OptInCart Shopify app

Variant certainty at the moment of add-to-cart.

OptInCart adds a high-confidence swatch preview directly inside the add-to-cart button. Shoppers see the exact color, size, or style they selected before they checkout, dramatically reducing mis-orders and support tickets.

How OptInCart runs

Purpose-built for Shopify storefront and checkout

Install from the Shopify App Store and approve app embed + cart script blocks.

2. Map variants

OptInCart detects variant media automatically. Override or prioritize specific shots per option.

4. Track & iterate

Review conversion uplift and cart error drops in the built-in analytics dashboard.

Where OptInCart shines
