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.
StoreSentry tracks the Shopify and WooCommerce stores you compete with: price drops and hikes, new product launches, sold-outs and restocks. No pixel-diff false alarms — it reads structured catalog data, so every alert is real. One clean digest by email or Telegram: daily, weekly, or instant. Paste a store URL, the platform is detected automatically. Free for 1 competitor forever; paid plans from 19 USD/mo with a 14-day trial. Built solo for small stores, not enterprise pricing teams.
