Question

A retail company runs three separate business units, each with its own Google Cloud projects. Finance wants a single monthly invoice for all business units while still being able to see the individual spend attributed to each unit. Which approach best meets these requirements?

Accepted Answer

Link all projects across the three business units to one Cloud Billing account, and use labels or project-level breakdowns to attribute spend per unit.

Answer

Create a separate Cloud Billing account for each business unit so each receives its own invoice, then manually add the totals together each month.

Answer

Move all workloads into a single project so that only one project's costs need to be tracked and billed.

Answer

Use a budget alert on each project and treat the sum of the alert thresholds as the company's monthly invoice.
