Q: What is Consolidated Billing?

Consolidated Billing enables you to consolidate payment for multiple AWS accounts within your company by designating a single paying account. Consolidated Billing enables you to see a combined view of AWS costs incurred by all accounts, as well as obtain a detailed cost report for each of the individual AWS accounts associated with your “Paying Account”. Consolidated Billing is offered at no additional charge. To learn about consolidated billing, see our Consolidated Billing Guide.

Q: How are Paying Account bills computed?

We aggregate usage of the Linked Accounts and apply pricing to generate the Paying Account’s bill. This is done to give the full benefit of price tiers (lower rates from volume) to the Paying Account. The Paying Account’s bill is the real bill and represents charges due from the customer who owns the Paying Account.

Q: How are line items on the Paying Account's bill allocated across Linked Accounts?

We proportionally 'allocate' costs to Linked Accounts from line items on the Paying Account’s bill. 'Allocated' charges in Linked Accounts are therefore derived from line items in the Paying Account. Allocated costs are computed and stored with a precision of 6 decimal places. When composing the bill for the Paying Account, we apply our line item rounding rules. The allocated costs are retained at the precision of 6 decimal places.

Q: What rounding rules are applied when composing a Paying Account's bill?

We apply the following rounding rules to each line item in a bill.

  • Round UP to the first penny – amounts between $0.000001 and $0.01 are rounded up to $0.01. For example, $0.001 is rounded up to $0.01.
  • Round HALF UP amounts greater than $0.01 - we round down if the fractional amount is less than half a penny, and round up otherwise. For example $0.102 is rounded to $0.10, $0.105 is rounded to $0.11, and $0.107 is rounded to $0.11.

Q: Will Paying Account bills reconcile with Linked Account allocations?

No, a difference may result from any of these factors:

  • Allocated costs have a precision of 6 decimal places while line items are rounded to two decimal places when composing a bill.
  • Line items are rounded UP to the first penny, while allocated costs are not. This can introduce a difference of (almost) a penny between allocated cost and the corresponding line item.
  • On the Portal Activity by Account tab, the allocated costs are rounded to two decimal places. The page provides roll ups at Account and Account-Product levels. There can be a discrepancy between the finer grain allocated costs and the roll-ups.

Q: Can line items in Paying Account bills be greater than the sum of the allocated costs in Linked Account bills?

Yes. In the example below, the line item amount is $0.01 while the sum of allocated costs is $0.00.

  Amount before rounding Amount after rounding
Line item on bill $0.002 $0.01
Allocated cost for account A $0.001 $0.00
Allocated cost for account B $0.001 $0.00

Q: Can lines item in Paying Account bills be less than the sum of the allocated costs in Linked Account bills?

Yes. In the example below, the line item amount is $0.01 while the sum of allocated costs is $0.02.

  Amount before rounding Amount after rounding
Line item on bill $0.014 $0.01
Allocated cost for account A $0.007 $0.01
Allocated cost for account B $0.007 $0.01

Q: Is there a report that gives me breakdown by Linked Account?

Consolidated Billing customers can download a comprehensive report from the Account Activity page.

Q: What types of usage and charges are reflected in the metrics sent from Billing to Amazon CloudWatch?

Usage charges and recurring fees for AWS products and services are included in the EstimatedCharges metrics. You will have a metric for total AWS charges, as well as one additional metric for each AWS product or service that you use. One-time charges and refunds are not included.

Q: Can I set an alert on an AWS product or service that I have not started using yet?

Billing data is only sent to Amazon CloudWatch for AWS products and services that you have used in the current billing cycle. For setting billing alerts, you will not see the option to choose products and services that you do not use.

Q: After I enable monitoring, how long will it take before I can see estimated charges as metric data in Amazon CloudWatch?

Please allow up to 15 minutes for metric data to be visible in Amazon CloudWatch after you enable monitoring of your estimated charges. Immediately after enabling monitoring, you will be able to set a billing alert on your total AWS charges, but in order to set an alert for individual products, services, and accounts that you use, you just wait for metric data to be visible.

