Statements usually finalize between the 1st and the 10th of the month.
Typically CloudHealth waits for Cloud Providers to produce their finalized statements before we finalize the CloudHealth generated statements within the Partner Platform.
If they are not finalized by the 10th it is likely that something is blocking the finalization (eg. the result of an account migration, Cloud Provider invoicing issues, or PGB billing block errors).
If you still notice that the status of a statement for a previous month is set to 'Estimated' then please raise a support ticket to investigate what the issue could be.
