Remit-to addresses ensure global electronic invoice compliance. To meet compliance regulations for most countries outside of the US, an invoice must include a remit-to address and associated tax information. If you want to do business with a customer who enabled compliant invoicing, you need to provide the necessary information.
You can specify/manage remit-to addresses when setting up (adding legal entities for) electronic invoicing. See Setting up E-Invoicing for more info.
On the left of the Admin page, click on the Remit-To link to view the list of remit-to addresses and their details, for example, the customers they are assigned to.
