Invoicing clients

Harvest Project + Task
Core Retainer -> Paperwork & Invoicing
Decision from 12/20 mtg
Each client project should now have a “paperwork & invoicing” task within the planned maintenance project. This category is non-billable; clients do not pay for paperwork & invoicing.
We don’t have this yet and it’s a problem since there is no other place for this kind of time o go. This category needs to be added to the core retainers.