Q: Can I use this metric data to view a history of my estimated charges?

Yes. Amazon CloudWatch will store your estimated charges as metric data starting from the time you first enable monitoring. These data remain visible for 14 days. You can use this to view your previous estimated charges. However, estimated charges calculated before you enabled monitoring will not be available in Amazon CloudWatch.

Q: Why do I only see 14 days of estimated charge history?

Amazon CloudWatch stores metric data for 14 days by default.

Q: As a Consolidated Billing customer, can I monitor charges for individual accounts?

Yes, each individual account that is linked to your Consolidated Billing paying account will have individual estimated charge metrics. Paying accounts can access metrics and set alerts for each individual linked account's charges as well as for the consolidated total, including charges for each product and service used by each account. An individual linked account can access metrics and set alerts for only the charges and service usage that are allocated to it. Paying and linked accounts manage their billing alerts independently. When you link an account to Consolidated Billing, you can monitor the total charges associated with the account. Additional metrics are also provided separately for charges accrued both before and after linking it, so you can monitor those charges separately. This is also true when you unlink an account from Consolidated Billing. These additional metrics continue for the remainder of the month in which you link or unlink it. In subsequent months when the account’s role no longer changes, you will only need to monitor the total charges and the additional separated metrics are no longer provided.

Q: Are AWS Marketplace charges included?

Yes, if you use AWS Marketplace, you will have a metric for total AWS Marketplace software charges. Metrics are not provided for individual AWS Marketplace products. AWS ‘infrastructure’ usage charges associated with your AWS Marketplace usage are included in your non-marketplace metrics.

Q: Is tax reflected in the estimated charges monitored by Amazon CloudWatch?

VAT is included for EU customers. US sales tax is not included.

Q: Are credits reflected in the estimated charges monitored by Amazon CloudWatch?

Yes, credits and adjustments will be reflected as updates to estimated charges after they are applied. However, there is not a separate metric for credits and adjustments.

Q: Are refunds reflected in the estimated charges monitored by Amazon CloudWatch?

No. Refunds for prior billing periods are applied directly to your account based on your payment method, and are not reflected in your estimated charges.

Q: Can IAM users view estimated charges and set billing alerts using Amazon CloudWatch?

Yes. In order to give IAM users access to view estimated charge metric data, add Amazon CloudWatch read-only permissions to their IAM policy. In order to allow IAM users to set up billing alerts, add read/write permissions. If you have created an IAM user with permission to view your Account Activity page, you will still need to provide them with permission to use CloudWatch if you want them to be able to set up billing alerts.

Note that any IAM user who has read-only or read/write permission to Amazon CloudWatch can view your estimated charges.

Q: How many alert e-mails will I receive when estimated charges exceed my threshold?

You will receive one e-mail notification when your estimated charges exceed the threshold you set. You will not receive additional e-mails unless you increase your threshold, or until you cross the threshold again in the next billing period.

Q: Can I set billing alerts on charges that I incur at a region-level detail?

Not at this time.

Q: Can I view estimated charge metrics or set billing alerts in a region other than US-East?

Not at this time. The US-East (Virginia) region stores Amazon CloudWatch metrics and alarms for worldwide estimated charges.

Q: Are estimated charges a prediction of my bill at the end of the month?

No, estimated charges only reflect current charges incurred based on the usage that you have already performed that has been processed by AWS billing system. Your Account Activity page will show the date and time of the most recent activity included for estimated charges. Estimated charges typically increase as the month goes on. Your actual bill at the end of the month may be different from the estimated charges that you see during the month.

Q: What happens when I set a payment currency preference for my AWS account?

You will be able to see your estimated bills and pay your AWS invoices in your preferred currency.

Q: Which currencies can I choose from?

