The Problem

The cart is where conversion gets won or lost

Customers may add products but hesitate before checkout. Merchants need product recommendations, cart incentives, discount handling and recovery tools without stitching together a slow, fragile stack of apps.

The cart leaks revenue

A default cart often misses chances to show related products, free shipping progress, urgency, notes and discount controls before checkout.

Too many separate tools

Merchants may need multiple apps or custom development to build a better cart, which can make the store slower and harder to manage.

Abandoned carts pile up

Customers add products, hesitate, and leave. Merchants need a cleaner way to reduce friction and bring shoppers back.

The Solution

A conversion-focused cart drawer

Speed Cart gives merchants a customizable slide-cart drawer with upsells, cross-sells, sticky cart access, free shipping progress, discount fields, order notes, countdowns and recovery features. The goal is a cart that feels faster for shoppers and more profitable for merchants.

Key Features

Cart tools packed into one clean drawer

Slide Cart Drawer

A fast drawer lets customers review items, update quantities and keep shopping without leaving the current page.

Upsells & Cross-Sells

Merchants can show relevant product recommendations inside the cart to increase cart value before checkout.

Sticky Cart Button

A persistent cart entry point makes it easier for shoppers to open the cart from anywhere in the store.

Free Shipping Progress

Progress logic encourages customers to add more items by showing how close they are to free shipping or cart rewards.

%
Discounts & Order Notes

Customers can add discount codes and order notes directly inside the drawer for a smoother purchase flow.

Abandoned Cart Recovery

Recovery features help merchants bring customers back after they leave the cart without finishing checkout.

My Role

Product and technical development

I worked across planning, Shopify app features, storefront widget improvements, merchant configuration and API integration to support real cart optimization needs.

Technical Approach

Merchant settings separate from storefront rendering

The architecture keeps merchant configuration in the app backend while the storefront widget renders a fast, responsive drawer. That separation makes the app easier to customize, scale and maintain across Shopify themes.

Product Challenges

Powerful cart optimization without storefront drag

Feature-rich without feeling crowded

Challenge

Cart drawers can quickly become overloaded with offers, notes, countdowns, progress bars and discount fields.

Approach

Keep the drawer structure modular so merchants can enable conversion tools without turning the cart into visual noise.

Fast across Shopify themes

Challenge

The cart widget runs directly on the storefront, where performance and theme compatibility matter immediately.

Approach

Separate merchant configuration from storefront rendering, keep the widget lightweight, and test across different theme layouts.
