Send updated invoice PDF to customer and set due date

Your invoices lack order references and due dates, causing customer confusion and extra billing work. It appends order references, sets due dates, and emails invoice PDFs so payments arrive sooner.

Overview

When invoices lack order context, customers delay payment and billing staff spend time chasing details. This flow enriches invoices with order references, sets due dates, and emails the PDF so billing sends correct invoices within hours and reduces follow-ups.
