Field notes
The workflow compares old and new supplier price lists in CSV or XLSX format, matches SKUs, and calculates both cost movement and resulting gross-margin impact. It flags products below a user-selected target and accounts for new or discontinued SKUs. The sample table reports 17 products below a 30% margin target, 41 cost increases, and a largest single increase of 30.4%. The homepage says processing occurs in the browser without uploading data to a database.
