About CartBoost Slide Cart & Upsell

Modern slide-out cart drawer with shipping progress goals and 1-click upsells.

Modernize your store's shopping cart with an ultra-fast, slide-out cart drawer designed to elevate buyer experience and boost average order value. CartBoost replaces outdated standard cart pages with a seamless, responsive slide-out cart drawer that opens instantly upon adding items. By keeping customers on the product page and guiding them toward free shipping, CartBoost helps shoppers complete purchases with confidence. Dynamic Free Shipping Progress Goals: Encourage larger basket sizes with a real-time shipping goal bar. Customers see live calculations showing exactly how much more they need to spend to unlock free delivery. Once reached, a celebratory completion banner reinforces their purchasing decision before heading to checkout. In-Cart 1-Click Accessory Upsells: Showcase complementary add-ons and accessories right inside the cart drawer. Shoppers can add relevant items with a single tap, updating their cart total and free shipping progress without disrupting their browsing flow. 100% Theme App Extension: CartBoost is built natively using Shopify 2.0 Theme App Extensions (App Embeds). It works out of the box with modern OS 2.0 themes. Installation takes one click in your theme editor, and uninstallation leaves zero residual code or script tags in your theme. Tailored Brand Presets & Mobile First: Choose from 3 carefully tuned visual presets (Minimal, Boutique, and Bold) or customize accent colors, corner radiuses, and button styles. Fully responsive, adapting effortlessly into an elegant bottom-sheet modal on mobile devices.
