Need IT help

Do any of you all know the best app to use to build a workflow? I have people at my company that don’t know who to reach out to for what problems and it gets super cluttered and people going to the wrong departments ETC. I want to know know if we can create an app that will have a few options to pick from ,from issues they are having then it follows a workflow till it finally takes them to the right number or email to contact?

I’m not Smart when it comes to IT or apps or coding , just a guy looking to help . Any recommendations???
