Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureShopify tracks inventory per variant, so a 200-unit run must be split across variants before you know what sells. Set one number instead and every variant draws from the same inventory pool. When the cap is hit, the product locks and shows sold out. It counts units from real orders, not your Shopify stock, so the cap holds during a rush and even when inventory is untracked.
Install once and control product sales periods directly from Shopify Metafields. No theme edits or custom development required. Sales Guard uses Shopify Metafields to manage product availability automatically. Configure sales windows for products or variants, send launch and back-in-stock notifications, schedule sale prices, and prevent purchases outside the sales period.
- One limit across every variant. Sell every size and color against the same cap.
- Three limit types: total quantity, time window, or daily auto-reset.
- Sells out at cart, checkout, and payment step. Three-layer enforcement.
- Set when the drop ends, then mark it sold out or hide it from your store
- 販売期間を設定するだけで、期間外の注文を自動で防止
- チェックアウト時に自動制御されるため手動対応が不要

How Shoplist compares apps
Store counts come from Shoplist’s crawl of Shopify storefronts, which detects the apps each store runs; they are as of Oct 13, 2026. Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
