How can I improve my script?

Hello people of CodeCanyon,

So I have been trying to improve my item and make it more useful for buyers but I need your input on this. Of course, I am selling the item to people like you and I would like to know what buyers are looking for in a script like this. I made the script very simple. I want to add more features.

Do you recommend anything I can add? I will do my best to add them if I am capable.

Here is a demo of the script: https://www.beermoney.site/

Thank you,
Farris
