Custom Cart Drawer

Turn your cart into a true revenue engine

We turn your cart into a high-converting layer with upsells, add-ons, and real-time interactions that increase average order value.

Theme-native Mobile-first Built for conversion
The problem

The problem with standard Shopify carts

Default cart drawers leave conversion on the table. Generic apps make the storefront feel cluttered. There's a better way.

Generic default cart

Stock Shopify drawers feel functional but flat. No upsells, no progress bars, no premium polish.

Low average order value

Without contextual upsells and add-ons, customers check out before discovering complementary products.

Clunky cart apps

Off-the-shelf cart apps slow your store, break your theme styling, and rarely match your brand.

No bundle awareness

Bundles, mix & match flows, and cross-sells need a cart that understands them. Most don't.

Cart comparison

Why settle for the default cart?

Same customer, same products. Two completely different conversion experiences.

Our process

How we build your cart drawer

A conversion-focused process designed to turn your cart into a high-performing revenue layer.

01

Strategy & cart audit

We analyze your current cart, checkout flow, and AOV opportunities identifying where friction points exist so we can design a cart that actually drives more revenue.

02

UX & wireframing

We map how your cart should behave from upsell placement and add-on flows to thresholds, bundles, and interactions.

03

Custom cart drawer build

We build your cart drawer directly in your theme using clean, scalable code integrating upsells, add-ons, bundles, and real-time updates without relying on external apps.

04

QA, launch & optimisation

We test every interaction across devices, launch the cart, and refine performance to ensure everything runs smoothly and continues to convert post-launch.

FAQs

Common questions

Yes. Most clients move off Slide Cart, UpCart, or similar paid apps once the custom drawer is live. The drawer ships as part of your theme, so there's no monthly fee, no script bloat, and full control over the experience.
In most cases, yes. We adapt to popular themes (Dawn, Impact, Prestige, Symmetry, etc.) and match your brand styling. We'll review your theme during the discovery call and confirm fit.
Yes. Free shipping thresholds, upsell products, accent colors, banner copy, addon products, and gift wrap settings all live in the theme customiser. You won't need a developer for everyday updates.
Mobile-first by design. The drawer, toggles, quantity controls, and progress bar are all sized for thumbs and tested across iOS and Android.
Yes. The drawer reads native Shopify variants, line item properties, and metafields. Bundle items group correctly, subscription line items are tagged, and custom properties (gift messages, addon flags) flow through to the order.
Starter scope typically ships in 1–2 weeks. Advanced scope with logic, variants, and integrations takes 2–4 weeks. Custom scope is timeline-dependent on scope.
