I ve been looking into how businesses handle supplier price list updates, especially when they receive a new CSV or XLSX and need to understand what actually changed.
A few things seem surprisingly manual:
finding which SKUs increased or decreased in cost
identifying new and removed products
checking how cost changes affect current margins
calculating a new selling price when you want to preserve the previous margin
I built CostRift around this workflow, but I m especially interested in how people handle it today.
Compare old and new supplier price lists in CSV or XLSX, detect price changes, added and removed items, and see how each change affects your margin. CostRift also calculates the target selling price needed to preserve your previous margin. Your supplier files stay in your browser and are never uploaded.
