Basically, the company’s bonuses are visible but impossible to receive, because the company has an unwritten rule that when a customer assigned to you has outstanding payments, your bonus will not be paid until you clear the customer’s debt in full.
Also, because customers of employees who previously left the same department are assigned to you not long after you join the company, many unexplained outstanding payments end up being counted against you. Then your bonus gets held up, and you have to start chasing payments from customers you never personally handled, urging them to pay.
And, due to what seems to be an issue at some level of the company or with the system, customers’ long-overdue payments often suddenly come to light, with you being told that the customer failed to pay an invoice from a particular year and month. The customer has long forgotten about it and therefore will not acknowledge it.
In the end, if you want to clear the balance, you can only pay out of your own pocket.
