FAQ

Frequently asked questions

Everything you need to know about installing, configuring and billing for Cartwell.

Getting started

What does Cartwell do?

Cartwell replaces your store's default cart with a fast slide-out drawer. Inside it you can run a free-shipping progress bar, product upsells and automatic gift rewards — all designed to grow average order value without sending shoppers to a separate cart page.

Do I need to edit any code?

No. Cartwell installs as a Shopify theme app embed. You enable it once in the theme editor and the drawer starts working. Everything else — offers, styling, text — is configured inside the app, no code needed.

Does it work with my theme?

Cartwell works with any Online Store 2.0 theme. It opens on top of your storefront, so it does not depend on your theme's own cart, and you can style it to match your brand.

Will it slow down my store?

The storefront script is lightweight and loads asynchronously, so it does not block your page. The drawer only fetches data when a shopper opens the cart.

Features

How do free-shipping bars work?

Set a cart total that unlocks free shipping. The drawer shows shoppers a progress bar and how much more they need to add. On Premium you can set different thresholds for different countries.

How do upsells work?

Create offers and pick the products to recommend. You choose when each offer appears — for example only when a specific product or collection is already in the cart — and the suggestion shows inside the drawer.

How do free gifts work?

Choose a cart goal and a gift product. When a cart qualifies, Cartwell adds the gift automatically and makes it free using an automatic discount in your store. Remove the qualifying items and the gift is removed again.

Can I customize how it looks?

Yes. Start from one of five theme presets, then adjust colors, fonts (20 Google Fonts), drawer position and width. Premium plans can add fully custom CSS.

Does Cartwell support multiple languages?

Yes. The storefront text can be translated, and the drawer can follow the shopper's locale.

Does it work on mobile?

Yes. The drawer is fully responsive and is designed mobile-first, since most storefront traffic is on phones.

Plans & billing

Which plan do I need?

Starter is great for a single shipping bar and gift. Growth adds up to 10 upsells, more tiers and store extras. Premium unlocks unlimited offers, geo-targeting, custom CSS and the longest analytics history.

Can I change plans later?

Anytime. Upgrade or downgrade from the Billing page in the app. Your features adjust to the new plan immediately, and billing is handled securely through Shopify.

How is usage-based billing calculated?

On high-volume stores, charges above the included monthly order volume are billed per use up to a capped amount, which is shown to you before you approve it. Most stores stay within the plan price.

Is there a free trial?

Yes — every plan starts with a free trial so you can set everything up and see the drawer live before you are charged.

Privacy & support

What data does Cartwell collect?

We process your store settings, an encrypted access token, limited order data for billing and analytics, and anonymized cart interaction events. We never collect shopper names, emails or payment details. See the Privacy Policy for full detail.
