pdfFiller scores top ratings on review platforms
When I first signed up, I only wanted a personal account. They system did not provide me with an option to choose, that I could see, between accounts. It automatically signed me up for professional and now I have to jump through a few hoops to cancel the pro and sign up for personal.
This program was a lifesaver while trying to apply for jobs and fill out rental applications out of state. I'm sure there are free ones out there but this was so easy to use and had every feature I needed. It has truly been invaluable. I had one document that wouldn't open and with one click I had it sent off to tech support who replied within 2 minutes and I was filling it out in under 10 minutes. Very happy and would recommend to anyone!
I'm so glad that I found with service. It makes getting paperwork completed without leaving the office. I signed up to use if for free. You only get a couple of free times to use the service. Then you have to pay for your account. I paid for it mainly because I can use it anytime I want to. No Stress of whether or not it's going to work or be correct. It Always Is Both.
PDFfiller has been an excellent tool for both personal and professional uses. I especially like that I can send documents and get a confirmation receipt once the recipient downloads it.
It's not as intuitive as I hoped to use the mobile apps, and it seems there are many steps to doing the main process which led me to purchase PSF filler--uploading and emailing HIPAA related documents that I've photographed. I'm sure there'll be a learning curve, however, so I am still hopeful.
With two helpful and timely chat guidance, I was able to resolve my problems with scanning and uploading photographed documents quickly. I still wish the mobile app allowed me to rename the document so that I wouldn't have to fiddle with it later in the browser app, but am happy with many other features at this point.
I wish there was a way to access a blank 2019 W-2 form. The first form came up as 2019, but the only way I found to create 2019 for the other employees was to duplicate that first one and modify for the additional person. If not for that quirk, I would have given 5 stars.
It's very easy to edit the documents…
