Getting started
How does Fast Checkout Sales Bundle work?
Fast Checkout Sales Bundle by Cartylabs ships every cart-conversion feature in one Shopify app: a slide-out cart drawer, sticky add-to-cart bar, AI upsells, free-gift rewards, and one-click checkout. Toggle on the features you want from your dashboard — they install instantly via Shopify's App Embed framework.
How long does setup take?
About 2 minutes. 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.
Will it work with my Shopify theme?
Yes — Fast Checkout Sales Bundle is tested against 150+ Shopify themes including Dawn, Impulse, Prestige, Symmetry, Stiletto, and all popular Shopify Plus themes. If you hit any issue we'll integrate with your theme for free.
Does it work on mobile?
Yes — every feature is mobile-first. Cart drawer, sticky bar, rewards, and quick-buy buttons are designed for touch and tested on iOS Safari, Android Chrome, and every modern desktop browser.
Can I preview changes before going live?
Yes. Every change has a side-by-side preview ("WYSIWYG"). We still recommend a quick check on your live store after saving.
Is there a free plan or trial?
You can install free and try every feature. Paid plans start at $4.99/month with no setup fees and no contracts.
Cart drawer
How do I customize the cart drawer?
From the dashboard, open Cart Drawer → Style to control colors, fonts, spacing, and the layout of upsells and the rewards bar. Custom HTML/CSS is supported on Growth.
Can I trigger different actions when items are added?
Yes. Choose between: open the cart drawer, redirect to the cart page, or send straight to checkout. Configure per-feature in Button/Basic Settings.
Does the drawer support promo codes and auto-discounts?
Yes. Shoppers can enter codes inside the drawer, and Fast Checkout Sales Bundle surfaces auto-applied discounts as line items so the value is always visible.
How does the shipping bar work?
The shipping bar shows real-time progress toward free-shipping thresholds you define. Combine it with rewards milestones to unlock gifts and discounts as the cart grows.
Is the cart drawer mobile responsive?
Fully. The drawer adapts to mobile width, supports swipe-to-close, and is performance-tuned to keep your Lighthouse mobile score intact.
Upsells & cross-sells
How do AI upsells work?
Fast Checkout Sales Bundle analyzes cart contents, the shopper's browse history, and store-wide buy patterns to recommend the offer most likely to be added. You can also manually curate offers by collection, product, or rule.
What about Frequently-bought-together?
FBT bundles use co-purchase data to surface the products most often bought alongside what's in the cart, with a one-click add-all button.
Can I run post-purchase upsells?
Yes. Post-purchase upsells appear in Shopify's native checkout flow after payment is complete — adding revenue without risking the original conversion.
How do I track upsell performance?
The Analytics dashboard shows views, clicks, conversion rate, and revenue per upsell offer. Filter by date range, segment, or product to find what's working.
Can I show personalized discounts in the cart?
Yes. Trigger discount or gift offers based on cart value, item count, customer segment, or referrer.
Sticky cart & quick buy
How do I skip the cart page and go straight to checkout?
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.
What's the difference between sticky bar and sticky button?
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.
What is the mini cart badge counter?
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.
Does the browser-tab badge work in every browser?
It works in Chrome, Edge, Firefox, and Opera (~81% of global traffic). Safari and IE don't allow favicon updates after page load.
Why isn't my sticky button showing for one product?
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 and we'll integrate with your theme for free.
Billing & plans
How does the Growth plan pricing work?
$9.99/month flat, plus $0.05 per order up to 2,000 orders per cycle. After 2,000 orders, additional orders are free.
Can I cancel anytime?
Yes. Cancel from your Shopify admin in one click. Billing stops immediately — no contracts, no cancellation fees.
How am I billed?
Through Shopify's native billing API. Fast Checkout Sales Bundle appears as a line item on your regular Shopify invoice.
Can I change plans later?
Yes. Upgrade or downgrade anytime; the change takes effect on your next billing cycle.
Do you offer refunds?
We review refund requests case-by-case. Email support@cartylabs.com with your shop URL and we'll respond within one business day.
Performance & security
Will Fast Checkout Sales Bundle slow down my store?
No. The app loads asynchronously via Shopify's App Embed and is performance-budgeted — most stores see no measurable Lighthouse impact.
Is my customer data safe?
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.
What's your uptime?
99.99% over the last 12 months. Status is published in real time at our status page.
Do you support Shopify Plus?
Yes. Fast Checkout Sales Bundle is compatible with Shopify Plus features including B2B catalogs, customer accounts, Markets, and checkout extensibility.
Will this work with my custom storefront or headless Shopify?
Fast Checkout Sales Bundle integrates via Shopify App Embed, which works 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 tech stack and we'll review.
Does it track cookies or use third-party pixels?
No. Fast Checkout Sales Bundle does cookie-free analytics out of the box using Shopify's first-party data. You control what data you collect and we never share data with third parties.
Common concerns
What's the difference between Fast Checkout Sales Bundle and [competitor]?
We published detailed comparison pages for the most popular alternatives. In short: Fast Checkout Sales Bundle ships more features on lower-tier plans (AI upsells, rewards bar, sticky cart all start at $4.99), has 2-minute setup, and saves most stores $150-200/mo by consolidating their app stack.
Why should I trust Fast Checkout Sales Bundle over established competitors?
We're backed by proven operators, trusted by 1,000+ Shopify stores, maintain 99.99% uptime, and offer a 14-day free trial on the Cart Drawer with no credit card required. If you don't see ROI, there's no risk to uninstall.
What if Cartylabs shuts down?
All data stays in Shopify and is exportable anytime. Features you enable (cart drawer, sticky bar) will continue working for 30 days even if the service is unavailable, so you have time to migrate. We take this seriously and are committed to this space long-term.
Will the AI upsells feel spammy or hurt my brand?
No. The AI is designed to surface products customers are likely to want based on their actual behavior, not blast every offer. The conversion rate on AI upsells is 8-12% (vs 2-3% for generic widgets). Stores that disable the feature later say the problem wasn't spam — it was missing out on revenue.
How long does it take to see ROI?
Most stores see a 5-10% AOV lift within 7 days of going live, and 15-20% within 30 days. At $4.99/mo, the app pays for itself with a single extra order per month.
Do you offer discounts for annual billing?
Not currently, but we're exploring it. Reach out to support@cartylabs.com if volume discounts or custom pricing would help your decision.
Can I test this on a staging environment first?
Yes. Install Fast Checkout Sales Bundle on your development store and toggle on the features you want. We recommend a quick preview on your live store once configured to ensure theme compatibility.
