A stock alert sets expectations and adds gentle urgency. Add the Stock alert element from Insert → Shopify → Product, alongside Title, Price, and the buy buttons. It reads inventory from the connected product.
Default behavior
The preset shows a warning row — an icon plus the text "Limited availability, stock left:" followed by the remaining quantity. It's set to appear only when available inventory falls below a threshold (10 by default), using a conditional on the product's available quantity.
Customize the copy, colors, and typography in the Design panel, and rearrange the child Text and Icon layers in Layouts & layers while keeping the inventory connection intact. Place the alert near the buy box — below Price and above the add-to-cart Button — so shoppers see availability before they buy.
Custom stock messaging
To go beyond the preset, build your own messages with Text elements that use the product's available-quantity value and conditional visibility:
Show urgent copy when inventory is below a threshold you choose.
Show "Out of stock" when inventory reaches zero, and hide the add-to-cart Button at the same time.
Conditional visibility rules can key off the product's available quantity and its Available for sale state.
In product cards and grids
On Product card tiles in a collection grid, a compact badge reads better than a full sentence. Add Stock alert inside the repeated card, or use a Text badge with a conditional visibility rule. Keep the copy short — "Sold out" or "Low stock".
Product vs. cart
The Stock alert element reflects the product's inventory, not what's in the cart. For messaging that responds to cart contents, use cart elements and a Repeat on cart-items repeater instead. See Build a cart drawer.
