Finance trusteeship consolidates billing from linked accounts under a main account. This topic covers the billing rules, billing cycle transitions, and account constraints that apply when trusteeship is active.
Rules for linked accounts
The main account pays for all subscription and pay-as-you-go bills incurred by linked accounts during the trusteeship.
Resource availability in linked accounts depends on the main account's balance. If the main account has insufficient funds, all resources in linked accounts become unavailable.
The main account manages and pays for all fees incurred by linked accounts.
All invoices for linked accounts are issued to the main account.
Linked accounts share the discounts and coupons of the main account.
After trusteeship is established, the existing balance of a linked account is not transferred to the main account. The linked account's existing balance can still be used to pay bills generated before the trusteeship was established.
The Cost Analysis feature is not available for linked accounts.
Trusteeship rules
After trusteeship is established, low-balance and high-bill alerts are sent only to the main account, not to linked accounts.
The main account's coupons and discounts apply to fees incurred by linked accounts, except AliTelecom fees. Linked accounts can still use their own coupons for AliTelecom.
After trusteeship is established, the main account takes over billing starting from the next billing cycle. Bills in the current billing cycle remain the responsibility of the linked account. For example, if bills are generated daily and trusteeship is established on March 10, the linked account pays for March 10's bills and the main account pays starting March 11. This logic applies to all billing cycles (hourly, daily, weekly, or monthly).
Coupons held by a linked account cannot be shared with other linked accounts of the same main account.

When you establish or modify a trusteeship, both the linked account and the original main account must have no unpaid bills. Check for unpaid bills by viewing the Unsettled status on the Billing Details tab of the Bill Details page.
If unsettled bills exist, the linked account or original main account pays those bills in the current billing cycle. The new trusteeship takes effect in the next billing cycle.
If no unsettled bills exist, the trusteeship takes effect in the current billing cycle. The linked account or original main account pays for bills generated before the trusteeship. The new main account pays for bills generated after.
Resource ownership transfers to the main account once trusteeship is established. After you remove the trusteeship, ownership returns to the linked account. Transferred resources remain valid for their remaining validity period but have no monetary value — downgrading these resources does not issue a refund for the remaining period.
The main account and linked accounts must belong to the same enterprise. After trusteeship is established, you cannot change the real-name verification information of the accounts. To change this information, remove the trusteeship first.
A main account can establish trusteeship with up to 300 linked accounts.
