About this app
Set one number, say 200, and every size and color sells against that single cap. The moment it's hit, the product locks and shows sold out. It counts units from real orders, not your Shopify stock, so the cap holds even during a rush and even when inventory is untracked. Use it for hyped limited drops, fixed-run editions, daily restocks, timed releases, and made-to-order shops that can only take so many.
