When we speak of buyer profiles or personas, we are often referring to the role someone plays at a company, what pain points they have, and what challenges our solutions might solve for them. With pricing profiles, you look at clusters of your market and see what common needs these clusters have and then understand what willingness-to-pay parameters they exhibit.
There is a fantastic article by Madhavan Ramanujam and Georg Tack of Simon-Kucher & Partners called Your New Hit Product Might Be Underpriced (which is also an excerpt from their very insightful book “Monetizing Innovation”) that discusses the importance of having the “willingness-to-pay” conversations very early on in the product innovation cycle.
