So easy to use not being rejected
My bank required my signature not an electronic signature. Maybe if I used my signature on pdf format I will try that next time.

One time using pdfFiller the first time…
One time using pdfFiller the first time saved me time doing a very basic operation (checking off fields when I was entering information from forms into another program). I have used the other program for over 15 years but recently moved from a PC to MacBook Pro. The program for Mac is harder to use than the PC product. I have spent too much time and frustration with that program. After one use, I had to spend much less time with little frustration. I hope it continues as I using pdfFiller

The service was great and really…
The service was great and really useful! I've used it for the past year- I just didnt need it and couldn't afford it this year- the reason I'm giving 5 stars is because when I went to cancel it within a month of by mistake letting it renew- they (Jerome in the chatbox) were SOOOO AMAZING and helpful! With so many companies they completely dehumanize you and fight for ages when you try to cancel. It has given me immense respect for this company that they were kind and helpful!

What do you like best?
That it looks professional, it is easy to use, and there are so many common templates to use which are always necessary, especially for a small business owner.
What do you dislike?
That it is always such a process to sign in if I am not at my home computer.
What problems is the product solving and how is that benefiting you?
It allows me to complete my forms needed in a timely manner and saving time for me is ALWAYS beneficial. I am more productive.
Title for your review:
Excellent site for completing and sending important professional looking documents.

Smooth fillable process
Smooth fillable process. It's just the end of the process, saving the document and accessing it that I still need to get used to. I don't feel too comfortable as I feel like my documents are not easily accessible if I forget my password. I guess it's a matter of getting used to. Also is there a charge sometime in the future for this?

I had difficult printing what i had written on a PDF. Although customer service was EXELLENT I still could not fully implement their detailed instructions.

I think you should ask me this again in…
I think you should ask me this again in another month. I'm very new to using this, and far from computer literate, but so far I am finding it very easy & extremely useful.
Thank you!
