StoreSentry watches the Shopify stores you compete with and tells you when something actually changes: price drops and hikes, new product launches, items selling out or coming back in stock. No dashboards to babysit and no pixel-diff false alarms — we read structured catalog data, so every alert is real. You get one clean digest by email or Telegram: daily, weekly, or instant. Built for small stores watching 1–15 competitors, not enterprise pricing teams. Set up in two minutes.

• Price change alerts with old vs new price and percentage
• New product launch detection across the whole catalog
• Sold-out and back-in-stock signals per variant
• Daily, weekly or instant digests — email and Telegram
• Two-minute setup — paste a competitor store URL and you are done

Shopify keeps one cost per item, with no history and no supplier link. When a supplier raises prices, the field goes stale and profit reports drift. CostSentry tracks supplier price lists in your admin. Upload a CSV or XLSX file: rows match your catalog by SKU or brand and part number, get compared with the previous list, and every change shows its margin impact at current retail. SKUs below your margin floor are flagged with a suggested price, and you can update cost in Shopify in one click.

• Import supplier price lists from CSV or XLSX with saved column mapping
• See every cost change with margin impact at your current retail prices
• Flag SKUs below your margin floor with a suggested new retail price
• Update cost per item in Shopify in one click, per SKU or in bulk
• Email digests on cost changes plus cost history for every supplier
