A seat that is added or removed mid-cycle is prorated by the number of days left in the
current billing cycle, so a workspace only ever pays for the days a seat was actually available to
it. Nothing waits for the next invoice, and nothing is rounded up to a whole month.
The formula is the same in both directions:
amount = seat price for the period
x (days remaining in the period / total days in the period)
Days remaining are counted from the day the change takes effect up to but not including the first
day of the next period. The seat price used is the one on your current plan, before any annual
discount is applied to the workspace as a whole.
Adding a seat raises a charge for the remaining days. On a monthly workspace that charge is
added to the next invoice rather than taken immediately, so a workspace that adds and removes
people through the month settles once.
Removing a seat stops it immediately, and the identical day-count is used to put a money value
on the unused remainder of the cycle for that seat — the days your agency paid for in advance
and will not now use. That value is what any adjustment for the removed seat is worked out from;
this page sets out how the figure is reached and does not decide whether an adjustment is made.
Cancelling the whole subscription mid-cycle is day-counted the same way, seat by seat, across
every seat on the workspace.
Worked example, on a monthly plan at $24 a seat, in a 30-day period: a seat that comes off with 10
days remaining is valued at 24 x (10 / 30) = $8.00. Two such seats come to $16.00, and so on.
An annual workspace is day-counted against the twelve-month term the same way, so a seat that comes
off after four months is valued at eight twelfths of that seat's annual price.
Where an adjustment is made, it appears on the invoice as its own line, with the date the change
took effect and the number of days it was calculated over.
