Billing details

Aiven services are billed by the hour, you only pay for the services that are running. No extra charges are applied when a service is migrated between clouds or the service type is changed. The new hourly pricing takes immediate effect on such changes.

The default billing method for Aiven usage is a credit card charge (using Stripe as the credit card processor) at the end of a calendar month. MasterCard, Visa and American Express are among the supported credit card types. The final charges will also include the applicable VAT for non-business entities within the European Union.

All Aiven prices are set in US Dollars. Clients can choose to be billed in Euros, in which case the total service bill in US Dollars over one calendar month is converted to Euros at the end of the month and an invoice is issued for that sum. Official pricing is always in US Dollars and any pricing displayed in Euros is based on estimates.

Custom pricing for up-front payment of a fixed term and invoicing are available for customers based on approval by Aiven. Please contact for a custom quote and more details on payment methods.
