Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureShoppers add a one-of-a-kind item to their cart, race to checkout, and find it already sold. HoldCart places a genuine inventory hold the moment an item is added, so the unit is actually reserved while they check out, then auto-releases back to stock when the timer ends. It is not a fake countdown or manufactured urgency — it is a real hold with a real timer.
OversellCap adds a hard, automatic oversell limit to variants that keep selling when out of stock. Set a per-variant cap: after stock reaches zero, sales continue up to your limit, then the variant is instantly marked Sold Out. Restock it and selling resumes automatically. Extras include an early-cutoff buffer, a tamper watchdog, email alerts, bulk limit adjustments, and activity history.
- Real inventory holds — items are genuinely reserved at add-to-cart, not faked
- Fail-safe by design — if the app fails, your checkout keeps working
- Honest countdown — shoppers see a real timer backed by a real hold
- Automatic release — holds expire and return to stock on their own
- Hard oversell cap — set exactly how many extra units can sell at zero stock
- Auto-stop at the limit and auto-resume after restock, no manual work
- Early-cutoff buffer covers bursts of simultaneous checkouts
- Watchdog restores your selling policy if another app changes it
