Is it possible to opt for a pool of licenses?
Yes, you can opt for a pool of licenses, which requires a minimum of 5,000 licenses per year. The price of each license is based on annual pricing. You will receive a notification once you use 80% of your pool.
As an example, after purchasing a pool of 5,000 licenses, every month, Zendesk draws the number of licenses used. In January, your team could use 300 seats leaving 4,700 seats free. In February, your team could use 100 seats, with 4,600 seats left. In March, your team headcount could increase, and you would use 1,000 seats. You would have 3,600 seats left until using the pool up.
To choose this option, contact Zendesk Customer Support.
