Can I change my plan anytime?

Of course you can! Just go to the billing page inside the account dashboard. If you change your plan mid-month, we'll prorate the cost.

What does 'per seat' mean?

Each member of your Organization occupies one 'seat'. You can add up to 5 users and manage who occupies those 5 seats in your Organization’s account dashboard.

Special pricing for non-profits?

Short answer, yes. To qualify, an organization must be non‑government, non‑academic and is required to send a proof that verifies its non-profit status.
