The FBA Sales Lift tool may occasionally appear on the Business Reports page of your Seller Central account. This page will give you information on when and how this tool may appear, as well as how the data is gathered.
Occasionally, on your Business Reports page you may see the FBA Sales Lift tool. This tool will appear when we have data that shows a comparison of your unit sales on products that you have fulfilled both through FBA and also your own fulfillment methods.
Not all products may appear in the FBA Sales Lift tool. We only include products
where we can make a comparison across equivalent and meaningful time periods. At
least 28 days of data is required in each fulfillment channel. As this tool only
evaluates limited time periods in order to make the most relevant comparison,
the data within the FBA Sales Lift tool may not match your total sales data.
We look at the prior 12 months of your sales data to find products that have been in stock through both FBA and self-fulfilled. Product-by-product we analyze equal amounts of time, and compare FBA unit sales with self-fulfilled unit sales during that time period to produce a FBA Sales Lift. The total FBA Sales Lift percentage at the left represents average daily sales lift of all the individual products. To the right you can see select examples.
For example, if you self-fulfill a product for 40 days and sold 100 units and then converted that same product to FBA and you sold 130 units in the 40 days since change in fulfillment the FBA Sales Lift tool will show that your product had 30 percent FBA sales lift.
