great except when i want to email something sometimes the other party can't view it as a pdf. i dont get why. I want an option to save my new document in my own hard drive but can't figure out how to other than emailing it to myself. add that option or help me find it.

In my line of work (payroll) it's a lot easier to be able to fill out some of the paperwork that I need to send to employees/managers and attach it via email instead of handwriting it and scan it to them.

Very good user friendly software. The only negative was the advertised payment of showing a monthly amount but the company deducted the whole 12 months in one lump sum.

PDF Filler is great. I started with the free trial, then went to the pro, but now I've switched to Basic. I got this for signing contracts on buying and selling my home. Awesome!

This was a great program This was a great program. I just don't use it enough to justify paying annually. I wish there was a charge per file option.

Excellent Saves me from taking up so much of my memory on the office computers. Easy access and you can edit your documents anytime. It is very handy and you can save your work plus be able to edit your documents at a later time.... need to be able to tab from filler boxes and be able to automatically type in the boxes without having to add text boxes

CUSTOMER SERVICE THE WAY IT SHOULD BE!! I was using pdfFiller to edit divorce documents I downloaded from the Court Clerks website. Being able to edit these documents was going to save me around $500 in attorney fees. When it was time to save and print I was directed to purchase the subscription. There are 2 options... you can pay for the whole year at once (paying $8 per month) or you can pay $20 per month and be billed each month. I accidentally authorized the whole year @$96 to be charged to my debit card. This was not my intention but I knew it was going to be such a hassle to get them to refund my money that had already cleared only to spend $20 with them. I contacted support thru the chat option anyway and found I was very wrong in my assumption. I was connected to Ray who in less than 5 minutes had refunded the difference of $76 back to my card and was inquiring if there was anything else I needed help with. This is how customer service should be and very rarely do I experience anyone who should bear the title of a customer service representative. THANK YOU RAY FOR YOUR HELP AND PDFFILLER FOR HIRING COMPETANT ENJOYABLE PEOPLE TO DEAL WITH YOUR CUSTOMERS.

What do you like best? I like that PDF Filler is user friendly and it's easy to navigate. I love that I can create a template and then just fill in what I need to for each customer and we can send them a form digitally for them to sign. What do you dislike? Occasionally customer's take a while to sign a document because they think it is spam. Recommendations to others considering the product: Easy to use program. Creat templates you can use over and over which is great! What problems are you solving with the product? What benefits have you realized? It's a fast, easy way to be able to send documents for our customers to sign without having to sign in person. We have also been able to streamline some of our processes better by using PDF Filler to create documents.
