The Premium seats are paid at a monthly rate of $125 per person per month, equivalent to $100 per person per month at an annual rate, and the two tranches for the Standard seats are $25 and $20, respectively。

Premium seats include five times the Standard, remove the five hours limit and switch to a fixed weekly replacement cycle. The same Businss workspace allows for a mixed allocation of the Standard and Premium seats, with administrators able to upgrade and reallocate their seats and have a uniform view of usage and expenditure limits。
