So far I absolutely love it. I figured out that I can have my clients sign things electronically through this and I swear that alone makes it worth its weight in gold!

It takes a minute to get use to but I think I'm getting it. Trying to use to send files to the government.
I was trying to figure out how to just save a pdf filled out.... there are so many pop up windows.

Easy Auto-Renew Subscription Refund
Like most sites that offer small services with yearly or monthly subscriptions, you most likely run into the "auto renew subscription" headache. While it is frustrating (as this happened to me with PDFfiller), it is always nice to have a little forgiveness. Before I disputed the transaction with my bank I "calmly" contacted PDFfiller support asking if I could be refunded for this un-consented transaction of $72. It only took 5 mins with customer support to give me a full refund. And for that hasty/easy relief they gave me (as well as a refund with no questions asked) I give them 5 stars. Also, not to mention, it is a great PDF filling software.

Its great and affordable. There are lots of little features I like. The e-sign is the best feature as my business is online and having authorization forms for the clients to sign.

Thus far this has been a great experience. It provides all of the forms that I could ever use and it has a docusign version that makes it easy to connect with the clients I am serving.

I am a relatively new user to pdffiller, but have found the platform user friendly and does exactly what I need it to. Helping me modernise a lot of statutory requirements for e-signatures and template creations.
When I experienced issues loading documents due to permissions through my work network, the support team at pdffiller responded quickly and continued assisting myself and co-ordinated with my employers IT support function to resolve it within 24 hours, allowing me to get on with my job.

This has been a great for filling my forms
This has been a great help with the forms I am currently working with. It does sometimes freeze but usually if I close the program and reopen, it works fine.
