Reservation

In the Storage tab, you will be able to allocate a storage unit for the job. To look up the available storage units, choose the Storage Type, and required date range and click on the Search button. 

The search results will list all storage units available for that date range. You can then click on the Reserve button to allocate the storage unit for the job. To edit or delete an already reserved storage unit, click on the three dots and choose the required option. If a storage unit was already reserved for this job when it was an opportunity, that storage unit will be shown and you don't have to search and allocate again.

Invoice for Storage

You can create a separate invoice for the storage part of the job. To do this you can use this section. If there was an estimate in the opportunity of this job, then that will get converted to a Storage invoice. However, the current limitation is that you can create only one storage invoice per job and you will not be able to generate and automatically send periodic invoices like weekly, monthly, quarterly etc.
