Maxio Proforma Invoices API
The Proforma Invoice object is a preview of an upcoming invoice, showing the charges a customer will be billed before the actual invoice is issued. A proforma invoice is not a finalized billing document and is commonly used to give customers advance visibility into what they owe.
