Seems user friendly for the most part. It would be nice if the documents could be automatically opened in Drive without all of the signing in process each time

Easy to use
I couldn't find what I was looking for on the CRA site and this popped up in my search. I have used it before for Real Estate forms. I didn't know I could use it for CRA forms too.
I love how easy it is to use.

Easy to use, great price
Easy to use, fantastic tool for editing pdfs and drafting up invoices. I work from home and the interface is nice and easy and straightforward, especially when there's no one around to ask other than myself! A very reasonable price too. I'm very happy with the service provided here.

Easy and Superb!
I love how easy pdfFiller is to use. Also, the results are amazing! I uploaded a signature that looked great from my computer but I couldn't get the page colour right. PdfFiller fixed the colour so that the background of the upload and the entire document were identical. I didn't need to try fixing it myself!

I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed.
I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature.
I use this all the time in my business and I would recommend it.
