What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Just concerned that e-mail was sent with form. I did not want to subscribe to PDFfiller as I was trying to ensure that a form for Strikenet had been sent and received. I did not authorize $119.88 USD to be charged to my Visa. What I did approve was $170.00 for a Strikenet report. First attempt at trying to submit form as Strikenet taken over my Weather Fusion. Would request a refund of $119.88 USD as I do not intend on using PDFfiller, or please inform me on how I can get a refund. Thank You.

I like it thus far, however, there should be a discount for students, we are on a budget and this would so help. I have recommended your software to other classmates, i really like it, but somewhat pricey for my basic use.

Very Quick, saves me a lot of time. I regularly get pdf's that need to be completed and sent back. Now I can upload, fill out and return in a fraction of the time. Since the data is typed, I never get a question about what I wrote.

Obviously, the sales portion of the Web site needs clarifying, but customer support could not have been more generous and quick in solving my misunderstanding. Wish all companies did as fine a job.

It works great, but is very expensive for how often I will use it. I wish there was an option to purchase some sort of punch card or to pay per use instead of paying $20/month, which is outrageous if you are not using it daily.

I had an occasion to need a form filler… I had an occasion to need a form filler on a PDF. I found PDFfiller online and tried it with a trail. It did exactly what I had wanted and it was easy to use. I guess I forgot to cancel the trial so it did go into an annual charge. I don’t need a PDF form filler on an ongoing basis. When I saw the annual charge on my PayPal account I called immediately. I explained what happened and they immediately said they would close the account and refund my money. No hassle just very polite support person and efficient. Should I ever have an ongoing need of a PDF form filler I will absolutely buy PDFfiller. It works and they believe in customer support. A rarity today.
