I need help to review my project before submitting to codecanyon

Hello

I launched a self hosted invoicing and accounting script built in dotnet core and angular yesterday on my own website but I also want to sell on codecanyon.
Could you help me if you can to review the product before to avoid wasting time on submission and getting rejected?

You can’t sell it on your own website and be an exclusive author on envato

Yes, I know that.I will not sell it as an exclusive author
