Price increases get called a win early. Bookings hold for a quarter, the announcement goes out, and nobody goes back to the numbers. Then discounting creeps back, volume softens in segments that were never modeled, and churn shows up two renewals later. This is a walkthrough of one price change from hypothesis to six-month review. It covers the model finance built before launch, the leading indicators it tracked every week, the assumption that turned out wrong, and how the result was reported to leadership when the answer was mixed. Bring your next pricing decision with you. You’ll leave with the checks to run before launch and again at six months. Key takeaways: - What to model before a price change goes live, and which assumptions break first - The leading indicators that show whether a price change is holding - How to report a mixed result and keep your seat at the next pricing decision
