About CostRift

CostRift helps businesses compare old and new supplier price lists in CSV or XLSX and quickly understand what changed. Detect price increases and decreases, new and removed SKUs, items that need review, and how supplier cost changes affect margins. When selling prices are included, CostRift calculates the target selling price needed to preserve the previous margin. Supplier files are processed locally in your browser and are not uploaded to CostRift servers.

I built CostRift to make recurring supplier price-list updates easier to review. I’m especially interested in how merchants currently compare supplier cost changes and protect their margins.
