Use this tab window to enter additional information about the other payer and about the relation between the customer and other payer.
The other payer is usually another customer i.e. another customer that will pay the customer's invoices. If this is done, you can also specify who will get reminders and/or interest invoices, the customer or the payer. When an other payer is specified, the payments can be done by the other payer regardless of whichever customer receives the invoice.
