The correct answer is C. Migrate the acquired company's projects into your company's GCP organization. Link the migrated projects to your company's billing account.

Explanation:

To consolidate all costs onto a single invoice, you need to ensure that the projects from both companies are linked to the same billing account. The simplest and most direct approach to achieve this is to:

Migrate the acquired company's projects into your company's GCP organization, which will allow you to have centralized management.
Link those migrated projects to your company's existing billing account, ensuring all GCP costs are invoiced together.

This approach avoids the complexity of managing multiple billing accounts and allows you to consolidate the charges onto a single invoice for both organizations.

Why the other options are less suitable:

A. Link the acquired company's projects to your company's billing account: While this would link the projects to the billing account, it doesn’t consolidate the organizations themselves. The billing account can only invoice for the projects within the same organization. Projects from two different organizations cannot be fully consolidated this way unless the acquired company's projects are migrated into your company's organization.
B. Configure the acquired company's billing account and your company's billing account to export the billing data into the same BigQuery dataset: This solution does not directly consolidate the billing in terms of a single invoice. While you could analyze the billing data in BigQuery together, the costs would still be invoiced separately.
D. Create a new GCP organization and a new billing account. Migrate the acquired company's projects and your company's projects into the new GCP organization and link the projects to the new billing account: This approach would result in unnecessary complexity. You already have an existing billing account, and there is no need to create a new organization and billing account. Migrating all projects into a new organization would not be required unless there’s a specific business need for a new setup.
