The BILLING OVERVIEW tab lists all invoices with:
Invoice number
Period start and end dates
Status of the invoice

In this example, one invoice is pending, one invoice is currently open, one invoice is past due, and two invoices have been paid:

Download Utilization to download a summary of bucket utilization in a CSV file.
When you download billable utilization statistics in a CSV file, information will be similar to the example below. Each row of the table represents a different bucket. Previously deleted buckets are also listed in this CSV file (the example has duplicate bucket names for that reason). It will take up to 24 hours for a new bucket to be listed. (A billing cycle that runs every 24 hours needs to be completed at least once for the bucket to be available in the CSV.)
Each row includes:
Bucket—Bucket name.
BucketNum—System-wide internal bucket number.
StartTime—Start of the measurement period (in UTC time).
EndTime—End of the measurement period (in UTC time).
RawActiveStorageGBDays—Sum of the number of gibibyte-days (GiB) of the objects during the invoice period. Wasabi invoices in units of GiB-days to account for the passage of time because storage, which will fluctuate over time, is measured daily during the 30-day monthly period.
BillableActiveStorageGBDays—Total number of storage gibibyte-days and associated metadata consumed by all Active Storage objects in the bucket during the invoice period.
BillableDeletedStorageGBDays—Total number of storage gibibyte-days and associated metadata consumed by all Deleted Storage objects in the bucket during the invoice period (storage that has not yet met the 90-day minimum storage period).
NumAPICalls—Number of API calls against the bucket.
IngressGB—Number of ingress (upload) gibibytes against the bucket.
EgressGB—Number of egress (download) gibibytes against the bucket.
For more information, refer to a description of how Wasabi uses GiB (gibibyte) for billing calculations.
