The seat balance reflects the latest number of seats in use for a customer, per seat metric. For example, a customer may have a seat balance of 120 Admin seats. The next day 5 new Admin seats are added, 1 is removed. The new seat balance is 124 Admin seats.
If multiple seat metrics are defined for a customer, the balance column will show the total across all seat metrics. Expand the customer view to get a breakdown by seat metric.
