You can create invoices for teams registered for your tournament, regardless of their status. Invoicing and team approval are two separate and independent processes. Invoicing can be carried out without blocking the approval process, and you can choose the amount to be invoiced, without being limited to the tournament amount. Currently, there are two types of invoicing: tournament and other. Please find enclosed the documentation related to tournament invoicing.
