Hi,

In Odoo, when you work for multiple customers such as Company A, B, and C but want all invoices to be issued to a different company, such as Company D, you can achieve this by configuring the invoicing partner relationship. The idea is that A, B, and C remain your operational customers, meaning that projects, tasks, sales orders, or product deliveries are created under them. However, instead of generating invoices directly to these companies, you redirect invoicing to Company D, who is your actual debtor.

To set this up, you edit each of the customer records for Company A, B, and C in the Contacts module. In their accounting or sales configuration tabs, you define Company D as their invoicing partner. Once this relationship is saved, any transaction such as a sales order, project work, or timesheet logged against A, B, or C will automatically generate an invoice addressed to Company D. This ensures your operational data stays tied to the correct customer while the financial aspect is consolidated under a single debtor.

When you test the flow, creating a sales order for Company A and generating the invoice will result in an invoice billed to Company D. The invoice can still carry references to Company A’s project or work, allowing transparency about which operational customer the work was performed for. If needed, analytic accounts or customer reference fields can be used for further reporting and tracking. This setup keeps invoicing streamlined while maintaining full visibility of your activities per company.

Hope it helps
