Preview works great for one people signing. Not so helpful for people sending. GoodSign helps businesses to make sure that when the send a contract it does get signed and they don't forget about it (GoodSign keeps reminding you to sign). It allows two different people to sign at the same time and it doesn't matter what order. The document is saved forever, securely so you don't lose it.

Well, yeah he forgot to mention Mail app (also runs on Mac) where you just click on Gray/Blue star "Sign" - and it's signed. But that's only the message right? Well - you should sign PDF before as well. Then - it's done. Don't get us wrong - I don't even check your project - which definitely deserve to exists - just saying - maybe it's not for everyone...
