There is no ‘repeat buyer’ dashboard or report. We track these buyers by simply downloading the [order history|https://sellercentral.amazon.com/gp/transactions/orderPickup.html/ref=ag_orderrpt_dnav_myo_] and doing a simple pivot table. In less than a minute of excel work, we have our complete list of repeat buyers and how many orders they have placed.
We manage our demographic and order patterns by downloading these reports on a regular basis and loading it to a database. This allows us to closely monitor our metrics; more detailed than what is provided within Seller Central. We combine order, shipping/tracking and payments to get a more clear picture of what is happening with our business.
