Rules of using a linked account
After a trusteeship is established, the following rules apply:
During the validity of the trusteeship, the master account is obligated to pay for the orders and pay-as-you-go bills of the linked accounts.
The availability of resources within linked accounts is determined by the available balance of the master account. If the balance of the master account is insufficient, all resources of the linked accounts become unavailable.
The master account manages and pays for all fees that the linked accounts incur.
The invoices for all linked accounts are included in the invoice for the master account, and the master account issues the invoices for the linked accounts.
The discounts and coupons of the master account are used to offset the fees of its linked accounts.
After the trusteeship is established, the available balance of a linked account is not transferred to the master account. The balance of the linked account can still be used to pay for the bills that are generated before the trusteeship is established.
The Cost Analysis function is not available for the linked accounts.
Rules of using the trusteeship
After a trusteeship is established, User Center no longer sends low balance alerts and high bill alerts to linked accounts. User Center sends these alerts only to the master account based on the consumption and available balance of the master account.
The coupons and discounts of the master account are used to offset the fees that linked accounts incur, except for the fees related to AliTelecom. The coupons of linked accounts can still be used to offset the fees for AliTelecom.
After a trusteeship is established between the master account and linked accounts, only bills in the next billing cycle are managed by the master account. For example, the bills for a service are generated every day. If a trusteeship is established between the master account and a linked account on a specific day, the bills on that day are still managed by the linked account. On the next day, the bills are managed by the master account, and the coupons of the master account can be used to offset the fees of the linked account. This billing logic applies to services whose bills are generated every hour, minute, week, or month.
The coupons of a linked account cannot be shared with other linked accounts of the master account.
When you try to establish or modify the trusteeship with a linked account, the trusteeship is established or modified only if the linked account or the original master account has no unpaid bills. To check whether your account has unpaid bills, you can view bills in the Unsettled state on the Consumption by Bill tab of the Bill Details page in the Billing Management console.
If the linked account or original master account has bills in the Unsettled state, the linked account or original master account pays for all fees of the service that incurred these bills in the current billing cycle. The new or modified trusteeship takes effect in the next billing cycle.
If the linked account or original master account has no bills in the Unsettled state, the new or modified trusteeship takes effect in the current billing cycle. The linked account or original master account pays for bills that are generated before the trusteeship is established or modified. The new master account pays for bills that are generated after the trusteeship is established or modified.
The ownership of the resources will be transferred to the main account once the trusteeship established. After you remove trusteeship between the main account and the linked account, the resource ownership will back to the linked account. The transferred resources are still valid within the remaining validity period, but have no monetary value. If you downgrade configurations of these resources, the monetary value of these resources for the remaining validity period is not calculated, and no refund is provided.
The main account and linked accounts must belong to the same enterprise. After trusteeship is established between the main account and linked accounts, you cannot change the real-name verification information of the accounts. If you want to change the real-name verification information of the accounts, you must remove the trusteeship between the main account and linked accounts.
Trusteeship can be established between a master account and up to 300 linked accounts.
