For the first time...it is a good investment!!! Jorge S. Round Rock, TX

What do you like best?
Allows unlimited potential to edit virtually any document and send it electronically or conventionally. This software is a time saver/life saver.
What do you dislike?
The drawback. The Eraser tool. This tool could use some work as far as the shape of the tool. The option to be circular as well as the normal shape would be of great assistance when editing. A competitor of yours, sorry to mention uses an eraser too that is amazing and I have thought of switching simply for access to the editing qualities of that software. It allows for the one time purchase of their software and I would not pay monthly fees to maintain it either.
Recommendations to others considering the product:
Try out the product and use it!! See what you are missing!!
What problems are you solving with the product? What benefits have you realized?
The editor allows our office to clean up and mark up documents received in our office such as lease agreements or forms attached to a policy which either enhance or negatively impact the clients coverage from year to year. We directly not on those forms in our proposals during renewal negotiations so the client has specifically seen and reviewed how the coverage impacts their insurance needs.

What do you like best?
PDFfiller is a great way for me to pre-fill documents that I use on a regular basis for my clients. By having as many fields clearly completed as possible, transactions that may have been held up due to illegible or missing information can be processed much more quickly. Clients also appreciate not having to do as much work! I also like the fact that I can use a social media signin for PDFfiller instead of having to create a separate user ID and password. It's one less thing that I have to remember.
What do you dislike?
Sometimes, I get frustrated by the "auto-detect" feature that highlights an entire line of a form. I'd rather use the text insertion feature and place text where I want it rather than have to edit the whole line. The other frustrating thing is having to make sure you're logged out on one computer before using it on another device in the office!
Recommendations to others considering the product:
I recommend PDFfiller without hesitation, with one caveat: only one sign-in is allowed at a time per user. If you use multiple computers at your place of employment, make sure you're signed out of PDFfiller on one computer before trying to sign on with the other. It will save you some aggravation. This is especially frustrating if you use the program on a desktop and a laptop and forget to sign out of the desktop computer before bringing the laptop home to work remotely. I did do a lot of research before deciding to invest in PDFfiller, and after my due diligence was hard-pressed to find an option with all of the features that I needed and at a price point that I felt was affordable. For the money, PDFfiller is a great investment for offices looking for ease and convenience with pre-filling forms. The learning curve is not very steep, and there is a lot of functionality for adding features besides text: check/"x" in specific boxes, highlighting, erasing, etc. I have used all of those features with little to no difficulty. Erasing is a bit of a science, with some trial and error involved in determining the exact size of the eraser needed for the job. Being able to move inserted text around easily and increase or decrease the font size as needed is a very helpful feature, especially if you want to call attention to certain pieces of information or make them stand out from the rest of the document. While I have not used the signature feature very often, I have found it to be useful in the rare instances that I have needed it. I have a copy of my signature saved in PDFfiller, which makes it very easy to insert a signature field into documents. Clients also appreciate this feature as well.
What problems are you solving with the product? What benefits have you realized?
PDFfiller is making it a lot easier for me to personalize and email forms to my clients, improving their service experience and saving me time and trouble. It's a huge convenience for me and much appreciated by clients whose handwriting is less than clear! The biggest benefit to me is having a library of frequently used documents that I can pull up on the fly, make adjustments and edits to a few fields, and have a new document ready to go in a matter of minutes. I've also been able to add information in the "white spaces" of forms I have created in the past, to include client-specific text, contact information and other items.

Excellent uptime. Always processes correctly. It has increased my productivity and gives me the assurance I look for in any software. We use a softwar for processing IRS forms as a template. It always works as expected with no errors. It is quick and easy to learn. I do not have any negative comments considering this product

Stupid-Easy to use Very easy to get used to. This should be called PDF-Text for Dummies. I literally had this program up and running in less than 5 minutes of downloading and installing it. Wish it was a little cheaper. If you are not using it often it hard to justify the monthly cost. It may be better to go with the annual subscription instead of the monthly in some cases.

Might be signing up again because of the combine pdf feature you offer. Adobe couldn’t even combine my pdfs for whatever reason. I would need a slightly cheaper subscription then you offer.

Lock a closed document: Select it, choose File > Get Info, then select Locked. Lock an open document: Hold the pointer to the right of the document title, click the arrow, then select Locked.
Locking a file doesn't prevent throwing it into the Trash, but you're prompted to proceed when you do so, since you obviously locked it with a purpose. The Get Info window's Locked option prevents changes on a single Mac, and modifies the item's Finder icon.
You can easily prevent changes being made on any files or folders in Mac OS X by locking the file or folder in question. This locking capability will also prevent the file or directory from being deleted, since the Trash will not empty while a file is in a locked state.
A computer file that can be used by only a single program or process at one time is considered a locked file. All operating systems use locked files. In most cases, the purpose of locking a file is to make sure it can't be edited, moved, or deleted while it's being used, either by you or some computer process.
Select the file or folder you want to encrypt. Right-click the file or folder and click Properties. On the General tab, click the Advanced button. Check “Encrypt contents to secure data" option. Click Apply and then OK.
Open the document that you want to password protect. Select File > Info. Select Protect Document > Encrypt with Password. Note: In Excel, select Protect Workbook. In PowerPoint, select Protect Presentation. Enter a password, and select OK. Re-enter the password, and select OK.
In Windows Explorer, navigate to the folder you want to password-protect. Right-click on the folder. Select Properties from the menu. On the dialog that appears, click the General tab. Click the Advanced button, then select Encrypt content to secure data. Double-click the folder to ensure you can access it.
