Taruni used CutSizeGenie to recover size-led demand.

When S/L were frequently out of stock on Shopify while M/XL had inventory, conversion dropped. CutSizeGenie helped Taruni keep key sizes available using controlled size mapping + thresholds.

What changed
  • More sizes showed as in-stock on PDP
  • Fewer “my size sold out” drop-offs
  • Better efficiency on paid traffic
  • Ops got clean logs for alterations
How it was implemented

S borrowed from M, L borrowed from XL on selected collections. Mappings were enabled only where tailoring/cut-size workflows were feasible.

Thresholds ensured jump sizes stopped sharing below safe limits. Caps controlled maximum virtual allocations so fulfilment remained practical.

Virtual orders were logged for operations so the warehouse knew which source size was consumed and what to pick/alter. Clear visibility reduced confusion.

Note: The ₹10L+ figure is an observed outcome for Taruni and isn’t a guarantee for every store.

Out-of-stock sizes silently kill PDP conversion.

In fashion, customers buy when their size is available. But production reality often stocks jump sizes (M/XL). When S/L shows OOS on Shopify, customers bounce — even though your warehouse could alter a nearby size.

📉
Lost revenue on hero products

1–2 sizes sold out → full-price demand disappears, even if nearby sizes exist.

💸
ROAS waste on paid traffic

You pay for clicks. Users land on PDP and exit due to size OOS.

Manual fixes don’t scale

WhatsApp + calls + manual stock edits break at scale.

🧮
Inventory looks worse than reality

Catalog appears half-stocked even when warehouse can fulfill via tailoring.

CutSizeGenie is not meant for regulated categories (food, medicine, perishables) where substitutions/alterations are not allowed.

Size mapping + virtual inventory in 3 steps.

CutSizeGenie plugs into Shopify products, variants & inventory — then manages virtual restocking and safe consumption in the background.

Step 1
Define your mapping logic

Example: S borrows from M, L borrows from XL — by product/collection/category.

Step 2
Virtual restock when target hits 0

If S is OOS, CutSizeGenie checks M stock and pushes controlled virtual stock to S.

Step 3
Orders consume real stock safely

When S sells, M is decremented. Orders are logged for ops and audit.

Built to avoid overselling.

Virtual inventory stays under your control: thresholds, caps, exclusions, and location-aware behavior.

Minimum stock thresholds

Stop sharing when the source size falls below a safe minimum.

Max-share caps

Cap how many units can be virtually allocated to prevent aggressive pushing.

Selective enable/disable

Enable only alteration-friendly styles; exclude anything risky.

Location-aware behavior

Control how virtual inventory behaves across Shopify locations.

CutSizeGenie works via Shopify Admin APIs. No theme snippet installs. No fragile Liquid dependencies.

Quick answers.

For AI + SEO, the full FAQ page has deeper questions and keyword coverage.

Will this oversell my inventory?

No — thresholds and max-share limits stop virtual restocking automatically.

Do I need theme edits or Liquid?

No theme edits. It works at the inventory layer via Shopify APIs.

Is it good for ethnicwear and occasionwear?

Yes — especially where tailoring/cut-size flows are part of operations.

Can I turn it off easily?

Yes. Disable mappings/rules or uninstall — Shopify returns to default behavior.

Ready to turn sizing reality into revenue?

Install CutSizeGenie, configure mappings once, and let virtual inventory quietly recover demand that was slipping away because of out-of-stock sizes.

All billing happens via Shopify. Results vary by catalog, traffic, and operational capacity.
