Why do my numbers seem different across the various seller reports?
You might notice subtle differences across reports in your seller account, including Business Reports, Order Reports, Payments, Performance Reports, and so on. While some reports appear similar, each one uses a slightly different data set to help you understand different aspects of your account.
Here are several ways similar reports can differ:
Business Reports includes cancelled orders, while Payments does not.
Payments includes Amazon Fees, while Business Reports does not.
Business Reports By ASIN and Order Reports in Orders include all orders placed during a certain time period, regardless of settlement status. Payments only shows orders that have shipped.
Seller Performance in Business Reports By Date shows refunds according to the refund date. For example, when a unit is ordered in September and is refunded in October, the refund counts towards October.
Customer Metrics shows refunds according to the order date. For example, when a unit is ordered in September and is refunded in October, the refund counts towards September.
