You can set up an Out of Stock alert in Zoho Books, which will automatically trigger a warning message once your stock drops below zero. To set up the alert:
Enable the Show an Out of Stock warning when an item’s stock drops below zero checkbox.
Insight: Enabling this option will only display a warning while you’re creating a transaction. However, you won’t be restricted from creating the transaction.
Click Save to proceed.
Note: The warnings are shown only when you create transactions that will affect your stock (either on creating an invoice or a vendor credit, depending on your mode of stock tracking).
