Perceived quality is what a customer is willing to pay for. Take a car, for example. Power and velocity are a proxy of quality by clients. Quality and price of a car are strongly correlated.

Take engineering software then. Simulation accuracy and velocity are two major benefits clients are looking for. The first is how much the simulation fits the reality, the latter is how the product design time can be shortened.

For some reasons the software price continue is not correlated to those qualities and continue to be linked to technical features only. Linking price and the perceived value, makes easy converting software advantages into a premium price.
