# CM Rules

## CM Rules

This feature allows you to add or delete occupancies that would not be handled automatically by the channel manager.

Rules are defined as follows:

1. set the period of application of the rule
2. select the starting room, the one from which the rule is derived ![](https://guides.netstorming.net/en/user/pages/05.hotel-direct-contract/11.cm-rules/Screenshot%20(160).png)
3. set the rule to be applied, defined as a percentage or amount ![](https://guides.netstorming.net/en/user/pages/05.hotel-direct-contract/11.cm-rules/Screenshot%20(161).png)
4. consider that when the starting room is selected, it is no longer enabled for the rule

**Example 1**: given the twin room rate received through channel manager, the hotel will allow triple room for 10 euros more ![](https://guides.netstorming.net/en/user/pages/05.hotel-direct-contract/11.cm-rules/cm%20rules1.png)**Example 2**: the hotel also has single rooms but they are 35 percent over the price of an adult in twin ![](https://guides.netstorming.net/en/user/pages/05.hotel-direct-contract/11.cm-rules/cm%20rules2.png)

**Example 3**: given the twin room rate received through channel manager, it is necessary to calculate: 35% for third adult, 25% for child (-75%), 0% (-100%) for infant ![](https://guides.netstorming.net/en/user/pages/05.hotel-direct-contract/11.cm-rules/Cattura__.PNG)

It should be noted that CM rules apply only to tariffs; for occupancy management, you need to ask the channel manager to send it in the Allotments Flex tab.
