Insufficient stock

Questions
1

I am developing a stock management application but when the stock reaches 0 and the user tries to exit a product the stock goes into the negative
how to put a barrier when the stock reaches 0 and signal to the user that the stock is empty and that an exit is no longer possible?

Using conditions in the only when field, doesn’t help?

you may still run into issues if more than one user concurrently trigger this workflow.
