Look no further than pdfFiller! As a person 70+ years old, new programs are usually a challenge for me. However this was not the case with pdfFiller, it was so easy to click on the area and type and being able to alter the text size to fit was a bonus. I highly recommend this program and can vouch for customer support who are there to help.

Was able to use site, but site is not mobile-friendly I tried using this site on my mobile phone and would recommend only using a PC; the site is not mobile friendly. Otherwise after some effort I was able to upload, electronically sign, and send a PDF document.

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.
