Frequently asked questions.

Cartylabs Checkout adds native UI extensions to your Shopify checkout — smart upsells at the order summary, a shipping & rewards progress bar, shipping protection, gift wrap, payment & trust icons, Trustpilot social proof, promotional banners, custom order notes, conditional T&C checkboxes, and full branding control on Plus. It is built entirely on Shopify's Checkout UI Extensibility platform — no scripts, no theme edits.

Extensions on the Checkout page, Thank You page, Order Status page, and Post-Purchase work on any Shopify plan (Basic, Shopify, Advanced, or Plus) that has Checkout Extensibility enabled. Checkout Branding (custom CSS, unlimited branding profiles, advanced scripts) requires Shopify Plus.

No. Extensions are built on Shopify's native Checkout UI Extensibility platform and run in a sandboxed environment optimized for performance. They add 0 ms of measurable checkout latency, no external scripts, and no impact on Lighthouse.

Yes — checkout runs as native Shopify UI extensions, meaning it lives inside Shopify's checkout, not your storefront theme. There are no theme files to edit and no compatibility concerns regardless of which theme you use.

Yes. Each buyer-journey stage has its own independent configuration. You can show completely different banners, recommendations, and rewards on each page.

Product Recommendations: 25 rules. Rewards Progress Bar: 10 rules. Banners: 10 rules. Terms & Conditions: 10 rules. Post-Purchase Upsell: 10 rules. Rules are evaluated in priority order and the first match fires.

Yes. Conditions support cart total, products in the order, customer country, customer language, and customer tags. Layer multiple conditions per rule for precise targeting.

No. When you save a rewards rule with discount milestones, the app automatically creates a Shopify discount function that applies at checkout when the customer hits the milestone. No manual codes needed.

Yes. Every block is configured in the Shopify Checkout Editor with a live preview of exactly how the extension will look before you push to production. Test configurations safely before going live.

Yes. Because Cartylabs uses Shopify's native checkout UI extensions, it co-exists with any other app on the same platform. You manage which blocks appear, and in which order, directly from the Shopify Checkout Editor.

Pro includes all checkout and post-purchase extensions for any Shopify plan with Checkout Extensibility (Basic and above). Plus Pro adds Plus-only features: full checkout branding/custom CSS, unlimited branding profiles, advanced scripts, dedicated CSM and SLA-backed support.

After a customer completes payment, Cartylabs shows a one-click upsell on the Thank You page. The customer accepts with a single tap — their payment method is already on file, so there's no card re-entry. Accepted items are added as a new order on the same payment.

No. The offer appears after payment is complete, so it cannot hurt your primary checkout funnel. Every accepted offer is pure incremental revenue with zero downside risk.

Two placements: the Thank You page (the moment after payment — highest intent, lowest friction) and the Order Status page (every time the shopper returns to track their order, you can surface a contextual follow-up offer).

Any Shopify plan (Basic, Shopify, Advanced, or Plus) with Checkout Extensibility enabled. No Plus required.

Rule-based targeting lets you fire offers by what they bought, cart total, customer country, language, customer tag, or first-time vs repeat. Up to 10 rules per page, evaluated in priority order.

Drag-and-drop blocks for: smart product recommendations, countdown offers, rewards/loyalty progress, customer reviews, payment & trust icons, social follow buttons, and promotional banners. Reorder anytime, no code.

Cartylabs merchants average a +22% AOV lift and ~11% attach rate on post-purchase offers. Most stores see results within the first week of going live.

The dashboard shows attach rate, AOV lift, and total revenue attributed to each post-purchase rule, with date-range and rule-type filters so you can identify exactly which offers are driving incremental revenue.

Cartylabs is built on Shopify's native Checkout Extensibility (zero added latency, no scripts), bundles post-purchase + checkout + cart drawer in one app, and includes a permanent free plan. Most merchants save $150-200/mo by consolidating their stack.

From the dashboard, open Cart Drawer → Style to control colors, fonts, spacing, layout of upsells, and the rewards bar. Custom HTML/CSS is supported on the Growth plan and above.

Three configurable behaviors: open the slide-out cart drawer, redirect to the cart page, or send straight to checkout. Configure per feature under Button/Basic Settings.

Yes. Shoppers enter codes inside the drawer with instant validation (no page reload), and Cartylabs surfaces auto-applied discounts as line items so the value is always visible.

The shipping bar shows real-time progress toward thresholds you define. Combine it with rewards milestones to unlock gifts and stacked discounts as the cart grows ($50, $75, $100+).

Fully. The drawer adapts to mobile width, supports swipe-to-close, is thumb-friendly, and is performance-tuned to keep your Lighthouse mobile score intact.

Yes. Express payment buttons surface directly inside the drawer for one-tap checkout on returning shoppers.

