The Earnings Analyzer helps you read your Amazon Product Earnings Report. It shows totals by category, how many sales vs returns, your average commission per sale, and which rows it couldn't match to a known category.
The Earnings Audit does something different: it compares what you were paid against the applicable commission rate for each line item and flags possible discrepancies.
It is a CSV file you can download from Amazon Associates that shows every commissionable transaction: product, category, sale price, quantity, referral fee (commission), rate applied, and date. The AMZLOSS analyzer reads that file and summarizes it for you.
The analyzer helps you understand your report — totals by category, return rates, commission averages.

Run the analyzer first to understand your data, then the audit to verify it.
