How it sells itself

Carty puts an Add to cart button under every product on your collection, home and search pages, so shoppers buy in one tap instead of five clicks. They pick variants and quantity right on the card, and after every add Carty keeps selling: a free shipping progress bar, product recommendations and a sticky buy bar on product pages.

Maximize cart conversions on your Shopify store with STKY Sticky Add To Cart. Ensure Add to Cart is always visible, reducing cart abandonment. Countdown Timer urgency feature converts even more! Quick Buy Button enables swift orders directly on product pages. The Sticky Checkout Bar gives a cart overview, helping checkout. With our Ajax Slider Cart Drawer, even upsell & cross-sell additional products & increase AOV.

Key points
  • Add Quick Add to Cart button on Collection, Home, Product, and Search pages.
  • Add a quantity selector to make it possible to add more than one product.
  • Fully customize 'Add to Cart' buttons to match your store.
  • Instant checkout: Skip the cart page and send customers straight to checkout.
  • Sticky Add To Cart Bar & Sticky Cart features - faster, easier checkout
  • StickyCart Icons & Add To Cart Bar - always in view for quick checkout
