CostSentry
Catch supplier cost hikes before they eat your margins
Shopify keeps one cost per item, with no history and no supplier. CostSentry reads supplier price lists (CSV or XLSX), shows each increase with its margin impact, flags SKUs below your margin floor with a suggested retail, and writes cost back in one click.
Hi Product Hunt. I spent about twenty years building ERP and repricing systems for auto parts sellers, and one problem never went away: the selling platform has no idea what happens on the supply side. Shopify keeps a single cost per item. No history, no supplier behind it. A distributor sends a new price list, the field goes stale, and every profit report after that is quietly wrong.
CostSentry is the tool I wanted all those years. You upload the supplier's price file the way it arrived, CSV or XLSX. It matches rows to your catalog by SKU or by brand and part number, then shows every increase with its margin impact at your current retail. Anything that falls below your margin floor gets flagged, together with the retail price that would hold it. Cost is written back to Shopify only when you say so.
There is a free plan. If you run a store on supplier price lists, I would like to hear how you track cost changes today. Most answers I get are some version of "the bookkeeper notices at quarter end" or "we don't".
