Billing : License costs reimbursement

[Phil Janssens]

Hello,

I have a question regarding billing of Trello licenses.
We need to renew our licenses but in parallel we are also migrating to Azure DevOps following a corporate policy.

My question (and assumption) is that if we would stop Trello after let's say one month, the remaining costs would be reimbursed. So if the cost for a year is 1200$ and we cancel the license after a month we would reimbursed 1100$. Is that a correct assumption ?

If that would not be the case, is it possible to order and if needed extend licenses per month ?
