What is Estimated Sales Report?

Estimated Sales Report is used for getting the list of items that are sold on amazon even though there settlement report are not yet generated. The settlement report is generated after 15 days so it is not possible to calculate profit/loss real time. Estimated Sales Report comes to rescue here. It helps to generate sales report real time.

Process for using Amazon API to generate Estimated Sales Report

  • First step is to call ReportRequest method from MWS. Start_Date and End_Date are passed as parameter. Default value is current date and time. This returns the data from where the last settlement report was generated. This method will return the ReportRequestId List.
  • Second step is to call the GetReportRequestList method recursively until the ReportRequestId field has status “_DONE_”. When we get the matched status for the ReportRequestId, it returns the List of GeneratedReportId.
  • Check that the GeneratedReportId is present in our system to avoid duplicate entry and use GetReportRequest method to generate the report. If the GeneratedReportId is not present in the system we use the GetReportRequest and we  pass GeneratedReportId as the parameter. It returns data in XML format.
  • Deserialize the output to get desired output. Use that data and save it in the system. Developers allow this function to run automatically every hour to receive latest data regularly. Profit/loss report thus generated is more accurate and latest.
  • The Estimate sales report includes recent orders regardless of whether they have been shipped. Estimated sales report provides important information like amazon order id, the selling price, Amazon service charges, title of the item, ASIN of the item, status of the item (i.e shipped, unshipped, cancelled or pending), the date and time of the item sold and the sellerSku of the item. SellerSku provides information on which customer has scanned the item for selling the item to the amazon.