Cartylabs analyzes cart contents, the shopper's browse history, and store-wide co-purchase patterns to surface the offer most likely to be added. You can also manually curate offers by collection, product, or rule.

Cartylabs AI upsells convert at 8-12% on average, vs 2-3% for generic widgets. The AI is tuned to surface products customers are likely to want based on actual behavior, not blast every offer.

FBT bundles use co-purchase data to surface products most often bought alongside what's in the cart, with a one-click add-all button.

Yes. Trigger discount or gift offers based on cart value, item count, customer segment, country, language, or referrer.

Three locations: cart drawer (pre-checkout), order summary (in-checkout, on Plus or via extensibility), and Thank You / Order Status (post-purchase, one-click on saved card).

The Analytics dashboard shows views, clicks, conversion rate, and revenue per upsell offer. Filter by date range, segment, placement, or product.

For both desktop and mobile: Sticky Bar → Button Settings → Actions → Go to Checkout. The sticky button and quick-buy buttons each have the same option.

The sticky bar spans the full width with product info and a CTA. The sticky button is a compact floating button that appears when shoppers scroll past the original add-to-cart.

A small badge on the cart icon showing the number of items added. It nudges shoppers back to the cart and lifts conversion for return visitors.

It works in Chrome, Edge, Firefox, and Opera (~81% of global traffic). Safari and IE don't allow favicon updates after page load.

Make sure the feature is enabled for both desktop and mobile, then wait 1-2 minutes after saving. If it still doesn't appear, email support@cartylabs.com with the product URL — we'll integrate with your theme for free.

Under 10 minutes for the full stack. Install from the Shopify App Store, open the dashboard, toggle the features you want, and you're live. No theme code edits, no developer required.

Yes. The cart drawer and sticky bar are tested against 150+ Shopify themes including Dawn, Impulse, Prestige, Symmetry, Stiletto, and all popular Shopify Plus themes. Checkout extensions run inside Shopify's native checkout, so theme compatibility doesn't apply there. If you hit an issue, we integrate with your theme for free.

Yes — every feature is mobile-first. Cart drawer, sticky bar, rewards, quick-buy buttons, checkout extensions, and post-purchase pages are all designed for touch and tested on iOS Safari, Android Chrome, and every modern desktop browser.

Yes. Cart and storefront changes have a side-by-side WYSIWYG preview. Checkout extensions have a live preview in the Shopify Checkout Editor. Post-purchase pages have a live drag-and-drop builder.

Cartylabs integrates via Shopify App Embed and native Checkout Extensibility, which work with any storefront that uses Shopify's checkout and cart API. For fully custom JavaScript storefronts (Hydrogen, etc.), we offer a REST API for deeper integration. Email support@cartylabs.com with your stack and we'll review.

No. Cart drawer, sticky bar, AI upsells, post-purchase upsells, and most checkout extensions work on every Shopify plan with Checkout Extensibility (Basic and above). Plus unlocks checkout branding (custom CSS, unlimited branding profiles, advanced scripts).

Yes. Install Cartylabs on your dev store, toggle on the features you want, and use Shopify's native preview tooling. We recommend a final check on your live store once configured.

No. Storefront features load asynchronously via Shopify's App Embed and are performance-budgeted. Checkout and post-purchase extensions add 0 ms latency because they run on Shopify's native UI extensibility platform with no external scripts.

Yes. Data is encrypted in transit and at rest, hosted on SOC2-certified infrastructure, and never shared with third parties. We're GDPR and CCPA compliant out of the box, with audit-trail support for the conditional T&C checkbox extension.

We published detailed comparison pages for the most popular alternatives. Short version: Cartylabs bundles cart drawer + checkout extensions + post-purchase upsells in one app, runs on Shopify's native Checkout Extensibility (no script bloat), starts at $4.99, and saves most stores $150-200/mo by consolidating their app stack.

Trusted by 1,000+ Shopify stores, 4.9★ average rating, 99.99% uptime, and a 7-day free trial with no credit card. If you don't see ROI in the trial window, there's zero risk to uninstall.

All data stays in Shopify and is exportable anytime. Storefront features (cart drawer, sticky bar) keep working for 30 days even if the service is unavailable, giving you time to migrate. We're committed to this space long-term.

No. Cartylabs' AI surfaces products customers are likely to want based on actual behavior, not blast every offer. Conversion rate on AI upsells is 8-12% (vs 2-3% for generic widgets). Stores that disable the feature later say the issue wasn't spam — it was missing out on revenue.

Most stores see a 5-10% AOV lift within 7 days, and 15-20% within 30 days. Post-purchase upsells average +22% AOV lift. At $4.99/mo, the app pays for itself with a single extra order.
