OverlayIQ

OverlayIQ protects your profit margins by stopping repeat customers from abusing discount codes meant for first-time buyers. When customers create new accounts using email aliases, reformatted shipping addresses, or incognito browsing to reuse welcome discounts, each abuse cuts into your new-customer acquisition budget. This app detects these patterns and blocks unauthorized discount usage automatically at checkout before payment is captured. Buyers see a clear rejection message while you keep your margins intact without dealing with chargebacks. The app links guest checkouts and multiple accounts to a single master identity, catching alias-account abuse in real-time. Choose between Relaxed, Balanced, or Strict enforcement modes to match your store's needs and stop first-time-customer codes from being exploited by repeat buyers.
