BoostFlow adds optional product add-ons in the cart and Shopify checkout, and can show a product offer after payment. Add-ons stay unchecked until the buyer chooses them. Offers use catalog products, so the name, image, and price match the store. Merchants enable offers in the admin, then add the cart embed and checkout block. Accepted offers can be tagged on the order. The admin shows impressions, conversions, and offer revenue. Charges use the Shopify Billing API.

• Optional cart and checkout add-ons that stay off until the buyer selects them.
• Post-purchase offers with Pay now and Decline, without re-entering card details.
• Order tags plus analytics for impressions, conversions, and offer revenue.
