FOCUS column
BillingPeriodEnd
The exclusive end of the billing period: the first instant that belongs to the next period. Together with BillingPeriodStart it defines the invoice interval precisely, so that a charge on the boundary lands in exactly one period and totals never double-count.
Example
For the September 2026 invoice the value is 2026-10-01T00:00:00Z, the first moment of October.
Where it comes from, per export
The export column that feeds BillingPeriodEnd 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 | BillingPeriodEnd | as is |
| Azure Cost Management, FOCUS export | BillingPeriodEnd | as is |
| Azure Cost Details (actual cost) | BillingPeriodEndDate | parsed as a date (MM/dd/yyyy) |
| Azure Cost Details (amortized cost) | BillingPeriodEndDate | parsed as a date (MM/dd/yyyy) |
| Google Cloud detailed billing export | Not carried | — |
How Runcost uses it
Runcost uses the pair to validate that an export covers a whole period before reconciling it to the invoice.
