My project is doing this. Defined custom exceptions and globally handled it, making it way easier to explain what that code is doing.

Generally throwing the exceptions in a business logic is a bad idea and I see two reasons for that:
1. Exceptions are quite expensive from the performance point of view;
2. Exceptional situation is when you can not control something, for instance lost connection to the db or message broker, etc.
When you want to throw an exception in a business logic it most likely looks like one of many possible scenarios of the logic and in such case it can not be treated as an exception - it's an error.
How to work with errors? - You should take a look into the "Reault type" pattern
