i also have a low level stock warning appear, you can set this to any level you want, for testing i have it set to 5 so when an order is added to the ticket if the stock level is less than 5 a warning message appears. Again, you can customise the type of message thats displayed eg display message action, ask question, ticket header etc, i like using the ask question with transparency on as below
from main pos screen add an order
if the order has a balance of less than 5 a warning message appears
