For pay-as-you-go resources, pay your bills promptly after they are generated to avoid service interruptions caused by overdue payments.
When to make a payment
You need to pay your bills promptly to avoid them becoming overdue. The payment timing depends on whether you are a user on credit control:
-
Users not on credit control: There is no fixed payment time. The system automatically deducts payment from your default payment method.
-
Users on credit control: Your contract with Alibaba Cloud specifies a payment term that determines the due date. This term is based on the settlement cycle (such as monthly or quarterly) and the payment period (such as a specific number of calendar or business days).
How to make a payment
The payment method depends on whether you are a user on credit control:
-
Non-credit-control users: If you link a bank card or PayPal account as your default payment method, the system automatically initiates a deduction when your accumulated pay-as-you-go fees reach a threshold. The threshold is USD 1,000 for bank cards and varies from USD 8 to 1,000 for PayPal, depending on the account. Additionally, at the end of each month, the system makes a single deduction for any bills that have not yet reached the threshold.
NoteModel Studio usage is billed separately and has its own independent "USD 1,000" threshold that is not combined with the general deduction threshold. Therefore, charges for Model Studio trigger a separate deduction when they reach USD 1,000, regardless of your spending on other products. Conversely, a deduction triggered by Model Studio usage does not affect the threshold calculation for other products.
-
Credit control users: If you top up your account balance through a bank transfer, you can enable the Automatic Write-off feature to have the system automatically settle your bills. If Automatic Write-off is disabled, you can manually select and pay bills on the Overview of Monthly Bill page.
When you use PayPal as your default payment method, the system triggers a pre-authorization check the first time you activate a pay-as-you-go product.
Automatic write-off
You can use the Automatic Write-off feature to automatically settle your bills. For users on credit control, go to the Billing Account > Account Settings section to check the status of this feature.

With Automatic Write-off enabled, the system automatically pays your bills after they are generated, as long as your account has sufficient available funds (account balance + credit limit - frozen amount > 0). The system deducts funds for payment in the following order of priority: stored value card → account balance.
If your available funds are insufficient, the system does not pay the bill automatically, and its status remains Not fully settled. You can top up your account on the Billing Account page. After you top up, the system automatically pays the unsettled bill.
Manual payment
Use this method when Automatic Write-off is disabled or when you need to make payments from different sources. You can pay bills individually or pay multiple outstanding bills at once from the console homepage.
-
Go to the payment page: You can pay a single bill, or pay multiple bills in a batch from the console homepage.
-
Pay a single bill: On the Overview of Monthly Bill page, find an Not fully settled monthly bill and click Pay Bill. In the side panel that appears, click Pay Bills.
-
Batch repayment from the homepage: In the Overview section of the Expenses and Costs console homepage, find Total Unpaid Amount and click Pay Bill. In the Repay panel, select one or more outstanding billing months (you can adjust the repayment amount for each row), then click Next. This lets you pay the outstanding bills for multiple months in a single operation.
-

-
Set the amount: Specify the Total Repayment Amount (defaults to the outstanding amount and can be modified) and the amount to deduct from your account balance.

-
Select a payment method: Select your account balance or a payment method linked to your account, such as a credit card. The system defaults to the last used method.
-
Complete the payment: The payment is deducted using the selected method, and the result appears on the page.
-
View the result: It takes about 30 minutes for the bill write-off status to update. You can refresh the page to check the status. Do not attempt to make the payment again during this time.
-
Manual payment temporarily disables the Automatic Write-off feature. The feature resumes automatically after the payment is complete.
-
If a user on credit control chooses to pay by billing cycle, selects Pay Bills, and selects the Use Account Balance to Offset checkbox, the system prioritizes using the account balance and any credit refund amount to cover the matching billing cycle. By default, credit refunds cannot be used for historical bills. The remaining amount is paid through an external payment method. This process ensures refund compliance and consistency between invoices and bills.
In multi-account enterprise scenarios where a finance sub-account can manage their own bills, you can use Unified Settlement and transfer payments.
View payment records
On the Overview of Monthly Bill page, in the Paid Amount column, click View Details to view the payment details for a bill. You can also click Deducted by Cash Coupons, Deducted Amount by Prepaid Card, or Payment Amount in the payment details panel that appears to view the detailed records for the corresponding payment method.

You can view payment records only for bills from January 2023 onwards.
FAQ
Why is my bill unsettled after enabling automatic write-off?
This issue usually occurs for one of the following reasons:
-
Insufficient available funds: If your available funds are less than or equal to 0, the system cannot complete the write-off, even if you have an account balance.
-
The monthly bill has not been generated: Alibaba Cloud officially generates monthly bills at 12:00 on the second day of the following month.
-
Special rules for users on credit control: Users on credit control may have special settlement rules as part of their agreement.
-
Stored value card restrictions: You can use a stored value card only within the month it is purchased. If a bill spans multiple months or you did not specify the card at the time of order, the system cannot use it for payment during automatic write-off.
-
A Unified Settlement task exists: If a Unified Settlement task has been created for the account, the system temporarily disables the Automatic Write-off feature. Funds are used for payment in the order specified by the settlement bill.
If you have ruled out all the preceding possibilities, go to Overview of Monthly Bill to check the specific billing cycle status and payment records.
Can I use refunds for past bills?
By default, you cannot use refunds to pay for bills from previous billing cycles. You can use them only for bills from the month of the refund and subsequent months.
However, direct customers of Alibaba Cloud who are users on credit control can enable the "Write off past bills" feature. This allows the Billing Account to be used to pay off historical unsettled bills. After this feature is enabled, the system automatically writes off past bills in the order they were generated.
Why can't I select accounts for transfer and settlement?
In Alibaba Cloud Cost Management, both the transfer and Unified Settlement features require you to establish a valid financial management relationship between a main account and a sub-account. You can set this up in the Billing Account > Manage Billing Accounts section.
