This is the only app I can erase and fill-in easily so I love it. However, the signing function is glitchy so I use Docu or Adobe sign for that. Still, soooo worth it b/c of the Erase and Fill features.
When I chatted with support
When I chatted with support, I had had two different people who took the files I had been trying to merge unsuccessfully and merge them for me!!! Similarly when I had trouble with blank pages and missing pages in a merged document I found out it was because I was using Edge as my browser instead of Chrome. It would have been best if that had been in the program itself, but support really came through to help me out.
pdf filler is exactly what I needed
pdf filler is exactly what I needed! I no longer have to hand write every field, I can quickly and easily type the information. It helps make my document much neater and legible.
This is an excellent service that I would not have subscribed to, had it not been for the special low price. Your initial rate was way too high. Thank you for lowering the price. Keep it low and you'll keep me as a customer.
What do you like best?
The fact that you can make templates for repeat use. That saves me a lot of time.
What do you dislike?
The cost is a little high for what I use it for- just doing some monthly billing for a handful of clients.
What problems are you solving with the product? What benefits have you realized?
It saves me time and I have a lot of difficulties filling out insurance forms by hand as the fields are so small.
Great experience when I used it when I…
Great experience when I used it when I had to switch over to my online college classes, but unfortunately, you cannot add some special characters such as the degree sign not can I put subscripts which I need for my chemistry class, but everything was on point!
I used this one time for squares for a fundraiser and was looking forward to continuing using this service needed for a side job; however, this side job fell through. I thought I had cancelled on March 2, but must have not submitted something. I was charged today. If I could be refunded I would really appreciate it.
