At Kisi we try to make our billing as fair and transparent as possible.
This lead us to the decision to always aiming for calculating month-to-month based volumes even on yearly or multi-yearly licenses. So you only pay for what you use.
This is why yearly or multi year licenses are handled as credits. This means that although you are purchasing multiple years in advance, what you are receiving is a license credit for the desired volume and time. This allows you to stay more flexible: If you end up using less volume than planned, your credits will last longer. If you are ramping up you can use your credits without having to purchase a new license immediately.
We've introduced this policy on all our standardized plans as of August 2020. If you have any questions please contact email@example.com
