The account or billing entity used to address and route an invoice. It tells billing where the invoice needs to go so it reaches the right processing team.
An example
An order names Northstar Singapore as the customer but directs invoices to the group’s shared-services billing account, with a purchase-order reference. That routing instruction does not by itself change the contracting party.
What to check
Invoice routing and contractual responsibility are different questions. Confirm the named entity and billing instructions.
In practice
Confirm the invoice name, address, required references and delivery route. If the bill-to details and agreement name differ, make the relationship explicit before issuing an invoice.
