Everything works
Everything works, you do not require me to pay for continually using the service and my signatures and information are saved in the site. 100% would recommend to others.

I am not the most skilled with modern technology. As a startup NFP we don’t have the financial capacity to either hire, or contract with an accounting professional to prepare our year end 990s. I personally took it upon myself to do the necessary paperwork. I kept losing my work, and did not know how to save it without Word. I stumbled upon pdfFiller and decided to sign up. The retrieval and storage of my docs (either completed or still being worked on) is so simple now that even I can do it! The work has become easier thanks to pdfFiller. Thank you.

I just started using it today
I just started using it today. So far, I am very happy with it. I was able to use the draw feature to sign where I needed to, how I wanted to without using the "sign" feature.

Intuitive and easy to use
Easily and quickly fill pdfs with this simple software, just be aware there is no free option other than a 30-day trial.
This software is really straightforward and easy to use. I find it intuitive and am able to edit pdfs quickly and painlessly. Adding a signature is really easy as well.
I did the free trial of this software and even though I was impressed, I didn't end up purchasing the monthly subscription due to my needs. There are options out there that are free, although they're definitely inferior in terms of functionality and user interface. So I think the cost (even though it is reasonable) ended up being not worth it for me specifically in the end. Other than that, I had no problems with the software and would recommend it to someone who uses pdf software frequently.

Great service. I thought my subscription had expired but the tech support hooked me back up in a jiffy! I prefer to use PDFfiller program rather than the Acrobat Reader DC program. I will always renew my subscription in the future.

Student charged 115€ despite cancelling free trial – very disappointed
I am extremely disappointed with my experience on pdffiller. I had signed up for the free trial, made sure to cancel it before the end, and yet I was still charged €115.20 for a full annual subscription without my consent.
I am a student, and this unexpected charge has pushed my bank account into overdraft, causing me financial stress. I never agreed to any paid subscription, and when I log into my account, it still shows as “free”, proving that I had cancelled on time.
After checking Trustpilot, I realized that many other customers are facing the exact same issue — this seems to be a recurring problem.
I have contacted customer support and sincerely hope they will resolve this quickly and refund me. But this situation is really unfair and unacceptable.

How do you block statistics?
With a randomized block design, the experimenter divides subjects into subgroups called blocks, such that the variability within blocks is less than the variability between blocks. Then, subjects within each block are randomly assigned to treatment conditions.
What is blocking variable in statistics?
blocking variable. A categorization variable for information within a dataset that is used to control, test, or manipulate the distribution and statistical results. These variables should be observed, reliable, and unchanging. For example, a dataset can be blocked based on name, date, race or gender.
What is a block in statistics?
In the statistical theory of the design of experiments, blocking is the arranging of experimental units in groups (blocks) that are similar to one another. Typically, a blocking factor is a source of variability that is not of primary interest to the experimenter.
What is variable block?
Variables Blocks are one of the eight categories of Scratch blocks. They are color-coded orange (for variables) and red (for lists), and are used to hold values and strings.
Why is blocking used in an experiment?
When we can control nuisance factors, an important technique known as blocking can be used to reduce or eliminate the contribution to experimental error contributed by nuisance factors. The analysis of the experiment will focus on the effect of varying levels of the primary factor within each block of the experiment.
What is a blocking variable in an ANOVA?
The one-way ANOVA Test with Blocking is used to test the equality of three or more means from dependent populations. The 'Blocking' variable is a variable that contributes to the total variation but is not itself the focus of the study — it is often called a 'nuisance' variable.
What is a block sample?
Block sampling is a sampling technique used in auditing, where a sequential series of selections is made. For example, an auditor elects to use block sampling to examine customer invoices, and intends to pick 50 invoices. However, a more random selection method would do a better job of sampling the entire population.
What is blocking in an experiment?
In the statistical theory of the design of experiments, blocking is the arranging of experimental units in groups (blocks) that are similar to one another. Typically, a blocking factor is a source of variability that is not of primary interest to the experimenter.
