I'm looking for an idea on how to do something, I selling a php script that runs on the web server and help merchants with something. Now I think that giving a 30 day trial will be great, letting the user experience with the script etc... the problem is, the script is a script (a.k.a, you can see the PHP source code).
1. What do you think about giving a 30 day trial? Can it increase the conversion rate?
2. Any method to overcome the obstacle I just stated?
