Why you need this
Upsell Popups First ever on squarespace
Lift your order value with a upsell popup that knows exactly what to suggest.
Native “Related Products” widgets sit below the fold, where almost no one scrolls. For the first time on Squarespace, you can trigger relevant, AI-powered upsell and cross-sell popups at the exact moment buying intent peaks — right as they click Add to Cart.

Three things native Squarespace can’t do
Native cross-sells sit below the fold
Default related-product blocks live at the very bottom of the page. On mobile, that’s a four-finger scroll past the reviews and the footer. Nobody sees them.
One-item carts that should’ve been three
The customer wanted the shirt. You also sell the matching trousers and the tote. None of it surfaced at the right second, so the order shipped smaller than it could have.
Wasted intent at the easiest moment to sell
By the time a shopper hits “Add to Cart,” their wallet is already out. Native Squarespace has no way to trigger an offer at that exact moment — ours does.
Lift AOV without annoying your shoppers
Increase your average order value without slowing down your page or wearing out your customers' patience.
AI-Autopilot
Put popup 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.
The right offer, at the exact right second.
Trigger popups based on real shopper behavior, so offers feel timely instead of intrusive.
Instant action
Add to Cart
Strike while the iron is hot. Fire the popup the exact millisecond a customer adds an item to their cart.
Save the sale
Exit-Intent Technology
Detect when a visitor’s cursor moves to leave the window and present a last-second offer before you lose them for good.
Timed
Engagement-Based Delay
Trigger the popup only after a visitor has spent a set number of seconds browsing, so you’re not interrupting the first glance.
Depth-based
Scroll Depth
Show your offer exclusively to engaged shoppers who’ve scrolled past a specific percentage of the product page.
Relevance over revenue-chasing.
Selling to an existing buyer costs roughly 5× less than acquiring a new one — so it’s worth showing them something they actually want.
Manual rules
Exact Product Mapping
Build “if this, then that” funnels by hand. If they add the Linen Shirt, guarantee the popup shows the matching Linen Trousers — every time.
AI-powered
AI-Powered Recommendations
Don’t want to build rules manually? Let the AI engine read the current product context and automatically surface the items most likely to convert.
Fallback
Hybrid & Fallback Modes
Set a default list of global best-sellers to show when no specific rule matches, so an offer is always presented.
Granular control
Per-Page Targeting
Per-product and per-category include/exclude rules give you absolute control over exactly where offers are allowed to appear.
Match your brand in minutes.
A seamless experience that feels like a native part of your Squarespace store — not a clunky third-party app bolted on top.
Zero code
Visual Panel Editor
Launch beautifully branded popups in minutes with a visual panel editor. No developer required.
Layouts
Grids, Lists & Carousels

Typography
Inherits Your Fonts
Your popup automatically inherits your site’s native Squarespace fonts, or you can define your own typography from scratch.
Aesthetics
Corners, Ratios & Blur
Adjust corner radiuses, image aspect ratios, and toggle modern blurred backdrop effects for a high-end feel.

Common questions.
What is a Squarespace upsell popup?
It’s an on-site modal that surfaces relevant product recommendations at key moments in the shopping journey — like adding to cart or attempting to leave the page — to increase average order value without relying on native related-product widgets buried at the bottom of the page.
Can I trigger a popup when someone clicks Add to Cart on Squarespace?
Yes. The Upsell Popup fires the instant a shopper adds an item to their cart, showing complementary products while buying intent is highest — something native Squarespace can’t do on its own.
Can I control exactly which products trigger which popup?
Yes. Build manual “if this, then that” product mapping rules, or let the AI recommendation engine choose automatically — with a fallback list of best sellers whenever no rule matches.
Can I choose the popup upsell products manually instead of using AI?
Yes. Manual mode lets you hand-pick which products always appear as an popup upsell. Hybrid mode prioritizes your picks first and lets AI-Autopilot fill any remaining slots — useful if you want to guarantee one product but leave the rest to the algorithm.
Will the popup match my Squarespace site's branding?
Yes. Popups inherit your site’s native Squarespace fonts by default, and every color, corner radius, layout, and element can be customized from a visual panel editor — no code needed.
Is this different from Squarespace's built-in Related Products feature?
Yes. Squarespace’s native Related Products section sits at the bottom of the product page and only pulls from the same category. Our popup fires at the moment of highest intent — right when they click Add to Cart — and lets you control exactly which products pair with which, manually or with AI.
Do I need to know how to code?
No. Everything is configured through a visual panel editor — triggers, design, and product mapping.
How does the AI decide what to recommend?
It analyzes the current product’s context (category, price point, past pairing performance) to suggest items likely to convert, and falls back to your best-sellers list if nothing matches.
