Feedback of possible product

Hey there! I wanted to ask if such a product would be permitted on CodeCanyon. It’s about a support ticket system I am currently developing. It is aimed towards freelancers and people with a very small amount of customers. It’s designed in the way that clients need to login with credentials to the ticket system in order to get support.

If wanted I can host a demo on my webspace for some testing.
Actually I wanted to release it for free, but I cannot find a service similar to CodeCanyon only with the difference that you can publish free apps. But if it would be allowed here I would sell it for the lowest possible price.

Thank you for answers in advance!

Kind regards
