What do you like best?
I love that I can alter a pdf with just about anything. I can also send forms to my clients to e-sign through a secure site. Often I use it to sign documents that are sent to me as well.
What do you dislike?
The only drawback that I have is if I upload a document and want to use it for different customers, it doesn't save each one individually.
Recommendations to others considering the product:
Buy it!
What problems are you solving with the product? What benefits have you realized?
If I can't get a real-life e-signature I turn to PDFfiller to get the job done. My clients benefit from the secure site when I send sensitive documents to them.

I had an occasion to need a form filler on a ***. 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 dont need a *** form filler on an ongoing basis. When I saw the annual charge on my ****** 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 *** form filler I will absolutely buy PDFfiller. It works and they believe in customer support. A rarity today.

It's user friendly and I'm figuring it out as I go... just a bit of support with downloading to my google drive and figuring out why/when to use the link would be great.

I had an issue and emailed the company and not only did 2 different people respond immediately they resolved my issue within a few hours of me sending the email. I’ve never seen that quick of a response before. Very impressive.

I was able to find any form that I needed to fill out. PdFiller was instrumental in helping me fill out additional tax forms needed to file my taxes. All the forms were there already! There's even away to have your documents sent/mailed to the intended party! I wish there was a way I could have a subscription for a much lower amount that's based on my usage. Right now the price point is decent for a person that uses it frequently like multiple times a day.
