So far it has worked for what I need. I wish there was a better price for non profit corporations. AZ Exotic Bird Rescue, Inc. is a 501c3 charity but I had to buy myself because of the cost.

I like that I can quickly sign something without printing and scanning signing and scanning again. I can send this out right from here via my email, haven't checked Gmail records yet, but if they've been recorded there, I think I will use this app for years to come.

This service was extremely helpful when I was in a pinch for an assignment for work! Loved being able to combine multiple PDF's into one cohesive document, as well as edit, add text, and highlight on my existing PDF. Easy to use and user-friendly!

Besides being a great product Support is Outstanding Besides being a great product, I would like to express how good the support is.I worked with Sam for over an hour, He went way above and beyond helping me with my Zapier Integration. Most companies would have just said that is "out of scope" Or "not my problem" Not these guys, they logged into my computer and dove deep into it and fixed my problem. Also keep in mind, I am only on a basic plan and they treated me like I was spending $1000's of dollars with them.

Pdffiller, great if you fall into the niche I love being able to merge several photos into one pdf without having to worry about awful formatting. It's pleasant to use and it gives good results. This product is not actually free (in my experience) I would appreciate free trials without the need for credit card info.
