What is value-based pricing?
Instead of charging for time, you charge a share of the measurable value your work creates: more revenue, lower costs, time saved, or risk reduced. If a project is worth 60,000 to the client in its first year, a price of 9,000 is an easy decision for them — even if it would only take you 40 hours.
How to estimate the value
Ask the client in discovery: what happens if this problem is solved? How many new customers, hours saved or errors avoided? Use conservative numbers and agree on them with the client before you propose a price.
