07 / FAQ

Questions we hear about Cartlift.

Answers drawn from how the app works today.

Install the app Book a demo

Where can Cartlift show offers?

On the product page, in the cart, at checkout, right after payment, and on the thank-you and order status pages. There are 21 campaign types grouped by page, plus a Smart Cart drawer that replaces the default cart.

How are discounts applied?

Automatically through Shopify, free shipping included, using Shopify Functions. You set the combine rules, so bundle discounts and codes stack only where you want them to.

Will the widgets match my theme?

Yes. Every widget is built in a drag-and-drop editor where you set colours, type, spacing and layout to match your storefront.

Does it work with multiple currencies and languages?

Yes. Offers and the Smart Cart follow the shopper's currency and language, so international stores run one set of campaigns.

Do I need Shopify Plus?

No. Only checkout offers need Plus, because they run inside native checkout. Everything else works on any Shopify plan.

What do the analytics show?

Views, clicks, conversions and revenue for each campaign, so you can keep the offers that earn their place and switch off the ones that do not.

Can I run more than one Smart Cart?

You can build several layouts and switch between them, but only one Smart Cart is live at a time.
