Invoicing for Team with less than 10 members

Hi dear, 

since our Miro cost will be charged on a financed project, we would need to clearly track all expenses, providing invoices and proofs of payment. So I was wondering how invoicing would work for a 9 members team (knowing that self-serve invoicing is available just for 10+  team):

• Will I (as team admin) receive anyway an invoice from Miro or not? If not, how the payment process would happen?
• The post-payment invoice will be still available also for our (small) team?

Thank you!
