pdfFiller scores top ratings on review platforms
It's easy to use, I do like it; but it is a little expensive, $80/year is a lot. I use it maybe once or twice per month. I think you would have more customers if it was less expensive.
Too easy to get into FONT setup and not get out and return to font specified in document. I only wanted to get the lowest priced version, not discontinue.
Wow I am so grateful
Wow I am so grateful, this service I really didn't use but one time and I was charged a second subscription. I contacted the company and they immediately refunded my account. Top notch Customer Service!!
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.
Very satisfied so far. Have not yet utilized the notary service but plan to do so. Very happy editing PDFs. My only complaint is that it's far too expensive for my needs as an individual. I can see how it would be well worth it for a business, but in my case, I will likely cancel after a month because I just can't afford it. Please consider a cheaper option for individuals &/or sole proprietors. That said, it's a great service -- far better than others I've used. Great job.
PDFfiller for contracts
I use pdf filler for anything between signing contracts and making NDAs. It's easily recognizable and has a good reputation.
The verified process and the ease of use.
It can get too expensive at times if you aren't getting discounts or special offers.
I used the free trial to compile rent due ledgers for the ************** requirement. I did not cancel on time and was charged $180 dollars. I reached out to support and ****** returned my email within minutes. I provided my information to customer service specialist ****** and he fixed the problem. There wasn't any back and forth emails. It was straight to the point. Thank you ****** for being quick and professional.
FINALLY!
ITS EXACTLY WHAT I NEEED TO GET MY BUSINESS UP AND RUNNING AGAIN AFTER BEING CLOSED DOWN. NEEDED PAPERWORK FOR LOANS AND NEEDED TO ADJUST NUBERS FOR 2019/2020. AN ABOLUTE NECESSITY FOR POST COVID FINANCES.
What do you like best?
User friendly. Can do anything I really need, from editing pdfs, splitting up and saving parts of documents, signed documents, etc.
What do you dislike?
The sign in page can be a bit wonky and hard to see if you're signed in. If you've been signed out and start uploading it puts you into the trial mode, and once you figure out whats going on you have to start over.
What problems are you solving with the product? What benefits have you realized?
Signing documents is really important for me, which is the biggest benefit. But the ability to edit and fill out pdf documents has been wonderful as well.
