I have used the free trial twice. When I signed up for a $6 one month personal subscription I was billed $20USD. I have sent an email about this and hope to have it resolved.

The best part is that it automatically "carbon copies" to other pages if they require the same information (ex: 1099 tax doc). I've used other PDF generating programs and you have to manually fill in each page. This is such a time-saver and seems like an obvious feature that would be part of any PDF program. I guess this is what makes PDFfiller a greater product than the competition!

I find it very helpful, but sometimes I can't find the form I have completed and I have to start over when I need to make changes. Or it wont allow me to make changes.

A little confusing at first but once we got the hang of things it was okay. I wish there were more options for fonts and placement of wording and graphics but overall okay

Easy to use rich functions! I was able to edit buldan.store martial arts catalogues in the absense of the designer - recognizing and chaning fonts, prices, layouts. Saved me time editing designer catalogues. Thank You, Daniel

I have noticed that this is I have noticed that, although this subreddit has 1,000,020 readers, I am not receiving 1,000,020 upvotes on my posts. I'm not sure if this is being done intentionally or if these "friends" are forgetting to click 'upvote'. Either way, I've had enough. I have compiled a spreadsheet of individuals who have "forgotten" to upvote my most recent posts. After 2 consecutive strikes, your name is automatically highlighted (shown in red) and I am immediately notified. 3 consecutive strikes and you can expect an in-person "consultation". Think about your actions.

Excellent service. Website is easy to navigate and the forms available are excellent. In my case, even though the website is user friendly, I think a short webinar to familiarize customers would be of great benefit. I would certainly recommend PDFiler to others.
