Track open items systematically
Dunning is created from open, overdue invoices, linked to the source document. Text templates and dunning levels are configured per tenant; sending and PDF work like other document types. The dunning PDF can show the same GiroCode as the invoice, with the outstanding amount including the dunning fee.
That keeps dunning in ERP context instead of separate Word templates or external dunning tools that do not know which invoice is already partially paid.
