i am very surprised at how easy it is to retrieve and add new pdf's to my account. I originally paid for pdfiller because i wanted to send in a release of liability to the dmv. 1 year later and I am now using it for court paper work and have downloaded many forms i can fill out any time I want. Thanks. I am very happy and surprised at this application. I am glad i didn't cancel my monthly payments to pdfiller.

Great support from the team, especially Kara
Over two days I talked to several agents. Kara was able, with great patience and time commitment, to solve my problem. Anything I have paid for the program and year subscription was was worth the service I got. I hope she is recognized as the best! Thanks to the program but most of all to her. Great job!

What do you like best?
I like to be able to upload multiple documents and then have the ability to rearrange them if needed, or remove, or even add to my entire document.
What do you dislike?
I do not like that the desktop extention frequently has errors, and continues to lag. I also do not like that the fax portion is uncustomizable.
What problems are you solving with the product? What benefits have you realized?
It helps me to add or remove specific line items, which I do not want others to see. It also allows us to add pictures to the PDF documents, such as signatures, and or stamps for notary.

this is the best product I could find…
this is the best product I could find for converting a pdf form into something fillable. I don't need to use this regularly so better if you offered a annual usage limit package- say 12 uses a year for $12.00- which seems fair and reasonable to you and the customer.

Quick sign up, User friendly for beginners and love the functionality!!
What made my experience great is that it was simple and easy to use, I had only used docusign once before and decided to try pdfFiller for some court papers that needed electronically signed immediately. It is super user friendly. Great pricing after the 30 day free trial. But my favorite part is the set up and how many different things you can easily do!!!!

How do you find the summation?
To find the sum of an arithmetic sequence, start by identifying the first and last number in the sequence. Then, add those numbers together and divide the sum by 2. Finally, multiply that number by the total number of terms in the sequence to find the sum.
How do you calculate Sigma sum?
i=3. Ii + 1 = 34 + 45 + 56. I=1. I(i+1) = 1×2 + 2Ã3 + 3Ã4 = 20. N=1. (2n+1) = 3 + 5 + 7 + 9 = 24. And we can use other letters, here we use i and sum up i A (i+1), going from 1 to 3: n=1. N2 = 12 + 22 + 32 + 42 = 30. We can add up the first four terms in the sequence 2n+1:
