A sold-out tour can leave almost nothing on the bottom line. That is not a mistake, it is the model.

Consider an artist who has just finished a UK theatre run, ten nights, every single one sold out. Strong reviews, full rooms. Then the tour accounting comes in, and the bottom line is almost nothing.

Nothing went wrong. Nobody was ripped off. This is simply how touring economics work, and clients usually discover it the hard way. When you advise on a tour, the headline gross is the trap; the cost stack is where the money actually lives.
