This is a good way to show everyone that you have a limited amount of time and resources and that a company can't deliver everything in a reasonable amount of time. We do something similar with our product management process but instead of customers buying features we have internal stakeholders purchase them.

We'll take some percentage of a release and set feature "prices" based on a swag of effort. Then we allocate a percentage of release time as "dollars" to the stakeholders. We just keep track of it manually since it's all internal but we've found the process works nicely for feature prioritization.
