CostRift
Compare supplier price changes and protect your margins
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.
Hey Product Hunt! 👋
I built CostRift to solve a very practical problem: suppliers send updated price lists, but figuring out what changed and what those changes actually do to your margins is often a manual spreadsheet job.
CostRift lets you compare a previous and current supplier price list in CSV or XLSX and quickly see:
• price increases and decreases
• added and removed SKUs
• margin impact when selling prices are provided
• the target selling price needed to preserve the previous margin
• unresolved or ambiguous SKU matches that need review
Privacy was important to me, so supplier files are processed locally in the browser and are not uploaded to CostRift servers.
You can also try the core comparison without creating an account.
I’d especially love feedback from e-commerce operators, purchasing teams, distributors, and anyone who regularly works with supplier price lists. What would make this more useful in your workflow?
