Cartwell documentation

Getting started in 5 minutes →

1. Installing the app

Install Cartwell from the Shopify App Store, or enter your store domain on the Cartwell home page. After approving the requested permissions you'll land in the app inside your Shopify admin and be asked to choose a plan to start your free trial.

2. Enabling the cart drawer

Cartwell renders on your storefront through a theme app embed. To switch it on:

• Go to Online Store → Themes → Customize.
• Open App embeds in the left panel.
• Toggle on Cartwell Cart Drawer and click Save.

Open your storefront, add a product to the cart and click the cart icon — the Cartwell drawer slides in. No theme code changes are required.

3. Free shipping & rewards

Shipping bar

In Shipping, set the cart total that unlocks free shipping and the message shoppers see. The drawer displays a progress bar that fills as items are added and confirms when the goal is reached.

Geo-targeting (Premium)

On Premium you can define different thresholds per country, so shoppers see the right free-shipping goal for their region automatically.

Gift rewards

Under Shipping → rewards, set a cart goal and choose a gift product with the product picker. When a cart qualifies, the gift is added automatically and made free using an automatic discount in your store. The discount is created, updated and removed for you as you change the reward.

4. Upsells

In Upsells, create an offer and select one or more products to recommend. For each offer you can set a trigger that controls when it appears — for example, only when a specific product or collection is already in the cart. The recommendation is shown inside the drawer with an add-to-cart button.

• Starter: upsells are not included.
• Growth: up to 10 upsell offers.
• Premium: unlimited upsell offers.

5. Customizing the look

In Customize you can:

• Start from one of five theme presets.
• Choose from 20 Google Fonts and set your brand colors.
• Set the drawer position and width.
• Edit storefront text and translations.
• Add custom CSS (Premium) for full control.

Click Save and reload your storefront to see changes live.

6. Plans & billing

Manage your subscription on the Billing page. You can upgrade or downgrade at any time; features adjust to your plan immediately. Charges are processed securely through Shopify Billing, and any usage-based charges above your plan's included volume are shown to you before they apply.

7. Analytics

The Analytics page shows a conversion funnel (cart opens, add-to-cart, checkout starts), an event breakdown, device split, average cart value, top-performing upsells and discount insights. Premium includes a longer history and CSV export. Storefront interactions appear after a short processing delay.

8. Uninstalling

Remove Cartwell from Settings → Apps in your Shopify admin. After uninstall, Shopify notifies us and we delete your store data in line with our Privacy Policy.
