I would like to be able to make sub-folder with in sub-folders. I am going to have hundreds of documents/year, and that would make it easier to organize them.

Very easy system to use and user… Very easy system to use and user friendly. The only suggestion I would make is being able to scan documents and then being able to combine them into 1 pdf file not having it as a zip file.

Excellent, easy to use and saves a lot of time It has saved me time mainly and a lot of hassles in getting physical signatures. I have signed and shared documents within minutes rather than signing/scanning or mailing. If you want to save time and get your documents signed ASAP, PDFfiller is a must have software. You can use it anywhere as long as you're online and you can edit it too without any hassles. It's very affordable.

Its great and affordable. There are lots of little features I like. The e-sign is the best feature as my business is online and having authorization forms for the clients to sign.
