Tenant-level Limits

Last updated

Zuora is a true multi-tenant SaaS based application. As such, Zuora enforces a number of tenant-level limits to ensure that no one tenant monopolizes shared resources. This article describes these tenant-level limits.

Need higher thresholds?

If your business requires higher thresholds, please contact Zuora Global Support. We can work with you to evaluate your specific requirements.

Amendments per Subscription

Zuora recommends that you create no more than 100 amendments on a subscription to ensure high performance of the subscriptions. The limit of amendments allowed on a subscription is 1000. However, if you create more than 100 amendments, the performance may be severely degraded, depending on the products and charges set up in your subscription.

The limit of subscriptions allowed on an account is by default 12,000. However, if you have overridden the value of this limit for your tenant, the value will remain per your configuration.

If the renewal term period of the latest version of the subscription is Day or Week, the limit of amendments allowed on a subscription is 100.

Account	Number of Subscriptions	The default maximum number of subscriptions allowed on an account is 12,000. However, if you have overridden the value of this limit for your tenant, the value will remain according to your configuration. Zuora can increase the limit of subscriptions per account upon request. To increase the limit, see Zuora’s Performance Booster and Performance Booster Elite offerings. Note that the method that Zuora uses to calculate the number of existing subscriptions on an account is explained as below. When you create a new subscription on an account, the start and end dates of the subscription determine a time frame. When calculating the number of existing subscriptions on the account, Zuora only counts in those existing subscriptions that have a time frame that overlaps with the new subscription to be created. The time frame of an existing subscription is also determined by the start and end dates of the existing subscription. For an evergreen subscription, this time frame is without an end date.
