Non-Billable Hours
Non-billable hours are hours worked that cannot be charged to a client: internal meetings, admin, training, business development, proposals, and project overruns you chose not to invoice. Every guide to this subject treats non-billable time as a problem to minimise. That framing causes two expensive errors. It leads firms to price as though non-billable time does not exist, which understates the break-even rate by around 60%.
