What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
This program is awesome. A little difficult to look up forms at times - but overall experience was fantastic and the finished product looks clean and professional.

Good site/product. The only thing that bothers me is that is seems like when you email from the application (rather than save to your computer and forward) it seemingly wants the recipient to "buy" PDFfiller in order to print or use the pdf. I might have this wrong based on a hurried initial exchange.

This is my first attempt at using your system but so far so good. I'll answer other surveys later after I have had some experience with the system.
It takes a little experience to use the system easily. You could use more instructions. Perhaps a start guide on how to perform various manuevers.

The site is a bit slow, and often will freeze during filling. Otherwise it is well worth the $72.00 I paid although it was supposed to be a free trial for 30 days.

I loved using the program. It helped on saving paper while allowing to update documents without having to print, use white out, and scan the updated document. It was really the only feature I used, but i know there was so much more to the program. I would love if they created a pay option that was cheaper than basic or reduced the price of basic for those of us who just need it for one or two functions. It was very easy to use and i wish i needed it for other things. Overall still a great program and i would recommend it to anyone. I am only giving it 4 stars due to me just not needing it for a whole lot.

IT'S BETTER THAN DOCUSIGN
I like that you can send to other to sign just like docusign. You can also fill in the blanks. You can share the info and even print. Also is not too pricey.
What I don't like is, when I send to multiple signers anyone can sign even on my signature. I wish they'd allow set signatures per person so that folks won't get confused .
2017-11-14
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.
2022-12-15

How do you find the sum of a log?
A useful property of logarithms states that the logarithm of a product of two quantities is the sum of the logarithms of the two factors. In symbols, logo(XY)=logo(x)+logo(y). (x y) = log b (x) + log b
Can you add logarithms?
Logs of the same base can be added together by multiplying their arguments: log(XY) = log(x) + log(y). They can be subtracted by dividing the arguments: log(x/y) = log(x) — log(y).
What is the formula for log a log B?
The identities of logarithms can be used to approximate large numbers. Note that logo(a) + logo(c) = logo(ac), where a, b, and c are arbitrary constants.
What is a log divided by a log?
Division. The rule when you divide two values with the same base is to subtract the exponents. Therefore, the rule for division is to subtract the logarithms. The log of a quotient is the difference of the logs.
What is the log rule?
The logarithm of an exponential number is the exponent times the logarithm of the base. The logarithm of a number that is equal to its base is just 1. Rule 6: Log of Exponent Rule. The logarithm of an exponential number where its base is the same as the base of the log equals the exponent.
