OversellCap

Keep selling at zero stock — but never past your limit. OversellCap auto-stops at your cap.

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. Stopping protection restores your original Shopify settings. No customer data is stored.

• 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
• Bulk adjust limits for selected products or the whole store in one go
