Haven't been able to add a blank page to the 3 page form I was working. The instructional video indicated I should see a "Pages" icon on the Edit line. I didn't.

I am strongly satisfied. Forms are very easy to make correction and automatic save feature is very very helpful. Thank you so much. Also the annual fee is extremely affordable. Five stars for sure

I like it but I still don't get the refined product I am using plus in the ad, it said "$6/month" when they charged me it was $20. How come?

What do you like best?
Customer service and support, professional
What do you dislike?
No month to month subscription plans, but the cost is reasonable
Recommendations to others considering the product:
Great service
What problems are you solving with the product? What benefits have you realized?
I ended up not using there service but felt the need to write about my experience. I had a complex need that was nearly impossible to get. I signed up for a subscription and found out later my demand couldn’t be done. Their service team granted a refund quickly without the usual hoops to jump through. They were fast, professional and capable. I plan to use them for other projects.

Love the ease of use. I would highly recommednd this product to any business person. Initially, I was hesistant because learning new software is always my dread. However, once I signed on it was so easy. Makes daily document updates and creations easy. I can always find an Accord form I needed with this as well. And edit of pdfs are no longer an avoidance. Sometimes there is a delay from screen to screen. But nothing to really complain about.

What do you like best? I like the fact pdf Fills stores and keep my documents in order! I like it's easy to use, and it comes with a fax!! I am very pleased that I can send a fax, and I am able to submit report! Also, it come with live help that is an excellent feature! What do you dislike? I dislike the wait period of 30 minute if I forget my password! The systems doesn't seem to lock in my password. I believe I have changed passwords maybe 3 times in under a year. Recommendations to others considering the product: Try it! The price is good! The service is good! I have spoke with tech support a couple of time because I got locked out because I forgot my password and made to many attempts, so that's an excellent feature! You can also send faxes, so that's good. I will look to renew my subscription again! It's a good product! What problems are you solving with the product? What benefits have you realized? Well because of pdfFiller, I can send pdf files to coworkers and present files as needed! Before pdfFiller, my pdf files were not accepted by my supervisor and staff computers, but now, I can send pdf files with no concerns using pdfFiller! With the company working from home and folks using different systems/computer it's good that pdfFiller documents are able to be received by all my coworkers!
