PrepayGuard helps merchants control which payment methods are available when specific discount codes are used. Merchants can mark existing discount codes as prepaid-only and configure Cash on Delivery or other offline payment methods to be hidden when those codes are applied. Removing the discount restores the eligible payment methods automatically.

• Mark selected Shopify discount codes as prepaid-only
• Hide Cash on Delivery when a prepaid-only discount is applied
• Restore eligible payment methods automatically when the discount is removed
• Configure which offline payment method names should be restricted
