What running a machine does today
Jobs sent to your machine are billed to the shared pool at your SKU's catalogue price. When a job finishes, 70% of what that job actually cost is recorded as owed to your machine. The rest stays in the pool — it is not a fee you pay.
Nothing is paid automatically. There is no transfer on this platform: an operator pays what is owed by hand and records it. Until that happens the figure is a debt to you, not a balance you hold and not something you can withdraw here.
