Why merchants use it

A buy button that never leaves the screen.

Shoppers lose interest when they have to hunt for the Add to Cart button. Keep it pinned, on-brand, and one tap away - and watch fewer carts slip through the cracks.

Always within reach

A persistent Add to Cart bar follows shoppers down the page, so the buy action is never more than a glance away - no scrolling back to the top.

Total visual control

Colours, gradients, fonts, shadows, borders, opacity and button styles. Match your brand exactly with a live preview - no code, no theme edits.

Smart show triggers

Show the bar on scroll (when the original button leaves the screen), always on load, or after a timed delay. Add a dismiss button with your own close behaviour.

Drag-to-arrange layout

Reorder image, title, price, variants, quantity and the button by dragging. Toggle any element off, and anchor the bar to the bottom, top, left or right.

Built for mobile

A compact mobile layout with its own breakpoint, plus separate Show on desktop and Show on mobile switches. Smooth slide, fade or bounce animations on every device.

Variants & quantity, inline

Let shoppers pick a size or colour and set quantity right from the bar - dropdowns, swatches, radios or rectangles. Then keep them on the page or send them straight to the cart or checkout.

Set up in minutes

From install to live bar in four steps.

Configure it once in a visual dashboard - the app does the storefront install for you.

1

Install the app

Add Sticky Add to Cart from the BigCommerce App Marketplace - no theme files to touch. Then start your 7-day free trial from the dashboard.

2

Configure your bar

Use the Styling, Layout and Behavior tabs to design the bar. Every change updates the live preview instantly, on desktop and mobile.

3

Preview it live

Check the bar on a simulated product page, switch between desktop and mobile, or open a full-page preview before you publish.

4

Save & go live

Hit Save. The app installs the bar across all your product pages automatically - live in minutes, no developer required.

Make it yours

Three tabs. Endless looks.

Everything is configured from one dashboard with a real-time live preview - so the bar feels like a native part of your storefront, not a bolted-on widget.

  • Style every detail.
    Gradients, fonts, shadows, button styles, image, variants and quantity.
  • Arrange the layout.
    Drag to reorder, hide elements, and anchor the bar to any edge.
  • Control the behaviour.
    Triggers, animations, cart redirects, success messages, mobile rules and z-index.

Styling Pixel-perfect to your brand

Background and gradient, typography and colours, four button styles, product image, variant selectors and the quantity picker.

Layout Position & arrangement

Drag elements into the order you want, toggle any of them off, set full or contained width, alignment and spacing - bottom, top, left or right.

Behavior When & how it shows

Scroll, always-on or delayed triggers, entry and exit animations, success notifications, redirect to cart or checkout after adding, and dedicated mobile settings.

Made for

Wherever shoppers scroll, keep them buying.

The longer your product page, the more a sticky bar earns its place.

Considered purchases

Long, detailed product pages for higher-ticket items keep the buy button pinned while shoppers read specs, reviews and FAQs.

Mobile-first stores

On small screens the original button scrolls away fast. A compact sticky bar keeps checkout one tap away the whole way down.

Rich, scrollable pages

Image galleries, descriptions, related products - whenever your product page is tall, the bar removes the friction of scrolling back up.

FAQ

Questions, answered.

How does the bar get onto my product pages?

When you click Save, the app automatically installs its storefront script on your store via the BigCommerce Scripts API - there are no theme files to edit. While your free trial or plan is active, the bar appears on all product pages. To pause it, switch off Show on desktop and Show on mobile in the app; to remove it, uninstall.

Will it match my store's design?

Yes. The Styling tab gives you full control over background (solid or gradient), typography, colours, button style, shadows, borders, the product image, variant controls and the quantity picker. Set the font to Store Default to inherit your theme's font automatically.

When exactly does the bar appear?

You choose. Show it on scroll once the page's original Add to Cart button leaves the viewport (recommended), always on page load, or after a time delay. You can also set a scroll threshold and an optional close button.

Does it work on mobile?

Fully. There's a compact mobile layout, a configurable mobile breakpoint, and separate Show on desktop and Show on mobile switches - plus smooth entry and exit animations.

Can shoppers choose variants and quantity from the bar?

Yes. Add the variant selector (dropdown, swatch, radio or rectangle list) and a quantity picker (stepper, dropdown or number input) to the bar, so customers can configure and add to cart without scrolling. After adding, you choose whether they stay on the page or go straight to the cart or checkout.

How do pricing and the free trial work?

It's $5/month after a 7-day free trial (one trial per store). Start the trial from the plan card in the app - Stripe Checkout asks for a card, and you're not charged until the trial ends. Cancel any time from Manage billing; the bar keeps running until the end of the period you've paid for. Uninstalling cancels straight away.

What permissions does the app need?

Content (to install the storefront script that renders the bar), Products (to show the right title, price, image and variants - the app never changes your catalogue), Carts (for the add-to-cart flow) and Storefront API tokens (to look up the current product securely). It does not touch your orders or payment data.
