day free trial

Not only did I find the product acceptable, but the Customer Service was wonderful, the fast response was the most surprising. My issue was resolved in a day or so ONLINE and included a refund. Keep in mind you cannot get that type of service in person At your local store.
Kudos!!
