Turn your thank-you page into a growth channel

PostCart adds customizable widgets to your Shopify order confirmation page — surveys, product upsells, next-order discounts, social follows, and branded messages — plus a built-in analytics dashboard to measure what actually converts.

• Five ready-to-use widgets. Message, Survey, Product Upsell, Next-Order Discount, and Social Follow — all configured in Shopify’s native checkout editor, no code required.
• Engagement analytics. Track impressions, clicks, copies, and survey responses per widget so you can see which blocks drive repeat purchases.
• Built on checkout UI extensions. Modern, future-proof architecture fully compatible with Shopify’s 2026 checkout extensibility requirements.
