I used it now for 2 forms. I like that It does everything for me..saves the document, converts to another format if I need it and easy to email out or print.

Excellent service and customer service! Disappointed however that the maximum number of pages allowable is 150. I'm working with much larger documents. The rest is great though.

For a new customer who has only used this program for a short time, It's a bit confusing to find all the necessary information. I am learning, but it's taken some navigation, and I haven't used the help line, because I don't even know the right questions to ask.

much better than trying to fill out…
much better than trying to fill out some of these forms by hand or create a form from image using something like Adobe acrobat. Only problem was you should probaby do better quality control on the forms provided. I found your Chapter 7 petition package to be unusable (all or most of the checkboxes use the same variable i.e., check one and you check them all.

I mistakenly did not cancel the trial…
I mistakenly did not cancel the trial period and was billed for a year's subscription. When I wrote to the support team, they immediately cancelled the subscription with a full refund. Even though the mistake had been mine, there was no lengthy questioning about how it happened or extra surcharges or the like. I very much appreciated their professionalism in meeting my needs.

Helpful.
I liked that is had documents on hand that I needed and was able to manipulated them and submit them for the purpose I needed them for.
It was a little tricky to use at first, but quickly figured it out.

I reviewed this software for my company…
I reviewed this software for my company (we historically use another product) for function and usability. It is significantly more user friendly than the others that do similar functions. What makes this a good decision is the cost and the support. It costs a third of the software we currently use and when I experienced a problem (on the weekend) I had (professional and personal) support online in less than a minute. Very satisfied.

An invaluable resource for filling out forms. Incredibly fast customer service that is exceptional in handling your needs. In this day and age when companies can treat you like a number, it is nice to know that PDF Filler is not one of them. They treat their customers with respect and attention, satisfying their needs quickly and efficiently. More companies could learn from them on how to conduct business.
