It's very intuitive. When doing a multi-sign document, the colors make the different signers stand out. It's a much better experience than Adobe Sign which is very confusing.

We used the trial version to test this service out, it has worked really well for us and our youth baseball association. I am glad the trial version let me use it almost exactly like the paid version. Many other providers do not let the trial version be used that way. This is why we chose airSlate SignNow!! Thank-you!!
