This has been a life saver, because of small changes that I have to make I don't need to go and buy the 40 pack of forms, envelopes, etc. This is perfect for a small job.

OK. some limitations, like I need conditional logic, so if someone checks the Yes box for a question, then require them to fill out other fields. Need this conditional logic functionality, critical for my application. Else not sure PDFFiller will be useful to us.

What do you like best? Price is good and plenty of document options. What do you dislike? Would be great if it could integrate with your pdf documents without having to go to the website. maybe a feature where you can join or delete parts of the pdf without having to upload it to the website every time. What problems are you solving with the product? What benefits have you realized? All my PDF needs are being filled by the software

This is an absolutely AMAZING service This is an absolutely AMAZING service, the only reason I had to give 4 stars instead of 5 is due to the cost. To expect people to pay so much money (especially during the pandemic) when everyone needs to work and operate from home is unconscionable. If this service was, say, $12.99/mo. then I would most definitely pay it. However, the monthly cost is nearly three times that high, and it is not something I can afford on unemployment benefits of $235 per week. This service is amazing and efficient, but the company is not being realistic about the current cost of its services. And no, offering annual payments of $200+ is not a viable solution.

Easily Add and Delete Pages From PDFs PDFfiller has saved me a lot of time combining PDFs and adding/deleting pages. Definitely a must have software. I like that I can easily add and delete pages from PDFs. They also make it super easy to combine PDFs together. Overall, very happy with the platform. Might be nice if there was an option to upload and download to Google Drive.

Fumbling along with Adobe Acrobat or hand-writing forms was time-consuming, sloppy, and completely inefficient—especially if changes or updates were needed. We are going to continue to use pdfFiller and find additional uses for the product as our business grows.

pdfFiller saves us $100 or more each workday when you factor in employee time and supplies. The figure is probably higher than that, since the waiting time for patients not yet seen is also diminished, which keeps the patient from being frustrated and just leaving before their visit.

I needed a platform that could merge documents together, edit them, sign them, then email or fax them. Ideally, all in one. I was introduced to pdfFiller last year. So I just went and got an account for myself, and have been using pdfFiller ever since.
