You can set one or more stock totals for each resource. Each stock total specifies the total inventory of the resource for a particular time period. For example, if your school has five vans in 2019, but plans to purchase two more vans by January 15, 2020 you might have the following stock totals:

Resources you’ve assigned stock totals to are automatically decremented when assigned to events. For example, if a scheduler assigns one van to an event occurring from 10:00 am to 3:00 pm on October 21, 2019, that assignment reduces the number of vans available on that day and time period to four. The stock total remains unchanged, but the available inventory is decremented.

You don’t have to assign stock totals to resources. If you don’t, the resource is not automatically decremented when assigned. For example, if you want to track the use of a resource that your school rents rather than owns, such as portable toilets, you might create a resource for it, but not enter a stock total. You might also decide you don’t want to decrement a resource for other reasons; for example, you want schedulers to be able to request a certain number of muffins for an event, but it may not make sense to have a muffin “inventory” decremented by that number when assigned.
