Finally, Shopify-level upsells come to Squarespace

Cartify is the first AI-driven, fully customizable cart upsell engine built natively for Squarespace. Boost AOV with in-cart recommendations, cross-sells, and 1-tick shipping protection — no redirects, no code required.

Squarespace Cart Upsell

Turn every cart into a revenue engine

For years, Squarespace merchants were left behind

Shopify stores have run advanced cart-upsell apps for years, quietly compounding their AOV. Squarespace never had a true native equivalent — until now.

Cartify is the first AI-driven, highly customizable cart-drawer upsell engine built natively for the Squarespace ecosystem, so you can keep shoppers in the funnel and maximize every order without writing a single line of code.

Have had this for years

  • Mature app ecosystem for cart upsells & AOV tools
  • In-cart cross-sells as a standard growth lever
  • Shipping protection built into checkout flows
Squarespace, before Cartify

Left without the tooling

  • No Cart upsells at all
  • No native AI recommendations inside the cart drawer
  • Revenue left on the table, order after order
Squarespace + Cartify Square

Caught up — and built to last

  • AI recommendations & cross-sells, right in the cart
  • 1-tick shipping protection with zero page reloads
  • Built natively for Squarespace — zero code, zero redirects

The first AI-powered engine for Squarespace

Cartify learns from your customers and drives extra revenue by suggesting products shoppers actually want, right before checkout — without redirecting them anywhere.

AI-Autopilot

Put upsells on autopilot. Our engine reads the cart’s contents and automatically suggests the products most often bought alongside it.

Smart recommendation modes

Choose Manual to push your high-margin inventory, AI Autopilot for intelligent cross-sells, or Hybrid to blend both.

Smart fallbacks & auto-exclusion

Never miss an opportunity: set default backups to show on empty carts, while smart logic keeps out anything the shopper has already added.

Every detail of the timer, under your control

The Countdown Timer is actually three distinct tools in one, built specifically for how Squarespace stores run promotions.

Full control over how upsells look and feel

Squarespace upsells

Multiple layout styles

Show cross-sells however suits your store: a clean vertical list, an organized grid, or a space-saving, interactive slider.

Smart accordion, clutter-free

Keep the checkout button above the fold — upsells wrap in a sleek accordion that auto-collapses once a shopper adds more than two items.

Grid & placement control

Fine-tune your strategy: choose how many products to show, up to eight, adjust products per row, and place the widget above or below cart items.

Responsive device control

Perfect your strategy across every screen with independent visibility toggles for desktop, tablet, and mobile.

Cart Upsell

Matches your storefront, down to the pixel

Granular element toggles

Choose exactly what shows on each product card — images, prices, descriptions, quick-view triggers, and add-to-cart buttons, one click at a time.

Image & layout styling

Polish the aesthetic with a choice of seven image aspect ratios and precise control over image border radius.

Complete theme & type control

Match your brand fully: background, text, and hover colors, plus a full typography engine for font family, size, weight, and line height on every element.

Pure-profit revenue, without a separate insurance app

Squarespace shipping protection

Dynamic cart-value tiers

Set pricing rules that automatically adjust — e.g., $1.99 for orders under $50, $2.99 for orders over $50 — so pricing always feels proportional to the cart.

Auto-swapping magic

If a customer changes their cart total, Cartify instantly and silently swaps the protection tier in the background. No page reloads. No friction.

Fixed pricing mode

Prefer simplicity? Offer a single flat-rate protection add-on regardless of cart size.

Free shipping bar safe

The cost of the protection plan is smartly excluded from your free-shipping progress bar, so it never artificially triggers free shipping.

Add Cartify to your Squarespace store in minutes — no code, no redirects, just a smarter checkout.
