experience good so far. just subscribed and I'm still learning my way around,but I alredy like it. Ist meeting my purpose . But I wish they had a PDF to word converter included. My only problem is that when I save it in my computer even in word I'm not able to edit it.I can only edit on PDFiller.

Just needed access to a quick fillable PDF for SOAP notes when my office management software with builtin SOAP notes crashed. It is filling a need for the moment, doubtful I will continue. It seems like a nice program but the diagram on the SOAP notes is too cumbersome to mark with the given symbols on the chart as, so far, I have seen no way to actually mark the figure on the chart with the same symbols electronically. There are some symbols available, like the check, circle and line but they are not like the ones on the actual symbol chart. If there was a more expedient way to use those same symbols I might actually be very interested in using this.

It was a little frustrating for me figuring out how to use the program. This should improve with use and guidance. It would have been helpful if I had first down loaded the "How To Guide". Thanks for a great program.

I like the professional government… I like the professional government templates available but the layout of the actual site is a little tricky to understand how everything works on it.

I used to have Adobe Acrobat DC I used to have Adobe Acrobat DC, which became too expensive for my low usage. I had then tried many alternatives and PDF Filler is the quickest to use online and PDF's are quick to edit without errors. Very comfortable. I am very satisfied.

Only ever used Adobe in the past. Found this affordable option. It is fantastic. User friendly and effective app. I applied for a rental with a heap of forms to fill out and now our family are living in it. I accidentally signed the 1year subscription. Advised that I only wanted to use it during the trial period for a purpose and happy to pay for one month. They communication was quick and on point. They summarised and actioned exactly what I requested. Only charged me $30 for the month and cancelled my future subscription. I would happily use this again. Thank you.
