Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureOut-of-stock sizes = lost sales. Stop missing revenue by keeping all sizes available on your product pages. CutSizeGenie lets you sell unavailable sizes using smart size mapping (S→M, L→XL) and virtual inventory logic. No coding required. Auto-sync across locations, improve product availability, support variant availability, and reduce stock issues.
When a variant sells out, Shopify stops the sale. Substitutions keeps it buyable and ships a backup you approved, so the order goes out instead of being lost. The app scans your catalog and uses AI-assisted matching to suggest a backup for each sold-out variant: the same item from a new production run, in another pack, or as smaller sizes that add up. Turn one on in a click.
- Help Out Of Stock traffic to buy Sizes/Variants even when they're unavailable
- Shows all sizes as available on PDP by using virtual fallback inventory.
- Tracks and logs every virtual sale and stock adjustment for full accuracy
- Improve PDP conversions with automatic size fallback and variant mapping
- Automatic Product Substitution: replace out of stock products automatically.
- Customizable Sequence: order alternative SKUs according to your preferences.
- Real-time Inventory Sync: avoid offering unavailable items as substitutions.
- Detailed Logs: track your substitutions and adjust to maximize sales.
