Bulk CSV profit margin auditor
Upload your inventory CSV — we flag loss-makers and compute the minimum price for your target margin on every SKU. Local-only, no upload.
Frequently asked questions
Which CSV columns do I need?
At minimum: name, price, cost — plus optional shipping. Headers are auto-detected (sku/title/product, sale price, cogs/unit cost, shipping) and re-mappable in the UI.
Is my data uploaded anywhere?
No — all parsing and calculation run locally in your browser on the same engine as the single-item calculators. Nothing leaves your device.
What does the suggested price column do?
It runs the reverse gross-up solver for a target profit margin (default 30%) and returns the minimum list price that hits it on each row.
Can I audit a whole marketplace store?
Yes — select a platform (including eBay/Amazon/TikTok category variants), drop in your exported order/inventory CSV, and every row gets fees, profit, margin and a suggested reprice.