AUD – Australian Dollar

CAD - Canadian Dollar

CHF – Swiss Franc

DKK – Danish Krone

EUR – Euro

GBP – British Pound

HKD – Hong Kong Dollar

JPY – Japanese Yen

NOK – Norwegian Krone

NZD – New Zealand Dollar

SEK – Swedish Krona

USD – United States Dollar

ZAR – South African Rand

Q: How can this service help me?

Many customers pay foreign transaction fees when they use their credit cards for cross border transactions. We’ve worked hard to provide competitive rates, but you should compare our rates with your credit card statements to determine if using our currency conversion service is right for you.

Q: Where can I change the payment currency preference for my AWS account?

You can choose your payment currency in the Account Settings section of the Billing Console.

Q: If I change my payment currency, how quickly will that change take effect?

Your account is immediately updated.

Q: What if I change my mind about using the payment currency feature?

You can switch back to USD billing at any time by selecting USD as your payment currency preference.

Q: What currency will be used for pricing the AWS services?

The AWS services will continue to be priced in US Dollars, as usual, unless explicitly noted.

Q: What currency will be used for invoicing/billing?

The line items on invoices will be displayed in US Dollars. Only the invoice total will be converted into your preferred payment currency.

Q: What exchange rate will be used to convert my USD bill to my preferred payment currency?

Rates change daily. The rate applied to your invoice will be the current rate at that time your invoice is created. You can check the current rate on the Billing Console.

Also, due to the nature of the AWS Bill Run process, where bills are generated over a time window, customers may receive invoices with slightly different exchange rates if one or more of the invoices cross the threshold where we update the daily exchange rates.

Q: Am I guaranteed to be charged in my preferred currency once I set my preference?

We will make every effort to charge your card in your preferred currency. However, eligibility depends on the payment instrument and some credit cards are not supported. Ineligible cards can only be charged in USD.

Q: What payment cards are eligible for this program?

Visa and MasterCard credit and debit cards

Q: Why aren’t other payment cards supported?

Amazon Currency Converter is currently supported by Visa and MasterCard credit and debit cards. We continue to work with other card networks to expand eligible payment methods for our customers.

Q: Are all my invoices eligible for currency conversion?

Marketplace and DevPay invoices are not currently eligible for this service and will be processed in USD.

Q: Will I be able to select a payment currency that is different than the base currency of my payment card (e.g. choose to charge a credit card in Euro even if the card is a GBP credit card)?

Yes. You will be able to choose any supported currency as a preferred currency, even a currency that is different than the base currency for the payment card. If you choose a payment currency that differs from the card currency you may be charged foreign conversion charge and fees by your bank.

Q: Does AWS perform the currency conversion?

No, currency conversion is provided by Amazon Services LLC.

Q: I entered my payment method several hours ago. Why am I still unable to use AWS Services like EC2 and S3?

Please check the email address associated with your AWS account and see if you have received any additional information about your account activation from AWS.

Alternatively, please take a moment to verify the credit card details you have on your account that might be causing a delay. Here are the more common reasons why the verification of your payment information may be delayed:

  • Your name and address are incorrect on the card
  • The card number and expiration date are incorrect
  • Your bank has a daily or overall limit that has been exceeded
  • Your bank requires action due to the timing or nature of the charge, and requires that you contact them to verify payment

Troubleshooting Tips

  1. Do you think there is a typo in the payment method information we have on file? Try re-entering your credit card information and then waiting several minutes to see if that resolves the issue.
  2. If this doesn’t resolve the issue, check your financial institution account activity and see if there is a $1 authorization (this is not a charge). If there is not, or there is a $1 entry with a note that you need to contact your financial institution, you may need to contact them to approve the authorization. When this is complete, re-try your credit card authorization and wait several minutes to see if that resolves the issue.
  3. If this is still not solving the problem, then contact us, and please share what troubleshooting you did to resolve the issue so that we can avoid asking you to take actions you have already completed. (Please DO NOT send us any credit card information.)
