There is a BL called “The New Emoloyee”. The MC is turning over a new leaf or just starting over and got a good job. He’s gay and so is the team leader he works with. I like that they already know their sexuality and the MC is trying to move forward from his past. It’s based off of a light novel, so you know it’s good. I dropped it around chapter 10 because I want to wait till it gets an official translation.

The former is more about management but it's enjoyable in itself.
Also I searched a bit and found this, never read it but looks like it matches what you want

Is there a story here that is inspirational and about business or money?
