A papermaking machine unit has a measurement system which provides performance data. The machine supplier sells maintenance and process support services at a price determined by the level of performance of the machine within a given time period. The supplier and the customer agree on a desired performance level, and the charge to the customer is set at a fixed price plus a variable price based on performance level. The amount paid to the supplier will be greater than the fixed price if performance is greater than the desired level, and will be less than the fixed price if performance is less than the desired level.
