Google Cloud Billing report
When comparing the total cost in your monthly invoice with that in the Google Cloud Billing report, you are likely to see discrepancies due to the fact that DoiT recalculates the Google billing data to apply DoiT discounts, custom pricing, and other relevant items.
To build a Cloud Analytics report that strips out DoiT recalculation and closely matches the Cloud Billing report, you need to make adjustments on both sided.
Starting January 1, 2026, DoiT auto-forwards promotional credits from Google Cloud to eligible customers by default. See Promotional credits.
Starting with the March 2026 invoices (issued in April), DoiT transitions Google Cloud billing from a usage_start_time basis to an invoice.month basis. This change ensures that DoiT invoices fully align with Google’s invoicing cycle and data. See example reports of invoice month for how to verify your billing during this transition.
