AWESOME program but too expensive AWESOME program, but the monthly cost is WAY too high. Should charge customers a more affordable price of $10/month. And stop trying to force us to pay for a whole year up front -- what if I don't need it for an entire year? Fantastic features, easy to learn, a pleasure to use. Just TOO EXPENSIVE.

Perfect Software for Small Business I use this software for my home inspection business to create required insurance reports and include images. It allows me to upload the required insurance form, edit it and add images for the required mitigation and four-point inspection reports. I love that I am able to save my reports, reuse them by editing as needed and organize them in the straightforward filing system. Excellent value for all of the features offered. Easy to use and manage organization. Love the FAX feature, signature, editing and capacity to upload images. Flash feature for uploading images. Settings have to be set and sometimes reset themselves. I use this feature everytime and sometimes the software freezes.

Fill PDF easily Filler software for life with the best features available to fill out pdf documents anywhere and anytime. The google docs addon save me a lot of time to fill out pdf's online and sending is easy after editing. Easy to use cloud based pdf editor which enhance productivity while I am working. They don't have all language support. They should add more language support.

What an awesome product. We use accord forms so often in this office that it is nice to have help! We like that most accord forms we use are already available from the site, but more so than that, the fact that we can upload our own documents as well. When you have to generate 150 certificates for one client, all different, this program makes that process seamless. The site runs very well, have not had to deal with freezing issues or losing extensive work because it didn't save, the site always saves my work for me. We just couldn't be more happy with the service. There is not a lot that we do not like about the program, but one thing sticks out for sure. If one of my agents is logged on to the site and another agent logs in, the first agent will usually be kicked off. This was not really even an issue since the system always saved the agents work, and all of my agents will announce now that they are logging in.

What do you like best? It has the main features that I'm looking for: I can upload a pdf, add text, remove text, blackout text, etc. It also allows e-signatures. What do you dislike? The process to download files is a little tedious. You have to single-click on the file from a list, then the program takes you to a new page to rename and choose the download location. But if you accidentally double-click on the file, the file will open instead. I've been using this program for years and it still takes me way too long to download a file. What problems are you solving with the product? What benefits have you realized? I use pdfFiller to fill out forms for work. I used to have to print these forms, complete them by hand, then scan them and shred them. With this program we get to eliminate the use of paper and save time.

This program is a life saver. Only that I wish I was able to push the numbers over to the side a bit and make them a little bolder. I pray that they don't see the imperfections and I can get my loan approved. Thanks for the help pdffiller.
