When you go out of stock on Amazon, you aren't just losing today's sales. You are losing ranking, historical data, and customer trust. Once you replenish, you often have to spend thousands in PPC just to get back to where you were. At JMB Solutions, we treat stockouts as a preventable disease. Our prevention strategy includes: The "Lead Time" Buffer: We don't calculate shipping based on "best-case scenarios." We build in safety margins for customs, port delays, and trucking.
