Add stock urgency messaging under the variant picker. "Only [N] left in [size/variant]" when stock is low. Updates when switching variants.
Want more control? See the expanded prompt ›
On the product page, add a stock urgency message under the variant picker. Show 'Only N left in size X' when stock drops below 5, in red text. Update live when the user switches variants.
- Shows only when stock drops below 5 (configurable).
- Updates live when shoppers switch variants.
- Hidden for products with unlimited inventory.
- Color and threshold customizable per prompt.
What you're trying to do
Real scarcity beats fake scarcity every time. If a customer sees 'Only 2 left' and it's actually true, they buy faster. If they see it on every product, they stop trusting your store. Variant-aware urgency only shows up when stock really is low.
Things to watch out for
- Honesty: only triggers when stock is genuinely low. Fudge never fakes it.
- Unlimited inventory: the message hides for products without inventory tracking.
- Pre-orders: the message can read 'X arriving in 2 weeks' for backorder products.
- Threshold: below 5 by default, and you can set it per product or category.
How Fudge does it
Fudge duplicates your live theme into a draft, edits the relevant template (product page or cart) with the changes your prompt requires, and tests against your real product data. Everything starts in draft — preview on any product or in the cart, tweak any detail, and publish when you're ready. Your live store stays untouched.
Why real variant-level urgency builds trust
“Only N left in size M” urgency works when it’s real. Fake “Only 3 left” on every product erodes trust permanently; real variant-level urgency, read from your inventory each time the page loads, drives conversion without the trust cost.
When this is worth building
Build variant-level urgency for any apparel or sized-variant catalog. Skip for unlimited-inventory categories where the messaging doesn’t fit.
What makes one great
- Threshold below 5 (configurable) — only shows when actually low.
- Updates live when shoppers switch variants — accurate per choice.
- Hidden for products without inventory tracking — graceful fallback.
- Pre-orders / backorder variant — “Arriving in 2 weeks” instead of “Out of stock.”
Pair this with sticky add-to-cart bar and return rate analysis.
Fudge builds this with its store editor.
