Customers can change orders that have been placed for DMS controlled outlets (subject to constraints you place on notification periods or cut off times).

> ℹ️ **Note**
> ℹ️ 
> ℹ️ Customers cannot modify orders that have been rationed or restricted. However, they can still cancel the order.

# Changes to Operating Orders

For an *Operating* order, a customer can:

- Change the finish time
- Change the flow rate
- Immediately stop an order with an emergency stop.

# Changes to Pending Orders

For a Pending order, a customer can:

- Change the start time
- Cancel the order

For other changes, cancel the order and place a new one.

# Emergency Stop

At a DMS controlled outlet, customers may have the option to stop an operating order immediately with the **Stop** button. This will change the order finish time to NOW and the order will stop. You will only be charged for the water that was delivered.

> ℹ️ **Note**
> ℹ️ 
> ℹ️ If you do use the **Stop** button to stop an order, call and tell the planner what has happened. In some cases, a water authority may halt any existing future orders as a precaution after an emergency stop.
