BOB is KartSmith's all-in-one Shopify conversion app. It brings five merchandising tools under one roof so you can launch bundles, tiered discounts, cart upsells, styled variants, and navigation — all from a single dashboard, without editing theme code.
This guide is for merchants. You don't need to know how to code to follow along.
The five building blocks
BOB ships with five features. Each one stands on its own, and each one is also a building block for bigger campaigns.
- Variant Styling — swap Shopify's default variant pills for images, swatches, or color chips. Link separate products together so they appear as options on a single listing.
- Volume Discounts — reward larger carts with Buy X Get Y offers, combo bundles, and quantity break pricing.
- Product Bundles — drop-in bundle templates that render right on the product page.
- Cart Drawer — a branded cart slide-out with upsells, progressive discount meters, and free-gift thresholds.
- Menu — homepage and product-page navigation templates tuned for mobile and desktop.
The real story: composition
Running any one feature will lift conversion. Running several together is where BOB earns its keep.
A holiday campaign might pair a Product Bundle on a landing page with a Cart Drawer upsell and a Volume Discount at checkout. A new-product launch might combine Variant Styling and Product Linking with a fresh Menu template. We call these combinations campaigns, and the ordered paths they create are funnels.
See the Playbooks section for ready-made recipes once you're set up.
