I signed up for the free trial and was… I signed up for the free trial and was able to amend 2 documents with ease.If I had the kind of life that required me to need further amendments in this way, this service is absolutely one I would use. Thing is, I just don't, so I didn't sign up after the free trial! Had a little difficulty cancelling the subscription, but honestly - I think that was 'on me', I just wasn't entirely sure what I was doing.However, it's a great service and the company responded to my concern when the subscription fee was taken by emailing me back and confirming that they would be refunding the cost. So, I think you can trust this company.

This year with COVID-19, the difficulty of having documents signed, changing information and moving paperwork quickly has been a real challenge. With pdFiller, I have been able to address any paperwork issue that arises in an instant and then get documents back out for a new signature, or an update of information. This has saved me this year and helped me to meet all major and important timelines.
