FOCUS column
BillingAccountId
The identifier of the billing account the charge was invoiced to: the account, agreement or profile that receives the invoice and pays it. It is the top of the account hierarchy for cost purposes. In AWS it is the payer (management) account, in Azure the billing account or billing profile, in Google Cloud the billing account. Every row carries exactly one.
Example
An AWS organization with one payer account puts its 12-digit payer account id here on every row, whichever member account incurred the charge.
Where it comes from, per export
The export column that feeds BillingAccountId in each format the platform ingests, and the transform applied. A format with no row does not carry the column; the value is then absent rather than guessed.
| Export | Source column | Transform |
|---|---|---|
| AWS Data Exports, FOCUS | BillingAccountId | as is |
| Azure Cost Management, FOCUS export | BillingAccountId | as is |
| Azure Cost Details (actual cost) | BillingAccountId | as is |
| Azure Cost Details (amortized cost) | BillingAccountId | as is |
| Google Cloud detailed billing export | billing_account_id | as is |
How Runcost uses it
Runcost reconciles each billing account to its own invoice before combining providers, so a total that does not add up is caught at the source.
