How it sells itself

Pick products from your catalog and add competitor URLs — eMAG, Altex, other structured-price pages. We re-read their public list price on your plan's schedule — weekly, daily or hourly, up to 500 products per pass. Home scores the products it compared and ranks them reprice-first by gap over the cheapest in-stock rival.

Compare your price with tracked competitor prices in Shopify. Review suggested matches or add known product URLs, then follow daily changes and configure alerts. You keep control of pricing: SKU Surf does not reprice your products. Price-difference comparisons require a single-variant Shopify product and a healthy tracked price in the same currency, checked within 26 hours.

Key points
  • Watchlist from your Shopify catalog + any public competitor URL (eMAG, Altex)
  • Catalog-wide pricing-health score + an overpriced-first reprice list
  • Per-product rank and exact % gap vs every competitor you track
  • 30-day price history + fresh-undercut detection when a rival crosses below
  • Track up to 300 products across competitor channels
  • Review AI-suggested competitor URLs before tracking
  • See daily changes and MAP-style flags inside Shopify
